The recent passing through the Solar System of interstellar comets such as 1I/’Oumuamua and 2I/Borisov could be evidence of that. Instead of discussing where life could have emerged independently we could consider the possibility that the seeds for life could have been spread in our random corner of the Universe by intergalactic comets-a process called panspermia. In fact, it violates the Copernican principle, which tells us that our technological civilization is a single outcome of a random process. It argues that a radio-transmitting civilization occupying the next star system along is just so hugely unlikely at eight orders of magnitude. Only one from Harvard University astrophysicists Amir Siraj and Abraham Loeb, which is published on non-peer-reviewed printspre-print hub arXiv. “It’s probably not alien and we will confirm this soon (but) nothing would please me more than to be proven wrong.” Have there been any scientific paper on BLC1? Marchis suspects a down-to-earth explanation for the signal’s origin. “Of the 300 million exoplanets that could be habitable in our galaxy, which is 200,000 light years across, it would be an astonishing coincidence for two civilizations-ours and one on Proxima b or c-to be using the same technology at the same time,” said Franck Marchis, a Senior Planetary Astronomer at the SETI Institute.
Healthy extreme scepticism is the best summary. It’s obviously the least likely reason for BLC1. It’s a message from a technologically advanced civilization living on one of the two planets known to be orbiting our nearest stellar neighbor.After all, space is big. So it may not be from a nearby star anyway. The radio signal is coming from behind Proxima Centauri-possibly millions of light-years beyond.The source is natural, but unknown-maybe it’s a really odd kind of quasar (a supermassive black hole) or pulsar (a highly magnetized rotating compact star) that emits narrowband radio signals.Extraterrestrial technology exists in space because we put it there-it could be from a satellite or a spacecraft.After all, it’s got all the hallmarks of being artificial and having a technological source. Since we use radio, it could well be interferences-the signal could have originated on Earth.
There are lots of opinions-and most of them suggest something other than you-know-what: Universal Images Group via Getty Images What do experts think the signal is? naked eye-close to Alpha Centauri, a star mostly visible from the southern hemisphere.
The Proxima Centauri star system is just 4.24 light-years from us and is found-though not with the. However, until scientific papers are published-something that is expected soon-the signal’s profile, strength and modulation remain unknown. It was also only detected once over 30 hours in April and May, 2019. It occupied the 982 MHz radio spectrum, which is normally used by satellites and spacecraft. What is strange about ‘BLC1?’īLC1 was a very narrow band radio signal.
However, BLC1 is not a dimming star, but a radio signal that appears to have a technological source. Was it an alien megastructure around the star periodically blocking its light? Probably not. Boyajian detected the mysterious dimming of a star called KIC 8462852-henceforth nicknamed “ Tabby's Star”-1,470 light-years distant in the constellation of Cygnus. The most recent conversation about technosignatures occurred in 2015 when astronomer Tabetha S. What form do they take? Nobody has a clue. “Technosignatures” or “technomarkers” are signs of technology developed by intelligent life elsewhere in the Universe.
