Not to mention that “this isn’t how optics works!” The optical properties of a material caused by its inhomogeneity doesn’t change if you look at it from further away! I.e.: frosted glass will look frosted from any distance other than “extremely close”. The same applies to wavey or otherwise non-flat transparent or translucent materials. The same ought to apply to the lumpiness of spacetime caused by galaxies — it shouldn’t matter if you “zoom out”, the bumps and troughs are still there, bending light the same way! I thought this was obvious, it’s something that occurred to me at least a decade ago! I can’t believe astrophysicists just hand-waved this away, when it clearly can’t be ignored.
