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

The disconnect between relativity and the quantum world. Einstein’s theory of general relativity explains how gravity works. It says that massive objects like planets, stars, or galaxies bend ...

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

Murray said he preferred the special relativity equations to the more complicated formulas in Einstein's later theory. "I could never follow the maths of general relativity," he said. Euler's equation ...

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 ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light.

New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly lies at the heart of a black hole. Comments ( 0 ) () ...

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

Relativity equations account for the effects of the Earth’s gravity and the distances between the satellites and their receivers on the ground.
