The article explains how the primordial singularity can be understood as a cause having brought the Universe into empirical existence. It also addresses the nonempirical nature of such a cause.

This note briefly discusses the observation of elapsed time in a flat universe while exploring the argument of past-eternal time versus emergent time in cosmology. A flat universe with an incomplete past forever has a finite age. Despite an infinite number of Planck time coordinates independent of phenomena and endless expansion, a flat universe never develops an age with an infinite number of Planck times. This observation indicates the impossibility of infinitely elapsed time in the future or past, which limits (...) acceptable scientific models of cosmology. (shrink)

Introduction to alternative ontology of mind and physics based on the multi-dimensional model of A Geometric Theory of the Universe (Holster).

The mathematical constructions, physical structure and manifestations of physical time are reviewed. The nature of insight and mathematics used to understand and deal with physical time associated with classical, quantum and cosmic processes is contemplated together with a comprehensive understanding of classical time. Scalar time (explicit time or quantitative time), vector time (implicit time or qualitative time), biological time, time of and in conscious awareness are discussed. The mathematical understanding of time in special and general theories of relativity is critically (...) analyzed. The independent nature of classical, quantum and cosmic physical times from one another, and the manifestations of respective physical happenings, distinct from universal time, are highlighted. The role of a universal time related or unrelated to origin, being etc., of universe or cosmos as common thread in all happenings is reviewed. The missing of time is identified and concept of absence of time is put forward. The complex nature of time and the real and imaginary dimensions of physical time are also elaborately discussed together with human time- consciousness as past, present and future. (shrink)

The current cosmological models are built based on general relativity. The solutions of the specific equations, Friedmann-Lemaître-Robertson-Walker, allow to model the evolution of the universe starting from the Big Bang. Some of the parameters of the universe have been established by observations. Based on these, and other observational data, the models can be tested. Predictions include the initial abundance of chemical elements formed in a period of nucleosynthesis during the Big Bang period, the subsequent structure of the universe, cosmic background (...) radiation, and so on.

Modelele cosmologice actuale sunt construite pe baza relativității generale. Soluțiile ecuațiilor specifice, Friedmann-Lemaître-Robertson-Walker permit modelarea evoluției universului pornind de la Big Bang. O parte din parametrii universului au fost stabiliți prin observații. Pe baza acestora, și altor date observaționale, se pot testa modelele. Predicțiile includ abundența inițială de elemente chimice formate într-o perioadă de nucleosinteză în perioada Big Bang, structura ulterioară a universului, radiația cosmică de fond, etc. DOI: 10.13140/RG.2.2.22204.59525.

This report offers a modern perspective on the problem of negative energy, based on a reexamination of the concept of time direction as it arises in a classical and quantum-mechanical context. From this analysis emerges an improved understanding of the general-relativistic stress-energy of matter as being a manifestation of local variations in the energy density of zero-point vacuum fluctuations. Based on those developments, a set of axioms is proposed from which are derived generalized gravitational field equations which actually constitute a (...) simplification of relativity theory in the presence of negative-energy matter and a non-zero cosmological constant. Important clarifications are also achieved regarding the nature of the binary degrees of freedom of matter in the final stages of a gravitational collapse. Those results are then applied to provide original solutions to several long-standing problems in cosmology, including the problem of the nature of dark matter and dark energy, that of the origin of thermodynamic time asymmetry, and several other issues traditionally approached using inflation theory. Finally, we draw on those developments to provide significant new insights into the foundations of quantum theory, regarding, in particular, the problem of quantum non-locality, that of the emergence of time in quantum cosmology, as well as the question of the persistence of quasiclassicality following decoherence.

Penrose's conformal cyclic cosmology describes the cosmos as a collection of successive universes, the so-called aeons. The beginning and ending of our universe are directly connected to two other, anterior and posterior, universes. Penrose considers but rules out a different interpretation of conformal cyclic cosmology: that the beginning of our universe is connected to its own end in a cosmic loop. The paper argues that the view, aeon monism, should be regarded as a natural interpretation of conformal cyclic cosmology and (...) discusses its implications for the concept of eternal return in light of the most popular metaphysics of time.

