At the center of each classical black hole is a paradox: a singularity, where gravity is infinite and the laws of physics break down. But a new theoretical breakthrough says such cosmic dead ends aren ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...

Quantum entanglement—once dismissed by Albert Einstein as “spooky action at a distance”—has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum ...
