Neutrinos send wireless message through the Earth
Just as neutrinos look likely to lose their faster-than-light crown, these subatomic particles have a new claim to fame as part of a wireless communication system that could potentially send messages directly through the Earth’s core.
A team at Fermilab in Batavia, Illinois have successfully used a beam of the near-massless particles to transmit the word “neutrino” to a detector 1 km away, including a 240-metre journey through solid rock.
Neutrinos rarely interact with other forms of matter, so pass through most objects unimpeded - including the Earth’s core. That makes them potentially useful as messengers. Previous suggestions include using these ghostly particles to send messages across the planet without wires, cables or satellites, to communicate with hidden submarines or even to sync alien clocks. This latest experiment is the first demonstration that the principle actually works…
