Testing different approaches to quantum gravity with cosmology: An overview [PDF]

, 2017
Among the available quantum gravity proposals, string theory, loop quantum gravity, non-commutative geometry, group field theory, causal sets, asymptotic safety, causal dynamical triangulation, emergent gravity are among the best motivated models. As an introductory summary to this special issue of Comptes Rendus Physique, I explain how those different

Vienna Circle and Logical Analysis of Relativity Theory

, 2011
In this paper we present some of our school's results in the area of building up relativity theory (RT) as a hierarchy of theories in the sense of logic.

Resource Letter PTG-1: Precision Tests of Gravity

, 2010
This resource letter provides an introduction to some of the main current topics in experimental tests of general relativity as well as to some of the historical literature. It is intended to serve as a guide to the field for upper-division undergraduate

The Struble-Einstein Correspondence [PDF]

arXiv, 2019
This article presents hitherto unpublished correspondence of Struble in 1947 with Menger, Chandrasekhar, and eventually Einstein, about a possible observational test supporting Einstein's special relativity against Ritz's emission theory using binary stars.

The Standard-Model Extension and Tests of Relativity [PDF]

arXiv, 2006
The Standard-Model Extension, or SME, is a general framework for the study of Lorentz violation in physics. A broad variety of experiments is able to access the SME coefficient space. This proceedings briefly summarizes theory and experiments aimed at testing Special Relativity by measuring these coefficients.

Foundations of a Universal Theory of Relativity [PDF]

arXiv, 2005
Earlier, we had presented \cite{heuristic} heuristic arguments to show that a {\em natural unification} of the ideas of the quantum theory and those underlying the general principle of relativity is achievable by way of the measure theory and the theory of dynamical systems.

A Lorentz variant theory that passes fundamental tests of special relativity and makes diverging, testable but as of yet untested predictions [version 2; peer review: 2 approved]

F1000Research
Background Tests of special relativity have been conducted over the past century with increasing accuracy and none have showed violations of Lorentz invariance.

Analysis of the Capability and Limitations of Relativistic Gravity Measurements Using Radio Astronomy Methods [PDF]

The uses of radar observations of planets and very-long-baseline radio interferometric observations of extragalactic objects to test theories of gravitation are described in detail with special emphasis on sources of error.

Gravitation in Flat Spacetime [PDF]

arXiv, 2000
A special-relativistic scalar-vector theory of gravitation is presented which mimics an important class of solutions of Einstein's gravitational field equations. The theory includes solutions equivalent to Schwarzschild, Kerr, Reissner-Nordstroem, and Friedman metrics as well as to gravitational waves.

Observers' measurements in premetric electrodynamics I: Time and radar length

, 2018
The description of an observer's measurement in general relativity and the standard model of particle physics is closely related to the spacetime metric. In order to understand and interpret measurements, which test the metric structure of the spacetime,
