Suppose there isn't anything at all beyond our Universe.It is a well
known fact that light has Mass/Light is a Physical thingy/Light does
exert Pressure.If there isn't anything at all beyond our Universe,does
Light escape from our Universe (actually,God's Universe) and into and
beyond our Universe? If so,I think that means beyond our Universe,there
is Matter/Atoms/Light beyond our Universe.A perfect Vacuum (in my
opinion) does not have so much as one tiny Atom,or part of an Atom
inside of a perfect Vacuum.
I think only only The MAN upstairs knows for sure.
