A Shifting Theory Of Gravity
   This theory proposes a physical mechanism for gravity - free gravitons randomly strike and are absorbed into a particle, which then expels other gravitons. Includes a paper describing the theory and a simulation program for download.

An alternative theory of gravity
   There is no 'gravitational force'. The universe is expanding, and 'gravity' is one of the results.

Gravity and Space
   A continuous, magnetic field fills universal space; and also permeates all matter. Hence, a virtual continuum of a single, real field describes gravity.

Lorentz-Poincare relativity and a scalar theory of gravitation
   Special relativity may be derived from Lorentz contraction. It follows that the relativity principle could be broken in the presence of gravitation. This seems to work.

Spin-Orbit Duality, Astrodynamics and Anti-Gravity
   Seen from orbit, the earth rotates. Spin-orbit duality therefore allows antigravity to be mathematically specified. Equations and theories can be seen to emerge from the known.

The Gravnetic Field
   The existence of a vector field is shown, originated by all moving masses which exerts a force on all other nearby moving masses.
