A new study from the Future of Humanity Institute (FHI) at Oxford University suggests that humanity is alone in the observable universe.
Conducted by Anders Sandberg, Eric Drexler, and Toby Ord, the study was named Fermi paradox after physicist Enrico Fermi.
The Fermi paradox is the contradiction between the lack of any evidence that Earth has been visited by intelligent extraterrestrial civilizations and the high probability that one or multiple civilizations exist, due to a number of factors.
The factors include evidence that there are billions of stars in the galaxy similar to our Sun with many of these stars having Earth-like planets. Additionally, some of these civilizations may have developed interstellar travel, something that is being discussed now by experts, including theoretical physicist Dr. Michio Kaku.
In this study, Sandberg, Drexler and Ord reconsidered the Drake Equation, looking at adding chemical and genetic transitions to it. They noted that by incorporating these into the equation, it brings up significant amounts of scientific uncertainties.
Sandberg further added that based on the equation’s parameters, they looked at the smallest and largest values they might have and came up with a probability of 30 percent that mankind is alone in the universe.
“We found that even using the guesstimates in the literature (we took them and randomly combined the parameter estimates) one can have a situation where the mean number of civilizations in the galaxy might be fairly high – say a hundred – and yet the probability that we are alone in the galaxy is 30%!,” he said. “The reason is that there is a very skew distribution of likelihood.”
Results of the study have drawn the attention of several experts, including SpaceX and Tesla CEO Elon Musk.
