National Institute of Standards and Technology (NIST) physicists have set a new world record for atomic clock stability using a pair of ytterbium-based timepieces. Stable down to quintillionths of a second difference between one tick of the clock and the next, the new system may prove invaluable in many areas of science, such as determining just how constant the fundamental universal constants really are, and helping in the search for dark matter.
