Space-time Vortex

has gathered all the data physicists need to check a bizarre prediction of Einstein's relativity.

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. The results, which will take another year to analyze, should reveal the shape of space-time around Earth--and, possibly, the vortex.
Time and space, according to Einstein's theories of relativity, are woven together, forming a four-dimensional fabric called "space-time." The tremendous mass of Earth dimples this fabric, much like a heavy person sitting in the middle of a trampoline. Gravity, says Einstein, is simply the motion of objects following the curvaceous lines of the dimple.

If Earth were stationary, that would be the end of the story. But Earth is not stationary. Our planet spins, and the spin should twist the dimple, slightly, pulling it around into a 4-dimensional swirl. This is what GP-B went to space to check

Thanks SirUlli! I liked this article very much. 😀

Thanks, SirUlli, for this and your recent other sci posts.

Very much appreciated!

I live in New York City and always made it a point to get the NYT's on Tuesday (Science section) and Thursday (Health & Medicine section) - that is - until I could not stand their Leftist leanings and decided to vote with my wallet and discontinue the purchases. The old man (who's son runs the paper now) is surely spinning in his grave!

Sorry about the political rant, I know it belongs at the other forum under Anandtech for politics (I recently stuck a tentative toe into that forum recently - Ugh! - talk about feeling unclean!)
