Philosophical problems of space-time theories

Abstract

I present a discussion of some open issues in the philosophy of space-time theories. Emphasis is put on the ontological nature of space and time, the relation between determinism and predictability, the origin of irreversible processes in an expanding Universe, and the compatibility of relativity and quantum mechanics. In particular, I argue for a Parmenidean view of time and change, I make clear the difference between ontological determinism and predictability, propose that the origin of the asymmetry observed in physical processes is related to the existence of cosmological horizons, and present a non-local concept of causality that can accommodate both special relativity and quantum entanglement.

What implications does logical empiricism have for contemporary physics interpretations?add

The study reveals that logical empiricism has enhanced precision and formalization in interpreting scientific theories, especially in analyzing quantum mechanics and general relativity since the mid-20th century.

How do historical views on space and time shape modern theories?add

The paper finds that philosophical debates from Heraclitus to Newton laid foundational ideas influencing contemporary theories, including space-time as a four-dimensional manifold.

What are the relational concepts of space-time proposed by Leibniz?add

Leibniz argued that space and time are merely relational, asserting that their existence relies on the relations between objects rather than on absolute entities.

How does causal non-locality affect interpretations of quantum mechanics?add

The research suggests that acknowledging non-local causation provides a consistent framework to resolve quantum entanglement without violating relativistic principles.

Why is the concept of the 'block Universe' relevant to determinism in physics?add

The concept highlights a four-dimensional reality where all events exist simultaneously, challenging traditional notions of time and reinforcing deterministic interpretations of physical laws.

Space, Time, and (how they) Matter: a Discussion about some Metaphysical Insights Provided by our Best Fundamental Physical Theories
valia allori

2016

This paper is a brief (and hopelessly incomplete) non-standard introduction to the philosophy of space and time. It is an introduction because I plan to give an overview of what I consider some of the main questions about space and time: Is space a substance over and above matter? How many dimensions does it have? Is space-time fundamental or emergent? Does time have a direction? Does time even exist? Nonetheless, this introduction is not standard because I conclude the discussion by presenting the material with an original spin, guided by a particular understanding of fundamental physical theories, the so-called primitive ontology approach.

The True Nature of Space-Time
KAMAL BARGHOUT

viXra, 2015

The change of the state of motion of physical systems is characterized by the change of its velocity; an important aspect of Relativity Theory (RT). Quantum mechanics (QM) implies space-time itself may be quantum in nature if QM is to comply with RT geometrically; i.e. Loop quantum gravity theory (LQG) as a quantum space-time. The nature of time and its intimate relationship with space as described by RT is not so obviously defined but dealt with as an abstract entity that exists in physical reality. But physical reality demands similar dynamical space-time notion as mostly expressed by LQG. Here, following the concept of quantum space-time, I describe time as a numerical value of space such that the rules of RT are satisfied. Length contraction, time dilation and the forward arrow of time are explained accordingly. The intention here is to add dynamical aspect to the notion of time by defining it as a property of the dynamical space itself under the rules of RT but adding a dynamic...

Fundamental Nature of Space-Time
Satinder S I N G H Malik

Scientific GOD Journal, 2023

This paper lays a hypothesis about the fundamental nature of Space and Time. Time is absolute as well as relative. Relative quantity can occur only if the absolute exists in the theory. It is an established fact that elementary particles such as quarks keep forming up in space and keep decaying. This happens in the quantum foam due to the presence of quantum vacuum fluctuations. The quantum vacuum fluctuations are caused by time energy as per the design of Consciousness (sentience). This theory aims to explain the workings of relative time, motion in the cosmos and the source of energy of the quarks, electrons and other elementary particles. This model accounts for observations such as the correlation of distance and redshift of galaxies. The conclusions of the paper are as follows: (g) Consciousness is a para dimension besides space, time, energy, matter and intelligence. (h) The homogeneity, isotropism and continuous expansion of space may be an incorrect conclusion.

New Perspectives on the Relationship of Space and Time Within General Relativity and Quantum Mechanics
Nikola Perkovic

viXra, 2016

This paper innovates the way we comprehend time and its relationship with space by proposing a new concept within General relativity and, to some extent, Quantum Mechanics in order to explain some of the natural aspects that still puzzle scientists that study the very nature of the Universe. Gravitation, the arrow of time, cosmic inflation and many more subjects that are crucial to modern day physics shall be debated within the most accurate theory, General relativity, but also with some concepts developed in terms of Quantum Mechanics.

Axiomatic causal theory of space-time
Alexander К O N S T A N T I N O V I C H Guts

Gravitation and Cosmology

Principles of construction of a causal space-time theory are discussed. A system of axioms for Special Relativity Theory, which postulates the macrocausality and continuity of time order, is considered. The posibilities of a topos-theoretic approach to the foundations of Relativity Theory are investigated. Construction of a causal theory of space-time is one of the most attractive tasks of science in the 20th century. From the viewpoint of mathematics, partially ordered structures should be considered. The latter is commonly understood as a set V with a specified reflexive and transitive binary relation. A primary notion is actually not that of causality but rather that of motion (interaction) of material objects. Causality is brought to the foreground since an observer detects changes of object motion or state. It is this detection that gives rise to the view of a particular significance of causes and effects for a phenomenon under study, along with the conviction that causal connections are non-symmetric. Causality is treated as such a relation in the material world that plays a key role in explaining the topological, metric and all other world structures.

