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.
New Math Proves That a Special Kind of Space-Time Is Unstable
Einstein’s equations describe three canonical configurations of space-time. Now one of these three — important in the study of quantum gravity — has been shown to be inherently unstable.
Why Are Black Holes So Bright?
And why is the black hole at the center of our own galaxy so dim?
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.
