Do you propose a form of cyclic universe? why don't we have enough matter for this, even with the dark matter and dark energy tapes.
Yep! You are new! Welcome aboard. My position has been throughout my time here that the universe, and all of the infinities of universes, are always rolling over . . . always in turnover . . . always diverging, always converging, always in movement, always in change, always in (always repeating) beginning, middle, and end, in the same eternity in an instant, a moment, of time ([past (into the future) | future (into the past) . . . totaling up to T=0(1), t=0(1). In other words, "steady state."
"Universe" means "a turning unity" (a constantly, forever, turning unity).
I've just spent a lot of time and space tweaking my picture, my model 'Atlanoverse'. All the way to recently changing some century and longer held premises that just weren't firmly holding up at all (vis-a-vis everything above in my first post and more) for me. The more modern findings, works, books and articles I read today, premises that are no longer firmly holding up for many pros in physics and cosmology either. Pros who apparently in larger numbers are increasingly speaking out.
Even quotes from ones long gone are coming back to the fore:
"Please don't hold me to anything I said before I knew better." -- Albert Einstein. The puzzle he spent so long helping to work up would never unify, never piece together, for him either. Parts seemed to work, but overall, it just kept falling apart for him, too. Me, I work from what I know best in my own nature, my own capabilities, abilities, fields and experiences, the more unifiable apexes of the pyramidical set, top-down, bottom-up, farthest outside-in, deepest inside-out (again, farthest outside-in), and leave the alligator filled swamps between to the pros always up to their necks, if not over their heads, in its complexity and chaos.
