(ORDO NEWS) — Clocks and other electronic devices in different parts of the planet can be precisely synchronized in time using cosmic rays. This idea was put forward by geophysicist Hiroyuki Tanaka from the University of Tokyo.
Today, atomic clocks can keep accurate for decades, he said, but they are expensive and cannot synchronize clocks in remote areas. Synchronization by satellite signals also has problems in the regions of the poles, under water and in the mountains.
Tanaka proposed a new method – space time synchronization (CTS), based on the use of the so-called extensive air showers. They arise from cosmic rays entering the atmosphere.
These beams create a “shower” of various particles, including muons flying towards the earth at near-light speed and therefore reaching the earth at the same time. By fixing their arrival, CTS devices can synchronize with each other in real time.
“The principle is simple, and the technology, sensors and electronics already exist. So we can implement this idea quite quickly,” the author believes.
According to him, clocks can be synchronized throughout the planet in this way, since showers of particles occur frequently – on the order of a hundred times per square kilometer of the surface.
