Sure, but this is not science. Science is about the observable. “Other universes” are not observable, so you can’t do science about them. It is science-fiction.

There is ONE universe. “UNI” is from Latin for ONE.

"There is ONE universe. “UNI” is from Latin for ONE."

It comes from the ancient Latin word Universum. Not exactly the latest science.
