Scientists from the Future of Humanity Institute at Oxford University have revealed that we are probably the only advanced civilization out there, although they can’t say for sure. The team came to their conclusion after realizing that Fermi’s paradox and its supporting theories are somewhat flawed. The paradox is the conflict between the probability that intelligent life exists elsewhere in the universe and the lack of evidence of such.
When people discuss the [Drake] equation it is not uncommon to hear them say something like: ‘this parameter is uncertain, but let’s make a guess and remember that it is a guess,’ finally reaching a result that they admit is based on guesses,” Dr. Anders Sandberg, one of the study’s authors, told Universe Today.
“This often leads to overconfidence, and worse, the Drake equation is very sensitive to bias: if you are hopeful a small nudge upwards in several uncertain estimates will give a hopeful result, and if you are a pessimist you can easily get a low result.”
