Experts Find NO EVIDENCE of Alien Life in Our Universe So Far, Could We Actually Be ALONE?
A team from the University of California Berkley examined light from 5,600 stars in our milky way – with almost a third of those thought to host Earth-like planets – and found that there is no evidence of alien life.
Humanity has become obsessed with the idea of finding life outside of Earth, but the biggest scan to date has drawn a blank.
The researchers were actually looking for high-powered laser beam emissions from nearby stars, which is thought to be a signature of a highly intelligent civilisation, but had no luck when analysing images from SETI (The Search for Extraterrestrial Intelligence) over a 12 year period.
Although the study was only of our galaxy, meaning that it was proportionately tiny, experts believe it could have huge implications in the search for aliens.
“We may have the universe all to ourselves”
All of the universe’s life may be here
The study published on arXiv read: “We found no such laser emission coming from the planetary region around any of the 5600 stars.
“As they contain roughly 2000 lukewarm, Earth-size planets, we rule out models of the Milky Way in which over 0.1 per cent of warm, Earth-size planets harbour technological civilisations that, intentionally or not, are beaming optical lasers toward us.”
Despite finding no evidence of aliens, the researchers cannot rule out the possibility of aliens being out there.
As previously stated, the researchers were looking for laser signatures, but a far away planet looking for laser signatures on Earth would not find any either.
This implies that the experts may need to alter what they are looking for.
Team member Nathaniel Tellis told the Atlantic: “Every single one of those stars could have a New York City, a Paris, a London, and we would have no idea.”
