the space around earth space-time existing measuring distortion effect

Phoenix nets technology - May 6, news, according to foreign media reports, recently the U.S. space agency, NASA gravity satellite B (GP - B) plan confirmed Einstein relativity, two key predicted the spacetime surrounding earth because gravity and distortions.

The trial begins in 2004, using four MEDALS high precision gyroscope to measure the spacetime surrounding earth distortions and other parameters.

GP - B, pointing to a single star, IM Pegasi, and in the polar orbit circling the earth with unprecedented precision measurement, the spacetime surrounding earth torsion. If gravity of spacetime without causing reverse, then in orbit, GP - B the gyroscope will always pointing in the same direction. But according to Einstein's theory, the earth gravity will make the spacetime surrounding earth happened, so in fact, twist to a gyroscope detect in its rotation direction very small change, and this is the result of earth's gravitational influence.

This experiment in Physical Review details will also posted on the website of the Letters journals.

"Imagine the earth immersed honey, local ball rotates, the honey will also with around, and produce vortex, too." spacetime Francis. Rick Francis Everitt Everest "), GP (chief scientist - B project, Stanford university professor, "explains that the GP - B confirmed Einstein theory of relativity of the universe of two important prophecy, the astrophysical research has far-reaching influence. Similarly, the project of technology innovation is also behind the earth and space research and precious treasure."

GB - P project is NASA history one of the oldest project operation, since MBT Kipimo clog 1963, this project since autumn early preparation began. Subsequent decades technology breakthrough development, make people can control the environment of the influence of disturbance spacecraft, such as air resistance, magnetic field and thermal changes, etc. The gyroscope and celestial trackers adopted the greatest precise design and production process.

The test of GB - P use can make the GPS technology independent landing aircraft, other related technology has been applied in other studies for NASA, such as the cosmic background detection task, this measure can confirm thatmbt sandals clearance the big bang theory foundation, and make NASA physicist John djoser (John Mather. Horse) won the Nobel Prize.

GP - B in December 2010 completed data acquisition and operation of the job and retirement. NASA astrophysicist and senior scientist bill. DanJi said program, "the future of Einstein's general theory of relativity further confirmation of than the GP, needs to adopt a more precise - B measuring equipment." (compilation / 77
