All the matter in the Universe will eventually come back together, no matter what....(pun intended)

Matter distorts space-time. Imagine a universe where there exists only TWO hydrogen atoms, nothing else. Even if they are a billion light years apart, they will eventually collide.................

I agree with you. My gut feeling is that you’re take is right and the Dark Energy theory is flawed.

Well if *Dark Energy* follows with everything else in the universe, it will eventually wind down and the *Big Crunch* will begin.
Unless gravity/Higgs field winds down also, than who knows?

Just a shot in the dark :)
