Theorem of Conservation of Angular Momentum

Every continuous symmetry of the legrangon, which describes the motion and interaction of particles, leads to a conservation law. If momentum really is conserved everywhere in the universe, it tells you there's no different place in space. Rotational velocity is important. And so we have conservation of angular momentum because the universe can be rotated through an arbitrary angle and nothing changes. It's not just the equations. It's like the universe, man, the universe. Man.
