### G FLUCTUATIONS AND PLANETARY ORBITS

**Commentary**: This was a response to comment by E. W. Crew on the
author's earlier paper [1977c]. That earlier paper had discussed the author's
space domain theory and the consequences of boundary crossings upsetting
gravitation at intervals between periods of geological time, the latter having
been first introduced in the author's 1972 book *'Modern Aether Science'.*
Crew stated that the author had not considered the effects on planetary
orbits.

By this response the author calculated the effect on the eccentricity of a
planetary orbit that could be expected from a single domain crossing. It was
shown that the author's prediction of catastrophic effects owing to G
fluctuations at times of a space domain crossing was in no way disproved by the
existing data for the elliptical orbits of the planets.
