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 ...

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

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.

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 ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

Quantum theory and general relativity will only be unified when theory meets experiment Physics in the 20th century was built on two great revolutions: the general theory of relativity and quantum ...
