We know absolutely nothing beyond this universe. We barely even know much about this universe. You can't meaningfully speculate about the nature of what (if anything) is dimensionally/physically/extra-universally "outside" of our universe. We don't even know what that means, much less if it exists or what the number/nature of it would be. Our universe may be a piece of candy floating on a chocolate river in another universe that flows eternally. It's all just make believe. Make believe can be fun, but let's not pretend that we're doing anything more substantial than what three year olds do when talking about space robots.
