The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

Physicists from Swansea University have played the leading role in a scientific breakthrough at CERN, developing an ...

“We showed that if black hole morsels are created during mergers, they would produce a burst of high-energy gamma rays, with the delay time related to their mass,” Dr. Cacciapaglia said. “Our analysis ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

A tool called AI-Newton can derive scientific laws from raw data, but is some way from developing human-like reasoning.

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the ...
