But we've recently discovered that the expansion of the universe has accelerated. I understand this to mean that the recession speed of receding galaxies has increase, and so the distance at which galaxies are receding faster than the speed of light is getting smaller. So the horizon surface is shrinking and with it the entropy proportional to that surface area must also be decreasing.

The question is how has matter inside the cosmological event horizon accommodated a shrinking horizon and the decrease of entropy of that horizon? Does gravity cause things to clump together to offset this reduction in entropy of a shrinking horizon due to acceleration in expansion? Does life form on a few planets inside the volume of this shrinking horizon? Or do galaxies recede behind the horizon whose entropy is equal to the amount of entropy decrease of the shrinking horizon? Or for that matter, does in fact the cosmological event horizon shrink with accelerated expansion rates.
