This week, famed physicist Stephen Hawking helped launch a significant new effort to seek for indicators of clever alien life within the cosmos, despite the fact that he thinks it is doubtless that such creatures would attempt to destroy humanity.
Since at the least 2010, Hawking has spoken publicly about his fears that a sophisticated alien civilization would don’t have any downside wiping out the human race the way in which a human would possibly wipe out a colony of ants. On the media occasion announcing the new project, he famous that human beings have a horrible historical past of mistreating, and even massacring, different human cultures which are much less technologically superior — why would an alien civilization be any totally different?
And but, it appears Hawking’s need to know if there may be clever life elsewhere within the universe trumps his fears. At this time (July 20), he was a part of a public announcement for a brand new initiative known as Breakthrough Pay attention, which organizers stated would be the strongest search ever initiated for indicators of clever life elsewhere within the universe.

The brand new Breakthrough Pay attention initiative would solely seek for indicators of clever life, not broadcast alerts from Earth, and scientists apart from Hawking have expressed concerns about hailing the eye of alien civilizations. Nonetheless, a second initiative, Breakthrough Message, will host a contest open to anybody on this planet, to make options for the content material of messages to be despatched from people to different clever beings.
Scientists at present do not know what alien life-forms would possibly appear like, or how they may reply to contact from human civilization.
“Such superior aliens would maybe turn into nomads, trying to conquer and colonize no matter planets they may attain,” Hawking said in 2010 on an episode of “Into the Universe with Stephen Hawking,” a TV present that aired on the Discovery Channel. “In that case, it is sensible for them to take advantage of every new planet for materials to construct extra spaceships so they may transfer on. Who is aware of what the boundaries could be?”
Hawking voiced his fears on the Breakthrough occasion, saying, “We do not know a lot about aliens, however we find out about people. If you happen to take a look at historical past, contact between people and fewer clever organisms have usually been disastrous from their standpoint, and encounters between civilizations with superior versus primitive applied sciences have gone badly for the much less superior. A civilization studying one among our messages may very well be billions of years forward of us. In that case, they are going to be vastly extra highly effective, and will not see us as any extra precious than we see micro organism.”
Astrophysicist Martin Rees countered Hawking’s fears, noting that a sophisticated civilization “might know we’re right here already.”
Ann Druyan, co-founder and CEO of Cosmos Studios, who was a part of the announcement panel and can work on the Breakthrough Message initiative, appeared way more hopeful in regards to the nature of an advanced alien civilization and the way forward for humanity.
“We might get to a interval in our future the place we outgrow our evolutionary baggage and evolve to turn into much less violent and shortsighted,” Druyan stated on the media occasion. “My hope is that extraterrestrial civilizations aren’t solely extra technologically proficient than we’re however extra conscious of the rarity and preciousness of life within the cosmos.”
Jill Tarter, former director of the Heart for SETI (Search for Extraterrestrial Intelligence) additionally has expressed opinions about alien civilizations which are in stark distinction to Hawking’s.
“Whereas Sir Stephen Hawking warned that alien life would possibly attempt to conquer or colonize Earth, I respectfully disagree,” Tarter stated in an announcement in 2012. “If aliens had been to return right here, it might be merely to discover. Contemplating the age of the universe, we most likely would not be their first extraterrestrial encounter, both.
“If aliens had been in a position to go to Earth, that might imply they’d have technological capabilities refined sufficient to not want slaves, meals or different planets,” she added.
The brand new Breakthrough Pay attention initiative is scheduled to function for 10 years and can seek for indicators of non-naturally occurring communications in each radio frequencies and laser transmissions. The initiative will scan the 1 million stars closest to Earth within the Milky Manner, in addition to the 100 closest galaxies.
