    Introduction dans les théories de la relativité.Nicolae Sfetcu - manuscript
    Selon la relativité générale, la force gravitationnelle est une manifestation de la géométrie de l'espace-temps local. RG est une théorie métrique de la gravité. Il est basé sur les équations d'Einstein, qui décrivent la relation entre la géométrie d'une variété pseudo-riemannienne à quatre dimensions, représentant l'espace-temps et l'énergie-impulsion contenu dans cet espace-temps. La gravité correspond aux modifications des propriétés spatiales et temporelles, qui à leur tour modifient les chemins des objets. La courbure est causée par l'énergie-impulsion de la matière. Selon (...)

    Classical Theory of Singularities.Nicolae Sfetcu - manuscript
    The singularities from the general relativity resulting by solving Einstein's equations were and still are the subject of many scientific debates: Are there singularities in spacetime, or not? Big Bang was an initial singularity? If singularities exist, what is their ontology? Is the general theory of relativity a theory that has shown its limits in this case?

    Covariance/Invariance: A Cognitive Heuristic in Einstein's Relativity Theory Formation.Andrea Cerroni - 2000 - Foundations of Science 5 (2):209-224.
    Relativity Theory by Albert Einstein has been so far littleconsidered by cognitive scientists, notwithstanding its undisputedscientific and philosophical moment. Unfortunately, we don't have adiary or notebook as cognitively useful as Faraday's. But physicshistorians and philosophers have done a great job that is relevant bothfor the study of the scientist's reasoning and the philosophy ofscience. I will try here to highlight the fertility of a `triangulation'using cognitive psychology, history of science and philosophy of sciencein starting answering a clearly very complex question:why (...)

    What Is the Validity Domain of Einstein’s Equations? Distributional Solutions Over Singularities and Topological Links in Geometrodynamics.Elias Zafiris - 2016 - 100 Years of Chronogeometrodynamics: The Status of the Einstein's Theory of Gravitation in Its Centennial Year.
    The existence of singularities alerts that one of the highest priorities of a centennial perspective on general relativity should be a careful re-thinking of the validity domain of Einstein’s field equations. We address the problem of constructing distinguishable extensions of the smooth spacetime manifold model, which can incorporate singularities, while retaining the form of the field equations. The sheaf-theoretic formulation of this problem is tantamount to extending the algebra sheaf of smooth functions to a distribution-like algebra sheaf in which the (...)

    On the Fundamental Role of Massless Form of Matter in Physics.Alexander Klimets - 2017 - FIZIKA B (Zagreb) 9:23-42.
    In the article, with the help of various models, the thesis on the fundamental nature of the field form of matter in physics is considered. In the first chapter a model of special relativity is constructed, on the basis of which the priority of the massless form of matter is revealed. In the second chapter, a field model of inert and heavy mass is constructed and on this basis the mechanism of inertia and gravity of weighty bodies is revealed. In (...)

    Part 3: Programming Atomic and Gravitational Orbitals in a Simulation Hypothesis.Malcolm J. Macleod - manuscript
    This article introduces a method for programming orbitals at the Planck level. Mathematical probability orbitals are replaced with units of `orbit momentum' with orbital regions derived from geometrical imperatives rather than abstract forces. In this approach the electron does not orbit around a nucleus but rather is maintained within an orbital region by the confines of the geometry of the orbital (this orbit momentum is the orbital). There is no electron transition between orbitals, rather the existing orbital is exchanged for (...)

    Anchoring Causal Connections in Physical Concepts.Roland Poellinger & Mario Hubert - 2014 - In Maria Clara Galavotti, Dennis Dieks, W. J. Gonzalez, Stephan Hartmann, Thomas Uebel & Marcel Weber (eds.), New Directions in the Philosophy of Science. pp. 501-509.
    In their paper "How Fundamental Physics represents Causality", Andreas Bartels and Daniel Wohlfarth maintain that there is place for causality in General Relativity. Their argument contains two steps: First they show that there are time-asymmetric models in General Relativity, then they claim to derive that two events are causally connected if and only if there is a time-asymmetric energy flow from one event to the other. In our comment we first give a short summary of their paper followed by a (...)

