In this paper I apply the concept of _inter-Model Inconsistency in Set Theory_ (MIST), introduced by Carolin Antos (this volume), to select positions in the current universe-multiverse debate in philosophy of set theory: I reinterpret H. Woodin’s _Ultimate L_, J. D. Hamkins’ multiverse, S.-D. Friedman’s hyperuniverse and the algebraic multiverse as normative strategies to deal with the situation of de facto inconsistency toleration in set theory as described by MIST. In particular, my aim is to (...) situate these positions on the spectrum from inconsistency avoidance to inconsistency toleration. By doing so, I connect a debate in philosophy of set theory with a debate in philosophy of science about the role of inconsistencies in the natural sciences. While there are important differences, like the lack of threatening explosive inferences, I show how specific philosophical positions in the philosophy of set theory can be interpreted as reactions to a state of inconsistency similar to analogous reactions studied in the philosophy of science literature. My hope is that this transfer operation from philosophy of science to mathematics sheds a new light on the current discussion in philosophy of set theory; and that it can help to bring philosophy of mathematics and philosophy of science closer together.

Hamkins’ multiverse view is a prominent position on the nature of set theory. It is posited against the universe view and proposed as a philosophical theory explaining current set-theoretic practice. This paper confronts the multiverse view with the results of an interview study investigating current set-theoretic practice. The study reveals a heterogeneity of set-theoretic research practices. The multiverse view is found to align well with pluralist research practices but not with absolutist practices. The generalisation claim (...) of the multiverse view fails because of this heterogeneity; only a reduced interpretation of the multiverse view might hold generally. Furthermore, Hamkins’ prediction that the community as a whole will not adopt axioms deciding the continuum hypothesis is found probably true, but for different reasons: although part of the community has already accepted axioms beyond ZFC, another part of the community will withdraw from doing so. In conclusion, I argue that Hamkins’ multiverse view is best interpreted as a valuable perspective on pluralist set-theoretic practices. (shrink)

Multiverse Views in set theory advocate the claim that there are many universes of sets, no-one of which is canonical, and have risen to prominence over the last few years. One motivating factor is that such positions are often argued to account very elegantly for technical practice. While there is much discussion of the technical aspects of these views, in this paper I analyse a radical form of Multiversism on largely philosophical grounds. Of particular importance will be an (...) account of reference on the Multiversist conception, and the relativism that it implies. I argue that analysis of this central issue in the Philosophy of Mathematics indicates that Radical Multiversism must be algebraic, and cannot be viewed as an attempt to provide an account of reference without a softening of the position.

As a candidate theory of quantum gravity, the popularity of string theory has waxed and waned over the past four decades. One current source of scepticism is that the theory can be used to derive, depending upon the input geometrical assumptions that one makes, a vast range of different quantum field theories, giving rise to the so-called landscape problem. One apparent way to address the landscape problem is to posit the existence of a multiverse; this, however, (...) has in turn drawn heightened attention to questions regarding the empirical testability and predictivity of string theory. We argue first that the landscape problem relies on dubious assumptions and does not motivate a multiverse hypothesis. Nevertheless, we then show that the multiverse hypothesis is scientifically legitimate and could be coupled to string theory for other empirical reasons. Looking at various cosmological approaches, we offer an empirical criterion to assess the scientific status of multiverse hypotheses. (shrink)

Cosmological models that invoke a multiverse - a collection of unobservable regions of space where conditions are very different from the region around us - are controversial, on the grounds that unobservable phenomena shouldn't play a crucial role in legitimate scientific theories. I argue that the way we evaluate multiverse models is precisely the same as the way we evaluate any other models, on the basis of abduction, Bayesian inference, and empirical success. There is no scientifically respectable way (...) to do cosmology without taking into account different possibilities for what the universe might be like outside our horizon. Multiverse theories are utterly conventionally scientific, even if evaluating them can be difficult in practice. (shrink)

This paper explores the idea that human consciousness perceives itself as the "main character" due to the structure of the multiverse. If every decision branches into a new reality, then an individual’s memory and experience are biased toward the timeline where they continue to exist. This could lead to a form of subjective immortality, where consciousness shifts to realities where survival and satisfaction persist. The implications of this perspective are examined through the lenses of quantum mechanics, philosophy, and cognitive (...) psychology. (shrink)

Our universe seems to be miraculously fine-tuned for life. Multiverse theories have been proposed as an explanation for this on the basis of probabilistic arguments, but various authors have objected that we should consider our total evidence that this universe in particular has life in our inference, which would block the argument. The debate thus crucially hinges on how Bayesian background and evidence are distinguished and on how indexical or demonstrative terms are analysed. The aim of this article is (...) to take a step back and examine these various aspects of Bayesian reasoning and how they affect the arguments. The upshot is that there are reasons to resist the fine-tuning argument for the multiverse, but the “this-universe-objection” is not one of them. (shrink)

I examine the claim that theistic and scientific multiverses conflict: the former require that only universes above a certain threshold of value exist, while the latter make no such stipulations. I explore several avenues of reconciliation: appealing to ceteris peribus conditions ostensibly inherent within scientific theories, redefining `universe' in the philosophical context, advocating skeptical theism, contending that God and gratuitous evil are compatible, and adjusting the relevant scientific theories. I conclude that only the last strategy is viable, as long as (...) we grant the coherence of a Molinist account of divine providence. If successful, it would entail that scientific and theistic models conflict only superficially. If not, however, then the theistic multiverse is inconsistent with its scientific counterparts.

While the present information ecosystem is still undergoing a tsunami of repeated algorithmic superintelligence (ASI) achievement claims linked to the motif of the epistemic perpetuum mobile (EPM), will the laterally emerging and slowly propagating quantum ASI hype finally lead to a multiversal fear of missing out? Instead of adding novel entries to the already large enough and growing set of prophecies about the future promulgated in the deepfake era, this paper written for purposes of self-education utilizes a recent epistemic complexity (...) theory to answer the following natural scientific question: could the impossibility to build a multiversal ASI be amenable to experimental problematization?

Penelope Maddy has recently addressed the set-theoretic multiverse, and expressed reservations on its status and merits ([Maddy, 2017]). The purpose of the paper is to examine her concerns, by using the interpretative framework of set-theoretic naturalism. I first distinguish three main forms of 'multiversism', and then I proceed to analyse Maddy's concerns. Among other things, I take into account salient aspects of multiverse-related mathematics , in particular, research programmes in set theory for which the use of the (...) multiverse seems to be crucial, and show how one may provide responses to Maddy's concerns based on a careful analysis of 'multiverse practice'.

In this article, I survey some philosophical attitudes to talk concerning `the' universe of sets. I separate out four different strands of the debate, namely: (i) Universism, (ii) Multiversism, (iii) Potentialism, and (iv) Pluralism. I discuss standard arguments and counterarguments concerning the positions and some of the natural mathematical programmes that are suggested by the various views.