Dark matter in astrophysics offers a rare treat for philosophers of science. When they look at the contemporary science of dark matter, they see reports of a widely accepted theoretical posit indispensable to our best theories and models but without an accepted experimental confirmation of its existence. Nearly all astrophysicists and cosmologists believe that dark matter exists and makes up approximately a quarter of the mass-energy content of the universe. However, they seem to know almost nothing about its nature, cannot (...) directly observe it, and have been unable to detect the products of any interactions with any of the candidate dark matter particles. This project addresses the apparent tension between the impressive knowledge taken to have been obtained in contemporary sciences of the cosmos and the methodological and theoretical limitations in obtaining such knowledge. To do so, this dissertation investigates the ways in which astronomers and astrophysicists are making progress by looking more closely at their experimental practices and actual theoretical commitments. More specifically, the goal is to determine how this bears on longstanding philosophical questions of scientific realism and the nature of scientific experimentation. Ultimately, I argue that astronomers do conduct traditional, interventionist experiments and that we can be realists about dark matter. These two views offer a way of thinking differently about how scientists can and do obtain knowledge about inaccessible and unobservable targets systems. -/- . (shrink)

Não é pensando que criamos mundos. É compreendendo o mundo que aprendemos a pensar. Cosmovisão é um termo que deve significar um conjunto de fundamentos dos quais emerge uma compreensão sistêmica do Universo, seus componentes como a vida, o mundo em que vivemos, a natureza, o fenômeno humano e suas relações. Trata-se, portanto, de um campo da filosofia analítica alimentado pelas ciências, cujo objetivo é esse conhecimento agregado e epistemologicamente sustentável sobre tudo o que somos e contemos, que nos cerca (...) e que nos relaciona de alguma forma. É algo tão antigo quanto o pensamento humano e, além de utilizar elementos da cosmologia científica, engloba tudo na filosofia e na ciência que se refere ao universo e à vida. Uma cosmovisão não é um conjunto de ideias, hipóteses e suposições, mas um sistema baseado em observação, análise, evidência e demonstração. Nenhuma cosmovisão pretende definir, estabelecer, propor, mas apenas compreender, analisar e interpretar. Cada um de nós constrói e transporta sua cosmovisão ao longo da vida, sem estabelecer formas, como pano de fundo para nosso pensamento e comportamento. Linguisticamente, o termo “cosmovisão” derivaria do alemão, equivalente ao conceito de “ Weltanschauung”, usado por vários filósofos. No entanto, essa relação linguística não é aplicável porque contraria o que propomos como cosmovisão. Esta palavra alemã refere-se a uma visão pré-lógica ou proto-experimental da realidade, com um contexto intuitivo e longe de um conhecimento crítico ainda inexistente no momento da sua formulação. Sem dúvida, as cosmovisões , no sentido em que as entendemos, abrigam e utilizam esses elementos protoexperimentais ou pré-lógicos que incluem a história, o inconsciente coletivo e todos os arquétipos que carregamos. No entanto, no conceito que aqui aplicamos, a cosmovisão vai muito além desse conteúdo, primeiro por submetê-lo constantemente ao pensamento crítico presente e, finalmente, por tornar a experiência analítica (e não o próprio pensamento ou intuição) seu universo real. António Lopes expõe a amplitude deste conteúdo: -/- “Cosmovisões não são o produto do pensamento. Não nascem do simples desejo de saber. A apreensão da realidade é um momento importante em sua configuração, mas, no entanto, é apenas um. Vem da conduta vital, da experiência da vida, da estrutura de nossa totalidade psíquica. A elevação da vida à consciência no conhecimento da realidade, na valorização da vida e na realidade volitiva é o trabalho lento e árduo que a humanidade tem feito no desenvolvimento das concepções de vida. (W. Dilthey, 1992 [1911]: 120)” Neste trabalho, buscamos traçar uma cosmovisão baseada nas realidades que a ciência oferece hoje. Não nos propomos, em nenhum momento, a fazer ciência ou teorizar a filosofia, mas sempre buscaremos ser apoiados por elas ou, pelo menos, protegidos por elas das distorções cognitivas que costumamos carregar.

Abstract: In a 1999 book entitled 'The Cosmic Sphere', the author proposed an unconventional model of the Universe intended to solve conceptual and empirical problems facing the Big Bang theory. The author has since had second thoughts, however, and has concluded that his proposed Cosmic Sphere Model (CSM) of the Universe is flawed and cannot be accurate. In this article, the author provides an overview of 'The Cosmic Sphere' and CSM, points out the errors of both, analyzes the implications of (...) the errors, and closes with a few words about a future philosophical publication on cosmology.

