Black Holes Will Eventually Destroy All Quantum States, Researchers Argue
New calculations suggest that the event horizons around black holes will ‘decohere’ quantum possibilities — even those that are far away.
Physicists Create a Holographic Wormhole Using a Quantum Computer
The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.
Gravitational Waves Should Permanently Distort Space-Time
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.
This Physicist Discovered an Escape From Hawking’s Black Hole 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.
In Violation of Einstein, Black Holes Might Have ‘Hair’
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.
The Most Famous Paradox in Physics Nears Its End
In a landmark series of calculations, physicists have proved that black holes can shed information.
Spotting Quantum Black Holes in the Lab
Can we test speculations about how quantum physics affects black holes and the Big Bang?
Wormholes Reveal a Way to Manipulate Black Hole Information in the Lab
A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.
