The Machinery of Gravity oleh David Franklin

Describes the machinery of gravity based on the idea that all matter is expanding forever. Derives equations showing that the intuitive notion that this idea can not be correct because objects of different densities would change sizes is wrong. Instead because nothing can go faster than light speed, objects regardless of densities or geometry converge in sizes such that the ratio of all sizes remain almost time invariant. However, there remains a very small difference in the ratios that can be measured under some conditions and shows up in certain long distance measurements. One example being the three Pioneer 10/11 anomalous accelerations and the apparent (but unexplained) expansion of the earth. The idea is developed and then applied to six problems in physics (bending of starlight, advance of the perihelion of Mercury, behavior of spiral galaxies, expansion of the earth, anomalous acceleration terms for Pioneer 10/11, and acceleration of universe expansion) showing very nice explanations and solutions matching measurement results with (in some cases) simpler solutions than in the literature.