In Everettian quantum mechanics, justifications for the Born rule appeal to self-locating uncertainty or decision theory. Such justifications have focused exclusively on a pure-state Everettian multiverse, represented by a wave function. Recent works in quantum foundations suggest that it is viable to consider a mixed-state Everettian multiverse, represented by a (mixed-state) density matrix. Here, we develop the conceptual foundations for decoherence and branching in a mixed-state multiverse, and extend arguments for the Born rule to this setting. (...) This extended framework provides a unification of 'classical' and 'quantum' probabilities, and additional theoretical benefits, for the Everettian picture. (shrink)

This paper shows that several live philosophical and scientific hypotheses – including the holographic principle and multiverse theory in quantum physics, and eternalism and mind-body dualism in philosophy – jointly imply an audacious new theory of free will. This new theory, "Libertarian Compatibilism", holds that the physical world is an eternally existing array of two-dimensional information – a vast number of possible pasts, presents, and futures – and the mind a nonphysical entity or set of properties (...) that "read" that physical information off to subjective conscious awareness (in much the same way that a song written on an ordinary compact-disc is only played when read by an outside medium, i.e. a CD-player). According to this theory, every possible physical “timeline” in the multiverse may be fully physically deterministic or physically-causally closed but each person’s consciousness still entirely free to choose, ex nihilo, outside of the physical order, which physically-closed timeline is experienced by conscious observers. Although Libertarian Compatibilism is admittedly fantastic, I show that it not only follows from several live scientific and philosophical hypotheses, I also show that it (A) is a far more explanatorily powerful model of quantum mechanics than more traditional interpretations (e.g. the Copenhagen, Everett, and Bohmian interpretations), (B) makes determinate, testable empirical predictions in quantum theory, and finally, (C) predicts and explains the very existence of a number of philosophical debates and positions in the philosophy of mind, time, personal identity, and free will. First, I show that whereas traditional interpretations of quantum mechanics are all philosophically problematic and roughly as ontologically “extravagant” as Libertarian Compatibilism – in that they all posit “unseen” processes – Libertarian Compatibilism is nearly identical in structure to the only working simulation that human beings have ever constructed capable of reproducing (and so explaining) every general feature of quantum mechanics we perceive: namely, massive-multiplayer-online-roleplaying videogames (or MMORPGs). Although I am not the first to suggest that our world is akin to a computer simulation, I show that existing MMORPGs (online simulations we have already created) actually reproduce every general feature of quantum mechanics within their simulated-world reference-frames. Second, I show that existing MMORPGs also replicate (and so explain) many philosophical problems we face in the philosophy of mind, time, personal identity, and free will – all while conforming to the Libertarian Compatibilist model of reality. -/- I conclude, as such, that as fantastic and metaphysically extravagant as Libertarian Compatibilism may initially seem, it may well be true. It explains a number of features of our reality that no other physical or metaphysical theory does. (shrink)

One might suppose that Everettian quantum mechanics (EQM) is inhospitable to metaphysial indeterminacy (MI), given that, as A. Wilson (2020) puts it, "the central idea of EQM is to replace indeterminacy with multiplicity" (77). But as Wilson goes on to suggest, the popular decoherence-based understanding of EQM (henceforth: DEQM) appears to admit of indeterminacy in both world number and world nature, where the latter indeterminacy---our focus here---is plausibly metaphysical. After a brief presentation of DEQM (S1), we bolster the case for (...) there being MI in world nature in DEQM (S2). The remainder of the paper is devoted to a comparative assessment of the two main approaches to MI for purposes of accommodating this MI---namely, a metaphysical supervaluationist approach (as per Barnes and Williams 2011) and a determinable-based approach (as per Wilson 2013 and Calosi and Wilson 2018 and 2021). We briefly describe each approach (S3), then offer arguments in favour of a determinable-based approach to world nature MI in DEQM (S4). (shrink)

In this paper, I argue that a naturalist approach in philosophy of mathematics justifies a pluralist conception of set theory. For the pluralist, there is not a Single Universe, but there is rather a Multiverse, composed by a plurality of universes generated by various set theories. In order to justify a pluralistic approach to sets, I apply the two naturalistic principles developed by Penelope Maddy (cfr. Maddy (1997)), UNIFY and MAXIMIZE, and analyze through them the potential of the (...) set theoretic multiverse to be the best framework for mathematical practice. According to UNIFY, an adequate set theory should be foundational, in the sense that it should allow one to represent all the currently accepted mathematical theories. As for MAXIMIZE, this states that any adequate set theory should be as powerful as possible, allowing one to prove as many results and isomorphisms as possible. In a recent paper, Maddy (2017) has argued that this two principle justify ZFC as the best framework for mathematical practice. I argue that, pace Maddy, these two principles justify a multiverse conception of set theory, more precisely, the generic multiverse with a core (GMH). (shrink)

Our examination of universal origins and fine-tuning will begin with a discussion of infl ationary scenarios grafted onto Big Bang cosmology and the proof that all infl ationary spacetimes are past-incomplete. After diverting into a lengthy critical examination of the “different physics” offered by quantum cosmologists at the past-boundary of the universe, we will proceed to dissect the inadequacies of infl ationary explanations and string-theoretic constructs in the context of three cosmological models that have received much attention: the Steinhardt-Turok cyclic (...) ekpyrotic model (which does not invoke inflation), the Gasperini-Veneziano pre-Big Bang infl ationary model, and the inflationary string landscape model advanced by Susskind, Polchinski, Bousso, and Linde. We will argue that none of these highly speculative string cosmologies removes the necessity of a beginning to the process of universe generation, and we will emphasize the implications of this fact. Then, since the inflationary “mechanism” only really addresses the fi ne-tuning of the initial conditions of the universe and not the conditions embodied in its finely tuned laws and constants, we will analyze the adequacy of the string multiverse in its three versions (cyclic ekpyrotic, pre-Big Bang, and landscape) for explaining the nomological structure and values of these precisely tuned life-compatible universal parameters. When all is said and done, it will be clear that transcendent intelligent agency is not just the only causally suffi cient and therefore metaphysically sound explanation for universal origins and fine-tuning, but it is also much more parsimonious, elegant, and resonant with meaning than all of the ad hoc machinations of multiverse cosmology.

We argue the thesis that if (1) a physical process is mathematically representable by a Cauchy sequence; and (2) we accept that there can be no infinite processes, i.e., nothing corresponding to infinite sequences, in natural phenomena; then (a) in the absence of an extraneous, evidence-based, proof of `closure' which determines the behaviour of the physical process in the limit as corresponding to a `Cauchy' limit; (b) the physical process must tend to a discontinuity (singularity) which has not been reflected (...) in the Cauchy sequence that seeks to describe the behaviour of the physical process. We support our thesis by mathematical models of the putative behaviours of (i) a virus cluster; (ii) an elastic string; and (iii) a Universe that recycles from Big Bang to Ultimate Implosion, in which parity and local time reversal violation, and the existence of `dark energy' in a multiverse, need not violate Einstein's equations and quantum theory. We suggest that the barriers to modelling such processes in a mathematical language that seeks unambiguous communication are illusory; they merely reflect an attempt to ask of the language chosen for such representation more than it is designed to deliver.

Physicists Brian Greene and Max Tegmark both make variants of the claim that if the universe is infinite and matter is roughly uniformly distributed, then there are infinitely many “people with the same appearance, name and memories as you, who play out every possible permutation of your life choices.” In this paper I argue that--while our current best theories in astrophysics may allow one to conclude that we have infinitely many duplicates whose lives are identical to our own from start (...) to finish--without either further advances in physics or advances in fields like biology, psychology, neuroscience, and philosophy, Greene’s and Tegmark’s claims about the ways in which our duplicates lives will differ from our own are not a consequence of our best current scientific theories. Rather, I argue that Greene and Tegmark’s conclusions rely on philosophically imprecise usages of the language of “possibility.”. (shrink)

This paper proposes a novel framework for understanding consciousness as a dynamic navigator of parallel realities, guided by principles of least-action optimization akin to the brachistochrone curve in physics. Rather than moving linearly through time, consciousness may instead be selecting optimal trajectories across a pre-existing structure of potential realities, ensuring continuity and coherence in perceived experience. By drawing parallels to quantum wavefunction collapse, black hole thermodynamics, and Hawking radiation, we explore how dreams may function as a subconscious dissipation mechanism, offloading (...) unresolved cognitive mass in a manner analogous to radiation leakage from a black hole. Furthermore, computational models suggest that consciousness does not select realities randomly but instead follows an energy-minimizing trajectory, favoring paths of least resistance in a way consistent with Lagrangian mechanics and the Euler-Lagrange equation. These findings suggest that reality is not a fixed sequence of events but rather a fluid system of probabilistic timeline selection, where awareness, intention, and subconscious processes influence the unfolding trajectory of experience. This theory provides a new perspective on dreams, time perception, and the mechanics of reality navigation, inviting further exploration into whether consciousness can actively refine its trajectory through directed awareness and mental training techniques.

