On the query of the existence of alien life, science fiction creator Arthur C. Clarke made this philosophically trenchant quip: “Two prospects exist: both we’re alone within the Universe or we aren’t. Each are equally terrifying.” One may substitute the phrase “astonishing” or “overwhelming” for “terrifying,” however I suppose that will depend on whether or not you simply watched 2001, The Quiet Earth, or Mars Assaults. The query of why precisely we haven’t encountered any interstellar neighbors is phrased this fashion on Sci-Fi Interfaces:
“With 400 billion stars in our galaxy, and 400 billion galaxies within the observable universe, and billions of years of time for the reason that begin of the universe, even when solely a really small fraction of stars produced superior civilizations, the place…is everyone? Why does area appear so devoid of life?”
That query is usually known as “The Fermi Paradox,” despite the fact that it isn’t actually a paradox, within the conventional sense. Sci-Fi Interfaces explored the Fermi Paradox in relationship to science fiction in a latest publish. Right here’s extra from Sci-Fi Interfaces:
About eleven years after Fermi requested his query, an astrophysicist named Frank Drake created a probabilistic equation by which we may give you some reply about what number of civilizations we’d anticipate finding on the market within the void. Now this isn’t like most equations for which you count on to get a single reply. This equation hopes to get us a minimum of within the ballpark of the proper proper reply, say to an order of magnitude inside the precise one. Simply so we are able to know whether or not we’re speaking about 10, 100, or 1,000 civilizations, and many others. Drake’s equation has seven variables which we multiply collectively to provide a solution.
