That's kind of irrelevant though. You could still have a big bang, just without the CMB as it's signature. In any case the fact that modeling cosmic dust backwards through time produces a redshifted black body radiation that more or less looks like the CMB is something you can't just dismiss. Or else you're not being scientific, you're just being religious.
- SiempreViernes 3y agoIt's very much not: "modeling cosmic dust backwards through time" necessarily means you have assumed a cosmology, and in particular this result of the BB spectra from just dust absolutely needs that the cosmology is cyclic because that's the only way to get the constant densities that starts the entire derivation.
- throwawaymaths 3y agoNo, modeling cosmic dust backwards in time is just rolling back the expansion parameters that are well accepted and based on observation.
