Black holes

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.

Two independent papers vanquish lingering doubts about LIGO’s historic discovery of gravitational waves.

The renowned physicist Leonard Susskind has identified a possible quantum origin for the ever-growing volume of black holes.

Quasars powered by supermassive black holes have been unexpectedly vanishing. Scientists have started to figure out why.

In the latest campaign to reconcile Einstein’s theory of gravity with quantum mechanics, many physicists are studying how a higher dimensional space that includes gravity arises like a hologram from a lower dimensional particle theory.

Hot spots have been discovered orbiting just outside the supermassive black hole at the galaxy’s center. Their motions have given us the closest look at that violent environment.

Computer simulations and custom-built quantum analogues are changing what it means to search for the laws of nature.

String theorists elide a paradox about black holes by extinguishing the walls of fire feared to surround them.

Black holes occasionally reveal themselves when passing stars get ripped apart by their gravity. These tidal disruption events have created a new way for astronomers to map the hidden cosmos.
