In a recent article,(1) Gentry proposed a new static cosmological model tha
t seeks to explain the Hubble relation as a combination of gravitational an
d Doppler redshifts. We show that Gentry's model, although supposedly based
on general relativity, is inconsistent with the Einstein field equations:
(a) it requires delicate fine tuning of initial conditions; (b) it is highl
y unstable, both gravitationally and thermodynamically; and (c) its predict
ions disagree clearly with observation.
