I write as an intersted ignoramus.
I have often read that studies of background radiation can take us back to, or give us information of, the earliest stages of the universe, when, as I understand everything was pretty close together. How is it that radiation from 14 billion years ago is reaching us now, when that radiation should have left Earth far behind?
