Nobody really understands gravity. We know what it does. We have equations for it, and we're constantly correcting GPS ...

In a bold step toward solving one of science's most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Gravity is the force with which we’re most familiar. It’s what’s keeping you on the planet, even as you’re reading this.

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

Gravity can turn itself into light, but only if space-time behaves in just the right way, a research team has found. Under normal circumstances, you cannot get something from nothing. Specifically, ...

There’s a new equation floating around the world of physics these days that would make Einstein proud. It’s pretty easy to remember: ER=EPR. You might suspect that to make this equation work, P must ...

Despite decades of searching, the "dark matter" thought to hold galaxies together is still nowhere to be found. Matthew Chalmers describes how some physicists think it makes more sense to change our ...
