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

A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

Black holes form when an enormous mass collapses into an infinitesimal point known as a singularity. That compression creates such powerful gravity that nearby matter, particles and even photons are ...

Bottom line: For decades, physicists have been trying to solve one of the greatest mysteries in science: how gravity operates at the smallest scales governed by quantum mechanics. While we have ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential “cosmic glitch” in the universe’s gravity, explaining its strange behaviour on a ...

His theory of supergravity sought to bridge quantum mechanics and general relativity, a potential step toward a theory of everything. By Kenneth Chang Stanley Deser, a theoretical physicist who helped ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...
