Professor Stephen Hawking has warned that trying to make contact with aliens by calling out to the cosmos could invite disaster.
It comes as a scientist, leading plans to seek out ET, believes that one way he could convince advanced aliens that we’re an intelligent species by teaching them the rules of cricket.
But, if his critics are right, there is a chance that who or whatever picks up the signals will want to take us on – or even invade Lords.
Members of Seti (Search for Extraterrestrial Intelligence) are preparing for the next step in actively calling out to aliens – instead of just listening.
What is known as Active Seti will be under serious discussion this week at the annual meeting of the American Association for the Advancement of Science (AAAS) in San Jose, California.
Seti spokesman Dr Seth Shostak outlined methods being explored of conducting Active Seti within the next two years – including the possibility of nurturing an alien interest in cricket and rock music.
