A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

“We proved that the Einstein field equation from general relativity is actually a relativistic quantum mechanical equation,” the researchers note in their study.

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

Earlier this year, new research suggested a potential solution to one of the most troubling aspects of modern physics — that "singularities" seem to exist at the hearts of black holes. The idea of the ...

Mathematical equations, from the formulas of special and general relativity, to the Pythagorean theorem, are both powerful and pleasing in their beauty to many scientists. Here are experts ...

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another.

Dirac equation: A relativistic wave equation that describes spin-½ particles and integrates the principles of quantum mechanics with special relativity.

General Relativity was established in 1915 by Albert Einstein and the first solutions to the Einstein equation were found already in early 1916. Is general relativity proven?