Cosmologists take the $\Lambda$CDM model to be a permanent contribution to our knowledge of the universe, based on the success of precision cosmology. Consistent, independent determinations of the parameters in this model encourage physicists to take it seriously. This stance incurs an obligation to resolve any discrepancies by reanalyzing measurements or adding further complexity. Recent observations in cosmology indicate a tension between “local” and “global” determinations of the Hubble constant. Here I argue that this tension illustrates one of the benefits (...) of taking the model seriously and consider the challenges to making a case for the permanence of $\Lambda$CDM. (shrink)

Physics Overwritten in a new perspective: “Epistemologically Different Worlds” (Einsteins’ relativities without “spacetime”, quantum me-chanics, pre-Big Bang, Big Bangs and “inflation”, dark mat-ter and dark energy, the superstring theory, and Bohr’s com-plementarity) -/- .

Consider an infinite series whose items are each explained by their immediate successor. Does such an infinite explanation explain the whole series or does it leave something to be explained? Hume arguably claimed that it does fully explain the whole series. Leibniz, however, designed a very telling objection against this claim, an objection involving an infinite series of book copies. In this paper, I argue that the Humean claim can, in certain cases, be saved from the Leibnizian “infinite book copies” (...) objection, and that this provides an interesting way to defuse some cosmological arguments for the existence of God and to give a non-theistic but complete explanation of the Universe. In the course of my argumentation, I also show that circular explanations can be “self-explanatory” as well: explaining two items by each other can explain the couple of items tout court. (shrink)

The paper addresses a question concerning George Ellis’s theory of top-down causation by considering a challenge to the “level-picture of nature” which he employs as a foundational element in his theory. According to the level-picture, nature is ordered by distinct and finitely many levels, each characterised by its own types of entities, relations, laws and principles of behavior, and causal relations to their respective neighbouring top- and bottom-level. The branching hierarchy that results from this picture enables Ellis to build his (...) model of modular hierarchical structure for complexity, his account of same-level, bottom-up and top-down causation, of emergence, equivalence-classes and multiple realisability. The three main arguments for the level-picture in Ellis’s works are reconstructed and shown to face serious problems. Finally, the paper presents a possible solution to this challenge by introducing a reformulation of certain fundamental points of Ellis’s theory that does without the level-picture of nature. This allows us to preserve all of his central claims about the model of complexity, the three types of causation, emergence, equivalence-classes and multiple realisability. Any problems pertaining to the level-picture can be remedied in the context of Ellis’s theory of top-down causation. (shrink)

From the beginning of time, humans believed they were the center of the universe. Such important beings could be nowhere else than at the very epicenter of existence, with all the other things revolving around them. Was this an arrogant position? Only time will tell. What is certain is that as some people were so certain of their significance, aeons later some other people became too confident in their unimportance. In such a context, the Earth quickly lost its privileged position (...) at the center of the universe and along with this, the ideas of absolute motion and time became unbearable for the modern intellect, which saw nothing but relativeness in everything. After years of accepting the ideas of relativity at face value without doubting them, scientists are now mature enough to start questioning everything as any true scientist would do, including their own basic assumptions. And one would be surprised to see that the basic assumptions of today’s science in physics (and cosmology alike) are based on philosophically dogmatic beliefs that humans are nothing more than insignificant specks of dust. These specks cannot be in any privileged position in the cosmos, nor can their frames of reference. These specks cannot be living on a planet that is not moving while everything else is. There can be no hint of our importance whatsoever. Hence, the Copernican principle that has poisoned scientific thinking for aeons now. When one analyzes the evidence provided by science to support the idea of relativity though, he would see that the same evidence can more easily and simply fit into a model where the Earth stands still. Yet, scientists preferred to revamp all physics by introducing the totally unintuitive ides of relativity – including the absolute limit of the speed of light – than even admitting the possibility of humans having any notion of central position in the cosmos. True scientists though should examine all possible explanations, including those that do not fit their beliefs. To the dismay of so many modern scientists who blindly believe the validity of the theory of relativity at face value, the movement towards a true and honest post-modern science where all assumptions are questioned, necessarily passes through a place where the Earth we live in stands still. Non-relativistic explanations of the Michelson Morley experiment, related to a motionless Earth or to ether, are viable alternatives that deserve their place in modern scientific thought. (shrink)

I investigate the role of stability in cosmology through two episodes from the recent history of cosmology: Einstein’s static universe and Eddington’s demonstration of its instability, and the flatness problem of the hot big bang model and its claimed solution by inflationary theory. These episodes illustrate differing reactions to instability in cosmological models, both positive ones and negative ones. To provide some context to these reactions, I also situate them in relation to perspectives on stability from dynamical systems theory and (...) its epistemology. This reveals, for example, an insistence on stability as an extreme position in relation to the spectrum of physical systems which exhibit degrees of stability and fragility, one which has a pragmatic rationale, but not any deeper one.

