I should make it clear that gravitons, neutrinos, etc are very small "measuring" effects normally as compared with photons, air molecules, etc. The usual physicist's patter about how those latter things cause decoherence is fine, except that they sort of inherently depend on the "environment" (air, material near slit, etc) being aleady non-wierd, well localized, un-entangled with the state of whatever they "measure." Without that assumption those explanations get hard to be sure of. With my graviton based explanation, this regime also is taken care of. Point is, you need some "ground truth" at the bottom of the cascade of bull. If you provide it, ok. If you do not, things get dubious.
