At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

Black holes, these extreme cosmic entities, might well hold the missing clues to solve one of physics' greatest mysteries: ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

By using light to emulate the structure of space-time, researchers can better understand black holes – and the exotic objects ...

In our work, we discovered a quantum Penrose inequality that applies to all known examples of quantum black holes, even in the presence of strong quantum effects. The quantum Penrose inequality limits ...

"In quantum mechanics, time as we understand it cannot end as systems perpetually change and evolve." The scientists' ...

Scientists created a giant vortex made of tiny quantum pieces to bring black hole physics down to Earth. Comments (1) When you purchase through links on our site, we may earn an affiliate commission.

Any quantum experiment done near a black hole could set up a paradox, the researchers find, in which the black hole reveals information about its interior — something physics says is forbidden.

Rather than using a “top-down” approach to quantize general relativity they instead consider the effects of a black hole’s quantum state on the behaviour of a specific physical device called an ...

Alternative black hole models incorporating quantum effects suggest singularities may not be necessary, proposing regular black holes and mimickers without central singularities.

When they are included, scientists call the black holes “quantum black holes”. These have long provided a further mystery, as we don’t know how Penrose’s conjecture works in the quantum realm.
