I've looked quite a bit on this forum and also elsewhere online and I cannot really find any information on my inquiry. If this is a double post please delete and send me in the right direction. Now I may be totally off on my thought process, but as I understand it the CMB first started off as gamma ray radiation and has since redshifted to the radio. At some point in this redshift journey it must have passed through the visible spectrum. Which leads me to my question: If we were alive during that time when it was shifting through the visible (assuming there was a time), would the "night's" sky have been bright? Since the CMB is literally everywhere, would we not even be able to see due to overexposure? Or would the CMB have not been intense enough to even visibly see during this time? Once again thanks for any insight!
