sorry about the fantasy factor here guys, but having a kind of barrier that can repel mass and be "mass less" without having any visible infrastructure would be quite valuable. so the question is: What are force fields? (like the ones in star trek) what would they compose of? and what keeps us from that technology? i'm not talking about the effect that magnetic or electric fields have upon charged particles. simply the science of a fantasy (or is it?) The effect of of repelling both protons, neutrons, and electrons. *note does any "theory of everything" in quantum physics (etc..) Predict such a phenomenon in the universe?
