Messages to Extraterrestrial Intelligence (Meti) has a great ambition, and that's to reach out to the closest Earth-like exoplanet to our Solar System called, Proxima b.
The plan is to start a series of workshops and a crowdfunding to make the dream a reality. The non-profit organization said they'll be needing an estimated amount of US$1 million a year to make the transmitter work.
Experts say, the target is, by 2018 they have released laser or radio signals to Proxima b, which is in the orbit of Proxima Centauri, the nearest star from Earth just 4.25 light-years away.
The group of scientist from METI assumes there will be life forms on that planet. Thus, as part of their mission, they have to figure out what to say and how to say it in case extraterrestrials get the signals. Experts have begun studying mathematical laws and scientific hypothesis to be successful in this goal.
Researchers see great potential for the Drake equation. It is written by astrophysicist Frank Drake in 1961, which may be able to calculate how many civilizations are living in the vast universe. Using this equation, experts at METI may be able to have answers for their mission in contacting the nearest exoplanet.
However, not everyone agrees with this move. Experts like physicist Mark Buchanan and Stephen Hawking said that sending signals to the unknown may mean trouble for humanity. These civilizations may be more advanced than us, and sending out signals from Earth may be too risky.
Despite that, experts at METI believe that the benefits of reaching out to these civilizations outweigh the risks. For them, knowing our place in the universe is much more important. Though, it isn't the first time that humanity has sent messages to the void, METI plans to do it regularly and to reach a deeper part of space.
