How can multiple infinities coexist in a multiverse?

[dpa]

any one universe is infinite.

So as there are multiple (parallel right?) universes, how do multiple infinities co exist?

Lets say, even conceptually or mathematically?

If not parallel, then again, what happens after completion of 10^500 universes?

 

[mathman]

any one universe is infinite.

Current description of our universe is that it is finite.
