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 ...

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

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 ...

Something is seriously wrong with gravity, and nobody's quite sure why. The problem is that gravity is too weak. Out of the four fundamental physical forces in the universe—gravity, electromagnetism, ...

One of the greatest unsolved puzzles in all of science is dark energy. The Universe isn't just expanding, but the expansion rate that we infer for distant galaxies is accelerating: their recession ...
