another dumb question here...

Has anyone ever tried to come up with a theory that gravity is the net strong force minus the net weak force (between 2 objects)?

Has anyone ever tried to come up with a theory that gravity is the net strong force minus the net weak force (between 2 objects)?I think you better first come up with a better description of "theory". A theory is neither a guess nor some hypothesis that needs to be proven. A theory is a set of basic rules supported by a great many observations by many scientists, that explains and makes sensible a large number of facts, that without the theory, would seem unconnected. Is is an though the facts and observations are a number of dots and lines, representing cities and country and state boundaries respectively, making no sense. A theory is a map that puts each dot and line into the right place and makes a connected and sensible picture out of it all.

Secondly, gravitation is far weaker than the weak force at the subatomic level. Subtracting that from the color force will not result in a force that is 10^37 times weaker than the electrical force

So photons don't feel gravity or contribute to it? Neutrinos, electrons and so on feel the opposite sign of gravity to hadronic matter as they don't feel the strong force? I think we would notice.

The strong and weak force have utterly different symmetries, operate on totally different charges and act on massive and massless particles. The weak force has massive bosons associated with it which would provide another complication. Anyone coming up with such a theory would find it dead in the water before it started.