In this work I propose a theory of evolution as a process of unfolding. This theory is based on four logically concatenated principles. The principle of evolutionary order establishes that the more complex cannot be generated from the simpler. The principle of origin establishes that there must be a maximum complexity that originates the others by logical deduction. Finally, the principle of unfolding and the principle of actualization guarantee the development of the evolutionary process from the simplest to the most (...) complex. These logical principles determine the existence of a virtual ideological matrix that contains the sequence of the preformed and folded morphogenetic fields. In this manner, the evolutionary process consists of the sequential unfolding and actualization of these fields, which is motorized by a process of teleologization carried out by the opening consciousness of the forms included in the fields of the ideological matrix. This theory leads to a radical change of perspective regarding the materialist worldview, and places life at the center of the evolutionary process as an activity carried out by a consciousness that seeks to fulfill a purpose by actualizing its own potentialities.

Has science already answered the fundamental questions about the concepts of Life, Cosmos and Evolution? Has science not relegated these fundamental questions by following up on more immediate, “useful” and practical endeavors that ultimately ensure that the wheel of capitalism keeps spinning in its frantic search for material and economic progress? There is something terribly wrong with the current theory of evolution, understood as the Darwinian theory with its successive versions and extensions. The concept of natural selection, the cornerstone of (...) Darwinism, is logically inconsistent. This has been demonstrated in some of my latest academic publications. The entire conceptual framework of Darwinism is inadequate. Organisms do not compete with each other for the survival of the fittest. The fundamental relationship in Nature is not competition or confrontation, but interconnectivity, complementarity, and relational meaningfulness. A new theory of evolution is necessary to explain how it is possible that organisms as simple as bacteria, protozoa and diatoms could have generated organisms as complex as primates, and among them, the human being, a being capable of feeling and thinking, of suffering and enjoying, a being capable of having ideals and purposes. A theory that explains how it is possible that this being so complex, rich, and to some extent still unknown, has emerged from a single cell, an egg-cell, lacking all the capacities, riches and depths of human existence. Such a theory already exists. (shrink)

Die zentralen Fragestellungen bezüglich der wahren Beschaffenheit des Universums betreffen Folgendes: seinen Ursprung, seine Entstehung, die Existenz und Kontingenz seiner Gesetze, seine Intentionalität, Fassbarkeit, Transzendenz und die Anwendung erster Grundsätze, die diesen Phänomenen zugrunde liegen. Häufig sind die entsprechenden Untersuchungen jedoch belastet von (1) einer „semantischen Transmutation“ von Konzepten und Begriffen zwischen und innerhalb von drei allgemeinen Wissensfeldem - dem physikalischen, philosophischen und theologischen - sowie von (2) den Einschränkungen der anfänglichen Leitgedanken des Betrachters, die oft von skeptischen Annahmen geleitet (...) werden und uns hindern, die Möglichkeiten zu erforschen, die unserer ursprünglichen Einstellung widersprechen. Obwohl ich mich im Laufe meiner Untersuchung mit diesen Problemen beschäftigen werde, ist das Hauptergebnis dieser Studie ein Erklärungsvorschlag zum Phänomen des „Nichts“ und insbesondere seines Verhältnisses zum Universum oder zu Gott. Das Nichts ist eine der Hauptquellen argumentativer Abhandlungen für und gegen die Existenz und Anerkennung Gottes auf Grundlage von Argumenten bezüglich des Ursprungs unseres Universums. Der Erklärungsvorschlag soll als Anleitung zu einer Konstruktion von Gegenargumenten dienen, die vielen der Annahmen widersprechen, die einer Vielzahl an Autoren als „kosmologische“, „logische“, „ontologische“, „physikotheologische“ und ähnliche Beweissysteme für oder gegen die Existenz Gottes dienen. Hauptsächlich werden die Problemstellungen des Ursprungs und der Schöpfung unseres Universums diskutiert. Im Zuge dessen beschäftige ich mich jedoch auch mit den anderen genannten Fragen. Der Hauptfokus liegt auf der Schwierigkeit, das Phänomen des Nichts in kosmologische Auseinandersetzungen über Ursache und Ursprung des Universums einzubeziehen. Dies wird in drei Untersuchungen betrachtet. Die erste Untersuchung konzentriert sich auf die Begriffe des Seins, des Nichtseins, des Absoluten und des Nichts, da diese üblicherweise bei der Erforschung des Universums und des Wesens Gottes verwendet werden. Die Untersuchung entwickelt sich dann in Form eines dialektischen Vergleichs ausgewählter Philosophen weiter, die sich mit dem gewählten Thema befasst haben und endet in einer übergreifenden Synthese, in der ich versuche, die Zusammenhänge zu klären und den Begriff des Einzig-Absoluten für die zweite und dritte Untersuchung zu definieren.

