Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

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 ...

Zero gravity, often depicted in science fiction and space documentaries, is a fascinating concept that sparks curiosity and wonder. Commonly misunderstood, zero gravity is not the absence of gravity ...

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 ...

Heading into space means leaving Earth's gravity behind. Astronauts floating around on the International Space Station might look like they're having fun in the weightless environment, but a lack of ...

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 ...

Alex Chadwick talks Ira Flatow, host of NPR's Talk of the Nation Science Friday, about new examinations of the theories of Galileo and Isaac Newton relating to gravity. This is DAY TO DAY. I'm Alex ...

Sinlaku rapidly intensified over the ocean before its impacts reached land. Around the time of this strengthening, satellites ...

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, ...
