One hundred years ago this Wednesday, Albert Einstein gave the last of a series of presentations to the Prussian Academy of Sciences, which marks the official completion of his General Theory of ...

“The one sentence statement of general relativity is that ‘gravity is the curvature of spacetime,’” explains Dr. Sean Carroll, assistant professor of physics at the University of Chicago. “Really, the ...

Albert Einstein's general theory of relativity describes gravity as the warping of space-time geometry by mass, a concept distinct from Isaac Newton's absolute space and time, and has been empirically ...

A century ago, Albert Einstein became famous. Sure, he was already well-known among physicists. But the world at large learned his name only after November 1919, when news broke that his theory of ...

This is the second of a three-part series examining the history, science and implications of Einstein’s general theory of relativity. Part one was published December 7. “The views of space and time ...

It is even possible to fit a warp drive within the equations of Einstein-and still make it practically unavailable. Over ...

“The main idea is to have a gravity gauge theory with a symmetry that is similar to the Standard Model symmetries, instead of basing the theory on the very different kind of spacetime symmetry of ...

A framework that relies on college-level mathematics could describe what happens to particles in so-called spacetime rips, gravity fluctuations such as those that occur during the birth of a black ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.