Philosophy Beyond Spacetime: Introduction
Christian Wuthrich

2021

The present volume collects essays on the philosophical foundations of quantum theories of gravity, such as loop quantum gravity and string theory. Central for philosophical concerns is quantum gravity's suggestion that space and time, or spacetime, may not exist fundamentally, but instead be a derivative entity emerging from non-spatiotemporal degrees of freedom. In the spirit of naturalised metaphysics, contributions to this volume consider the philosophical implications of this suggestion. In turn, philosophical methods and insights are brought to bear on the foundations of quantum gravity itself. For instance, the idea of functionalism, borrowed from the philosophy of mind and discussed by several essays, exemplifies this mutual interaction the collection seeks to foster.

Relativity of Space-Time & the Cause
Himangsu Sekhar Pal

Scientific GOD Journal, 2018

In this essay, I show that the cause that makes space and time to be relative in our universe must lie outside our universe. Otherwise, we will have to admit that there was a time when they were not relative, but absolute.

In Causality Principle as the Framework to Contextualize Time in Modern Physics
Maury Jackson

2016

Since the moment Boethius meditated on the nature of time in his fifth book on The Consolation of Philosophy, we have more tools to reflect on the subject. The onset of relativity and quantum physics provides us with the best insight, to date, that guides our reflections on the philosophical debates that attempt to theorize a definition of time. To clearly address the problems related to the theoretical models that account for the nature of time, adjustments to our interpretation of the contextual issues involved in special relativity are in order if we are going to preserve our notion of causal reality. As the construction of string theory emerges as the reigning theory for quantum gravity, a precise picture of causal reality can be accounted for through theories such as Dyson’s Chronological Protection Agency, Hořava’s theory of gravity, and new insight to how simultaneity is interpreted in relativity theory. With this model, the question about time in the philosophical debates ca...

Space, time, and irreversibility: The philosophical problems of contemporary
Gustavo E Romero

Mètode Revista de difusió de la investigació, 2016

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.

Philosophy of Space-Time Physics
Craig Callender

Machamer/The Blackwell, 2008

Philosophy of space-time physics, as opposed to the more general philosophy of space and time, is the philosophical investigation of special and general relativity. Relativity theory stimulated immediate and deep philosophical analysis, both because of its novel implications for the nature of space, time and matter, and because of more general questions philosophers have about the nature of its claims. With nearly one hundred years of sustained research to draw on, this chapter cannot hope to survey all the topics that have arisen, even all the major ones. Instead, we concentrate on four topics, two with a historical and philosophical pedigree, namely, relationalism and conventionalism, and two that arise in general relativity and cosmology, namely, singularities and the so-called horizon problem. This selection should give the reader a representative taste of the field as it stands today. Many fascinating topics, however, will not be covered. Notable examples are the topics of time travel, presentism, supertasks, and the Lorentz interpretation of relativity. For up-to-date references and discussions of these topics, the reader can turn to, respectively,

Causality and Determinism in Modern Physics
Grzegorz Bugajak

Knowledge and Values, ed. Adam Świeżyński, Wyd. UKSW, Warszawa 2011, pp. 73–94., 2011

The paper revisits the old controversy over causality and determinism and argues, in the first place, that non˗deterministic theories of modern science are largely irrelevant to the philosophical issue of the causality principle. As it seems to be the ‘moral’ of the uncertainty principle, the reason why a deterministic theory cannot be applied to the description of certain physical systems is that it is impossible to capture such properties of the system, which are required by a desired theory. These properties constitute what is called ‘the state’ of a system. However, the notion of a state of a system is relative: it depends on a particular theory which one would like to use to describe given kinds of phenomena. This implies that, even in the case where the desired state of a system is fundamentally impossible to be captured, neither ontological nor epistemological determinism may be excluded. Some following critical considerations are also offered with regard to the claim that uncertainty is “rooted in the things themselves”. The cradle of modern discussions about causality and determinism is, of course, quantum mechanics. Because, as it appears, a judgment on deterministic or non˗deterministic character of a theory can be made only after some interpretation of this theory has been given, the paper briefly reminds some chosen interpretations of quantum mechanics (Schrödinger's, probabilistic, statistical, Copenhagen, and the interpretation of quantum ensembles). Many of such interpretations, offered in the past, have now been rejected, and some gained more credibility than the others. Nonetheless, even the claim that indeterminism is irremovable from the description of the micro-world doesn't imply the rejection of the most general formula of the philosophical causality principle. There is no direct implication between theses of the epistemology of scientific knowledge and those of the ontology of the real world.

Causal Theories of Spacetime
Baptiste Le Bihan

Noûs, 2023

We develop a new version of the causal theory of spacetime. Whereas traditional versions of the theory seek to identify spatiotemporal relations with causal relations, the version we develop takes causal relations to be the grounds for spatiotemporal relations. Causation is thus distinct from, and more basic than, spacetime. We argue that this non-identity theory, suitably developed, avoids the challenges facing the traditional identity theory.
