World-first nuclear clock prototype could outperform atomic clocks

World-first nuclear clock prototype could outperform atomic clocks   Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up GPS and the internet, among other things. Now, scientists have built and tested the first prototype nuclear clock. Atomic clocks keep time by counting the vibrations of certain atoms, which are extremely …
