Somewhere between an electron and a human being, the rules of physics change. Quantum mechanics allows an atom to exist in two states simultaneously — spinning left and right at the same time, for ...

Scientists have tested gravity across some of the largest structures in the universe and found that it behaves exactly as predicted by long-standing physical laws. Researchers led by University of ...

Gravity has passed nearly every test physicists have thrown at it for a century. Yet on the largest scales in the universe, a small mismatch may be pointing toward a limit in Einstein’s theory. A team ...

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 ...

A researcher from Sejong University has used a new theory of gravity proposed by Erik Verlinde to predict the observed ...

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 ...
