Towards a Unified Theory of Forces

A theoretical model is proposed that unifies the forces of gravitation, electromagnetism and the nuclear (strong) force. The classical electron radius, Dirac's Large Numbers and an explanation for electron spin follow from the model. The Mach relation of cosmology is derived and applications to modern astrophysics are indicated. These include an explanation for the accelerating expansion of the universe and a force equation for the higher order gravitational properties of binary pulsars.
