Atomic clocks are the most specific timekeepers in the environment. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a continuous frequency, like numerous microscopic pendulums swinging in sync. The finest atomic clocks in the globe continue to keep time with this sort of precision that, if they had been working given that the starting of the universe, they would only be off by about 50 percent a 2nd currently.
