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 ...

Astronomers have long described black holes as cosmic traps so powerful that nothing — not even a beam of light — can claw its way free. Yet even these extreme objects have limits, and scientists say ...

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 variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

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 ...

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 ...

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 ...
