Testing general relativity in cosmology [PDF]

open access: yesLiving Reviews in Relativity, 2018
We review recent developments and results in testing general relativity (GR) at cosmological scales. The subject has witnessed rapid growth during the last two decades with the aim of addressing the question of cosmic acceleration and the dark energy ...

Landauer Principle and General Relativity [PDF]

open access: yesEntropy, 2020
We endeavour to illustrate the physical relevance of the Landauer principle applying it to different important issues concerning the theory of gravitation.

A HERO for General Relativity [PDF]

open access: yesUniverse, 2019
HERO (Highly Eccentric Relativity Orbiter) is a space-based mission concept aimed to perform several tests of post-Newtonian gravity around the Earth with a preferably drag-free spacecraft moving along a highly elliptical path fixed in its plane ...

Quantum Gravity in Everyday Life: General Relativity as an Effective Field Theory

open access: yesLiving Reviews in Relativity, 2004
This article is meant as a summary and introduction to the ideas of effective field theory as applied to gravitational systems, ideas which provide the theoretical foundations for the modern use of general relativity as a theory from which precise ...

The Confrontation between General Relativity and Experiment

open access: yesLiving 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 ...

General Relativity and Philosophy [PDF]

open access: yesJournal 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.

Determinism and General Relativity [PDF]

open access: yesPhilosophy 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’.

Testing General Relativity with Pulsar Timing

open access: yesLiving 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

Nonlocal extension of causal thermodynamics of the isotropic cosmic fluid

open access: yesPhysics 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.
