QMI AGENCY - The discovery of 72 fast radio bursts from a galaxy about 3 billion light-years from Earth intrigues scientists around the world.
Some of them even assume that the signals could be created by an extraterrestrial life form.
Discovered for the first time in 2012 by a team from McGill University, these signals were analyzed using a powerful algorithm at the heart of the Breaktrough Listen project. This artificial intelligence program managed, by analyzing the data, to locate 72 repetitions of the rapid radio burst.
"It's a very powerful and extremely short signal of a thousandth of a second," said astrophysicist André Lamontagne of the Université de Montréal, in an interview with LCN yesterday.
"It's quite intriguing. It's only been a few years since we discovered this type of phenomenon. We know about a few dozen of these impulses extremely short and powerful, but this one is the only one that is repetitive, until proven otherwise, "continued the scientist, explaining the interest of this discovery.
MULTIPLE ASSUMPTIONS
Astronomers and astrophysicists study various theories to explain these signals, which passed approximately 3 billion light-years before reaching the Earth.
"One of the hypotheses is that it could be associated with extraterrestrial technology," said Lamontagne.
Specifically, the signals could come, accidentally, from a spacecraft powered by a solar sail bombarded with energy, which would let detectable emissions, "a bit like the tailpipe of your car".
"But there are several hypotheses considered. Personally, I would put extraterrestrial technology at the bottom of the list. I wish it was extraterrestrial, but I believe more or less, "added the astrophysicist. According to him, the signals could be due to a contact between matter and a neutron star or a black hole.
Be that as it may, there is every reason to believe that this galaxy will remain in the sights of radio telescopes for years to come.
"There is nothing more fascinating for any scientist (...) than a mystery. We must find the solution, "enthused André Lamontagne.
