Aliens on Earth true or false

Aliens

The encounter with another intelligent civilization would have such an impact on humanity that is difficult to calculate their consequences. It would not only transform our culture and technology, but it will possibly change the way in which we understand the depths of the human being, our origin and our destiny. However, are we prepared to respond appropriately to a salute so extraordinary? In the 1990s, the international community agreed a 'detection Protocol' laying down the steps to be followed in case of an extraterrestrial contact. Now a year, scientists from distinguished universities signed an article in a scientific journal of the British Royal Society in which warned the Governments of the world of the need to work more in these response plans, especially if the visitors are violent. But the debate over how to handle tremendous encounter is not new. Alan Penny, of the University of St. Andrews, in Scotland, has recently published the history of an actual incident which occurred in 1967 in which was considered seriously the possibility of contact with extraterrestrial civilizations in arXiv.org.

It happened when the Cambridge Observatory astronomers discovered pulsars, rotating neutron stars that produce pulses of radio. The team that made the discovery was led by Anthony Hewish, who later received the Nobel Prize for the work. The scientists, who had never seen anything like were so amazed that for a few weeks, team members considered the possibility of signals were generated on a planet orbiting around a distant star, and that those signals had an artificial origin, which were generated by what they called "Green little men" (Little Green Men or LGM).

Regular signals were in the same position in the sky each day. During the following months, appeared three sources of regular signals. By then, scientists already ruled out that they had an artificial origin. They were neutron stars. The find was announced in February 1968 and was published in the journal Nature.

Give an answer

But until not be ruled out, according to the documentation collected by Penny, the team discussed what to do if it was from an artificial source, how to verify this conclusion and how to announce it. It even argued about whether discovery could be dangerous and if I was going to respond to the signals.

In this way, according to the author, team has had moved forward to some components of the Protocol established in the SETI search for extraterrestrial intelligent life programme and other established protocols twenty years ago. Penny warns that the international community has yet to agree on what that response should be.

Currently, there are opposing views on how to react. Some scientists, including famous Stephen Hawking, believe that it is better to avoid contact at all costs, because if aliens come here it is possibly not only for a coffee and have a nice chat, but to "conquer and colonize". In his view, visited by aliens our planet would have the same effect as Cristobal Colón upon his arrival in America. However, SETI and NASA are more than willing to reach out to strangers. As I have said on some occasion, «not we can hide always under a rock".

The search for exoplanets gives increasingly larger fruits, so perhaps the idea of knowing how to respond to a «Hello» space be something reasonable.