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.

Computer simulations of the formation and evolution of large-scale structure in the universe are integral to the enterprise of modern cosmology. Establishing the reliability of these simulations has been extremely challenging, primarily because of epistemic opacity. In this setting, robustness analysis defined by requiring converging outputs from a diverse ensemble of simulations is insufficient to determine simulation validity. We propose an alternative path of structured code validation that applies eliminative reasoning to isolate and reduce possible sources of error, a potential (...) path that is already being explored by some cosmologists.

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)

In a world awash in statistical patterns, should we conclude that the universe’s evolution or genesis is somehow subject to chance? I draw attention to alternatives that must be acknowledged if we are to have an adequate assessment of what chance the universe might have had.

We explore how one might respond emotionally to the eternal recurrence. Zarathustra himself serves as our central case study. First we clarify the idea of eternal recurrence and its role in Nietzsche’s philosophy, explaining why the eternal recurrence has the emotional consequences Nietzsche describes when he first introduces the idea in The Gay Science. Then we describe Zarathustra’s emotional journey from horror at the eternal recurrence to loving it, in the sections from “On Great Events” to “The Seven Seals, or: (...) The Yes and Amen Song.”.

I have read many recent discussions of the limits of computation and the universe as computer, hoping to find some comments on the amazing work of polymath physicist and decision theorist David Wolpert but have not found a single citation and so I present this very brief summary. Wolpert proved some stunning impossibility or incompleteness theorems (1992 to 2008-see arxiv dot org) on the limits to inference (computation) that are so general they are independent of the device doing the computation, (...) and even independent of the laws of physics, so they apply across computers, physics, and human behavior. They make use of Cantor's diagonalization, the liar paradox and worldlines to provide what may be the ultimate theorem in Turing Machine Theory, and seemingly provide insights into impossibility, incompleteness, the limits of computation, and the universe as computer, in all possible universes and all beings or mechanisms, generating, among other things, a non- quantum mechanical uncertainty principle and a proof of monotheism. There are obvious connections to the classic work of Chaitin, Solomonoff, Komolgarov and Wittgenstein and to the notion that no program (and thus no device) can generate a sequence (or device) with greater complexity than it possesses. One might say this body of work implies atheism since there cannot be any entity more complex than the physical universe and from the Wittgensteinian viewpoint, ‘more complex’ is meaningless (has no conditions of satisfaction, i.e., truth-maker or test). Even a ‘God’ (i.e., a ‘device’with limitless time/space and energy) cannot determine whether a given ‘number’ is ‘random’, nor find a certain way to show that a given ‘formula’, ‘theorem’ or ‘sentence’ or ‘device’ (all these being complex language games) is part of a particular ‘system’. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

The letter is suggesting that dark energy, dark matter and universal expansion are intimately related.

This essay presents a review on Brian Swimme’s 3-DVD set of lecture series in the interdisciplinary field of philosophy, cosmology and consciousness. In the eleven 45-minute episodes of a systematic 9-hour immersive program, a set of 12 intercorrelated cosmological powers is proposed on the basis of modern scientific theory. A positive and life-affirming vision of human potential is attained together with a new level of ecological responsibility and relatedness. The interwoven cosmological paradigm compromises with two ancient eastern wisdoms.

I discuss the formal implementation, interpretation, and justification of likelihood attributions in cosmology. I show that likelihood arguments in cosmology suffer from significant conceptual and formal problems that undermine their applicability in this context.

First recorded in the 14th century, the analogy of spit-roast meat argues that expecting the Sun to rotate around a strictly immobile Earth would be just as ludicrous as trying to move the fire around the roasting meat. On the contrary, it should be the Earth that spins upon itself in order to glean, from all possible angles, all the benefits of the Sun, just as it is the meat’s responsibility to turn on the spit before the motionless fire for (...) it to be perfectly cooked on all sides. Aimed at demonstrating, in geocentricism, the plausibility of the rotation of the Earth and, in heliocentrism, at supporting the physical reality of this terrestrial rotation, nowadays this analogy barely elicits more than an amused, or even condescending, smile. However, its continued long-term existence and its frequency of use — from the 14th to the 19th century, we found it mentioned by no less than 45 different authors — incited us to finally pay attention to it. We then noticed that beyond its explicitly cosmological scope, it raises, in its own way, the question of the purpose of the natural world: had the latter been conceived based upon humankind, then it is normal, despite what this analogy advocates, that the Sun is at the service of something more important than itself by rotating, to the profit of humankind, around the Earth; conversely, since such an infringement of the rule of common sense, as illustrated by this analogy, can neither be justified nor tolerated, it is up to the Earth to move around the Sun. Tracing the vicissitudes of this analogy, over 6 centuries, is thus not only about reconstructing the largely forgotten history of a presently obsolete analogy, but also about discovering the deeper meaning, henceforth incomprehensible, behind it. In describing how this meaning became progressively lost, one can finally pro­vide an understanding of why, in the present day, we are no longer capable of more than an amused smile when happening upon it!

