This site is dedicated to a theory of gravity based on space providing the energy for all physical existence. The general concept is easily stated, the base model construction is not so easy. In a nutshell, the theory states space provides power (energy over a period of time). When there is no physical existence in space (i.e. matter), space's power is at a maximum. When matter appears, it forms a "drain" on the power at that point in space. All surrounding space's power "drains" into the deficit in power caused by the matter.

The concept, a deeper look.
