Astrophysicists have observed puzzling behavior in star clusters that defies our current understanding of gravity at cosmic scales. Intriguingly, the observations fit with an alternative theory of ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Solving Einstein's equations by using quantities that apply across all space and time coordinates could enable physicists to eventually find their 'white whale': a quantum theory of gravity. In ...

Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale. A group of researchers at the University of Waterloo and the ...

Are we living in “The Matrix” in real life? In the 1999 science-fiction film, Neo discovers that the universe is a simulation — but one scientist believes that the idea isn’t all fiction. Dr. Melvin ...

AUSTIN (KXAN) — A ‘gravity hole’ on Earth? Earlier this summer, researchers with the Indian Institute of Science published a paper exploring one of these ‘gravity holes’. Found all over the planet, ...
