Astronomers always dreamed of contacting Extra Terrestrial beings living outside or even beyond our planet.
This question has been actively debated in the last years. Is there is a planet with similar conditions as the ones we have on Earth that allows other intelligent life forms to live on it? In the last 50 years, scientists had tried and failed to find the answer to such questions. while most of them have reached the conclusion that ETs do not exist.
The current human approach on contacting aliens is based on tracking radio signals from alien civilization. Some astronomers have suggested that humans should take the initiative and try to actively reach our galactic neighbors.
The scientists say we could discover a mean though which to send messages in the direction of the closest stars in our galaxy. A scientist from the SETI institute, which covers the Search for Extra Terrestrial Intelligence, proposed the concept at the annual meeting of The American Association for the Advancement of Science, as part of a program called Active SETI.
Douglas A. Vakoch, the director of SETI’s interstellar message composition, explained that we should get a response from aliens if we let them know that we want to make contact. Vakoch thinks that this may be the optimal strategy to make contact with an alien civilization, adding that people should control their fears and uncertainties, while concentrating on the brighter side of the issue: the amazing experience of getting in touch with aliens.
Seth Shostak, the director of the Center for SETI Research, suggested that we could send the content of the internet into the outer space. Such a large amount of videos, texts, sounds and pictures could offer the aliens a chance to understand many things about our society. It would not be such a bright idea to use a radio transmitter, because it would take to much time, about a month for the entire web to be released into space. The scientists want to use a more efficient laser which can transmit bits. The data can be sent entirely in just a few days.
SETI’s plans were not welcomed by everyone present at the meeting. Other scientists believe that such exposure could prove to be very risky for humanity. Dr. Seth Shostak answered the critics by saying that if the plan were to be put in practice it would be as if you were screaming in a jungle without knowing what will come out from the bushes.
