I think the difference between your theory and the general idea in physics is that you give it a different philosophical view point, not that it is a different physical theory. Light is what objects repel and absorb, and eject on each other (they actually also eject other kinds of energies between them: they move each other, they heat each other, they give sound to each other...). So in that sense it is (said in a different way) the glue between matterial bodies.
