A big hello to each of the 36 intelligent alien civilizations that may, possibly, be living in the Milky Way Galaxy with us
What are they trying to tell us?? Photo: Getty Images/iStockphoto At this point, it appears all but assured that we are not alone. I mean, the evidence is overwhelming: a quintet of cows, mysteriously sapped of all blood and surgically separated from their genitals? Sounds like aliens, according to the Cut and also the local sheriff’s deputy.
“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 civilizations that we potentially could contact and find out there is other life in the universe,” Christopher Conselice, a professor of astrophysics at the University of Nottingham and a co-author of research published Monday in the Astrophysical Journal, told the Guardian.
The current go-to calculation for ballparking Milky Way residents is the Drake equation, which identifies seven factors allegedly necessary to make an educated alien count. Yet the Drake equation provides no firm answers, so Conselice and colleagues tweaked it to account for certain ingredients crucial to the development of life on Earth — things like the presence of a metal-rich environment, and the likelihood that other stars may have Earth-like planets in their orbits.
It’s just one theory, and even if it did prove correct, we’d still be looking at a thousands-of-years wait before we can engage in a game of intragalactic telephone; Conselice suspects the closest aliens could live about 17,000 light-years away. Unfortunately, the way things are going, we probably don’t have that kind of time.
