If I claim the universe is the size of a fish bowl.

I mean that in perspective to something much greater in size then our universe.  That something could be a mystery force on our universe as ours being within the much larger place and very connected with it.  Signals from something coming into our universe which might have slightly different laws of physics.  If so much science would be slightly imperfect, which may be an okay idea.  It opens the idea of the unexplainable phenomena.
