A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behavior on a ...

The Sun is not nailed to the center of the solar system. It moves, wobbles, and traces a small loop through space, tugged by the combined gravity of every planet in orbit around it. Yet the whole ...

Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all. Instead, it could arise from entropy, a measure of disorder. The theory, ...

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 ...
