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

Some of the first experiments in space dealt with gravity and weightlessness. They were somewhat simple studies to test the new environment. Alan Shepard was the first man to hit a golf ball on the ...

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

Purdue University is expanding the scientific footprint of 2027’s all-Boilermaker suborbital flight mission with the addition ...

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

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

WEST LAFAYETTE, Ind. — After a decade of preparation and two years of active experiments in space, a facility that Purdue University and NASA’s Glenn Research Center in Cleveland designed, built and ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

GALVESTON, Texas — When the Apollo 11 crew got back from the moon 40 years ago this week, they showed no ill effects from seven days spent in weightlessness. But as American astronauts and Soviet ...

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...
