Poincaré symmetry — the group that feeds Noether
relativity
The symmetry group of relativity - boosts, rotations and translations - is a continuous symmetry, so by Noether it gives the conserved energy, momentum, angular momentum and the stress-energy tensor. The symmetry of spacetime is the source of the conservation laws.

- part of → Relativity — many frames, one invariant — a pillar of relativity (Poincaré symmetry)
- connects at → Noether's theorem — symmetry is the source of conservation — the Poincare symmetry group -> conserved energy, momentum, angular momentum, via Noether
