Thanks for the replies, sorry took a while to comment. Yeah that's some weird stuff, I'm not sure I'm any closer to intuitive understanding of torque.

Another, completely unrelated, thing. Ever since years ago watching some documentary about the scale of atoms, the relative distance between electrons and the nuclei, I've been wondering about this but never been able to find any explanation that I could understand. If you exert enough outside pressure to the electrons to squeeze them into the nucleus you're breaking the electron degenerative pressure, and if you have enough mass together in practise this is what happens when a star collapses into a white dwarf, right? If then you keep applying more force, enough to force the electrons and protons to combine and create neutrons (the Chandrasekhar limit?), you're left with a neutron star? Still not satisfied, you keep exerting more force (and adding mass) to collapse the neutrons (the Tolman–Oppenheimer–Volkoff limit?) you end up with a black hole or something silly like a quark star?
