- On a philosophical level, what is the meaning of a Universe with a finite
- size? What is happening at the boundary between that which is the Universe and
- that which is not? And, what would happen if I stepped into that region which
- was defined as the "Non-Universe?"
-
- On this very non-rigourous (even symplistic) level, there can be no boundary to
- the Universe. Any "region" found outside the Universe would automatically
- become part of our Universe (which would have just expanded to include the
- "region" you were interested in). I belive this provides a qualitative descript
- ion of the "Infinite Universe."
