Query: The zero-point energy of elementary quantum fields   Since 1925, exactly four arguments have been forwarded for the assumption of
a diverging (respectively --- after regularization --- very huge) zero-point
energy of elementary quantum fields. And exactly three arguments have been
forwarded against this assumption. In this article, all seven arguments are
reviewed and assessed. It turns out that the three CONTRA arguments against the
assumption of that zero-point energy are overwhelmingly stronger than the four
PRO arguments.
