Physicists have created ultra-precise watches that work on atoms strontium. The uniqueness of these chronometers is that two their copies can be out of sync for 1 second only after 16 billion years.
A new watch is a thousand times more accurate than atomic devices cesium and until recently considered the most faithful. Recall time in an ordinary mechanical watch is measured by oscillations of the pendulum, and in atomic counterparts – due to oscillations atoms.
Strontium clocks can be used to measure gravitational time dilation. It is known that as you delete from Earth, the passage of time accelerates. How much This will help identify ultra-precise watches.
