e to communicate and it is most unlikely that we will get any result back within our human life time since humans only started to send messages to outer space in the 1970s.The first message that was attempted in 1974 by Frank Drake, he was the pioneer of the Search for Extraterrestrial Intelligence (SETI) Institute. Dr. Drakes message to the stars was beamed from the Arecibo radio telescope in Puerto Rico. It contained just 1,679 bits of information. It consisted of a rectangular grid that aliens could reconstruct to provide a crude diagram of the solar system and of a DNA double-helix molecule, along with a smattering of other information. (Chandler, 1999)A recent message that was sent to outer space utilized a similar concept. Yvan Dutil and M. Stephane Dumas of the Defence Research Establishment Valcartier near Quebec City constructed a 22 page message which included several pages about mathematics and basic physics, a few about biology and geography, a diagram, some basic data about our solar system and a request to the recipients to send back some information about the world they call home. (Chandler, 1999) The reason to send such data is that scientists believed that mathematics and science are the two universal languages that the aliens should be about to understand if their civilization is advanced enough.Attempts to detect radio signals began in the early 1930s when Karl Jansky constructed a radio telescope, which started to detect radio waves from outer space. (Sagan, 1997) However, until this point, with all the improvement of our technology, we still cannot find any signal received from another civilization. The detection of radio signals from space would indicate that the origin of life is not an extraordinarily unlikely event. It would prove that simple forms of life do generally evolve into complex and intelligent forms, as on Earth. The most likely case is that the message will be form a civilization which the ...
