NASA’s gravity probe b satellite confirmed Einstein’s general theory of relativity

According to foreign media reports, the United States confirm NASA’s gravity probe b satellite project team, has been successful for Einstein’s general theory of relativity of two crucial corollary: reference frame dragging and Geodetic effect, with accurate validation and measurement, the conclusions have been published in the international on the important academic Physics journal physical review letters.

Gravity probe b (GP-B) is a United States Space Agency’s 2004 launch of scientific satellite for measuring space-time curvature of the Earth, seeks to fully verify the correctness and accuracy of Einstein’s general theory of relativity. Main using four a super high precision gyroscope to measurement predicted in the of super large quality object makes the object around spatio-temporal produced of curvature, this time and space Shang of distorted also will was the object rotation by effect, popular to said: Earth of super large quality makes around spatio-temporal produced distorted, and Earth of rotation also will led around spatio-temporal with of rotating, this is reference Department drag pulled, or gravity magnetic, is Reims-Teeling effect.

To guarantee measurement of accuracy, GP-B satellite work environment must away from all may exists of interference, for this is, satellite was placed in 642 km around of very track Shang, to provides a perfect of spatio-temporal reference Department, and contains has a links to fly horse seat HR8703 (is IM Pegasi) of reference telescope, this HR8703 is a quasar, because its has relative strong of radio signal and location ideal, was will its as navigation stars. And the rotation of the gyroscope’s axis is pointing to HR8703, if Relativistic effects are correct, that space-time is curved, gyro can reference frame dragging and Geodetic effect caused by the change from the perspective of detection, on the contrary, the four gyroscopes point will always be parallel to the angular momentum.

Given the current experimental progress and achievements made, Washington senior astrophysicist at NASA and the team member and Chief researcher of the GP-B agree that this will have a more profound impact on astrophysics research. However, the GP-B project results has been updated for global positioning system technology, and some conclusions will also be applied to the detection of the cosmic microwave background radiation task aimed at accurate measurements of the microwave background radiation parameters, and as support for the big bang theory, this derivative theories makes NASA physicists John Mather won the Nobel Prize.

In addition, the GP-B task also led to a certain extent the enthusiasm of the students, including 100 PhD students and 15 graduate students throughout the United States, more than 350 students and high school students and Aerospace engineers and scientists involved in the project, was also born during a female astronaut and a Nobel Prize winner (mentioned above).

Overall Gravity of Probe-B project management, operations and research by the NASA Marshall Space Flight Center and completed at Stanford University, Lockheed Martin company responsible for the design, system integration, and loads of space section. The tasks on the results of theoretical physicists will have a long-term impact, and future will continue to use more sophisticated instruments for verification of general relativity.
