The experiment, launched in 2004, used four ultra-precise gyroscopes to measure the hypothesized geodetic effect, the warping of space and time around a gravitational body, and frame-dragging, the amount a spinning object pulls space and time with it as it rotates. GP-B determined both effects with unprecedented precision by pointing at a single star, IM Pegasi, while in a polar orbit around Earth. If gravity did not affect space and time, GP-B's gyroscopes would point in the same direction forever while in orbit. But in confirmation of Einstein's theories, the gyroscopes experienced measurable, minute changes in the direction of their spin, while Earth's gravity pulled at them. The findings are online in the journal Physical Review Letters. > Link to comment Share on other sites More sharing options...
Bryan R. Posted May 4, 2011 Share Posted May 4, 2011 Truly amazing that he was able to contemplate such concepts of space and time without any precedent. What a great man. Link to comment Share on other sites More sharing options...
Farstrider Posted May 4, 2011 Share Posted May 4, 2011 Truly amazing that he was able to contemplate such concepts of space and time without any precedent. What a great man. Well said! That he was as sharp as a razor blade is an understatement, he certainly understood what mathematics was saying to him when he tabled his general theory of relativity.

Yep, he is a regular Einstein. Oh wait. :laugh: Really is remarkable. Link to comment Share on other sites More sharing options...
Zain Adeel Posted May 8, 2011 Share Posted May 8, 2011 that is exactly what i think... His paper.. and pencil.. and look how accurately he got it sitting in his Room. such imagination to begin with. Now... with all the computer power. All the new probes. And we are just proving them instead of finding an even better theory that can be proved!

DocM Posted May 8, 2011 Author Share Posted May 8, 2011 Einstein has been surpassed in many ways, quantum mechanics being something he stronly resisted but is a major root of modern technology. But as regards relativity, his theories hold nicely. Link to comment Share on other sites More sharing options...
