You are dodging the questions, dummy, because you don't know why the CMB exists. If you knew why the CMB exists, then you would understand why the universe began.
But you don't, so you post anything from a google search that looks like the universe may not have begun. Unfortunately for you, the CMB is the fingerprint of a universe that was created from nothing. It's the smoking gun. It's the evidence that the universe began.
I do. If you recall, i had to correct several of your errors on it in the past. I dont think they are proposing any difference in how the CMB originated. They are proposing that black holes colloded in a prior eon, and the resulting gravoty waves left a signature in our CMB radiation.
And settle down, you're getting emotional.
