Physicists have long assumed that the universe is pretty much the same in any direction, and now they've found a new way to test that hypothesis: by examining the shadow of a black hole. If that ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm ...

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 ...

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 ...

If there's one thing everybody knows about space, it's that there's no gravity once you leave the Earth's atmosphere. We all know that don't we? It's actually not true — and an attempt at a massive ...

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 ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...
