Even if planets capable of sustaining life are exceedingly rare, on the numbers alone there should be intelligent life somewhere in the universe. For example, according to Business Insider, if a mere 0.1 percent of planets in our galaxy that might be habitable harboured life, that would mean there were about a million planets with life on them. These numbers prompted Nobel Prize-winning physicist Enrico Fermi to ask in regard to alien life forms: “Where are they?” This question has come to be known as the Fermi paradox, and most possible answers to it would be concerning for humans. Of particular concern is the “Great Filter” hypothesis, which posits that before intelligent life has the opportunity to escape the bounds of its original planet, it hits some sort of wall – the Great Filter. There are certain transitional moments from an evolutionary perspective that any planet like ours would have to master before communicating with other worlds.…
