The Gravity Prob Experiment and the Geodetic Effect

We're trying to see if somehow the dragging of space by spinning earth will somehow make these balls wubble exactly so that as two effects we're looking for here. One is the geodetic effect, which measures the curvature of space itself. And the other one ortognal to it tells us about frame dragging. Or we're talking about frame dragging and the gravity pro b experiment, and how it's trying to prove einstein wrong. A said.
