A Simple, Heuristic Derivation of our "No Backreaction" Results
  We provide a simple discussion of our results on the backreaction effects of
density inhomogeneities in cosmology, without mentioning one-parameter families
or weak limits. Emphasis is placed on the manner in which "averaging" is done
and the fact that one is solving Einstein's equation. The key assumptions and
results that we rigorously derived within our original mathematical framework
are thereby explained in a heuristic way.
