Universes Like Onions

Onion rings grow from the center out and their rings grow in spheres
with a liquid between and never touch. Universes grow from the big bang
out and their spacetimes never touch, Universes have a membrane that
separates them. Here is the way I see the onion rings of our universe.
First BB Next ring gamma photons Next ring Matter in the form of
gases. Next ring Proto galaxies Next ring Milky Way created. Next ring
Our solar system Next ring Birth of humankind. I will post all the
future rings but not right now TreBert
