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.
Astronomers Find Black Holes Stirring Up the Biggest Galaxies
After a space telescope disintegrated, astrophysicists had little hope of understanding how supermassive black holes agitate giant galaxies. Then they invented a hack.
Black Hole Singularities Are as Inescapable as Expected
For the first time, physicists have calculated exactly what kind of singularity lies at the center of a realistic black hole.
Hologram Within a Hologram Hints at Fate of Black Holes
Calculations involving a higher dimension are guiding physicists toward a misstep in Stephen Hawking’s legendary black hole analysis.
Are We All Wrong About Black Holes?
Since the 1970s, physicists have described black holes using borrowed versions of the laws of thermodynamics. But are black holes really thermodynamic systems? Craig Callender worries that the analogy has been stretched too far.
A Black Hole So Big It ‘Should Not Exist’
Researchers have confirmed rumors of a black hole collision that challenges our ideas about how black holes form.
To Make Two Black Holes Collide, Try Three
How do black holes merge and make gravitational waves? Maybe with a little help from their friends.
Big Black Holes Found in the Smallest Galaxies
Tiny, dim “dwarf” galaxies have been found to hide gas-spewing black holes.
Philosophers Debate New ‘Sonic Black Hole’ Discovery
Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.
