How important is the Gravity Probe B confirmation of the geodetic effect? My amateur opinion is it's very important for geometric theory. Any theory which describes spacetime using dimensions of space and time. No mater how many dimensions. I think it might 'round file' theory based on other stuff, like aether theories which allow for the detection of the aether or aether theories where the aether isn't detectable like Lorentz ether theory. I could be missing something in my amateur analysis?
