Two black holes in deep space. (The SXS [Simulating eXtreme Spacetimes] Project via LIGO/Caltech) (CN) — A merger of two black holes “ring” in the cosmos, producing ripples in the spacetime continuum, ...

THE question whether there exists in relativity mechanics a theorem analogous to the classical law for the motion of the mass centre (conservation of total momentum) has, as far as we can see, never ...

An illustration of what a black hole with an accretion disk may look like based on modern understanding. The extreme gravitational fields create huge distortions in the hot matter and gas rotating ...

Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...
