Debate Erupts Over How ‘Forbidden’ Black Holes Grow
Once missing in action, middleweight black holes have finally been detected. Now researchers are trying to figure out how they grow from small ones.
The Most Famous Paradox in Physics Nears Its End
In a landmark series of calculations, physicists have proved that black holes can shed information.
Physics Nobel Awarded for Black Hole Breakthroughs
Roger Penrose, Reinhard Genzel and Andrea Ghez were awarded the Nobel Prize in Physics for their studies of black holes.
Physicists Argue That Black Holes From the Big Bang Could Be the Dark Matter
It was an old idea of Stephen Hawking’s: Unseen “primordial” black holes might be the hidden dark matter. A new series of studies has shown how the theory can work.
The Physicist Who Slayed Gravity’s Ghosts
Claudia de Rham showed how theories of “massive gravity” could potentially get rid of the need for dark energy.
Spotting Quantum Black Holes in the Lab
Can we test speculations about how quantum physics affects black holes and the Big Bang?
Why Gravity Is Not Like the Other Forces
We asked four physicists why gravity stands out among the forces of nature. We got four different answers.
Black Hole Paradoxes Reveal a Fundamental Link Between Energy and Order
By chewing on the problems posed by “extremal” black holes, physicists have exposed a surprising and universal connection between energy and entropy.
