The Penrose cyclic Multiverse is always expanding even decelerating is wrong, by the String Black Hole implosion or the Big Crunch String Black Hole.
Why do we measure the accelerating expansion? because the oscillating virtual vacuum fluxtubes are elongating around massive objects and decreasing the local lightspeed around galaxies. So the universe only looks accelerated.
