OK, here's a naive but hopefully reasonable question.  Why can't
inhomogeneities arise in a homogenous medium due to the Uncertainty
Principle?  I picture the Universe soon after the big bang as being a
very dense soup of energy and particles (i.e. various kinds of waves).
It's close and dense enough that quantum effects could make changes
that would show up as huge inhomogeneities in a later expanded version.

What's wrong with this innocent picture?
