A vent universe or a parallel universe

The question for a scientist (or someone in the sciences) is from Abraham.
Not to Rabbi Michai Avraham.

Are there parallel universes to ours?
Doubt?
Surely there is?
Surely not?

And now a question for Rabbi Michai Avraham.
Does Judaism have any say on the matter?

(I have a NFPK because I'm not doing well here, maybe someday there if there is a place I will succeed? Exams change place changes luck)
