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 ...

Here’s what you’ll learn when you read this story. A conspiracy theory that spread on social media claims that gravity will disappear for seven seconds this August, and that NASA is aware that this ...

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 ...

If you want to understand gravity, it makes sense to study black holes. Nowhere else can you find so much gravity so conveniently compacted into such a relatively small space. In a way, in fact, black ...

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 the April 1981 issue of Popular Science, we explored the many initiatives and techniques used in the exciting hunt for sensing gravity waves, then out of reach. By Bill Gourgey Published May 18, ...
