- Deviations of conservation laws in the context of cosmological evolution?
If energy is "not conserved" in General Relativity (or at least, it is difficult to define it) in the context of an expanding accelerating spacetime (like it happens in our Universe), are there any observations of deviations from the strict conservation laws in the evolution and formation of large scale structures (like clusters or superclusters of galaxies for instance)?
For example, in some articles about the study of galaxies and clusters evolutions and formations, sometimes the effects of the "tidal force" from spacetime expansion is considered... Has the expansion changed the energy or momentum of these systems somehow?
