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

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 ...

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 ...

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.

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 ...

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 ...

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

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 ...

Good science communication is not just about explaining your work. As Brian Clegg argues, it’s about being able to put yourself in a non-scientist’s shoes to anticipate the kind of questions they will ...
