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

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 ...

A new gravitational theory formulated by Erik Verlinde, renowned string theory expert at the University of Amsterdam and the Delta Institute for Theoretical Physics, might just do away with the roles ...

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 ...
