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 ...

A view of the central region of the Perseus galaxy cluster, one of the most massive objects in the universe, shows the ...

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, ...

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 ...

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 ...
