Is it Risky for Earth to Send Signals to Extraterrestrials?
For decades, scientists have used radio telescopes to listen for cosmic signals that could originate with an extraterrestrial civilization. Increasingly, they’re also broadcasting messages to the stars in hopes that someone is listening. But in a new interview with The Times, University of St. Andrews astronomer Martin Dominik cautioned against sending messages into the unknown of deep space. “Maybe,” he told the paper, provocatively, “they will come and eat us.”
“Anyone can just beam messages into outer space, and nobody has any right to stop them from doing it,” Dominik told The Times. “Some people feel uncomfortable about it. For the first time astronomers are facing an ethical question. Should we send messages out to others? Is this dangerous? Should we keep a lower profile? What is the better strategy?”
