When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. Thanks to a global network of observatories—called the Laser Interferometer Gravitational-Wave ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

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. When you purchase through ...

Scientists have demonstrated that Einstein's theory of general relativity is correct to a remarkable degree of accuracy, despite having been around for more than a century. The team behind the ...

A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum gravity" could arise from entropy, possibly solving puzzles put forth by ...
