i have researched it, and in 2005 NASA said they sent a probe the rotate the earth to see if Einstein's theory was true (about the 4D space time vortex that the earth put a dent in). i just cant seem to find the results anywhere... NASA said it would take a year to figure it out and that was in 2005. 5 year later and i cant find any sources on the result. any help would be appreciated!
