arXiv:2408.07725v1 Announce Type: new Abstract: In the present paper, we outline and expound the fundamental and novel qualitative-cum-philosophical premises, principles, ideas, concepts, constructions and results that originate from our ongoing research project of applying the conceptual panoply and the technical machinery of Abstract Differential Geometry (ADG) to various persistently outstanding issues in Quantum Gravity (QG) research. At the end of the paper, we discuss the potential philosophical repercussions of two possible future research routes that the main stream of our applications of ADG to QG may bifurcate towards in view of three independent, but overlapping, research papers that are currently under development.

An analysis of the brightest gamma-ray burst ever observed reveals no difference in the propagation speed of different frequencies of light—placing some of the tightest constraints on certain violations of general relativity.

arXiv:2408.06375v1 Announce Type: cross Abstract: A suggestion is made for what happens to a wave function during a measurement. A sequence of interactions with the components of a measurement device is modeled with a simple stochastic process that produces the Born interpretation of quantum mechanical amplitudes.

Wigner’s friend paradoxes highlight contradictions between measurements made by friends inside a laboratory and superobservers outside the laboratory, who have access to an entangled state of the measurement apparatus. Where there are two separated laboratories, the contradictions lead to no-go theo…

The Einstein-Podolsky-Rosen (EPR) paradox gives an argument for the incompleteness of quantum mechanics based on a plausible criterion for reality, as well as the assumption of locality. A general view is that the argument is compromised, because EPR’s premises are falsified by Greenberger-Horne-Zei…

arXiv:2408.05403v1 Announce Type: cross Abstract: Objections to pilot-wave theory frequently come in three mutually-contradictory categories: that the theory is too bizarrely different from ordinary physics, that the theory is not radically different enough, and that the physics of pilot-wave theory is after all just the same as quantum physics. After a brief review of pilot-wave theory, we critically evaluate these objections. We show how the radical nature of pilot-wave theory is often misunderstood or overlooked. We highlight the novelty of its dynamics, and clarify its implications for our understanding of measurement, as well as discussing the status of Lorentz invariance, conservation laws, and the Born rule. We examine Einstein’s early work on pilot-wave theory and argue that he turned away from it for reasons which are no longer compelling. We urge that the theory be understood on its own terms, as a generalised nonequilibrium theory empirically distinct from quantum mechanics, with all its potentially revolutionary implications.

arXiv:2408.05828v1 Announce Type: cross Abstract: I introduce a framework to distinguish two domains of physics – the manifest (i.e. the directly observable empirical records in terms of manifest configurations) and the non-manifest domain of physics (i.e. the things that the manifest configurations signify according to a physical theory). I show that many quantum ‘paradoxes’ rest on ambiguous reasoning about the two domains. More concretely, I study so-called ‘surrealistic’ trajectories, the ‘delayed choice quantum eraser’, and ‘weak measurements’. Finally, I show how the alleged puzzles resolve in the framework provided. I then formally define and address the question of whether quantum uncertainty could be fundamental or whether post-quantum theories could have predictive advantage whilst conforming to the Born rule on average. This notion of what I call ’empirical completeness’ refers to actual prediction-making beyond the Born probabilities, and thus delineates the operational notion of predictability from a ‘hidden variable’ programme in quantum theory. I study how empirical completeness connects to signal-locality, and argue that a partial proof for the impossibility of predictive advantage can be established for bi-partite quantum systems. The relevant results demonstrate signal-locality as a sufficient principle that might explain the fundamental chanciness in present and future quantum theories and, in turn, reconciles us to many quantum features as aspects of limits on Nature’s predictability.

arXiv:2009.02170v3 Announce Type: replace Abstract: After the advent of the theory of special relativity, the existence of absolute time in nature was rejected within the society of physics. In recent decades, William Lane Craig has endeavoured to offer an interpretation of the empirical evidence that support the theory of relativity while maintaining the concept of absolute time. His interpretation, however, is based upon supernatural presuppositions due to which it cannot be accepted as a scientific argument. Here, after explaining Craig’s view, we attempt to reconstruct his explanation for absolute time using the concept of general substantial motion of nature, well-known in Mulla Sadra’s philosophy as the most important approach in Islamic philosophy; thereby, proving general time for the natural world. Although Craig considers some evidence from modern physics in his reasoning for absolute time, in this paper, after pointing to some evidence, it is discussed that the approach used here better bridges the gap that exists between the metaphysics and the physics of the argument.
