Stephen Hawking warned that extraterrestrial messaging was a really terrible idea – similar to a sign saying "ATTACK HERE".
But MIT scientists say we could use existing laser technology to create a "lighthouse". could be seen by extraterrestrials up to 20 000 light years
The researchers suggest that if we focus a very powerful laser using a large telescope (up to 147 feet), it would be visible to extraterrestrial astronomers (even among the radiations) of our sun).
If extraterrestrial astronomers detected the signal, we could also use it to send a message in Morse code, says MIT scientist James Clark.
Clark says, "If we managed to close a handshake and start communicating, we could send a message, at a rate of a few hundred bits per second, that would arrive there a few years. & # 39;

Clark suggests that the laser / telescope could be built on the moon – to avoid
Clark says, "I wanted to see if I could take the types of telescopes and lasers we are building today and make them a detectable beacon. [19659002] & # 39; In general, it was a feasibility study. Whether or not it's a good idea, it's a discussion for future work.
Professor Stephen Hawking was a fierce opponent of attempts to " message "or direct contact with strangers.
Professor Hawking thinks it's a terrible idea, because all the extraterrestrials sophisticated enough to receive our message and travel here might well crush us without mercy.
He said: "If aliens visit us, the result would be much more similar to the one where Columbus would have landed in America, which has not worked well for Native Americans. & # 39;
