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.

Fundamental physics faces a stubborn paradox: the current impossibility of reconciling the rules of the quantum world with ...

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 ...

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of ...

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 ...

Ghostly particles could be haunting our universe. A new theory claims that the cosmos is full of unseen particle families that don’t interact with each other. If true, the model could explain why ...

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 ...

The Big Bang purportedly transpired 13.8 billion years ago, and even so, the universe continues to expand even today. But if that thought alone wasn’t impressive enough, scientists also believe that ...
