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 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 ...

Einstein’s gravity-explaining theory of general relativity may not tell the complete story of how galaxies and black holes formed throughout the universe. New supercomputer simulations implementing ...

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 ...

Some questions about the universe can quickly stray away from physics and into the realms of philosophy. What was before the Big Bang? Why is there something and not nothing? Happily some of the ...

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 ...

In 1915, Albert Einstein published his pioneering theory of general relativity (GR) which beautifully describes the nature of gravity and its effect on large objects in space. Since then, this work ...

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 ...