The primary quantum mechanical equation of motion entails that measurements typically do not have determinate outcomes, but result in superpositions of all possible outcomes. Dynamical collapse theories (e.g. GRW) supplement this equation with a stochastic Gaussian collapse function, intended to collapse the superposition of outcomes into one outcome. But the Gaussian collapses are imperfect in a way that leaves the superpositions intact. This is the tails problem. There are several ways of making this problem more precise. But many authors dismiss (...) the problem without considering the more severe formulations. Here I distinguish four distinct tails problems. The first (bare tails problem) and second (structured tails problem) exist in the literature. I argue that while the first is a pseudo-problem, the second has not been adequately addressed. The third (multiverse tails problem) reformulates the second to account for recently discovered dynamical consequences of collapse. Finally the fourth (tails problem dilemma) shows that solving the third by replacing the Gaussian with a non-Gaussian collapse function introduces new conflict with relativity theory. (shrink)

The maturation of the physical image has made apparent the limits of our scientific understanding of fundamental reality. These limitations serve as motivation for a new form of metaphysical inquiry that restricts itself to broadly scientific methods. Contributing towards this goal we combine the mathematical universe hypothesis as developed by Max Tegmark with the axioms of Stewart Shapiro’s structure theory. The result is a theory we call the Theory of the Structural Multiverse (TSM). The focus is (...) on informal theory development and constraint satisfaction. Some empirical consequences of the theory are worked out, in particular the feasibility of a predictive observer selection effect. The explanatory, unifying, and generative powers of the theory are found to substantially support the theory. The TSM is demonstrated to be an empirically significant scientific theory that is foundational to and continuous with the rest of the scientific image. (shrink)

This is part 1 on a paper whose final variation of parts shall be titled,”The Universal Theory of Existence: The Sashu, Pharaohs, and the al-Mahdī”. The first part of this series sets the premise for a proposed ”Theory of Everything” that will be the foundation for encompassing many different topics. Since, the beginning of time, a singularity existed. This singularity is what we call an origin point of everything. Beyond, this origin point for time is different depending on (...) position, being outside of the singularity, or the idea that multiple universes exists with different time dilation, and likely different laws. Existence in essence is centered around the idea of what is prior to the origin point of time, and in theory, what is the space-time complexity together, in regards to how civilization come to be. From a physics standpoint, there are multiple theories around this. For starters, the author of this paper coined QSOPR Theorem, MDQBT, QSICT, and how this relates to Time/Multiverse Dilation and Origin Points. Quantum Similarity on a molecular, atomic, theoretical, and chemical level is one of these vast things humanity should be trying to explore. (shrink)

Analysis is given of the Omega Point cosmology, an extensively peer-reviewed proof (i.e., mathematical theorem) published in leading physics journals by professor of physics and mathematics Frank J. Tipler, which demonstrates that in order for the known laws of physics to be mutually consistent, the universe must diverge to infinite computational power as it collapses into a final cosmological singularity, termed the Omega Point. The theorem is an intrinsic component of the Feynman-DeWitt-Weinberg quantum gravity/Standard Model Theory of Everything (TOE) (...) describing and unifying all the forces in physics, of which itself is also required by the known physical laws. With infinite computational resources, the dead can be resurrected--never to die again--via perfect computer emulation of the multiverse from its start at the Big Bang. Miracles are also physically allowed via electroweak quantum tunneling controlled by the Omega Point cosmological singularity. The Omega Point is a different aspect of the Big Bang cosmological singularity--the first cause--and the Omega Point has all the haecceities claimed for God in the traditional religions. -/- From this analysis, conclusions are drawn regarding the social, ethical, economic and political implications of the Omega Point cosmology.

We give some arguments for why the Mathematical Universe Hypothesis (MUH) might be too restrictive in its assertions of what can exist, and that the universe/multiverse might be formed by more than what can be expressed mathematically. In particular, we show a thought experiment which indicates that the principle of materialism in general is an inadequate hypothesis of how consciousness appears. Instead we propose a novel approach to solving the problem of consciousness, which is to hypothesize that each universe (...) might have different laws of consciousness, just as they might have different laws of physics. We also show that MUH, without such consciousness laws, and without any other modification, leads to complete chaos for the observers in the multiverse, and therefore cannot hold as it is. We then go on to propose another theory of existence, which does not seem to lead to complete chaos. This theory hypothesizes that the multiverse is the consequence of what we might call the Logic of Everything (LoE) continuously deducing new truths about itself. Lastly, we briefly discuss what fundamental ethics can be derived from this theory, and others like it. (shrink)

This paper attempts to answer the question: “what are the chances that our universe should exhibit the law-like behavior we observe?” It argues that, pace the assertions of advocates of “multiverse theories” in physics, multiverses do not resolve the Fine-Tuning Problem. It makes the case that, given the principle of indifference, we should find it surprising that our universe behaves in a law-like manner.

