Query: Remarks on the "New Redshift Interpretation"   In a recent article in {\em Modern Physics Letters} {\bf A}, Gentry proposed
a new static cosmological model that seeks to explain the Hubble relation as a
combination of gravitational and Doppler red shifts. We show that Gentry's
model, although supposedly based on general relativity, is inconsistent with
the Einstein field equations; that it requires delicate fine tuning of initial
conditions; that it is highly unstable, both gravitationally and
thermodynamically; and that its predictions disagree clearly with observation.
