For many years, people have been wondering if there is life in other planets. With the universe so vast, the chance that there is life in other planets is still very likely. For alien communication, scientists hope to send "hello" to space for a reply from extraterrestrials.
A group of scientists intend to send greetings to space first more than anything else. This is to hopefully start conversations with those who might be listening for us. The group is called Messaging Extra Terrestrial Intelligence or METI.
The first targeted planet would be Proxima b, a planet that has recently been identified to have a possibility of life in it. Proxima b orbits Proxima Centauri. The planet is said to be at the Goldilocks area where life can be possible. Proxima b would be the first of what is expected to be a regular broadcast to send messages.
Douglas Vakoch is the President of METI and also the former director of Interstellar Message Composition said that the effort is to start an exchange with extraterrestrials that would span generations. The project aims to send messages repeatedly to targeted planets. This would take months or even years.
The project hopes to have a response coming from the target planets. METI has just been started last year and is aiming to have workshops by 2017. The workshops would be held in Paris and St. Louis, according to Phys Org. It also hopes to raise money for staff and build a transmitter that could send messages from a remote location.
There are some who are opposed to sending messages into space however. Renowned theoretical physicist Stephen Hawking has said that it's not certain whether the extraterrestrials contacted might be hostile or not. This is also the thought of physicist Mark Buchanan, as The Sunday Morning Herald reports.
Others though are a bit more encouraging, though they say that people on Earth should first learn how to converse with extraterrestrials before sending out messages. Alien communication might not be easy, but scientists to send "hello" to space for a reply from them. Scientists might have found alien signals, as deep space radio waves are detected.
