What this episode covers
Neutron stars are weird — big balls of super-dense, stupidly energetic, rapidly rotating nuclear splodge. They're stars that, after running out of fusion fuel, have collapsed beyond the Quantum Electron Squashing Limit (a real thing), and have entered the Quantum Neutron Squooshing Regime (also a real thing). But there's a limit to how big they can be ... and, in an amazing series of coincidences, astronomers have just found a neutron star so close to that limit, it makes us wonder if something weird's going on.
