Dark Energy as Black Holes
I have no formal education in astronomy or physics, just read books and watch science videos for fun, and I'm curious about the technicalities of this theory, if it's a theory actual scientists entertain at all.
My thinking is that our observable universe is not the entire universe, that our big bang is not a singular event divided from other physical events (and big bangs could be part of a black holes' life cycle), and that contraction and expansion are relative terms and can seem different whilst still being the same thing(?)(ie, if the Earth was "falling" into a sun or a black hole or whatever, but if that sun or black hole was falling into something even bigger, wouldn't it seem like the sun or black is expanding from the earth's POV, even though it's being subjected to the same process?).
If our universe, or rather, all "observable universes," are eventual/former black holes, wouldn't that mean that we are subjected to the gravity of other unseen masses/energies that exist but are too many light years away from what's observable through any form of light? If Dark Energy is not constant, if it shows signs of acceleration and/or slowing down, wouldn't it make sense if it were because other processes not different from what we see in our "universe" - stars, black holes, planets, novas, dust, etc, everything that naturally forms in our universe - are going on and changing "outside" our universe?
