The Borde-Vilenkin-Guth Theorem states that any universe, which has, on average, a rate of expansion greater 1 that system had to have a finite beginning. This would apply in any multiverse scenario as well. There are four exceptions to the theorem.*
For a greater context please see the first exception to the BVG theorem, which is Initial Contraction (Havg<0).
The third exception: Infinite Cyclicity (Havg=0)
Example: Baum-Frampton “phantom bounce”
These models suggest that the universe goes through a cycle in which it grows from zero (or non-zero) size to a maximum and then contracts back to its starting condition. The verage expansion rate would be a pure zero.
