Dark Matter may very well be a Dead End. It was worth pursuing as hard science, but like String Theory isn’t working out so well. Time for some different approaches.
And thanks for mentioning the “light mid flight” notion. I’m surprised how few “young Earth” types have considered it, and how many (when presented therewith) don’t grasp the absurd consequences.
Dark Matter = The ‘Epicycles’ of old. Might be a useful mathematical plug in in some situations, but does not describe reality. I think somewhere cosmology took a real wrong turn. Lots of it seems like assumptions built on assumptions, ad infinitum. Even if all of these assumptions have a 95% probability of being correct, when enough are strung together, the chance of a correct end result becomes nil.