Scientific Perspectives on Life After Death, Heaven, and Hell -/- Introduction -/- The concepts of life after death, heaven, and hell have been central to human thought for thousands of years, often tied to religious and spiritual traditions. However, modern science seeks to understand these ideas through neuroscience, quantum physics, and cosmology. While traditional scientific views suggest that consciousness ceases at death, emerging theories propose that it may persist in ways not yet fully understood. This essay explores the scientific explanations (...) for life after death, the potential existence of heaven and hell, and how they may fit into our understanding of the universe. -/- 1. The Science of Life After Death -/- The question of what happens after death is deeply connected to the nature of consciousness. Is it purely a product of the brain, or does it exist independently? -/- Neuroscientific Perspective: The Brain as the Seat of Consciousness -/- Neuroscience generally holds that consciousness arises from neuronal activity in the brain. When the brain dies, consciousness ceases. -/- Near-Death Experiences (NDEs)—where people report floating above their bodies, seeing a tunnel of light, or meeting deceased loved ones—are often attributed to oxygen deprivation, neurotransmitter surges, or altered brain states. -/- Quantum Consciousness: Does Awareness Continue Beyond Death? -/- Physicist Roger Penrose and anesthesiologist Stuart Hameroff propose that consciousness arises from quantum processes in microtubules within brain cells. -/- If consciousness is quantum-based, it may not be limited to the body and could persist in the quantum field after death, providing a possible explanation for an afterlife. -/- Simulation Hypothesis & Digital Immortality -/- Some physicists suggest that the universe might be a simulation, meaning consciousness could be transferred or stored after death like data in a computer. -/- Advanced civilizations (Type III–V on the Kardashev scale) could potentially upload minds into artificial environments, creating an afterlife experience similar to religious beliefs. -/- 2. Scientific Explanations for Heaven and Hell -/- The traditional view of heaven and hell describes them as places of eternal reward or punishment. Science offers alternative explanations based on psychology, physics, and cosmic phenomena. -/- Heaven and Hell as Psychological States -/- Neuroscience suggests that heaven and hell might not be places but mental states. -/- Psychedelic substances like DMT (dimethyltryptamine) and psilocybin can induce extreme euphoria (heaven-like states) or terrifying hallucinations (hell-like experiences). -/- This suggests that the brain can generate experiences resembling religious descriptions of the afterlife. -/- Multiverse Theory: Heaven and Hell as Parallel Realities -/- Some physicists propose that we live in a multiverse—a reality where multiple dimensions or parallel universes exist. -/- If consciousness can transition between dimensions, then what some interpret as “heaven” or “hell” could be another level of existence rather than mere mythology. -/- Cosmological Perspective: Black Holes and the Afterlife -/- A black hole could be viewed as a “hellish” state, where time slows to infinity as one is stretched and crushed by gravity. -/- Conversely, a sufficiently advanced civilization (Type V) could create a simulated paradise, a form of engineered “heaven.” -/- 3. Can Science Ever Prove Life After Death? -/- Although science has not confirmed an afterlife, future discoveries might change our understanding: -/- 1. Neuroscience Advances: Brain scans and AI models may one day replicate consciousness, proving whether it can exist beyond death. -/- 2. Quantum Research: If consciousness is linked to quantum mechanics, experiments may detect its persistence after bodily death. -/- 3. Artificial Afterlives: Advanced civilizations may design digital heavens or hells, controlling consciousness beyond biological limits. -/- Conclusion -/- While traditional science suggests that life ends with death, emerging theories from quantum physics, information theory, and cosmology offer intriguing possibilities for an afterlife. Whether through quantum consciousness, multiverse theories, or digital immortality, science continues to explore questions once left to religion. If a Type V civilization exists, it might have the ability to finally answer the mystery of life after death and the existence of heaven and hell. Until then, these remain open questions at the intersection of science, philosophy, and faith. -/- . (shrink)

The Mystery of Existence: Why Does the Universe Exist? -/- Introduction -/- The question of why the universe exists is one of the deepest and most profound mysteries of human thought. It challenges both scientific and philosophical understanding, raising fundamental questions about reality, time, and causality. If the universe had a beginning, what caused it? If it has always existed, how can something be infinite? Even if we accept a scientific explanation such as the Big Bang, we are left wondering: (...) why is there something rather than nothing? -/- Throughout history, different disciplines—science, philosophy, and theology—have attempted to answer this question. Some argue that existence is the result of natural laws, others propose that it is an inexplicable brute fact, while some believe that a higher intelligence is responsible. This essay explores these perspectives to examine the enigma of existence itself. -/- Scientific Perspectives: The Origin of the Universe -/- Modern cosmology provides a well-supported theory of how the universe evolved. The Big Bang Theory states that approximately 13.8 billion years ago, the universe began as an extremely hot and dense point, rapidly expanding and cooling over time. This model explains the structure of the cosmos, including galaxies, stars, and planets. However, it does not explain why the Big Bang happened or what—if anything—existed before it. -/- The Quantum Fluctuation Hypothesis -/- One idea proposed by physicists is that the universe could have emerged from quantum fluctuations. In quantum mechanics, empty space is not truly “empty”; it is filled with energy that can generate temporary particles. Some scientists, such as Stephen Hawking and Lawrence Krauss, have suggested that the universe might have arisen spontaneously due to quantum effects. -/- However, this explanation does not address why quantum laws exist in the first place. Even if the universe came from a quantum fluctuation, the question remains: why do these physical laws exist at all? -/- The Multiverse Hypothesis -/- Another possible explanation is the multiverse theory—the idea that our universe is just one of many. In this view, countless universes exist, each governed by different physical laws. Some might be lifeless, while others could be similar to ours. -/- The multiverse could explain why our universe seems “fine-tuned” for life—because among infinite universes, at least one would inevitably support complex beings like us. However, this raises an even deeper question: why does the multiverse itself exist? Does it require a deeper underlying principle, or is it simply an unexplainable fact? -/- Philosophical Dilemmas: Can Existence Be Explained? -/- Philosophy has long grappled with the mystery of existence. The ancient Greek philosopher Parmenides argued that “nothing” cannot truly exist—therefore, something must always have existed. This suggests that existence is eternal and does not require an explanation. -/- However, Gottfried Wilhelm Leibniz, a 17th-century philosopher and mathematician, posed a crucial question: -/- “Why is there something rather than nothing?” -/- Leibniz proposed the Principle of Sufficient Reason, which states that everything must have an explanation—even the existence of the universe. He suggested that if the universe exists, it must have a necessary cause that exists by its own nature. But what could this necessary cause be? -/- One possibility is that existence is simply a brute fact—it exists without needing an explanation. But this answer is unsatisfying for many philosophers, as it does not provide a deeper understanding of reality. -/- The Role of Consciousness and the Observer -/- Another fascinating idea comes from quantum mechanics, which suggests that observation influences reality. The famous double-slit experiment demonstrates that light and particles behave differently depending on whether they are observed. Some interpretations propose that consciousness plays a fundamental role in shaping the universe. -/- Philosophical idealism, held by thinkers like George Berkeley, argues that reality is mental rather than material. In this view, existence itself might be linked to an observer—perhaps an ultimate consciousness that gives rise to reality. This aligns with some interpretations of quantum mechanics that suggest the universe requires an observer to “collapse” into a definite state. -/- But if consciousness is necessary for existence, then what is the nature of this observer? Is it human consciousness, or something far greater? -/- Theological and Metaphysical Explanations -/- Many religious and metaphysical traditions attempt to explain the existence of the universe through the concept of a divine creator. In this view, God or an ultimate intelligence is the source of all existence. -/- This idea aligns with the notion of necessary existence—the idea that something must exist by its very nature and does not require an external cause. If God exists necessarily, then God could be the ultimate answer to why anything exists at all. -/- However, this raises another question: why does God exist? If God is eternal and self-existent, why is that the case? Some theologians argue that God is the only being whose existence is necessary, while everything else is contingent. But this idea, while conceptually powerful, remains beyond scientific verification. -/- Conclusion: The Limits of Human Understanding -/- The mystery of existence remains one of the greatest unanswered questions. Science explains how the universe functions and possibly how it began, but not why it exists at all. Philosophy challenges our assumptions and explores deep logical possibilities, yet it struggles to provide a definitive answer. Theology and metaphysics offer explanations based on divine intelligence, but these require a leap of faith. -/- Perhaps human cognition is simply not equipped to grasp the ultimate reason for existence. Or perhaps, as our understanding of physics, consciousness, and metaphysics deepens, we may one day come closer to an answer. Until then, the question “Why is there something rather than nothing?” remains an open and profound mystery—one that continues to inspire scientific, philosophical, and spiritual inquiry. -/- .

