The “gravitational memory effect” predicts that a passing gravitational wave should forever alter the structure of space-time. Physicists have linked the phenomenon to fundamental cosmic symmetries and a potential solution to the black hole information paradox.

The five-decade-old paradox — long thought key to linking quantum theory with Einstein’s theory of gravity — is falling to a new generation of thinkers. Netta Engelhardt is leading the way.

A new study shows that extreme black holes could break the famous “no-hair” theorem, and in a way that we could detect.

Featuring paradoxical black holes, room-temperature superconductors and a new escape from the prison of time.

In a landmark series of calculations, physicists have proved that black holes can shed information.

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

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

Calculations involving a higher dimension are guiding physicists toward a misstep in Stephen Hawking’s legendary black hole analysis.

Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.
