  1. Does Inflation Solve the Hot Big Bang Model׳s Fine-Tuning Problems?C. D. McCoy - 2015 - Studies in History and Philosophy of Modern Physics 51:23-36.
    Cosmological inflation is widely considered an integral and empirically successful component of contemporary cosmology. It was originally motivated by its solution of certain so-called fine-tuning problems of the hot big bang model, particularly what are known as the horizon problem and the flatness problem. Although the physics behind these problems is clear enough, the nature of the problems depends on the sense in which the hot big bang model is fine-tuned and how the alleged fine-tuning is problematic. Without clear (...)

    Stability in Cosmology, From Einstein to Inflation.C. D. McCoy - 2020 - In Claus Beisbart, Tilman Sauer & Christian Wüthrich (eds.), Thinking About Space and Time. Cham: Birkhäuser. pp. 71-89.
    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 (...)

  5. Predictability Crisis in Early Universe Cosmology.Chris Smeenk - 2014 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 46 (1):122-133.
    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 (...)

  6. Review of The Inflationary Universe by Alan Guth (1997).Michael Starks - 2016 - In Suicidal Utopian Delusions in the 21st Century: Philosophy, Human Nature and the Collapse of Civilization-- Articles and Reviews 2006-2017 2nd Edition Feb 2018. Michael Starks. pp. 615-618.
    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 (...)

  7. Compartmentalized Knowledge.Levi Spectre - 2019 - Philosophical Studies 176 (10):2785-2805.
    This paper explores some consequences of Lewis’s (Australas J Philos 74(4):549–567, 1996) understanding of how knowledge is compartmentalized. It argues, first, that he underestimates how badly it impacts his view. When knowledge is compartmentalized, it lacks at least one of two essential features of Lewis’s account: (a) Elusiveness—familiar skeptical possibilities, when relevant, are incompatible with everyday knowledge. (b) Knowledge is a modality—when a thinker knows that p, there is no relevant possibility where p is false. Lewis proposes compartmentalized knowledge to (...)

  8. Time in Cosmology.C. D. McCoy & Craig Callender - forthcoming - In Eleanor Knox & Alistair Wilson (eds.), Routledge Companion to the Philosophy of Physics.
    Readers familiar with the workhorse of cosmology, the hot big bang model, may think that cosmology raises little of interest about time. As cosmological models are just relativistic spacetimes, time is understood just as it is in relativity theory, and all cosmology adds is a few bells and whistles such as inflation and the big bang and no more. The aim of this chapter is to show that this opinion is not completely right...and may well be dead wrong. In (...)

  9. The Emergence of Causation.J. Dmitri Gallow - 2015 - Journal of Philosophy 112 (6):281-308.
    Several philosophers have embraced the view that high-level events—events like Zimbabwe's monetary policy and its hyper-inflation—are causally related if their corresponding low-level, fundamental physical events are causally related. I dub the view which denies this without denying that high-level events are ever causally related causal emergentism. Several extant philosophical theories of causality entail causal emergentism, while others are inconsistent with the thesis. I illustrate this with David Lewis's two theories of causation, one of which entails causal emergentism, the other (...)

  11. Self-Deception Won't Make You Happy.Neil Van Leeuwen - 2009 - Social Theory and Practice 35 (1):107-132.
    I argue here that self-deception is not conducive to happiness. There is a long train of thought in social psychology that seems to say that it is, but proper understanding of the data does not yield this conclusion. Illusion must be distinguished from mere imagining. Self-deception must be distinguished from self-inflation bias and from self-fulfilling belief. Once these distinctions are in place, the case for self-deception falls apart. Furthermore, by yielding false beliefs, self-deception undermines desire satisfaction. Finally, I argue (...)

    A Model for Creation: Part I.Paul Bernard White - manuscript
    Four initial postulates are presented (with two more added later), which state that construction of the physical universe proceeds from a sequence of discrete steps or "projections" --- a process that yields a sequence of discrete levels (labeled 0, 1, 2, 3, 4). At or above level 2 the model yields a (3+1)-dimensional structure, which is interpreted as ordinary space and time. As a result, time does not exist below level 2 of the system, and thus the quantum of action, (...)

    Current health care standards, in many countries, Australia included, are regrettably poor. Surprisingly, practitioners and treating teams alike in mental health and disability sectors, in particular, make far too many basic care-related mistakes, in addition to the already abundant diagnostic mistakes that cause and amplify great harm. In part, too many practitioners also fail to distinguish adverse effects for what they are and all too often treat adverse effects, instead, as comorbidities. Diagnostic failures are dangerous, the result of which generates (...)

  15. Representational Monetary Identity.Mirelo Deugh Ausgam Valis - 2013 - Lulu.
    Whenever debt is itself money, this money becomes a self-inflating debt principal by already being its own interest. Hence modern inflation, deflation, and eventual monetary crises. Yet why does money become debt? The concept of representational monetary identity answers to precisely this question.

  16. Classical Probability, Shakespearean Sonnets, and Multiverse Hypotheses.James Goetz - 2006 - International Society for Complexity, Information, and Design Archive 2006.
    We evaluate classical probability in relation to the random generation of a Shakespearean sonnet by a typing monkey and the random generation of universes in a World Ensemble based on various multiverse models involving eternal inflation. We calculate that it would take a monkey roughly 10^942 years to type a Shakespearean sonnet, which pushes the scenario into a World Ensemble. The evaluation of a World Ensemble based on various models of eternal inflation suggests that there is no middle (...)

  17. Matters of Time Directionality in Gravitational Physics.Jean-Christophe Lindner - manuscript
    This report offers a modern perspective on the question of time directionality as it arises in a semi-classical context, based on key developments in the field of gravitational physics. Important clarifications are achieved regarding, in particular, the concepts of time reversal and negative energy. The conditions imposed by the Leibnizian constraint of relational definition of physical attributes are thoroughly examined and significant consequences of applying this consistency requirement are derived. From this analysis emerges an improved understanding of the general relativistic (...)

Im zweiten Abschnitt werde ich vier Domänen kognitiver Erweiterung auseinanderhalten, nämlich eine Erweiterung in die körperliche, physikalische, 'informatorische' und soziale Umgebung betreffend.

  19. On H. M. Oliver’s “Established Expectations and American Economic Policies”.Govind Persad - 2015 - Ethics 125 (3):829-832,.
    In this retrospective for Ethics, I discuss H.M. Oliver’s “Established Expectations and American Economic Policies.” This article, by a then-modestly-famous economist, has been ignored (no citations) since its 1940 publication. Yet it bears directly on a normative problem at the intersection of ethics and economics that challenges today’s policymakers but has received comparatively little philosophical attention: how should we balance potentially desirable institutional change against the disruption of established expectations? -/- Oliver details how the principle of fulfilling established expectations cuts (...)

    Extensions of Quantum Gravity Theories - Final Theory and Cosmology.Nicolae Sfetcu - manuscript
    The fields of application of general relativity (GR) and quantum field theory (QFT) are different, so most situations require the use of only one of the two theories. The overlaps occur in regions of extremely small size and high mass, such as the black hole or the early universe (immediately after the Big Bang). This conflict is supposed to be solved only by unifying gravity with the other three interactions, to integrate GR and QFT into one theory. At the cosmological (...)

  21. Supporting Abstract Relational Space-Time as Fundamental Without Doctrinism Against Emergence.Sascha Vongehr - manuscript
    The present paper aims to contribute to the substantivalism versus relationalism debate and to defend general relativity (GR) against pseudoscientific attacks in a novel, especially inclusive way. This work was initially motivated by the desire to establish the incompatibility of any ether theories with accelerated cosmic expansion and inflation (motto: where would a hypothetical medium supposedly come from so fast?). The failure of this program is of interest for emergent GR concepts in high energy particle physics. However, it becomes (...)

It warns on practical and principled grounds against conceptual inflation of the notion of "health" as it appears in theories of distributive justice. Second, it considers how various (...)

    A Derivation of Space and Time.Paul Bernard White - 2019 - Progress in Physics 15 (2).
    Four simple postulates are presented, from which we derive a (3+1)‑dimensional structure, interpreted as ordinary space and time. We then derive further properties of space: isotropy and homogeneity; a rapid expansion within the first instant of time (i.e. inflation); and a continual and uniform expansionary pressure, due to a continual influx of (non-zero-point) energy that is uniformly distributed (i.e. dark energy). In addition, the time dimension is shown to have an "arrow". These results suggest that the four postulates may (...)

    The Kalam Cosmological Argument: Critiquing a Recent Defence.Phillip Halper - 2021 - Think 20 (57):153-165.
    ABSTRACTIn the late 1970s the big bang model of cosmology was widely accepted and interpreted as implying the universe had a beginning. At the end of that decade William Lane Craig revived an argument for God known as the Kalam Cosmological Argument based on this scientific consensus. Furthermore, he linked the big bang to the supposed biblical concept of creation ex nihilo found in Genesis. I shall critique Craig's position as expressed in a more recent update and argue that contemporary (...)

    Unemployment has been at historically high rates for an extended period, and while it has recently improved in certain countries, the unemployment that remains may be becoming structural. Aside from inequality, unemployment is accordingly the problem that is most likely to put critical pressure on our political institutions, disrupt the social fabric of our way of life, and even threaten the continuation of liberalism itself. Despite the obvious importance of the problem of unemployment, however, there has been a curious lack (...)

    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 (...)
