Latest Gravity Probe B Stories
NASAâ€™s Gravity Probe B (GP-B) has produced astonishing new confirmation of two key predictions derived from Albert Einstein's general theory of relativity, which the spacecraft was designed to assess.
WASHINGTON, May 4, 2011 /PRNewswire-USNewswire/ -- NASA's Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein's general theory of relativity, which the spacecraft was designed to test.
NASA will hold a news conference at 1 pm EDT on Wednesday, May 4, to discuss the science results and legacy of the Gravity Probe B (GP-B) mission.
For the past three years a satellite has circled the Earth, collecting data to determine whether two predictions of Albert Einstein's general theory of relativity are correct.
Is Earth in a vortex of space-time? We'll soon know the answer: A NASA/Stanford physics experiment called Gravity Probe B (GP-B) recently finished a year of gathering science data in Earth orbit.
Almost 90 years after Albert Einstein first postulated his general theory of relativity, scientists have finished collecting data to put it to a new, different kind of experimental test.
This year marks the 100th anniversary of a revolution in our notions of space and time. By measuring the shape of space with exquisite precision, NASA's Gravity Probe B aims to confirm Einstein's theory of relativity ... or provide the first evidence against it.
A key prediction of Albert Einstein's general theory of relativity has been confirmed by an experiment showing that the Earth's rotation drags the surrounding fabric of space-time along with it. The phenomenon, known as frame-dragging, was one of the last untested predictions of general relativity.
