Instead of calling this event, the separation of radiation from matter, separation of light from dark, or the "big bang," I'm now going to call it "The Big Slap and Tickle."Wow. The Big Gong.
I wish I was educated sufficiently in maths and physics to have a sensible comment.
If I get the basics, the video is suggesting that there is an overtone series in the frequencies of background radiation. This implies that something ( dark matter ? ) constrains the expansion of the universe, and further that this force of constraint is analagous to a string (as in guitar) being 'tied down'.
That is psychedelic :rainbow1:
We wouldn't be able to make music if we weren't a little tense. LOL.
