A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

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, ...

Pete Wilda, a Fairbanks reader of this column, wanted to know how the snow here can bend off railings and loop from power lines without breaking. He grew up in eastern Wisconsin and doesn’t remember ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

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 ...

An ancient spear-throwing tool enabled prehistoric hunters to boost the distance they could launch a feathered projectile – but the unexpected negative effects of gravity on the tool may explain why ...
