Why NASA Hid These Strange Spheres in Orbit for So Long?
Six hundred miles above Earth, a remarkable satellite orbits in perfect silence. Inside its chambers, cooled to near absolute zero, four spheres float in a vacuum, spinning thousands of times per minute. They are the most perfect objects ever created by human hands – if one were enlarged to the size of Earth, its tallest mountain would stand just eight feet high.
The satellite maintains its position with bursts of helium gas just one hundredth the force of a human exhalation of the type of “puff” used to clean a pair of spectacles. Its telescope locks onto a distant star with a precision equivalent to spotting a human hair from a hundred miles away.
But this engineering marvel isn’t measuring anything we can see. Instead, it’s detecting something far more elusive – tiny distortions in the very fabric of space and time itself, distortions so minute that many scientists believed they could never be measured
