black holes

Claudia de Rham showed how theories of “massive gravity” could potentially get rid of the need for dark energy.

Can we test speculations about how quantum physics affects black holes and the Big Bang?

We asked four physicists why gravity stands out among the forces of nature. We got four different answers.

By chewing on the problems posed by “extremal” black holes, physicists have exposed a surprising and universal connection between energy and entropy.

Einstein’s equations describe three canonical configurations of space-time. Now one of these three — important in the study of quantum gravity — has been shown to be inherently unstable.

And why is the black hole at the center of our own galaxy so dim?

A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.

After a space telescope disintegrated, astrophysicists had little hope of understanding how supermassive black holes agitate giant galaxies. Then they invented a hack.

For the first time, physicists have calculated exactly what kind of singularity lies at the center of a realistic black hole.
