![]() Here we see it from an orbiting rocky planet, recently discovered, called Proxima b. It is a dim red dwarf, smaller than our Sun and many. However, Siraj and Loeb point out that humans appeared on Earth before Alpha Centauri‚ which Prima Centauri orbits-was our nearest star system. It’s suspected that Scholz’s star-a red dwarf star now 22 light-years from us “grazed” the Solar System about 70,000 years ago, coming within a single light-year. 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.
