Does anybody know why QFT predicts a vacuum energy density that is
wrong by
1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000?
Give or take a few zeros.
Here's why, and, better yet, here's a way to resolve this horrendous
howler.

You may be right, there may be some circularity involved in my
invocation of Avogadro's number -- but you seem to agree that the
countability of atoms is not in doubt, anyway.
