“One can answer by saying intelligence is very rare, but then it needs to be tremendously rare. In a previous study, titled “ That is not dead which can eternal lie: the aestivation hypothesis for resolving Fermi’s paradox“, Sandberg and his associates proposed that the Fermi Paradox arises from the fact that ETIs are not dead, but currently in a state of hibernation – what they called “aestivation” – and awaiting better conditions in the Universe.Īs Dr. Sandberg is no stranger to the Fermi Paradox, nor is he shy about attempting to resolve it. Mathematically, this is expressed as: N = R * x f p x n e x f l x f i x f c x Lĭr. This equation states that the number of civilizations ( N) in our galaxy that we might able to communicate can be determined by multiplying the average rate of star formation in our galaxy ( R *), the fraction of those stars which have planets ( f p), the number of planets that can actually support life ( n e), the number of planets that will develop life ( f l), the number of planets that will develop intelligent life ( f i), the number civilizations that would develop transmission technologies ( fc), and the length of time that these civilizations would have to transmit their signals into space ( L). Based on hypothetical values for a number of factors, this equation has traditionally been used to demonstrate that – even if the amount of life developing at any given site is small – the sheer multitude of possible sites should yield a large number of potentially observable civilizations.

The Drake Equation, a mathematical formula for the probability of finding life or advanced civilizations in the universe. The study was jointly-conducted by Anders Sandberg, a Research Fellow at the Future of Humanity Institute and a Martin Senior Fellow at Oxford University Eric Drexler, the famed engineer who popularized the concept of nanotechnology and Tod Ord, the famous Australian moral philosopher at Oxford University. The study, titled “ Dissolving the Fermi Paradox“, recently appeared online.
But in a new study conducted by three famed scholars from the Future of Humanity Institute (FHI) at Oxford University, the paradox is reevaluated in such a way that it makes it seem likely that humanity is alone in the observable Universe. In the decades since Enrico Fermi first posed the question that encapsulates this paradox (“Where is everybody?”), scientists have attempted to explain this disparity one way or another.
Named in honor of the famed physicist Enrico Fermi who first proposed it, this paradox addresses the apparent disparity between the expected probability that intelligent life is plentiful in the Universe, and the apparent lack of evidence of extra-terrestrial intelligence (ETI). The Fermi Paradox remains a stumbling block when it comes to the search for extra-terrestrial intelligence (SETI).
