Most discussions about the big bang suppose, implicitely or not that the redshifts are purely Doppler (or expansion) or gravitational. The CREIL is an elementary effect which explains all extra redshift very simply: they happens if there is some excited atomic hydrogen on the path of the light !
It is difficult to discuss using the observation of far objects (although finding the spectrum of hydrogen from the observed redshift seems remarkable !).
Therefore, I studied the anomalous frequency shifts in the solar system. There are, in my knowledge three anomalous frequency shifts:
-UV émissions lines in the chromosphère, badly explained by spicules or magnetic syphons; (

; published in AJ).
- too high frequency of the radio received from probes distant of more than 5 UA (arxiv:gr-qc/0104064; pub. Phys. Rev. ;too: gr-qc/0208046)
- anisotropy of the CMB bound to the écliptic (arxiv:astro-ph/0403353; Phys. Rev. Lett.).
It is remarkable that all these anomalies happen in conditions where the electromagnetic waves cross excited atomic hydrogen; see arxiv: physics/0507141.
