Something's not right here.

How can it be accelerating? That implies a force pushing on it. If it were this mythical dark matter, then that would need to

a) be constantly created behind the expanding edge (because we know there's nothing beyond the edge)

b) employ anti-gravity to 'push' the stars out from behind.

So, go on - explain it in simple terms.
