Does anyone have any preliminary, or otherwise, information as to the results of Gravity Probe B?
Chronos said:Results of the frame dragging experiment have already been published [GR is right again!] The second half of GPB results [precession] should be out around the end of this year. I've not heard of any expected delays in releasing those results.
The purpose of the Gravity Probe B mission was to test two predictions of Einstein's theory of general relativity: the geodetic effect and frame-dragging. These effects refer to the way that massive objects, like the Earth, can warp the fabric of space and time.
The Gravity Probe B mission was launched on April 20, 2004 from Vandenberg Air Force Base in California.
The Gravity Probe B mission lasted for 16 years, from its launch in 2004 until its conclusion in 2020.
The key findings of the Gravity Probe B mission include confirmation of the geodetic effect, which was accurate within 0.28%, and the first direct measurement of frame-dragging, which was accurate within 19%.
The results of the Gravity Probe B mission provide strong evidence for the validity of Einstein's theory of general relativity and further our understanding of how gravity works on a cosmic scale. This information can also be used to refine and improve other scientific theories, such as quantum gravity.
