This sounds terribly oversimplified to me.  Isn't it true that
mainstream cosmological investigation is considering several
possibilities beyond the simple nothing-everything model?  I thought it
was considered likely that the universe is expanding into one or more
dimensions which are physically real but undetectable by our
3-dimensional perceptions.  I thought there are plausible models which
allow for a pair of universes, or even many similar universes.  Am I
getting my science and my science fiction mixed up here?

Since The Creator seems to be so fond of creating things in opposing
pairs (quark-antiquark, electron-positron, beta-antineutrino,
positron-neutrino, etc.), I'm intrigued by the possibility of a
universe-antiuniverse Creation many billions of years ago.

Best wishes,

Larry
