However, logical analysis suggests that the distance between any two universes in
the infinite vacuum would also be infinite. Read and understand the following:
a) The odds of a universe beginning are infinitessimally small, a finite
probability.
b) The lifespan of of the average universe is also finite.
therefore, c) follows:
c) There are a finite number of universes in existence in the true vacuum at any
given time.
If this is true, then a finite number of universes spread through infinite amount
of true vacuum makes the average distance between two universes infinite.
Because of this, no two unverses can collide. Prof. John Cramer has suggested
that it may be easier to build a wormhole between two different universes than
between two points in the same universe. Why? Because if you have two ends of a
wormhole within finite distance of each other you will generate a causal loop,
which is amplified in proportion to the amount of relativistically caused
temporal shift between the time frames of the two ends. When you have such a
shift, as has been posited for a wormhole used for time travel, you will get some
matter which goes back in time through the wormhole, then travels back to the
original mouth, and goes back in time again, etc, eventually causing so much
matter to travel in this loop that you cause the universe to implode.

Universes as we know them are merely aberrations in the stability of the true
vacuum. It cannot be a perfect vacuum, because perfection is unstable.

Its called the Multiverse.
