Moving multiple metronomas all at once will move apart at first, but eventually all the metronomes will interact with each other and tick the sound at the same timing .... The phenomenon called ...

Scientists have set up the world's most precise 'metronome' for a kilometer-wide network. The timing system synchronizes a 4.7-kilometer-long laser-microwave network with 950 attoseconds precision. An ...
