I checked few links about it as follows:
I see mentioned CBM discovered at different wavelength at different time moment as for example 3.2cm or 1.9mm or other values.
Why these differences? Which one is accurate or more important?
I cannot find anywhere, calculated or estimated the wavelength of the CBM radiation at the Big-Bang moment or at least at the age of 1s when the temperature is estimated 10 billion Kelvin.
Any help with CBM wavelength at that early stage of 1s?
