After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest numbers to nail down.

A 10-year effort to measure gravity, a fundamental force in the universe, has failed to come up with a conclusive answer.

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 ...

As far as we know, our physical world is governed by four fundamental forces: electromagnetism, weak and strong nuclear forces, and gravity. Apart from playing with bar magnets or marveling at the ...

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 ...
