Fundamental physics faces a stubborn paradox: the current impossibility of reconciling the rules of the quantum world with those of gravity, despite a century of efforts. This theoretical ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. The idea of gravity as we know it has been around for a long time ...

In 1916, Albert Einstein predicted the existence of gravitational waves when he proposed his theory of general relativity. Einstein figured that any object with mass creates a kind of signal, rippling ...

In 1915, the universe was small and static. Space was smooth. Gravity pulled things to the ground. At least that’s the way it was in the minds of all but one exceptional physicist — Albert Einstein.

What could be more familiar than gravity? Drop something and gravity pulls it to the floor, right? And in school we learn that gravity is what guides the moon in orbit around Earth, and Earth in its ...
