At present, mainstream physicists seem to have fully accepted Einstein's Special Theory of Relativity (STR) and to take it as the foundation of modern physics because the theory appears perfectly ...

(Phys.org)—Possibly the most well-known consequence of Einstein's theory of special relativity is that nothing can travel faster than the speed of light, c. According to the mass-energy equivalence ...

Presenting a new perturbative method to deal with the gravitational N-body problem in general relativity. A novel approach to construct global and local reference frames leads to explicit ...

A theory developed by Albert Einstein stating that the laws of motion are the same for all inertial (non-accelerating) frames of reference and that the speed of light (in a vacuum) is the same for all ...
