Warp drive has quietly shifted from pure fantasy to a live topic in serious physics, with new models showing how spacetime ...

Warp drive has long lived in the realm of starships and scriptwriters, but the equations behind it are starting to look less ...

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 ...

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 ...

The lecture will be held virtually. To inscribe into the learnweb course please send an e-mail to (heitger at uni-muenster dot de) or (raimar at math dot uni-muenster dot de). General Relativity: ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

Strangely, although we feel as if we sweep through time on the knife-edge between the fixed past and the open future, that edge—the present—appears nowhere in the existing laws of physics. In Albert ...

General Theory of Relativity: brief recap of special relativity, equivalence principle, semi-Riemannian geometry, Einstein's field equations, Schwarzschild solution and implications (perihelion shift, ...