-/- The Universal Law of Balance in Nature and Its Application to Cosmology -/- The universe, in all its vastness and complexity, follows fundamental principles that govern its formation, structure, and evolution. If the universal law of balance in nature, as formulated by Angelito Malicse, is truly a fundamental law, then it must apply to all physical systems—including cosmology. The cosmos operates through a delicate interplay of opposing forces, equilibrium states, and self-regulating processes. From the expansion of the universe to (...) the formation of galaxies, black holes, and even the quantum realm, we can see how the universe upholds a balance that sustains its existence. -/- The Big Bang and Cosmic Expansion: A Balanced Beginning -/- The Big Bang theory explains that the universe originated from an infinitely dense singularity and has been expanding ever since. This expansion is governed by finely tuned physical constants. If the rate of expansion had been slightly faster, matter would have dispersed too quickly for galaxies to form. If it had been slightly slower, gravitational collapse would have occurred early on. -/- This fine-tuning suggests a natural equilibrium that enables the formation of structured systems rather than chaos or premature collapse. It aligns with the universal law of balance, where natural forces regulate themselves to sustain stability and existence. The very fabric of the universe appears to have been designed to operate within a delicate range, ensuring its continued evolution. -/- Cosmic Inflation and Homeostasis in the Universe -/- During the first moments after the Big Bang, the universe underwent a brief but intense period of cosmic inflation, expanding exponentially faster than the speed of light. This process ensured that energy and matter were evenly distributed, leading to a homogeneous and isotropic universe on large scales. -/- This phenomenon mirrors biological homeostasis, where a system self-regulates to maintain stability. Just as a living organism adjusts internal conditions to sustain life, the universe adjusted its own expansion to ensure long-term structural balance. This aligns with the universal law of balance, demonstrating that even at the largest scale, self-regulation ensures stability. -/- Gravitational Balance in Galactic Formation -/- Galaxies and planetary systems form due to the interplay of gravitational attraction and rotational forces. Gravity pulls matter together, while angular momentum prevents collapse. This balance creates stable systems where stars, planets, and entire galaxies can persist for billions of years. -/- If gravitational forces were too strong, matter would collapse into dense objects too quickly. If too weak, galaxies would never form, and the universe would remain an empty void. This self-sustaining balance echoes the way decision-making works in human societies—where opposing forces (such as economic, social, and political pressures) must be weighed to maintain stability. The universe, much like human systems, thrives through equilibrium. -/- Dark Matter and Dark Energy: Opposing Forces in Equilibrium -/- Approximately 95% of the universe is composed of dark matter and dark energy, two mysterious components that shape cosmic evolution. Dark matter provides the gravitational glue that holds galaxies together, preventing them from flying apart. Dark energy, on the other hand, drives the accelerated expansion of space. -/- These two forces act in opposition, yet their interaction maintains the overall stability of the universe. If dark energy were too dominant, galaxies would tear apart. If dark matter were too dominant, the universe would collapse under its own gravity. This cosmic balance reflects the universal law of balance, where opposing forces must coexist in equilibrium to sustain existence. -/- Thermodynamic Equilibrium and Entropy: Order Within Disorder -/- The second law of thermodynamics states that entropy (disorder) increases over time. Left unchecked, the universe should become a chaotic, unstructured mess. Yet, within this increasing disorder, we see localized structures of order—galaxies, stars, planets, and even life itself. -/- This paradox suggests that while entropy governs the overall system, temporary balance allows complex structures to emerge and persist. Just as societal stability emerges from balancing chaos and order, the cosmos generates structure despite the drive toward disorder. This principle aligns with the universal law of balance, where even in a seemingly random environment, natural forces work to create structured, stable systems. -/- Black Holes and Information Balance -/- Black holes, some of the most extreme objects in the universe, consume matter and energy, seemingly erasing all information about what falls into them. However, modern physics suggests that information is not truly lost—it is preserved in some form, whether encoded on the event horizon (as suggested by the holographic principle) or through quantum processes. -/- This concept aligns with the universal law of balance because it suggests that even in the most extreme environments, information follows a conservation principle. Just as human actions have consequences that persist in various forms, the universe ensures that no energy or information truly disappears, maintaining a deeper cosmic equilibrium. -/- Quantum Cosmology: Balance at the Smallest Scales -/- At the smallest scales of reality, quantum mechanics governs the behavior of particles, where superposition and uncertainty play fundamental roles. In the early universe, quantum fluctuations helped seed the formation of galaxies. -/- These fluctuations demonstrate a balance between uncertainty and structure. Just as human decisions arise from multiple possibilities but follow natural constraints, the universe’s structure emerges from quantum uncertainty within governing physical laws. This suggests that even at the quantum level, the universe operates under a principle of balance. -/- Multiverse Theories and the Balance of Possibilities -/- Some theories suggest that our universe is just one of many in a multiverse, each with different physical laws. If this is true, then our universe may simply be one of the few that has achieved the right balance of forces to sustain structure and life. -/- This supports the idea that cosmic selection could function similarly to natural selection—only universes with stable laws of physics persist. This aligns with the universal law of balance, where systems that maintain equilibrium continue to exist, while those that fail to achieve balance dissolve into nonexistence. -/- Conclusion: A Universe Governed by Balance -/- From the grand scale of cosmic expansion to the microscopic realm of quantum fluctuations, the universe appears to follow the universal law of balance in nature. Every major phenomenon—whether it be the interplay of gravity and expansion, the self-regulation of galaxies, or the emergence of structured systems within entropy—reflects the principle that equilibrium is essential for existence. -/- If this law is truly fundamental, then it not only governs the universe but also human behavior, decision-making, and societal structures. The same balance that sustains galaxies and black holes also shapes civilizations, economies, and individual consciousness. -/- By understanding this universal principle, we can apply it to solve real-world problems. If leaders, scientists, and educators incorporate the law of balance into governance, economics, and education, it could lead to a more stable, sustainable, and just society—just as it has sustained the universe for billions of years. -/- .

The Multiverse Response to the problem of evil has it that God made our universe because God makes every universe meeting a certain standard. The main problem for that response is that there’s no explanation for why God didn’t just keeping making duplicates of perfect universes. This paper introduces the ‘Multiactualities Response’, which says that God actualises every possible world that meets a certain standard of value. It avoids the corresponding problem about duplication because different propositions must always be (...) true at distinct worlds. The Multiactualities Response nevertheless has its own problem, namely that it requires the possibility of multiple actual worlds. This paper argues that if we consider spacetimes with wormholes, we have good cause to think there can be multiple metaphysically privileged present moments; given a suitable analogy between time and modality, it follows that there can be multiple metaphysically privileged (i.e. actual) worlds. This paper includes an in–depth examination of the metaphysics of both the temporal and modal cases. (shrink)

In this paper, I argue that one of the arguments usually put forward in defence of universism is in tension with current set theoretic practice. According to universism, there is only one set theoretic universe, V, and when applying the method of forcing we are not producing new universes, but only simulating them inside V. Since the usual interpretation of set generic forcing is used to produce a “simulation” of an extension of V from a countable set inside V itself, (...) the above argument is credited to be a strong defence of universism. However, I claim, such an argument does not take into account current mathematical practice. Indeed, it is possible to find theorems that are available to the multiversists but that the advocate of universism cannot prove. For example, it is possible to prove results on infinite games in non-well-founded set-theories plus the axiom of determinacy (such as ZF + AFA + PD) that are not available in ZFC + PD. These results, I contend, are philosophically problematic on a strict universist approach to forcing. I suggest that the best way to avoid the difficulty is to adopt a pluralist conception of set theory and embrace a set theoretic multiverse. Consequently, the current practice of set generic forcing better supports a multiverse conception of set theory. (shrink)

