NASA Gravity Probe Confirms Two Einstein Predictions

sanzibar writes "After 52 years of conceiving, testing and waiting, marked by scientific advances and disappointments, one of Stanford's and NASA's longest-running projects comes to a close with a greater understanding of the universe. Stanford and NASA researchers have confirmed two predictions of Albert Einstein's general theory of relativity, concluding one of the space agency's longest-running projects. Known as Gravity Probe B, the experiment used four ultra-precise gyroscopes housed in a satellite to measure two aspects of Einstein's theory about gravity. The first is the geodetic effect, or the warping of space and time around a gravitational body. The second is frame-dragging, which is the amount a spinning object pulls space and time with it as it rotates."

    Uh, what he said. I'd mod him up if I had any mod points. Not that I have had any for months, despite excellent karma. The new Slashdot: too buggy to be fit for purpose.

    why the fuck is this called get more comments? i'm guessing it actually refreshes for new comments, i was thinking it actually showed more of the truncated comments for this story like it does on every other fucking site.

    Totally off topic, I know, but I for one think it's a good thing that we can't mod stuff up so easily anymore.

    Good posts still get modded up (eventually), and you can use the slides to select the level you want to read. At least, the score is now a way to select the posts. It used to be a matter of just getting a post in quickly, which would get modded up simply because everybody had mod points. And to be read, you had to get 5 points.

    Now, good posts might have only 2-3 points. 4-5 points are excellent posts.
