If what used to be visible light when the universe was smaller and younger has been stretched due to the Doppler effect so that it is now microwaves and detectable as the Cosmic Microwave Background Radiation that can be found everywhere, why hasn't the gamma or x-rays of the same period not been stretched into the visible light range and also found everywhere?
This occurred to me watching about Olbers' paradox and I couldn't find any information on it.
Thanks for any help.
