Re: What is "uncertain" in quantum physics?

 Is there some experiment that settles "uncertainty" as something "really
there"?  In particular, I am not sure if the expansion of the Universe
is such evidence, or rather a consequence of the theory.
 Thanks for any insight.

Interesting.  A statement or question actually
about physics.
If something is 'quantized' in quantum mechanics
it is actually there are not there.
Take an electron.  It actually has a specific
rest mass or charge.  It does not have an infinite
number of fine degrees of mass or charge.
If one were to form from say high energy electromagnetic
radiation and an anti-electron, it would not just partially
form a partial quazi-electron.  This uncertainty about forming
or not forming is called an 'Uncertainty Principle'.
Then there is all of this degenerate philosophy about how
nothing can every be truly certain or known.  This is
flatulence and defecation produced by physicists in
the early 20th century.  I would suggest that you do
not worship this flatulence and defecation.  Just notice
that in the world of the very small, some things are
'quantized' (in other words, there are not an infinite
number of fine degrees of rest mass or charge than an
electron can have).
