Broadcasting Earth’s location could provoke alien invasion, Oxford scientist warns
Nasa's plan to beam Earth's location into outer space could provoke an alien attack, Oxford scientists have warned.
The US space agency has proposed broadcasting a message, dubbed the “Beacon in the Galaxy”, intended to greet extraterrestrial intelligences. It is an updated form of the Arecibo message, broadcast in 1974 for the same purpose.
Improvements in digital technology mean that more information can now be broadcast. The proposed new message includes basic mathematical and physical concepts to establish a universal means of communication, followed by information on the biochemical composition of life on Earth.
It also includes the solar system’s location relative to major clusters of stars, along with digitised depictions of the solar system itself, Earth’s surface, and male and female humans. The message concludes with an invitation for intelligences to respond.
