uplne najklucovejsieho dokazu sa dockas vo februari az aprili 2007, ked sa ukonci tretia faza analyz takmer terabajtoveho baliku dat projektu Gravity Probe B. kukaj sem>> http://einstein.stanford.edu/

The experiment will check, very precisely, tiny changes in the direction of spin of four gyroscopes contained in an Earth satellite orbiting at 400-mile altitude directly over the poles. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are warped by the presence of the Earth, and, more profoundly, how the Earth's rotation drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe.

imho jeden z najkrajsich experimentov vobec :)
..cast o gyroskopoch je must.