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.

Several physicists, among them Hawking, Page, Coule, and Carroll, have argued against the probabilistic intuitions underlying fine-tuning arguments in cosmology and instead propose that the canonical measure on the phase space of Friedman-Robertson-Walker space-times should be used to evaluate fine-tuning. They claim that flat space-times in this set are actually typical on this natural measure and that therefore the flatness problem is illusory. I argue that they misinterpret typicality in this phase space and, moreover, that no conclusion can be drawn (...) at all about the flatness problem by using the canonical measure alone. (shrink)

I develop two problems, which I call the problem of divine location and the problem of divine age, to challenge the theist belief that God created the universe. The problem of divine location holds that it is not clear where God existed before he created the universe. The problem of divine age holds that it is not clear how old God was when he created the universe. I explore several theist responses to these two problems, and argue that all of (...) them are problematic under the existing conceptions of space and time in physics. The philosophical magnitudes of these two problems are equal to that of the problem of evil. (shrink)

Scientific philosophy is that which is informed by science. It uses exact tools such as logic and mathematics and provides a framework for scientific activity to solve more general questions about nature, the language we use to describe it, and the knowledge we obtain thanks to it. Many of the scientific philosophy theories can be proven and evaluated using scientific evidence. In this paper, I focus on showing how several classical philosophy topics, such as the nature of space and time (...) or the dimensionality of the future, can be addressed philosophically using the tools from current astrophysics research and, in particular, from the study of black holes and gravitational waves.

Kosmos und Subjektivität – dieses Begriffspaar stellt sogleich einen Antagonismus vor, denn Subjektivität konstituiert sich alleine im irreduziblen Bruch mit der kosmischen Einheit.

Plausible assumptions from Cosmology and Statistical Mechanics entail that it is overwhelmingly likely that there will be exact duplicates of us in the distant future long after our deaths.

This is one of the best popular cosmology books ever written and Guth is now (2016) a top physics Professor at MIT. He tells the extremely complex story of inflation and related areas of particle physics in such an absorbing style that it reads like a detective novel-in fact, it is a detective novel-how he and others found out how the universe started! The interweaving of his personal story and that of many colleagues along with their photos and many wonderfully (...) clear diagrams allows just the right amount of relaxation from the intensity of the physics. In places the style reminds one of Watson´s famous book ``The Double Helix``. He tells how his work on magnetic monopoles and spontaneous symmetry breaking led to the discovery of the inflationary theory of the very early universe (ca. 10 to minus 35 seconds!). -/- Along the way you will learn many gems that should stay with you a long time such as: the observed universe(e.g., everything the Hubble telescope etc. can see out to ca. 15 billion light years when the universe began) is likely just a vanishingly tiny part of the entire inhomogeneous universe which is about 10 to the 23rd times larger; the big bang probably took place simultaneously and homogeneously in our observed universe; there probably have been and will continue to be an infinite number of big bangs in an infinite number of universes for an infinite time; when a bang happens, everything(space, time, all the elements) from the previous universe are destroyed; the stretching of space can happen at speeds much greater than the speed of light; our entire observed universe lies in a single bubble out of an endless number so there may be trillions of trillions just in our own entire(pocket) universe(and there may be an endless number of such); none of these infinite number of universes interact-i.e., we can never find out anything about the others; each universe started with its own big bang and will eventually collapse to create a new big bang; all this implies that the whole universe is fractal in nature and thus infinitely regresses to ever more universes(which can lead one to thinking of it as a giant hologram); disagreements between the endless(hundreds at least) variations of inflation are sometimes due to lack of awareness that different definitions of time are being used; some theories suggest that there was a first big bang but we can never find out what happened before it; nevertheless it appears increasingly plausible that there was no beginning but rather an eternal cycle of the destruction and creation, each being the beginning of spacetime for that universe; to start a universe you need about 25g of matter in a 10 to minus 26cm diameter sphere with a false vacuum and a singularity(white hole). -/- He deliberately spends little time on the endless variants of inflation such as chaotic, expanded and supernatural inflation or on dark matter´, supersymmetry and string theory, though they were well known at the time as you can find by reading other books such as Michio Kaku´s `Hyperspace` (see my review) and countless others. Of course much has happened since this book appeared but it still serves as an excellent background volume so cheap now it’s free for the cost of mailing. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

