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: ...

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...

From smashing particles together to analyzing the properties of a supermassive black hole, much of physics research takes place far beyond the realm of our everyday experience. However, there is one ...
