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 behavior on a ...

Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively ...

Physicists have found a new mathematical way to connect Einstein’s description of gravity with ideas from quantum physics.

We can model the motions of planets in the Solar System quite accurately using Newton’s laws of physics. But in the early 1970s, scientists noticed that this didn’t work for disc galaxies – stars at ...

Gravity has passed nearly every test physicists have thrown at it for a century. Yet on the largest scales in the universe, a small mismatch may be pointing toward a limit in Einstein’s theory. A team ...
