A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers aren’t so sure.

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

While this may complicate the quest for a clear experimental signature of quantum gravity, it does not render such tests useless. According to the research team, both classical and quantum models of ...

“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 ...

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 ...

The possibility that our entire universe merely exists inside a computer simulation is more than an idle science fiction ...

For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Quantum gravity strives to reconcile the seemingly disparate realms of general relativity and quantum mechanics. Central to this endeavour is the realisation that classical concepts of spacetime may ...

Physicist Mir Faizal, Adjunct Professor with UBC Okanagan’s Irving K. Barber Faculty of Science, was not out to shatter the ...

Evidence of this quantum layer may be coming soon. Here’s what you’ll learn in this story: Physicists are still puzzling over ...

A century since Werner Heisenberg changed the course of physics, five of the world’s leading physicists examine the greatest achievements of quantum mechanics and look forward to the next 100 years, ...
