Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.

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.

Gravity is a basic force that affects everything we experience. Watch as a flat earther attempts to explain it without using ...

A new gravitational model suggests dark matter may not exist. By allowing gravity to weaken more slowly at large distances, physicist Naman Kumar shows galaxy rotation curves can be explained using ...

Isaac Newton formulated his theory of gravity as an action at a distance: a planet instantly feels the influence of another celestial body, no matter the distance between them. This characteristic ...

Spacecrafts don’t just rely on rockets—they use planets to pick up speed! Spacecrafts don’t just rely on rockets—they use planets to pick up speed! It’s called a gravity assist, and it’s one of the ...
