An Explanation for Gravity

This paper is a sequel to CERN-OPEN-96-008 in which a classical model for reality was presented. Seen from outside, this model world consists entirely of classical mechanical waves in a granular medium possessing a large spherical boundary. Surprisingly, this seemingly barren configuration can be shown to contain quantitative explanations for special relativity, the essence of classical quantum mechanics, the existence of hadrons and leptons and classical electricity including charge and the Coulomb force. An analytic result, not depending on any numerical input, is a spectrum of hadron mass ratios agreeing with experiment within 1% r.m.s. up to about 1.3 GeV. Here it is shown that classical gravity is contained in the same model without requiring any additions, be it in concept or in numerical input. The essence of general relativity is recovered in the form of strain in a medium. But beyond this, the strain’s generation by a source mass’ is explained and related to the fine structure constant and the classical electron radius. Newton’s gravitational constant is found within 0.42% of reality.
