You may have thought that the previous world's most accurate clock was good at keeping time, but it's apparently nothing compared to this new strontium atomic clock developed by scientists at the University of Colorado, which is supposedly more than twice as accurate and just as atomic. To achieve that impressive feat, the scientists made use of the same so-called "pendulum effect" of atoms as before, but took things one step further by holding the atoms in a laser beam and freezing them to almost -273 degrees Celsius, or the temperature at which all matter stops resonating. In clock terms, that translates to about one second lost every 300 million years. Of course, that's still one second too many for the researchers, and they say they "dream of getting an atomic clock with perfect precision." You just know you never want to be late for a meeting with these guys.
