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 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 ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Researchers in Germany argue that a modified theory of gravity could explain universal expansion, removing dark energy from ...

A recent study has investigated teleparallel gravity and its potential to resolve tension surrounding the expansion of the universe in a way that general relativity can't. In the early 20th century, ...

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 ...

Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...
