To anyone with more than a passing interest, something no-one seems to address is the fluid-flow nature of everything - you know, non-linear stuff, aka what is described by Chaos Theory.
You can bet your bottom dollar that the expansion of the universe isn't uniform, it'll follow non-linear fluid dynamics.
To help, picture the billowing smoke clouds above a just-erupting volcano - as the cloud expands some race out into half-spheres and then are overtaken or swallowed up by others billowing faster.
That same sort of thing has to, just has to be happening to the expansion of the universe!
Of course, in the surface-of-a-balloon picture that's often used to help us picture how everything's moving away from everything else, it's not see easy to visualise some parts of the surface expanding more rapidly than others while overall still remaining a sphere.
Even so, it must be happening.
So where does that leave our observations that there must be dark energy causing the accelerated expansion of the universe?
Well, in that billowing cloud image in your mind, even after the eruption has stopped and the overall cloud expansion is slowing, there will still be, through momentum, some areas still doing the billowing thing.
With my own limited understanding of these things, I'm quite happy that what I hear about dark energy somehow equates to momentum in my analogy, and it could be that we're in one of the billowing bits, while overall the universe expansion is slowing.
I'd be interested to hear what those in the know think :)
I'll just finish by stressing, everything is fluid flow - nowhere is it absent, it's always there hiding in some form or other. Even in the digits of Pi and e.
