Why does the universe exist? 7.2

“There is nothing in that region of space”


“there is nothing outside the universe”

have different meanings.


there is nothing except quantum fluctuations in that region of space

= the best detector detects nothing but quantum fluctuations


there is nothing outside the universe

= whatever detected, label the whole collection as “the universe”


“There is nothing outside the universe” does not (!!!) mean that “we go outside the universe to keep searching, but find nothing”.
