Observation is a cornerstone of science and theorizing about something you cannot observe is interesting but not science. This is speculation about what might be outside the observable universe and that could lead to science disproving those particular speculations, but speculation is not science, it is philosophy.

In fact, this is even more important to science than direct observation, which is extremely limited. By direct observation, I can't even tell if the earth was here yesterday, or at least a thousand years ago, even less so if it will still be here tomorrow. By the same token, when you look at certain characteristics of what you can observe of the universe, and you take the known laws of physics, you can find out a lot about the unobserved, and the un observable, universe.
