Ah, that sounds like Le Sage's theory of gravity (http://en.wikipedia.org/wiki/Le_Sage%27s_theory_of_gravitation) in which objects are hit by some field of particles throughout the universe and the shading (from these particles) of one object by another causes them to move towards each other.This is interesting and causes me to ask the following question. If fields don't act like matter, and the Higgs field exists, what would preclude it from acting similar to the debunked Le Sage's theory? If of course, these fields could also produce this pressure. Just to be clear, I'm not proposing a new theory here, I'm just asking a question.
What's interesting is that most of these theories were replaced by classical field theories in which fields do not act like matter.