Dark matter and dark energy. Two notions that have troubled cosmologists for a long time. Why? Because they don’t have a “satisfactory” definition, and nobody can identify the “matter” or “forces” that govern them. Currently, we can only deduce the existence of these two notions from the strange movement of the galaxies and the manner they move away from one another, with increasing speed. However, these are not the only mysteries that cosmology cannot yet explain. What happened before the Big (...) Bang? Is the universe still expanding (cosmic inflation)? What is the relation between the theory of relativity and the laws of quantum mechanics? What if the answers to all these questions were far more accessible than researchers thought? What if the real “culprit” for their absence was in fact the framework used by cosmologists, a framework that involves the existence of space and time? With the help of the Epistemologically Different Worlds paradigm, Gabriel and Mihai Vacariu aim to offer an answer to all these questions and many others. -/- Content -/- Chapter 1 Epistemologically different worlds Chapter 2 Space and time cannot even exist! 2.1 Leibniz versus Newton 2.2 Space and time, just illusions of human mind 2.3 Spacetime, Einstein’s special theory of relativity, nothing and EDWs Chapter 3 Big Bang, inflation and gravitational waves 3.1 Big Bang and what was immediately after Big Bang: gravitational waves and inflation? 3.2 The results of BICEP2 about Big Bang, gravitational waves and inflation Chapter 4 Dark matter and dark energy 4.1 General information about dark matter and dark energy 4.2 “Haloes”, “structures”, and the “flat universe” 4.3 Does any relationship between dark matter and dark energy exist? 4.4 Do “interactions” of dark particles exist? 4.5 Other problems related to dark matter and dark energy 4.6 The Martian, dark matter and dark energy Chapter 5 Grand Unified Theory and Theory of Everything, the impossible relationship between quantum mechanics and Einstein’s theory of relativity 5.1 Einstein’s theory of relativity and quantum mechanics 5.2 GUT or TOE?

Inflationary cosmology has been widely accepted due to its successful predictions: for a “generic” initial state, inflation produces a homogeneous, flat, bubble with an appropriate spectrum of density perturbations. However, the discovery that inflation is “generically eternal,” leading to a vast multiverse of inflationary bubbles with different low-energy physics, threatens to undermine this account. There is a “predictability crisis” in eternal inflation, because extracting predictions apparently requires a well-defined measure over the multiverse. This has led to discussions of anthropic predictions (...) based on a measure over the multiverse, and an assumption that we are typical observers. I will give a pessimistic assessment of attempts to make predictions in this sense, emphasizing in particular problems that arise even if a unique measure can be found. (shrink)

This volume is the first systematic presentation of the work of Albert Einstein, comprising fourteen essays by leading historians and philosophers of science that introduce readers to his work. Following an introduction that places Einstein's work in the context of his life and times, the book opens with essays on the papers of Einstein's 'miracle year', 1905, covering Brownian motion, light quanta, and special relativity, as well as his contributions to early quantum theory and the opposition to his light quantum (...) hypothesis. Further essays relate Einstein's path to the general theory of relativity (1915) and the beginnings of two fields it spawned, relativistic cosmology and gravitational waves. Essays on Einstein's later years examine his unified field theory program and his critique of quantum mechanics. The closing essays explore the relation between Einstein's work and twentieth-century philosophy, as well as his political writings. (shrink)

Nel corso della seconda metà del XX secolo si è progressivamente svilppata ed affermata una cosmologia “standard”: vedremo in che cosa consiste e come si è costituita. Vedremo anche quali sono i suoi limiti e quali nuove teorie si candidano per superarli. Vorrei comunque chiarire subito che la cosmologia standard, per quanto possano sembrare sorprendenti i suoi risultati (qualche specialista parla di preposterous universe, ovvero di un assurdo universo), si fonda su esperimenti ed osservazioni, ed avrebbe potuto essere falsificata tante (...) volte: ciò non è finora accaduto. Al cuore della cosmologia standard abbiamo quella che viene chiamata “teoria del Big Bang” la quale, offrendo una descrizione quantitativa dell’origine comune e dell’evoluzione di tutto l’universo osservabile, rappresenta una delle grandi conquiste intellettuali del XX secolo. Detto questo, nel quadro della teoria del Big Bang sono ancora possibili molti modelli diversi: soltanto alla fine del XX secolo si è finalmente avuta la convergenza su un modello particolare, che costituisce il modello standard (detto anche concordance model). Che cosa possiamo invece definire come cosmologia non standard? A parte le teorie alternative al Big Bang che appartengono al passato (come quella dello Stato Stazionario), abbiamo oggi teorie che si propongono di andare al di là del Big Bang e di spiegare ciò che la cosmologia standard per sua natura non è in grado di spiegare. Abbiamo così l’inflazione, i modelli di pre-Big Bang, gli universi-brana, il Multiverso, che a livelli diversi si basano su una nuova fisica non verificata sperimentalmente: siamo dunque in un campo altamente speculativo, ricco di ipotesi e molto lontano dalla pratica quotidiana dell’astronomo. In questo contributo cercherò di seguire una traccia storica e, per quanto riguarda la bibliografia, salvo poche eccezioni rimanderò ad una piccola selezione di review e libri nei quali il lettore potrà trovare i riferimenti agli articoli originali e specialistici. Per un’introduzione aggiornata in lingua italiana alla cosmologia, segnalo il testo a livello universitario di Bonometto(2008). (shrink)

