You may be right, but I think referring to this perspective as “Crackpot stuff” is entirely too strong a criticism. Wormholes and flying cars are “crackpot stuff.” But regarding this question it feels like you are reaching for the strongest possible language to rebut a position you simply disagree with. We really are in a moment where serious astronomers and astrophysicists are evaluating validity and correctness of some of our most fundamental assumptions about the universe, to a degree that we simply haven’t seen since at least the mapping of the CMB, and perhaps longer.
