What's Mathematics of Frame Dragging ??? Since 1960, scientists have suggested that general relativity's prediction of frame dragging can be tested. The recent launch of Gravity Probe B satellite was to do this test. Can someone help me find the math behind this test? Edits: Found some information in the book by Ignazio Ciufolini and John Archibald Wheeler called "Gravitation and Inertia." The brief account of GP-B starts from page 332 to page 333. I am hoping to find more detailed math than this.
