Excuse me men, Just to ask, does the fact that we can not perceive or say "see" beyond the universe mean that there's nothing beyond it. Ok may be mathematically it does. But I am asking from such point of view that: if we can not feel the effect of something and we can not see it does it put it FINAL that there is "nothing"?. But again I think we perceive an effect, everyone of us (before we learn astonomy or even after we do) is aware of the concept "beyond" or "besides" and we certainly have doubt that "something" is beyond the universe. "something we can not perceive" but it is still something because we can still think of it. May be our perception is incomplete. We just cant see in the dark without a torch, but nocturnals can. We might need to develop an additional sense in order to interact meaningfully with what we brush off as "infinity". Thanks.