Recent research in science indicates that we are living in a fine-tuned universe. Only a very small parameter space of universal fundamental constants in Physics is congenial for the existence of life. Moreover, recent studies in Biological evolution also reveal that fine-tuning did exist in the evolution. It seems that we are so lucky to exist as all universal fundamental constants and life-permitting factors really fall into such a very small life-allowing region. This problem is known as the fine-tuning problem. (...) Does this phenomenon need an explanation? Can the fine-tuning problem point to the existence of God? Modern Science invokes the idea of multiverse to address the fine-tuning problem. Some scientists suggest that each universe in a set of infinitely many universes contains a typical set of fundamental constants. We should not be surprised why our universe is fine-tuned because we would not exist if the constants are not the life-allowed values. Some suggest that the existence of God can explain this fine-tuning problem. The naturalistic multiverse theory and the existence of God are the two most robust proposals to address the fine-tuning problem. Moreover, some argue that the fine-tuning problem is not real because we are just subject to observational selection effect. In this thesis, I will provide a comprehensive discussion on the fine-tuning phenomena in our universe. In particular, I will use the confirmation principle and the inference to the best explanation simultaneously to evaluate different hypotheses in a more systematic way and give some of the new and updated scientific and philosophical arguments to respond to the recent criticisms of the fine-tuning arguments. I conclude that the theistic hypothesis is the best among all to address the fine-tuning problem. (shrink)

We address Steel’s Programme to identify a ‘preferred’ universe of set theory and the best axioms extending ZFC by using his multiverse axioms MV and the ‘core hypothesis’. In the first part, we examine the evidential framework for MV, in particular the use of large cardinals and of ‘worlds’ obtained through forcing to ‘represent’ alternative extensions of ZFC. In the second part, we address the existence and the possible features of the core of MV_T (where T is ZFC+Large (...) Cardinals). In the last part, we discuss the hypothesis that the core is Ultimate-L, and examine whether and how, based on this fact, the Core Universist can justify V=Ultimate-L as the best (and ultimate) extension of ZFC. To this end, we take into account several strategies, and assess their prospects in the light of MV’s evidential framework. (shrink)

Leibniz said that the universe, if God-created, would exist at a unique, conjoint, physical maximum: Of all possible worlds, it would be richest in phenomena, but its richness would arise from the simplest physical laws and initial conditions. Using concepts of ‘‘variety’’ and algorithmic informational complexity, Leibniz’ claim can be reframed as a testable theory. This theory predicts that the laws and conditions of the actual universe should be simpler, and the universe richer in phenomena, than the presence (...) of observers would require. Tegmark has shown that inhabitants of an infinite multiverse would likely observe simple laws and conditions, but also phenomenal richness just great enough to explain their existence. Empirical observations fit the claim of divine choice better than the claim of an infinite multiverse. The future of the universe, including its future information-processing capacity, is predicted to be endless. -/- . (shrink)

Set-theoretic pluralism is an increasingly influential position in the philosophy of set theory (Balaguer [1998], Linksy and Zalta [1995], Hamkins [2012]). There is considerable room for debate about how best to formulate set-theoretic pluralism, and even about whether the view is coherent. But there is widespread agreement as to what there is to recommend the view (given that it can be formulated coherently). Unlike set-theoretic universalism, set-theoretic pluralism affords an answer to Benacerraf’s epistemological challenge. The purpose of this paper (...) is to determine what Benacerraf’s challenge could be such that this view is warranted. I argue that it could not be any of the challenges with which it has been traditionally identified by its advocates, like of Benacerraf and Field. Not only are none of the challenges easier for the pluralist to meet. None satisfies a key constraint that has been placed on Benacerraf’s challenge. However, I argue that Benacerraf’s challenge could be the challenge to show that our set-theoretic beliefs are safe – i.e., to show that we could not have easily had false ones. Whether the pluralist is, in fact, better positioned to show that our set-theoretic beliefs are safe turns on a broadly empirical conjecture which is outstanding. If this conjecture proves to be false, then it is unclear what the epistemological argument for set-theoretic pluralism is supposed to be. (shrink)

The new understanding of basic dimensions Absolute Time and Space will open the possibility of exploring beyond our current known Universe. These absolute dimensions might supersede our current Spacetime dimension and related theories. Interpretations based on these dimensions could effectively bridge the gap between theories of microscopic and telescopic worlds and it will eventually give us a better picture of our Universe. This book will take us one step closer towards the understanding of our Entire Existence. As we can see (...) below mentioned are some of the current research related topics in the field of Metaphysics and Cosmology. This book will address all these questions and related subsequent questions of this subject. 1. How our universe came into existence? 2. What was the time before the start of the universe? 3. Is there anything outside of this universe? 4. Is time travel possible? 5. Is there any multiverse or parallel universe? (shrink)

A central area of current philosophical debate in the foundations of mathematics concerns whether or not there is a single, maximal, universe of set theory. Universists maintain that there is such a universe, while Multiversists argue that there are many universes, no one of which is ontologically privileged. Often model-theoretic constructions that add sets to models are cited as evidence in favour of the latter. This paper informs this debate by developing a way for a Universist to interpret talk (...) that seems to necessitate the addition of sets to V. We argue that, despite the prima facie incoherence of such talk for the Universist, she nonetheless has reason to try and provide interpretation of this discourse. We present a method of interpreting extension-talk (V-logic), and show how it captures satisfaction in `ideal' outer models and relates to impredicative class theories. We provide some reasons to regard the technique as philosophically virtuous, and argue that it opens new doors to philosophical and mathematical discussions for the Universist. (shrink)

