Maybe Norman is confusing the rather more legit idea that the
in the Big Bang, that explain why the universe is not completely uniform,
come from quantum fluctuations amplified by inflation. This is currently
the leading theory for the origin of structure, in that it has quite a lot
of successful predictions to its credit.

Perhaps I didn't express myself well. What I was referring to is at
http://www.astronomycafe.net/cosm/planck.html, where Sten Odenwald
hypothesizes that random fluctuations in "nothing at all" led to the Big
Bang. "This process has been described by the physicist Frank Wilczyk at
the University of California, Santa Barbara by saying, 'The reason that
there is something instead of nothing is that nothing is unstable.' ". . .
"Physicist Edward Tryon expresses this best by saying that 'Our universe is
simply one of those things that happens from time to time.' "
But as I said, this idea is pure speculation, there isn't any evidence for
it and we'd probably need a fully worked-out theory of quantum gravity to
see if the idea even makes sense.
