Do you ever think about the shape of the universe?
How would you describe the shape of the whole thing?
We can talk about the center of the universe as well if you like.
Under the Einsteinian view, the big question was whether the universe was open, meaning it would keep expanding forever,
or closed, meaning its expansion would eventually slow down and stop, at which point a giant contraction would begin.
Which scenario would occur depended only upon the average density of matter over the entire universe. If the density was high enough, then the universe was closed. Otherwise it was open.
The discovery in the 1990's that the expansion of the universe was actually accelerating threw a wrench into this view. The current hypothesis is that this is some unknown form of energy, named dark energy, although really we have no clue what it is. "Dark energy" is just a placeholder for "that which causes space to expand" .
With dark energy and an accelerating expansion, it now seems clear that the expansion of the universe will go on forever.
And because the expansion is accelerating, there are places in the universe that will never be .observable from other places.
They are beyond each other's event horizons. It's fascinating to think that there may already be more beyond our own even horizon than within it--perhaps much, much more.

I vaguely remember a long time ago watching a show on the science channel that said the universe was some funky twisted torus-like shape.Do not quote me on this. Because it was so long ago there is a high probability that I am remembering incorrectly or that this information was valid then but has since become outdated.

When a woman pushes-Out the baby/fetus it is resultant of pulling-In contractions of the muscles. Dark Energy and all other pushing-Out phenomena is a resultant of pulling-In phenomena. This is the path of least resistance.Dark Energy )( expanding Space is Universe relaxing just as a muscle expands when is relaxed. At least that is one option.
You're talking out of your ass.
Modern science has no idea how or why dark energy works or what it is.
Your idea that dark energy will eventually 'tire out' or be 'overpowered' by gravity in the long term is completely unfounded.
So does it take an a__hole to know when an A__hole is speaking?

Naw, you know an a_hole is talking when it's lips are moving. Visualize that.
