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, ...

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 ...

A new theory of gravity might explain the curious motions of stars in galaxies. Emergent gravity, as the new theory is called, predicts the exact same deviation of motions that is usually explained by ...

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 ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

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 ...
