Foundations of General Relativity
This Element provides a somewhat comprehensive interpretation of general relativity, a description of what reality would be like if the theory were true. This concerns (i) what possibilities it represents, (ii) the internal structure of those possibilities and their interrelations, and, to some extent, (iii) how those possibilities differ from what's ...

Unimodular gravity vs general relativity: a status report [PDF]
Classical and quantum gravity, 2022 Unimodular gravity (UG) is an alternative to general relativity (GR) which, however, is so closely related to the latter that one can wonder to what extent they are different.

The Confrontation between General Relativity and Experiment
Living Reviews in Relativity, 2001 The status of experimental tests of general relativity and of theoretical frameworks for analysing them are reviewed. Einstein's equivalence principle (EEP) is well supported by experiments such as the Eötvös experiment, tests of special relativity, and ...

Testing General Relativity with Gravitational Waves: An Overview [PDF]
Universe, 2021 The detections of gravitational-wave (GW) signals from compact binary coalescence by ground-based detectors have opened up the era of GW astronomy. These observations provide opportunities to test Einstein’s general theory of relativity at the strong ...

Determinism and General Relativity [PDF]
Philosophy of Science, 2021 We investigate the fate of determinism in general relativity (GR), comparing the philosopher’s account with the physicist’s well-posed initial value formulations. The fate of determinism is interwoven with the question of what it is for a spacetime to be ‘physically reasonable’.

Traversable Wormholes in General Relativity. [PDF]
Physical Review Letters, 2021 Blázquez-Salcedo et al. [Phys. Rev. Lett. 126, 101102 (2021)PRLTAO0031-900710.1103/PhysRevLett.126.101102] obtained asymptotically flat traversable wormhole solutions in the Einstein-Dirac-Maxwell theory without using phantom matter.

General Relativity and Philosophy [PDF]
Journal of Philosophical Investigations, 2021 Is philosophy useful for physics? Many physicists and philosophers believe that it is; but there are those who challenge the usefulness of philosophy for science. Three major objections can be identified in their reasoning: 1.

Nonlocal extension of causal thermodynamics of the isotropic cosmic fluid
Physics Letters B, 2022 We establish the nonlocal generalization of the Israel-Stewart model for the relativistic causal thermodynamics of the cosmic fluid, which evolves in the homogeneous isotropic Universe.

Testing General Relativity with Pulsar Timing
Living Reviews in Relativity, 2003 Pulsars of very different types, including isolated objects and binaries (with short- and long-period orbits, and white-dwarf and neutron-star companions) provide the means to test both the predictions of general relativity and the viability of alternate
