But this is what concerns me as well. Yes, the effect is significantly - several orders of magnitude - greater than what the theory predicted, however there's no reassurance that it's outside local noise in the lab. "Gravity probe B" was extraordinarily sensitive and safely outside local noise. I suppose the next step in testing this effect would really be to try it in space.
