As matter becomes more and more dense, that effect becomes more pronounced. Black holes create a gravity well so deep that there's a threshold around black holes called an event horizon ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, scientists could reveal hidden asymmetries in the universe.

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as ...

Unlike previous models, which required exotic matter, this new study reveals that pure gravity -- without additional matter fields -- can generate regular black holes without singularities.
