Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all.

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

Satellites detected a mysterious gravitational change beneath Earth's surface, suggesting rapid movement of interior masses.

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

A scientist from Tokyo Metropolitan University has solved the longstanding problem of a "dissonance" in gravitational waves emitted by a black hole. Using high precision computing and a new ...

Our universe would look so different, Kyle. You might not recognize it even if you could be here to see it. Unfortunately, there probably wouldn’t be a whole lot to see. I learned about this from ...

The universe is expanding—that much is clear. The rate at which it expands is a bone of contention among scientists. The so-called Hubble constant accurately predicts how fast objects recede, but it's ...
