Cosmic Microwave Background radiation is coming to us from about 13.7 billion light years away... is that correct?
The reason its coming from 13.7 billion ly away is because the universe is 13.7 billion years old... is that correct?
so when the universe was only 12 billion years old the CMB coming to us was slightly hotter and coming to us from 12 billion ly away?
And using the same logic when the universe is 15 billion years old CMB will come to us from 15 billion ly.. is that correct?
