Is the Earth in a Vortex of Space-Time?

Posted by Zonk on from the pinwheel-pinwheel-spin-me-around dept.

da6d writes "Apparently, we'll soon know for sure.... NASA has announced in an article that '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.'" More from the article: "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."

    Read "A Brief History of Time" by Stephen Hawking. Since a car can not travel *at* the speed of light, the light emitted from the headlights will still shine.
