Discover 25 mind bending facts about gravity that will stun you! From everyday wonders to cosmic mysteries, explore how ...

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 ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

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

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 ...

Scientists are a step closer to unraveling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force that ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

A clear look at how physics defines gravity, from Newton’s force-based model to Einstein’s view of curved spacetime, and why the distinction matters in modern science.

The physicist and bestselling author on the radical politics and drugs of his youth, his life’s work and why we all need a break ...

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, ...
