While most people assume their height remains constant, science shows that due to gravity, humans can become 1–2 centimeters shorter by the end of the day. But in space, the effect is far more ...

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 ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

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 ...

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 ...

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 ...
