Physicists have unveiled the world’s most accurate clock — a timepiece so reliable that it would take more than 260 billion years to lose a second.

Precision clocks are used in everything from satellite navigation to looking for dark matter. Ever more accurate clocks open fresh opportunities, such as mapping changes in Earth’s gravitational pull with exquisite precision, and could form the basis of a new definition of the second.

So, every second, there are about 100 trillion neutrinos and tens to hundreds of muons passing through your body per second, and maybe a tiny scattering of neutrons and other cosmic particles or debris from cosmic particles impacting the atmosphere.
