Title: Operational verification of the existence of a spacetime manifold
Authors: Nikola Paunkovic and Marko Vojinovic
Abstract summary: We argue that there exists an operational way to establish the objective reality of the notions of space and time. We propose a theory-independent protocol for a gedanken-experiment, whose outcome is a signal establishing the observability of the spacetime manifold.

Abstract: We argue that there exists an operational way to establish the objective reality of the notions of space and time. Specifically, we propose a theory-independent protocol for a gedanken-experiment, whose outcome is a signal establishing the observability of the spacetime manifold, without a priori assuming its existence. The experimental signal contains the information about the dimension and the topology of spacetime (with the currently achievable precision), and establishes its manifold structure, while respecting its underlying diffeomorphism symmetry. We also introduce and discuss appropriate criteria for the concept of emergence of spacetime, which any tentative theoretical model of physics must satisfy in order to claim that spacetime does emerge from some more fundamental concepts.

We introduce Extralonger, which unifies temporal and spatial factors. It notably extends the prediction horizon to a week on real-world benchmarks. It sets new standards in long-term and extra-long-term scenarios.

Relaxation of first-class constraints and the quantization of gauge theories: from "matter without matter" to the reappearance of time in quantum gravity [72.27323884094953]
We make a conceptual overview of an approach to the initial-value problem in canonical gauge theories. We stress how the first-class phase-space constraints may be relaxed if we interpret them as fixing the values of new degrees of freedom.

A Measure-Theoretic Axiomatisation of Causality [55.6970314129444]
We argue in favour of taking Kolmogorov's measure-theoretic axiomatisation of probability as the starting point towards an axiomatisation of causality. Our proposed framework is rigorously grounded in measure theory, but it also sheds light on long-standing limitations of existing frameworks.

Relativity and decoherence of spacetime superpositions [0.0]
In a theory of quantum gravity there exist quantum superpositions of semiclassical states of spacetime geometry. In this paper we introduce a framework for describing such ''quantum superpositions of spacetime states'' We show that for states in which the superposed amplitudes differ by a coordinate transformation, it is always possible to re-express the scenario in terms of dynamics on a single, fixed background.

Is the relativistic Structure of Spacetime Ontic or Epistemic? [0.0]
We argue that Bell's nonlocal correlations cannot readily be explained within the standard relativistic framework. This suggests that we should re-examine our understanding of spacetime.

Time and Evolution in Quantum and Classical Cosmology [68.8204255655161]
We show that it is neither necessary nor sufficient for the Poisson bracket between the time variable and the super-Hamiltonian to be equal to unity in all of the phase space. We also discuss the question of switching between different internal times as well as the Montevideo interpretation of quantum theory.

Quantum nature of time -- proposition of experimental verification [0.0]
The proposed experiment can show that it is possible to have superposition of being created in two different moments in time. It is similar to the case of verification of the possibility of single quantum system to be in the state that is superposition of two different positions in space.

The Relativistic Transactional Interpretation and Spacetime Emergence [0.0]
We consider the manner in which the spacetime manifold emerges from a quantum substratum through the transactional process. There is no background spacetime as is generally assumed in physical theorizing. Specific processes in the quantum substratum serve to distinguish absolute from relative motion.

Quantum Measurement of Space-Time Events [0.0]
The phase space of a relativistic system can be identified with the future tube of complexified Minkowski space. The structures are enough to allow one to put forward a quantum theory of phase-space events.
