If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

A new recipe for black holes could do away with central singularities, saving the laws of physics from troubling infinities.

A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum ...

Since the beginning of the 20th century, Einstein's theory of general relativity has been the best description we have of how gravity works. However, right around when Einstein came up with ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Miguel Alcubierre was able to construct a valid solution to the equations of general relativity that enable a warp drive. But ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

While quantum mechanics governs the behavior of particles at the smallest scales, general relativity describes the force of gravity on cosmic scales. Unifying these two frameworks has been one of ...

Gravitons are hypothetical subatomic particles, considered key components in a theoretical quantum theory of gravity. Some ...
