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.

Boosting one term in a complex equation helps scientists explain how the results could change. Scientists in Greece have laid ...

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 Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole.

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 ...

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 ...

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 ...

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 ...

I knew, before I went to see “Gravity” that the filmmakers took a few liberties with the science. I’d read a New York Times story explaining that they conveniently placed the Hubble Telescope, the ...
