Research on warp drive has moved from a discussion of impossible ingredients to a problem of measurable geometry. A new theoretical approach by researchers affiliated with the University of Alabama in ...

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 ...

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 ...

“What would it take for ‘warp drive’ to stop meaning a screenplay shortcut and start meaning a solvable design problem?” In ...

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

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.

Perhaps you’ve noticed all the fuss this week over Albert Einstein and his famous general theory of relativity, which turned 100 years old. Who better to give you a glimpse into what the theory is all ...
