Question: How likely do you think there is a parrell universe??

Hi, Well it’s been a while since I have done any physics to do with parallel universes but I would like to think that there are parallel universes. If we think about the fact that our universe is expanding like a giant balloon with everything existing on its surface then I think its possible that there are other balloon universes also existing that we know nothing about. It does make you think though as to how many there would be?
