Black holes exist in our universe. That’s widely accepted today. Physicists have detected the X-rays emitted when black holes feed, analyzed the gravitational waves from black hole collisions and even ...

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 ...

At the frontiers of theoretical physics, many of the most popular ideas have one thing in common: they begin from a mathematical framework that seeks to explain more things than our currently ...

Dark energy, making up 70% of the universe, causes its accelerating expansion. Gravitational waves, predicted by Einstein, were detected from colliding black holes. The Event Horizon Telescope imaged ...

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 ...

I’ve been getting lots of emails and tweets about a young man named Jacob Barnett, a 12-year-old who is apparently a math genius. He’s been getting a lot of press lately because he’s tackling some ...

In this paper-covered pamphlet of eighty pages, which is sold for saxpence, Prof. Rice sets forth the doctrine of relativity: and not only this, but also (as prelimiriaries to it) the principles of ...

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: ...
