> graviton particle and the Higgs tells space which way to curve

The Higgs does not play that kind of role. It is a common misconception, since Higgs it often referred to as "giving mass to the other particles", which is true, and called the Higgs-mechanism, it does not influence the curvature of space-time that way. That is all due to the graviton (assuming, which it is also commonly believed, that gravity is quantised).

Mass is one thing, interactions between masses another.
