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

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

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 ...

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 ...

Defy gravity with this fun experiment using only a plastic bottle, a ping pong ball, and water. PLEASE follow these safety precautions when doing any science experiment. • ALWAYS have an adult present ...
