A Single, ‘Naked’ Black Hole Rewrites the History of the Universe
...of the galaxy formation process, which did not start with black holes. Black holes were thought to have come along only after a galaxy’s stars gravitationally collapsed into black holes...
Physicists Identify the Engine Powering Black Hole Energy Beams
Supermassive black holes emit jets of white-hot plasma that stretch thousands of light-years across the cosmos. For the first time, researchers have identified what’s creating these jets. Paradoxically, black holes,...
Mathematicians Find an Infinity of Possible Black Hole Shapes
...mass. The same holds for black holes — or, to be more precise, the event horizons of black holes — which must, according to theory, be spherically shaped in a...
Physics Nobel Awarded for Black Hole Breakthroughs
...to always question what you’re seeing.” Two decades later, there can be no more doubt about black holes and their critical role in the cosmos. What are black holes? Black...
Wormholes Untangle a Black Hole Paradox
...EPR paradox, named for its authors, Einstein, Boris Podolsky and Nathan Rosen). The other showed how two black holes could be connected through far reaches of space through “wormholes” (ER,...
Quantum Complexity Shows How to Escape Hawking’s Black Hole Paradox
...it holds for real black holes, it will conclusively answer a gauntlet of classic black hole questions, from what an astronaut would experience as she fell into a black hole...
Why Black Hole Interiors Grow (Almost) Forever
...black holes to slowly evaporate away, giving rise to the much-discussed “black hole information paradox,” which asks what happens to information that falls into black holes. Quantum mechanics says the...
New Black Hole Math Closes Cosmic Blind Spot
...black holes. The rate of change in the frequency also provides information about a black hole’s spin. Finally, the amplitude (or height) of the detected wave can reveal how far...
This Physicist Discovered an Escape From Hawking’s Black Hole Paradox
...to particles near a black hole’s periphery, and saw unitarity break down. So do evaporating black holes really destroy information, meaning unitarity is not a true principle of nature? Or...
