The World’s Most Precise Clock Keeps Time Within Quadrillionths Of A Second

An international team of physicists have created a new atomic clock, which is capable of measuring time down to a couple quadrillionths of a second. Even though atomic clocks have been around since 1948, never before has one been so insanely accurate. The clock is powered by strontium atoms packed into a tiny cube at 1,000 times the density of previous atomic clocks. The ultra-increased density allows scientists to use ultra-stable lasers to utilize the 'quantum gas' and create a practical measurement device. This results in the most steady metronome ever created, which ticks at a rate that is six times more accurate than the previous record-holder.
