Scientists in Greece have laid out a mathematical framework to help explain a so-far-unsolved gap in our understanding of how ...

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 ...

Black holes form when an enormous mass collapses into an infinitesimal point known as a singularity. That compression creates ...

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

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 ...

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 ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When you look out at the Universe, there are a few things you'd ...