Are physics and chemistry sufficient to provide a basis for a theory of everything? The worldview of materialist naturalism that forms the foundation of NeoDarwinian evolution, Big Bang cosmogony, and molecular biology in general has been subjected to challenge for its monumental failure to explain life, consciousness and other mind-related aspects of reality. Two recent books, Why Evolution is True by Jerry Coyne [1], and Thomas Nagel’s Mind and Cosmos: Why the Materialist NeoDarwinian Conception of Nature Is Almost Certainly False (...) [2], both authors being atheists, reflect the deep rift we find, not only in the religious conflict between creation and evolution, but in the fundamental awareness we all have that we are more than just molecular matter. This common sense understanding can only escape the notice of a particularly shallow ideological dogmatism that insists it has all the answers based solely on its unprecedented technological success. Science has come to represent two different things: (a) a body of knowledge, and (b) a method for acquiring knowledge. The problem arises when it is forgotten that there is no independent body of knowledge for science apart from its method – it keeps changing according to the results of the latest findings of the scientific method. The method is not to be abandoned because of those who would like to replace it with a fixed body of knowledge, which then becomes ideology. If biogenesis is hypothesized as the law of Nature, and we observe that life comes from pre-existing life in all our experience, while the hypothesis of abiogenesis, that life comes from matter, is never backed by any observation, then according to the scientific method—which one is to be accepted as true scientific knowledge? Obviously, the one backed by empirical observation. It is necessary to get free of ideological “knowledge,” and return to science as a method for gathering evidence that may lead to conclusions beyond the material naturalist view of Nature, and conforms to what we experience and rationally understand about the world in which we live.

The mathematical constructions, physical structure and manifestations of physical time are reviewed. The nature of insight and mathematics used to understand and deal with physical time associated with classical, quantum and cosmic processes is contemplated together with a comprehensive understanding of classical time. Scalar time (explicit time or quantitative time), vector time (implicit time or qualitative time), biological time, time of and in conscious awareness are discussed. The mathematical understanding of time in special and general theories of relativity is critically (...) analyzed. The independent nature of classical, quantum and cosmic physical times from one another, and the manifestations of respective physical happenings, distinct from universal time, are highlighted. The role of a universal time related or unrelated to origin, being etc., of universe or cosmos as common thread in all happenings is reviewed. The missing of time is identified and concept of absence of time is put forward. The complex nature of time and the real and imaginary dimensions of physical time are also elaborately discussed together with human time- consciousness as past, present and future. (shrink)

This chapter addresses philosophical questions raised in contemporary work on cosmology. It provides an overview of the Standard Model for cosmology and argues that its deficiency in addressing theories regarding the very early universe can be resolved by introducing a dynamical phase of evolution that eliminates the need for a special initial state. The chapter also discusses recent hypotheses about dark matter and energy, issues that it relates to philosophical debates about underdetermination.

This essay aims to provide a self-contained introduction to time in relativistic cosmology that clarifies both how questions about the nature of time should be posed in this setting and the extent to which they have been or can be answered empirically. The first section below recounts the loss of Newtonian absolute time with the advent of special and general relativity, and the partial recovery of absolute time in the form of cosmic time in some cosmological models. Section II considers (...) the beginning and end of time in a broader class of models in which there is not an analog of Newtonian absolute time. As we will see, reasonable physical assumptions imply that the universe is finite to the past, and Section III turns to consideration of the “beginning” itself. We critically review conventional wisdom that a “singularity” reveals flaws in general relativity and briefly assess ways of avoiding the singularity. (shrink)
