I'm well aware of relativity. But I don't see how you can invoke it when
discussing all possible, i.e. non-contradictory, universes. Neither do I see
that list of states universes would be a teeny subset of all mathematically
consistent universes. On the contrary, it would be very large. It would
certainly be much larger than that teeny subset obeying general relativity or
Newtonian physics or the standard model of QFT in Minkowski spacetime.
