The fastest thing ever ... NASA's Parker Solar Probe -- which is flying around the sun collecting data -- just broke the record for being the fastest object ever to be created by human hands. The Parker Solar Probe is trucking through the galaxy at a speed of 394,736 miles per hour. At that speed, here on Earth, it would zip around the world about 15 times in a single hour -- or zoom from New York to Los Angeles in about 20 seconds. Not too shabby.
