A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

Though spacecraft with artificial gravity are still a distant dream, we had proof of concept way back in September 1966.

Researchers have demonstrated that pairs of helium atoms can exist in two places at once while remaining linked in motion by ...

Scientists show helium atoms can exist in two places at once, preserving quantum behavior even as they fall under gravity.

The first planned artificial gravity experiment took place in late 1966, but the first human on the Moon beat them to it.

A paper published in General Relativity and Gravitation proposes that black holes in a seven-dimensional spacetime do not ...
