  As shown previously, quantum mechanics directly violates the weak equivalence
principle in general and in all dimensions, and thus indirectly violates the
strong equivalence principle in all dimensions. The present paper shows that
quantum mechanics also directly violates the strong equivalence principle
unless it is arbitrarily abetted in hindsight. Vital domains are shown to exist
in which quantum gravity would be nonapplicable. There are classical subtleties
in which the strong equivalence principle appears to be violated, but is not.
Neutron free fall interference experiments in a gravitational field reveal some
evidence for a violation of the equivalence principle. Galileo's falling body
assertion and the misconception it leads to, are examined,
