American astronomers have estimated the likelihood of intelligent extraterrestrial civilizations in our galaxy, and the findings of their research determine that there is at least one, according to their study published on the arXiv.org website.
Luis A. Anchordoqui, Susanna Weber and Jorge F. Soriano, of the University of the City of New York (USA), have pointed out that it must be taken into account that not all habitable planets can harbor intelligent life and that the Average time of existence of extraterrestrial civilizations can vary greatly depending on galactic disasters such as gamma ray bursts, supernova explosions and other factors that can destroy life on those planet before we discover them.
Fascinating!
