The device, which traps thousands of atoms to keep time, is "pushing the boundaries of what's possible with timekeeping." The device traps thousands of atoms to keep time, and is "pushing the boundaries of what's possible with timekeeping."

      Standard seconds are defined based on measurable properties of a cesium atom. The historical definition of 1/86400th of a day doesn’t work for science if the duration is inconsistent.

      For example the statement:

      Earth’s Days Are Getting 2 seconds Longer Every 100,000 Years

      becomes self-referencing and loses all meaning without some other reference point.

        “I suppose”.

        Boom, now it’s a scientific unit.
