Let us all — wherever and whenever — live on what the world’s timekeepers call Coordinated Universal Time, or...

New optical clock is most accurate ever built

Scientists have come up with a clock so accurate that it could even redefine the length of a second. Currently, time is measured on the idea of a pendulum, or in the case of an atomic clock, the natural back-and-forth rhythm of a caesium atom. Similarly, the length of a second is defined as the time that passes during 9,192,631,770 cycles of the microwave signal generated by this process. There is however another, more accurate, way of keeping time. The optical clock, which unlike regular atomic clocks works using strontium atoms in place of caesium, operates at the visible, as...
