A space-time vortex right underneath Earth

...And every other rotating mass in space apparently.  According to a recent NASA experiment (which required building "the most perfect spheres ever made by humans"), Einstein's predictions that under all spinning objects of a large mass, space-time gets twisted (imagine a fat man in a trampoline rotating in his place) by the motion.  This constant twisting creates a space-time vortex!



For this experiment and the extreme precision it required, NASA had to invent 13 new technologies to succeed and began funding this research since 1963!
