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. Identical twins have nothing on black holes. Twins...
‘Unicorn’ Discovery Points to a New Population of Black Holes
Small black holes were nowhere to be found, leading astronomers to wonder if they didn’t exist at all. Now a series of findings, including a “unicorn” black hole, has raised...
Black Holes Will Eventually Destroy All Quantum States, Researchers Argue
...like somehow it’s deep.” Black Holes and Superpositions To understand how a black hole could observe the universe, start small. Consider the classic double-slit experiment, in which quantum particles are...
Hologram Within a Hologram Hints at Fate of Black Holes
...to the question of what happens to a 2D black hole’s information. Most experts assume that if the reasoning is correct, it should carry over to higher-dimensional black holes like...
Big Black Holes Found in the Smallest Galaxies
...holes in the universe came to exist. Many astrophysicists, including Bellovary, think that such supermassive black holes grow when entire galaxies smash into each other, leading their central black holes...
At Long Last, Mathematical Proof That Black Holes Are Stable
...Kerr, are stationary, Giorgi said. “These formulas apply to black holes that are just sitting there and never change; those aren’t the black holes we see in nature.” To assess...
She Turns Fluids Into ‘Black Holes’ and ‘Inflating Universes’
...black holes in “a giant bathtub, but it’s a very special one.” Weinfurtner meets with graduate students in her office. The fluid analogue of a black hole forms as water...
Why Are Black Holes So Bright?
...Why Black Holes Are So Bright There are a number of ways that black holes can appear to glow. When gas from nearby stars falls toward the black hole, the...
Massive Black Holes Shown to Act Like Quantum Particles
Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave. When...
