General Relativistic Hydrodynamics in Discrete Spacetime
- Smaug123 3y agoI haven't read this yet (and my GR chops are almost certainly not good enough), but Gorard claims that the Wolfram model of physics may make predictions about material accretion around a spinning black hole. Discovered from Gorard's tweet https://twitter.com/getjonwithit/status/1754678751403589770 https://twitter.com/getjonwithit/status/1754678751403589770 > Featuring a tentative(!) astrophysical prediction: rapidly-spinning black holes in discrete spacetimes accrete material slowly and more unstably than in continuous ones. And perhaps we might be able to observe that...
