In the search for a theory that unites general relativity and quantum physics, many have tried to rethink space-time. But what if space-time emerges naturally, like a hologram?

Physicists have simulated strange objects from string theory to determine what they look like – if they exist, they could be mistaken for a black hole when imaged from very far away

Under the laws of quantum mechanics, information about what has fallen into a black hole cannot be destroyed, and now researchers claim they have figured out how it is preserved

The first simulation of a wormhole on a quantum computer made headlines, but a new study brings into question whether it was an accurate representation

Black holes may not destroy all information about what they were originally made of, according to a new set of quantum calculations, which would solve a major physics paradox first described by Stephen Hawking

Black holes were once thought not to have pressure, but a new set of quantum calculations has found that they may have some at their edges, which was completely unexpected

Perhaps the most important problem in physics is how gravity and quantum mechanics fit together, and strange fluctuations in gravitational waves could help us figure it out

It’s the ultimate scientific quest – to understand everything that there is. But the closer we get, the further away it seems. Can we ever get to grips with the true nature of reality?

Our best models of cosmology suggest the universe will either go on forever, implode or rip itself apart. A new proposal suggests an even weirder destiny

White holes are black ones in reverse, spewing out matter– and they could give us our first glimpse of the quantum source of space-time, says physicist Carlo Rovelli
