"what is outside the universe
?" is not an answerable question. The question itself is absurd
, since the universe is space
, is part of the universe. There is no outside the universe
for anything to exist in.
This is similar to the question "what was there before the universe existed?". This question is equally absurd, since the universe is the combination of space/time
, therefore 'before the universe' there was no time
for anything to exist
