Correct. Somehow I misread their findings. Their work predicts future confirmation with better instruments/scopes.
Yes, but like Galileo favoring the Cop model, the model makes predictions that can be tested with future observations with improved telescopes. Time will tell.
But that the CMBR is like a giant ball oh hot H and He is not accurate since it, primarily, is the photon flood that was released as if from prison that was predicted and observed. Shortly after this instant blast, which varied slightly across the smaller universe, the light passed through the gas formed. This is the clouds they mention. Thus, we should see both the light from the CMBR plus some degree of absorption lines. Their computer modeling allows them to alter the redshift, so they offer this as well. Thus, if absorption lines are eventually found, say, for z=1500, then they will earn some credit in helping create a conundrum for BBT. It’s still the safe bet for something very close to z=1100.
I think cosmologists are clear. Notice that this paper is only stating their findings, not taking sides. Or do you see it differently?
Given the plethora of ATM threads, including personal attacks on Einstein, it’s getting harder to justify one‘s efforts to have normal discussions of disagreement, though your the exception to this, thankfully.
