Maybe Norman is confusing the rather more legit idea that the "fluctuations" 
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.' "