When this article was first planned, writing was going to be exclusively about two things - the origin of life and human evolution. But it turned out to be out of the question for the author to restrict himself to these biological and anthropological topics. A proper understanding of them required answering questions like “What is the nature of the universe – the home of life – and how did it originate?”, “How can time travel be removed from fantasy and (...) science fiction, to be made scientific and practical?”, and “How can the proposed young age of genus Homo be made to actually be reasonable – when simply stating it would be solid ground for instant rejection and dismissal?” The result is that the article also talks about subjects like Artificial Intelligence, General Relativity, and cosmology. -/- From where did life originate? God? Evolution? Panspermia? If the tendency of humans and scientists to regard undiscovered science as pseudoscience can be overcome, Einstein gave another alternative to consider when he introduced General Relativity. Time isn’t linear – progressing in a straight line from past to present to future. That assumption ignores Relativity which states that space AND TIME are curved. Where did life and the genetic code come from? Can the answer build AI? -/- The first question can be answered by the section of this article titled SETI, Evolution, and Time which says life (possibly multicellular and intelligent) and the genetic code came from humans acquiring knowledge of these things over the centuries, then applying that knowledge – via terraforming, accumulation of raw materials like amino acids and nucleic acids, genetic engineering - to a time in the past when life didn’t exist. From that origin, life evolved through innumerable mutations and adaptations, with humans once again acquiring knowledge of it in cyclic (nonlinear) time. -/- The second question is answered by saying artificial intelligence (AI) as the product of life is only half of the equation. The other half refers to Relativity’s curved space-time and violation of the notion that time always travels from past to future. We have always lived in an artificially intelligent, non-probabilistic universe where everything in time and space is connected into one thing by quantum entanglement – making the brain and genes products of binary-digit activity or artificial intelligence (life is not merely dependent on biology’s “lock and key” mechanisms but also possesses AI). -/- The earliest documented representative of the genus Homo is Homo habilis, which evolved around 2.8 million years ago. Scientists used to believe there was a straight line from H. habilis to us, Homo sapiens. This article will use the “advanced” waves loved by Physics Nobel laureate Richard Feynman, view the history of science through the lens of Conic Sections applied to Relativity’s curved space-time, and incorporate the necessity of so-called imaginary time * – popularized by Prof. Stephen Hawking. While the evolutionary proposals are more in agreement with this early straight line than with modern theories, Albert Einstein’s General Relativity is used to transform the straight line into a curved line, ultimately concluding that Homo habilis (H. habilis) originated only (and unbelievably, as far as today’s science and technology is concerned) ~250,000 years ago. Other branches and dead ends of Homo – e.g. Neanderthals – are the result of mutations and adaptations, with the resultant modifications to anatomy and physiology. The surprisingly young age of H. habilis allows nearly 200,000 years for habilis, or one of its descendants, to reach Australia … if this country’s indigenous Aboriginal population did, as claimed, reach this “island continent” 60,000 years ago. -/- * The ultraviolet catastrophe, also called the Rayleigh–Jeans catastrophe, is a failure of classical physics to predict observed phenomena: it can be shown that a blackbody - a hypothetical perfect absorber and radiator of energy - would release an infinite amount of energy, contradicting the principles of conservation of energy and indicating that a new model for the behaviour of blackbodies was needed. At the start of the 20th century, physicist Max Planck derived the correct solution by making some strange (for the time) assumptions. In particular, Planck assumed that electromagnetic radiation can only be emitted or absorbed in discrete packets, called quanta. Albert Einstein postulated that Planck's quanta were real physical particles (what we now call photons), not just a mathematical fiction. From there, Einstein developed his explanation of the photoelectric effect (when quanta or photons of light shine on certain metals, electrons are released and can form an electric current). So it appears entirely possible that another supposed mathematical trickery (imaginary time and the y-axis of Wick rotation) will find practical application in the future. -/- The article includes mathematical references to cosmology (spoiler alert – you’ll read about things like Vector-Tensor-Scalar Geometry, topology, the “eternal present”, Einstein’s Unified Field, the inverse-square law, and there being no Big Bang and no multiverse - but there will also be no equations). -/- The other subheadings in this essay are – -/- NONLINEAR TIME AND ELECTRICAL ENGINEERING (about a 2009 electrical engineering experiment at America’s Yale University, and cosmic wormholes) -/- BITS AND TOPOLOGY (base-2 maths aka Binary digiTS, Mobius strips, and figure-8 Klein bottles) -/- WICK ROTATION, CAUSALITY, AND UNITING TIME (do past, present and future co-exist in an “eternal present”?) -/- DIGITAL BRAIN, DIGITAL UNIVERSE (if the brain and the universe are ultimately composed of binary digits, we'll someday be able to do the same things with the brain and universe that we now do with computers) -/- PROPOSAL: HUMAN AND ANIMAL INSTINCTS ARE THE RESULT OF THE UNIVERSE BEING UNIFIED BY BINARY DIGITS (AND TOPOLOGY) (If everything in the universe is ultimately composed of electronic BITS, then the universe must possess Artificial Intelligence - some prefer the term Cosmic Consciousness) -/- INFORMATION THEORY CONQUERS A RED GIANT (preserving Earth by keeping the Sun near today’s level of activity forever).

This paper models God and time in the framework of modern physics. God bridges and simultaneously exists in (1) a universe with infinite tenseless time and (2) a created parallel universe with tensed time and a point origin. The primary attributes of God are inexhaustible love, inexhaustible perception, and inexhaustible force. The model also incorporates modern physics theories that include relativity, the conservation of energy, quantum mechanics, and multiverse geometry. For example, creation out of nothing and divine intervention are (...) subject to physical processes and likewise nomological possibility. I will call this model semiclassical theism. (shrink)

Despite its enormous practical success, many physicists and philosophers alike agree that the quantum theory is full of contradictions and paradoxes which are difficult to solve consistently. Even after 90 years, the experts themselves still do not all agree what to make of it. The area of disagreement centers primarily around the problem of describing observations. Formally, the so-called quantum measurement problem can be defined as follows: the result of a measurement is a superposition of vectors, each representing the (...) quantity being observed as having one of its possible values. The question that has to be answered is: how this superposition can be reconciled with the fact that in practice we only observe one value. How is the measuring instrument prodded into making up its mind which value it has observed? Among some alternatives to resolve the above QM measurement problem, a very counterintuitive one was suggested by Hugh Everett in his 1955 Princeton dissertation, which was subsequently called the Many-Worlds Interpretation of QM (MWI). In this paper we will not discuss all possible scenarios to solve the measurement problem, but we will only shortly discuss Everett’s MWI, because it has led to heated debates on possibility of multiverses, beyond the Universe we live in. We also discuss two alternatives against MWI proposal: (a) the so-called scale symmetry theory, (b) the Maxwell-Dirac isomorphism. In last section, we also discuss shortly MWI hypothesis from philosophical perspective. (shrink)

As an application of his Material Theory of Induction, Norton (2018; manuscript) argues that the correct inductive logic for a fair infinite lottery, and also for evaluating eternal inflation multiverse models, is radically different from standard probability theory. This is due to a requirement of label independence. It follows, Norton argues, that finite additivity fails, and any two sets of outcomes with the same cardinality and co-cardinality have the same chance. This makes the logic useless for evaluating (...) multiverse models based on self-locating chances, so Norton claims that we should despair of such attempts. However, his negative results depend on a certain reification of chance, consisting in the treatment of inductive support as the value of a function, a value not itself affected by relabeling. Here we define a purely comparative infinite lottery logic, where there are no primitive chances but only a relation of ‘at most as likely’ and its derivatives. This logic satisfies both label independence and a comparative version of additivity as well as several other desirable properties, and it draws finer distinctions between events than Norton's. Consequently, it yields better advice about choosing between sets of lottery tickets than Norton's, but it does not appear to be any more helpful for evaluating multiverse models. Hence, the limitations of Norton's logic are not entirely due to the failure of additivity, nor to the fact that all infinite, co-infinite sets of outcomes have the same chance, but to a more fundamental problem: We have no well-motivated way of comparing disjoint countably infinite sets.

I examine what the mathematical theory of random structures can teach us about the probability of Plenitude, a thesis closely related to David Lewis's modal realism. Given some natural assumptions, Plenitude is reasonably probable a priori, but in principle it can be (and plausibly it has been) empirically disconfirmed—not by any general qualitative evidence, but rather by our de re evidence.

The Hyperuniverse Programme, introduced in Arrigoni and Friedman (2013), fosters the search for new set-theoretic axioms. In this paper, we present the procedure envisaged by the programme to find new axioms and the conceptual framework behind it. The procedure comes in several steps. Intrinsically motivated axioms are those statements which are suggested by the standard concept of set, i.e. the `maximal iterative concept', and the programme identi fies higher-order statements motivated by the maximal iterative concept. The satisfaction of these statements (...) (H-axioms) in countable transitive models, the collection of which constitutes the `hyperuniverse' (H), has remarkable 1st-order consequences, some of which we review in section 5. (shrink)

_The Metaphysics of Perfect Beings_ addresses the problems an Anselmian perfect being faces in contexts involving unlimited options. Recent advances in the theory of vagueness, the metaphysics of multiverses and hyperspace, the theory of dynamic or sequential choice, the logic of moral and rational dilemmas, and metaethical theory provide the resources to formulate the new challenges and the Anselmian responses with an unusual degree of precision. Almeida shows that the challenges arising in the unusual contexts involving unlimited (...) options sometimes produce metaphysical surprise. (shrink)

Recent work in the philosophy of religion has resurrected Leibniz’s idea that there is a best possible world, perhaps ours. In particular, Klaas Kraay’s [2010] construction of a theistic multiverse and Nevin Climenhaga’s [2018] argument from infinite value theory are novel defenses of a best possible world. I do not think that there is a best world, and show how both Kraay and Climenhaga may be resisted. First, I argue that Kraay’s construction of a theistic multiverse can (...) be resisted from plausible assumptions about set theory. Next, I argue against the value-theoretic assumptions that underlie Climenhaga’s argument and show how to give an infinite value theory where there is no best world. (shrink)

Some modern cosmological models predict the appearance of Boltzmann Brains: observers who randomly fluctuate out of a thermal bath rather than naturally evolving from a low-entropy Big Bang. A theory in which most observers are of the Boltzmann Brain type is generally thought to be unacceptable, although opinions differ. I argue that such theories are indeed unacceptable: the real problem is with fluctuations into observers who are locally identical to ordinary observers, and their existence cannot be swept under the (...) rug by a choice of probability distributions over observers. The issue is not that the existence of such observers is ruled out by data, but that the theories that predict them are cognitively unstable: they cannot simultaneously be true and justifiably believed.

Discussion of new axioms for set theory has often focused on conceptions of maximality, and how these might relate to the iterative conception of set. This paper provides critical appraisal of how certain maximality axioms behave on different conceptions of ontology concerning the iterative conception. In particular, we argue that forms of multiversism (the view that any universe of a certain kind can be extended) and actualism (the view that there are universes that cannot be extended in particular ways) (...) face complementary problems. The latter view is unable to use maximality axioms that make use of extensions, where the former has to contend with the existence of extensions violating maximality axioms. An analysis of two kinds of multiversism, a Zermelian form and Skolemite form, leads to the conclusion that the kind of maximality captured by an axiom differs substantially according to background ontology.

The Concept of Human Spirit After Death in a Type III Civilization -/- Introduction -/- The idea of life after death has long been a central concern of philosophy, religion, and science. In today’s world, discussions about the human spirit often remain in the realm of faith and speculation. However, in a Type III civilization—one that has harnessed the energy of an entire galaxy—such questions might no longer be mysterious. With access to advanced technology, deep understanding of consciousness, and mastery (...) over the laws of physics, a Type III civilization could fundamentally transform our understanding of the human spirit after death. Would death still exist in such a civilization, or would it become a choice? Could consciousness continue beyond physical existence? This essay explores how a hyper-advanced society might handle the concept of the human spirit in ways that align with both scientific progress and the universal law of balance in nature. -/- The Scientific Resurrection of Consciousness -/- A Type III civilization would likely possess a complete understanding of consciousness, allowing them to preserve, reconstruct, or even transfer human awareness beyond physical death. If consciousness is a pattern of information, then it could be digitally stored, uploaded, or reinserted into new biological or artificial forms. This would mean that death, as we know it, could be overcome through advanced neuroscience, computation, and physics. -/- For example, through brain scanning and neural mapping, a civilization of this level might extract and preserve an individual’s entire consciousness, including memories, thoughts, and personality. This preserved consciousness could then be placed into a synthetic body, a digital simulation, or even a fully biological clone, allowing individuals to continue their existence indefinitely. This would make the afterlife a technological reality rather than a spiritual mystery. -/- However, if the universal law of balance in nature dictates that all systems must have limits to maintain stability, then a Type III civilization may choose not to completely eliminate death. Instead, they may regulate immortality, ensuring that consciousness does not infinitely persist without purpose. -/- Quantum Consciousness and Energy-Based Spirits -/- Some modern theories, such as quantum consciousness, suggest that the human mind is not simply a product of brain activity but also interacts with quantum fields. If this is true, then a Type III civilization could manipulate these fields, allowing consciousness to exist beyond the body as an energy-based form. -/- In this model, the “spirit” would not be a supernatural entity but a complex quantum state that continues to exist in a higher-dimensional structure of the universe. The civilization could develop methods to interact with and even re-integrate these energy-based consciousnesses into new physical forms or other dimensions of existence. -/- This idea aligns with the principle that all systems must follow natural balance—even if consciousness exists after death, it would not violate the fundamental laws of physics but instead be an integrated part of the universal structure. -/- Multiverse and Simulation Theories: Death as a Transition -/- A Type III civilization might discover that reality itself is a simulation or part of a multiverse. If true, death could be nothing more than a transfer of consciousness to another layer of reality. Rather than an end, death could be a shift to an alternative existence. -/- In this case, the civilization might have the ability to manipulate these transitions, offering individuals the choice of: -/- 1. Returning to a new life in a simulated or real universe -/- 2. Existing as a digital being within an advanced AI system -/- 3. Transcending to a higher-dimensional existence that aligns with natural laws -/- If the universe is a vast, interconnected system, then death could be seen as a necessary cycle that maintains balance, preventing stagnation and allowing renewal at cosmic scales. A Type III civilization might control and regulate these cycles to ensure harmony. -/- Spiritual Evolution and Cosmic Integration -/- Beyond scientific solutions, a Type III civilization may evolve to understand that consciousness naturally integrates with the cosmos after death. If the universal law of balance applies at all levels, then consciousness would follow this principle, transitioning in a way that contributes to the greater equilibrium of the galaxy. -/- Instead of preventing death entirely, such a civilization might develop a controlled process of spiritual evolution, where individuals choose their next phase of existence in alignment with universal balance. This could include: -/- Becoming part of the galactic consciousness, merging with a larger intelligence. -/- Returning to physical existence in another form to maintain equilibrium. -/- Moving into higher-dimensional realities where new experiences unfold. -/- This approach ensures that consciousness does not simply persist indefinitely in a stagnant form but contributes to the evolution of the universe itself. -/- Would a Type III Civilization Eliminate Death? -/- One of the most profound questions is whether a Type III civilization would abolish death entirely. While they could likely eliminate involuntary death, natural balance may still require cycles of renewal and transformation. -/- If death serves a functional role in maintaining cosmic order, then a highly advanced society would respect this law rather than override it. They might create controlled transitions where beings evolve beyond their previous states without disrupting universal harmony. -/- A civilization that aligns with your universal formula—where decision-making follows the natural law of balance—would recognize that immortality without purpose leads to instability. Instead of avoiding death altogether, they might ensure that life, death, and transformation exist as part of a greater cosmic design. -/- Conclusion -/- In a Type III civilization, the concept of the human spirit after death would no longer be a mystery. Whether through scientific resurrection, quantum consciousness, multiversal transitions, or spiritual evolution, such a society would fundamentally reshape how death is experienced. However, if the universal law of balance is truly fundamental, then death might still serve a necessary role in maintaining cosmic equilibrium. Rather than erasing death, a Type III civilization may redefine it as a transition into new forms of existence, ensuring that consciousness remains in harmony with the universe. -/- . (shrink)

Historically, philosophers who thought our world unsurpassable, like Leibniz, thought it the uniquely best of all possible worlds. But recent developments in value theory and philosophy of religion make clear that our world could be unsurpassable, but not uniquely best—because other worlds are still as good as or incomparable with it. In particular, the world may contain infinities that result in incomparability with many other worlds. This chapter advances the recent philosophical debate over whether it is tenable to hold (...) that our world is unsurpassable, given that it may contain an infinite number of people with lives that go infinitely well. I argue that while recent innovations in formal axiology offer prospects for comparing many worlds with these kinds of infinities, many infinite worlds are genuinely incomparable with each other. Consequently, whether there is another world better than our own ends up turning on substantive metaphysical and normative questions: metaphysical questions about personal identity across possible worlds, and normative questions about what makes for a valuable life.
