Warp drive has long been shorthand for “pure fantasy,” a narrative device that lets starships hop between stars without ...

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

General Relativity reinterprets the force of gravity not as a traditional force but as a manifestation of the curvature of spacetime. Its formulation rests on a rigorous mathematical framework built ...

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: ...

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 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 ...

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 ...

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