    Have We Lost Spacetime on the Way? Narrowing the Gap Between General Relativity and Quantum Gravity.Baptiste Le Bihan & Niels Linnemann - forthcoming - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics.
    Important features of space and time are taken to be missing in quantum gravity, allegedly requiring an explanation of the emergence of spacetime from non-spatio-temporal theories. In this paper, we argue that the explanatory gap between general relativity and non-spatio- temporal quantum gravity theories might signifi cantly be reduced with two moves. First, we point out that spacetime is already partially missing in the context of general relativity when understood from a dynamical perspective. Second, we argue that most approaches to (...)

    Matters of Time Directionality in Classical Physics.Jean-Christophe Lindner - manuscript
    A complete and up-to-date analysis of the question of time directionality as it arises in a semi-classical context is provided which is based on key developments related to the theory of gravitation. Important clarifications are achieved regarding the concept of time reversal as a concept independent from the thermodynamic arrow of time. The role played by the Leibnizian constraint of relational definition of physical properties applied to the sign of electric charge and the energy of elementary particles is thoroughly examined (...)

    Background Independence: Lessons for Further Decades of Dispute.Trevor Teitel - 2018 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics.
    Background independence begins life as an informal property that a physical theory might have, often glossed as 'doesn't posit a fixed spacetime background'. Interest in trying to offer a precise account of background independence has been sparked by the pronouncements of several theorists working on quantum gravity that background independence embodies in some sense an essential discovery of the General Theory of Relativity, and a feature we should strive to carry forward to future physical theories. This paper has two goals. (...)

    Defining a Crisis: The Roles of Principles in the Search for a Theory of Quantum Gravity.Karen Crowther - forthcoming - Synthese:1-28.
    In times of crisis, when current theories are revealed as inadequate to task, and new physics is thought to be required---physics turns to re-evaluate its principles, and to seek new ones. This paper explores the various types, and roles of principles that feature in the problem of quantum gravity as a current crisis in physics. I illustrate the diversity of the principles being appealed to, and show that principles serve in a variety of roles in all stages of the crisis, (...)

    Teleportative Observers Versus Special Relativity Observers: Work in Progress.James Goetz - manuscript
    Various authors argue that special relativity implies eternalism. For example, special relativity observers are limited by the relativity of simultaneity and cannot detect a preferred universal chronology, which is an important premise for the Rietdijk–Putnam argument which implies eternalism. However, I introduce "teleportative observers" which cohere with wormhole theory based on general relativity. Teleportative observers do not teleport objects but use hypothetical teleportative sight to detect every event in every quantum system of the universe. The teleportative sight permits detection at (...)

    A Study of Time in Modern Physics.Peter W. Evans - 2011 - Dissertation,
    This thesis is a study of the notion of time in modern physics, consisting of two parts. Part I takes seriously the doctrine that modern physics should be treated as the primary guide to the nature of time. To this end, it offers an analysis of the various conceptions of time that emerge in the context of various physical theories and, furthermore, an analysis of the relation between these conceptions of time and the more orthodox philosophical views on the nature (...)

    Presentism and Relativity.Steven Umbrello - 2015 - The Oxford Philosopher.
    In this short paper I will be explicating and evaluating the arguments presented by Keller and Nelson in their paper, Presentists Should Believe in Time-Travel. I will show that their presuppositions, which are essential to their arguments, have the potential to devastate their position. We will see that one of these presuppositions comes into conflict with the General Theory of Relativity, and I will demonstrate that this endangers both their own agenda and presentism as a whole.

    General Relativity Eliminates Dark Energy, Dark Matter and Universal Expansion.Rodney Bartlett - 2018
    This letter was rejected by International Knowledge Press because "we are unable to conclude that these findings would warrant publication in this journal." The letter is suggesting that dark energy, dark matter and universal expansion are intimately related. However, they aren't viewed as revolutions in cosmology which are essential to a complete understanding of the modern universe. They are instead viewed as properties which need to be added to the cosmos when Einstein's theory of gravity (General Relativity) is apparently still (...)

    Inter-Theory Relations in Quantum Gravity: Correspondence, Reduction, and Emergence.Karen Crowther - 2017 - Studies in History and Philosophy of Modern Physics.
    Relationships between current theories, and relationships between current theories and the sought theory of quantum gravity (QG), play an essential role in motivating the need for QG, aiding the search for QG, and defining what would count as QG. Correspondence is the broad class of inter-theory relationships intended to demonstrate the necessary compatibility of two theories whose domains of validity overlap, in the overlap regions. The variety of roles that correspondence plays in the search for QG are illustrated, using examples (...)

    In General Relativity, Gravity is Effect of Coordinates with Change of Geometry of Spacetime.Alfonso Leon Guillen Gomez - manuscript
    Einstein structured the theoretical frame of his work on gravity under the Special Relativity and Minkowski´s spacetime using three guide principles: The strong principle of equivalence establishes that acceleration and gravity are equivalents. Mach´s principle explains the inertia of the bodies and particles as completely determined by the total mass existent in the universe. And, general covariance searches to extend the principle of relativity from inertial motion to accelerated motion. Mach´s principle was abandoned quickly, general covariance resulted mathematical property of (...)

    An Alternative to the Schwarzschild Solution of GTR.Andrew Thomas Holster - manuscript
    The Schwarzschild solution (Schwarzschild, 1915/16) to Einstein’s General Theory of Relativity (GTR) is accepted in theoretical physics as the unique solution to GTR for a central-mass system. In this paper I propose an alternative solution to GTR, and argue it is both logically consistent and empirically realistic as a theory of gravity. This solution is here called K-gravity. The introduction explains the basic concept. The central sections go through the technical detail, defining the basic solution for the geometric tensor, the (...)

    Renormalizability, Fundamentality and a Final Theory: The Role of UV-Completion in the Search for Quantum Gravity.Karen Crowther & Niels Linnemann - 2017 - British Journal for the Philosophy of Science:axx052.
    Principles are central to physical reasoning, particularly in the search for a theory of quantum gravity (QG), where novel empirical data is lacking. One principle widely adopted in the search for QG is UV completion: the idea that a theory should (formally) hold up to all possible high energies. We argue---/contra/ standard scientific practice---that UV-completion is poorly-motivated as a guiding principle in theory-construction, and cannot be used as a criterion of theory-justification in the search for QG. For this, we explore (...)

    The General Relativity Genesis: an Intertheoretic Context.Rinat M. Nugayev - 2017 - Voprosi Filosofii (The Problems of Philosophy) (1):62-70.
    Abstract. The theory-change epistemological model, tried on maxwellian revolution and special relativity genesis, is unfolded to apprehend general relativity genesis. It is exhibited that the dynamics of general relativity (GR) construction was largely governed by internal tensions of special relativity and Newton’s theory of gravitation. The research traditions’ encounter engendered construction of the hybrid domain at first with an irregular set of theoretical models. However, step by step, on revealing and gradual eliminating the contradictions between the models involved, the hybrid (...)

    Fifty Million Elvis Fans Can't Be Wrong.Gordon Belot - 2018 - Noûs:946-981.
    This essay revisits some classic problems in the philosophy of space and time concerning the counting of possibilities. I argue that we should think that two Newtonian worlds can differ only as to when or where things happen and that general relativistic worlds can differ in something like the same way—the first of these theses being quaintly heterodox, the second baldly heretical, according to the mores of contemporary philosophy of physics.

    Time Remains.Sean Gryb & Karim P. Y. Thébault - 2016 - British Journal for the Philosophy of Science 67 (3):663-705.
    On one popular view, the general covariance of gravity implies that change is relational in a strong sense, such that all it is for a physical degree of freedom to change is for it to vary with regard to a second physical degree of freedom. At a quantum level, this view of change as relative variation leads to a fundamentally timeless formalism for quantum gravity. Here, we will show how one may avoid this acute ‘problem of time’. Under our view, (...)

    Two radically different views about time are possible. According to the first, the universe is three dimensional. It has a past and a future, but that does not mean it is spread out in time as it is spread out in the three dimensions of space. This view requires that there is an unambiguous, absolute, cosmic-wide "now" at each instant. According to the second view about time, the universe is four dimensional. It is spread out in both space and time (...)

From the theoretical point view “the question of precisely what Einstein discovered remains unanswered, for we have no consensus over the exact nature of the theory 's foundations.

    Gravity, Metaphysics or Physics ?Alfonso Leon Guillen Gomez - 2013 - International Journal of Fundamental Physical Sciences 3 (4):68 - 74.
    Gravity is the foundation of the current physical paradigm. Due to that gravity is strongly linked to the curvature of space-time, we research that it lacks of a valid physical concept of space-time, nevertheless that from the science philosophy, via substantivalism, it has tried respond. We found that is due to that the gnoseological process applied from the general relativity, necessarily us leads to metaphysic because ontologically space-time is a metaphysical entity. Thus, we arrive to the super substantivalism that from (...)

    Relativity and Three Four‐Dimensionalisms.Cody Gilmore, Damiano Costa & Claudio Calosi - 2016 - Philosophy Compass 11 (2):102-120.
    Relativity theory is often said to support something called ‘the four-dimensional view of reality’. But there are at least three different views that sometimes go by this name. One is ‘spacetime unitism’, according to which there is a spacetime manifold, and if there are such things as points of space or instants of time, these are just spacetime regions of different sorts: thus space and time are not separate manifolds. A second is the B-theory of time, according to which the (...)

    Scrutiny of Einstein's Geodesic and Field Equations.Mohamed Elmansour Hassani - manuscript
    Since its final version and publication in 1916, it is widely reported in several specialized textbooks and research articles that general relativity theory may be reduced to the Newton's gravity theory in the limit of a weak gravitational field and slow motion of the material bodies. In the present paper, the so-called reducibility of Einstein's geodesic and field equations to Newton's equation of motion and Poisson's gravitational potential equation, respectively, is scrutinized and proven to be mathematically, physically and dimensionally wrong (...)

    Prediction in General Relativity.C. McCoy - 2017 - Synthese 194 (2):491-509.
    Several authors have claimed that prediction is essentially impossible in the general theory of relativity, the case being particularly strong, it is said, when one fully considers the epistemic predicament of the observer. Each of these claims rests on the support of an underdetermination argument and a particular interpretation of the concept of prediction. I argue that these underdetermination arguments fail and depend on an implausible explication of prediction in the theory. The technical results adduced in these arguments can be (...)

    Space-Time Dimension Problem as a Stumbling Block of Inflationary Cosmology.Rinat M. Nugayev - 2013 - In Vadim V. Kazutinsky, Elena A. Mamchur, Alexandre D. Panov & V. D. Erekaev (eds.), Metauniverse,Space,Time. Institute of Philosophy of RAS. pp. 52-73.
    It is taken for granted that the explanation of the Universe’s space-time dimension belongs to the host of the arguments that exhibit the superiority of modern (inflationary) cosmology over the standard model. In the present paper some doubts are expressed . They are based upon the fact superstring theory is too formal to represent genuine unification of general relativity and quantum field theory. Neveretheless, the fact cannot exclude the opportunity that in future the superstring theory can become more physical. Hence (...)

    Origin and Resolution of Theory-Choice Situations in Modern Theory of Gravity.Rinat M. Nugayev - 1987 - Methodology and Science 20 (4):177-197.
    A methodological model of origin and settlement of theory-choice situations (previously tried on the theories of Einstein and Lorentz in electrodynamics) is applied to modern Theory of Gravity. The process of origin and growth of empirically-equivalent relativistic theories of gravitation is theoretically reproduced. It is argued that all of them are proposed within the two rival research programmes – (1) metric (A. Einstein et al.) and (2) nonmetric (H. Poincare et al.). Each programme aims at elimination of the cross-contradiction between (...)

    Time in Classical and Relativistic Physics.Gordon Belot - 2013 - In Adrian Bardon & Heather Dyke (eds.), A Companion to the Philosophy of Time. Blackwell. pp. 185-200.
    This is a short, nontechnical introduction to features of time in classical and relativistic physics and their representation in the four-dimensional geometry of spacetime. Topics discussed include: the relativity of simultaneity in special and general relativity; the ‘twin paradox’ and differential aging effects in special and general relativity; and time travel in general relativity.

    Quantum Mechanics Foundations.Bakytzhan Oralbekov - manuscript
    Gravity remains the most elusive field. Its relationship with the electromagnetic field is poorly understood. Relativity and quantum mechanics describe the aforementioned fields, respectively. Bosons and fermions are often credited with responsibility for the interactions of force and matter. It is shown here that fermions factually determine the gravitational structure of the universe, while bosons are responsible for the three established and described forces. Underlying the relationships of the gravitational and electromagnetic fields is a symmetrical probability distribution of fermions and (...)

    Dynamical Versus Structural Explanations in Scientific Revolutions.Mauro Dorato - 2017 - Synthese 194 (7):2307-2327.
    By briefly reviewing three well-known scientific revolutions in fundamental physics (the discovery of inertia, of special relativity and of general relativity), I claim that problems that were supposed to be crying for a dynamical explanation in the old paradigm ended up receiving a structural explanation in the new one. This claim is meant to give more substance to Kuhn’s view that revolutions are accompanied by a shift in what needs to be explained, while suggesting at the same time the existence (...)
