Mass and Angular Momentum in General Relativity [PDF]

open access: yes, 2010
We present an introduction to mass and angular momentum in General Relativity. After briefly reviewing energy-momentum for matter fields, first in the flat Minkowski case (Special Relativity) and then in curved spacetimes with or without symmetries, we ...

Linear Regression under Special Relativity [PDF]

open access: yesarXiv, 2020
This study investigated the problem posed by using ordinary least squares (OLS) to estimate parameters of simple linear regression under a specific context of special relativity, where an independent variable is restricted to an open interval, (-c, c).

Tests of General Relativity on Astrophysical Scales [PDF]

open access: yes, 2009
While tested to a high level of accuracy in the Solar system, general relativity is under the spotlight of both theoreticians and observers on larger scales, mainly because of the need to introduce dark matter and dark energy in the cosmological model. This text reviews the main tests of general relativity focusing on the large scale structure and more

The challenge of changing deeply-held student beliefs about the relativity of simultaneity [PDF]

open access: yes, 2002
Previous research indicates that after standard instruction students at all academic levels often construct a conceptual framework in which the ideas of absolute simultaneity and the relativity of simultaneity co-exist.

Ontology of the Theory of Relativity [PDF]

open access: yesarXiv, 2023
Both relativistic mechanics and Newtonian mechanics are based on principles that have ontological implications. We propose a series of formalisms that rigorously define the ontology underlying mechanical theories, in order to clarify and formally establish the ontology of the physics of motion.

Experiment for Testing Special Relativity Theory [PDF]

open access: yesPhys.Atom.Nucl.72:561-566,2009, 2009
An experiment aimed at testing special relativity via a comparison of the velocity of a non matter particle (annihilation photon) with the velocity of the matter particle (Compton electron) produced by the second annihilation photon from the decay Na-22(beta^+)Ne-22 is proposed.

LARES a new satellite specifically designed for testing general relativity [PDF]

open access: yes, 2015
It is estimated that today several hundred operational satellites are orbiting Earth while many more either already re-entered the atmosphere or are no longer operational.

Snyder's Model -- de Sitter Special Relativity Duality and de Sitter Gravity [PDF]

open access: yes, 2007
Between Snyder's quantized space-time model in de Sitter space of momenta and the \dS special relativity on \dS-spacetime of radius $R$ with Beltrami coordinates, there is a one-to-one dual correspondence supported by a minimum uncertainty-like argument.

Testing numerical relativity with the shifted gauge wave

open access: yes, 2005
Computational methods are essential to provide waveforms from coalescing black holes, which are expected to produce strong signals for the gravitational wave observatories being developed.
