Alien study reveals 36 civilisations may be trying to contact Earth - but we're not ready
UP TO 36 alien civilisations could be beaming radio signals across the Milky Way in a bid to make contact, a bombshell new study has revealed.
Although there has been no evidence of aliens, a new study has revealed many advanced aliens could be sending communication signals across the cosmos. The research from the University of Nottingham is based on how likely intelligent life is to evolve on other planets, based on our own evolution. According to the study, intelligent life able to broadcast signals would evolve at an average distance of 17,000 light-years from one another.
This would mean that up to 36 advanced civilisations could exist in the Milky Way.
However, experts at the University of Nottingham believe that Earth and its population are not yet advanced enough in technological terms to receive these signals, according to the study published in The Astronomical Journal.
Professor Christopher Conselice, an astrophysicist at Nottingham, explained: “I think it is extremely important and exciting because for the first time we really have an estimate for this number of active intelligent, communicating civilisations that we potentially could contact and find out there is other life in the universe – something that has been a question for thousands of years and is still not answered.
"There should be at least a few dozen active civilisations in our galaxy under the assumption that it takes five billion years for intelligent life to form on other planets, as on Earth.
"The idea is looking at evolution, but on a cosmic scale. We call this calculation the Astrobiological Copernican Limit."
The Astrobiological Copernican Limit has two assumptions based on what is known about intelligent civilisations on Earth.
One is that the planet must be in the habitable zone of its star - the area where it is neither too far nor too near to the star.
The other is that the planet would need to be between 4.5 and 5.5 billion years old - much like Earth is.
