The energy and momentum of a closed system is always conserved.
If a laser can emit perfectly parallel and perfectly superimposed light waves (occupy the exact same space) that are perfectly 180° out of phase and of the same frequency, what can be said about the energy and momentum of the emited light waves? If they will never ever diverge, are they not forever beyond the possibility of observation and indistinguishable from undisturbed space?
If this correct, is energy and momentum still conserved but technically unobservable?
Would they still contribute to the stress-energy tensor of their position in space according to general relativity?
