WebMay 6, 2024 · The x-t components of the stress-energy tensor flip their signs under a parity inversion, so they have to vanish for an isotropic photon gas. They don't vanish for a wave propagating in a certain direction.

WebNov 30, 2024 · Noether's first and second theorems both imply conserved currents that can be identified as an energy-momentum tensor (EMT). The first theorem identifies the EMT as the conserved current associated with global spacetime translations, while the second theorem identifies it as a conserved current associated with local spacetime translations. http://galileo.phys.virginia.edu/classes/524/524l06.pdf Webenergy-momentum tensors Tµwe will typically encounter in cosmology.
