cosmic rays

For a long time, the motion of the sun, moon and stars has been used to track time. Now engineers at the University of Tokyo have proposed a new method to accurately track time by using the universe, that is, using particle beams from cosmic rays. Above: a new ultra precise time synchronization technology uses cosmic rays. For most of us, the daily timing may be delayed by a few seconds, which won’t cause any major problems. But in more scientific, industrial and technological scenarios, nanosecond differences may be crucial….
