I've read that GR is diffeomorphism invariant, I asked a math buddy of mine and I have a VERY BASIC idea of what that means in this case - the theory is the same regardless of your choice of coordinates?(adsbygoogle = window.adsbygoogle || []).push({});

Noether's theorem states that for every symmetry there's a corresponding conservation law. Would diffeomorphism invariance count as a symmetry in this case and what would be the conserved quantity? Would it just be mass-energy?
