One of my friends majoring in physics with me was telling me that the CMB radiation was not "predicted," by the big bang cosmology, but was in fact a "post-diction," and that the range of values for temp. obtained by Penzias were in fact way off, 5K to 50K and that other "cosmologies," can more accurately assess the temp. 2.7 K. He couldn't tell me where he remembered reading about this but the claim seems to be coming from the following, Mentor note: The "following" is a reference to an article in an unacceptable journal. AdkinsJr you want to learn physics, the journal Apeiron is one of the very last places one should go. I have deleted the reference and the summary thereof. I can't find much discussion on this topic so I thought it'd be interesting to post since I don't know much about cosmology. I knew that the CMB radiation is considered a turning point in the history of the model, but I am not familiar with the details, is this information correct?
