The Fermi Paradox is really an argument based off of empirical evidence that there is extraterrestrial life out there, despite the extreme lack of evidence. It is named after physicist Enrico Fermi, who in 1950 mentioned the idea while out for a lunch with coworkers, having casual conversation. They started talking about their UFO reports and Fermi exclaimed “Where is everybody?” Everyone laughed nervously. After that Michael H. Hart who wrote a paper and formulated and examined the paradox in 1975. The argument covers not only the fact that there is extraterrestrial life out there, but also why they haven’t communicated with us.
They base their beliefs off of several observations. They believe that the scale of space is so large, even infinite.The large scale combines with the high probability that there is intelligent life out there because there are a billion planets and suns out in space and in the milky way. The probability is also high because of the frequency that intelligent life overcomes scarcity and colonizes new environments. This is also supported by various astronomer accounts of UFO’s Hart calculated the probability through Drake’s equation, which was formed in 1961 by Frank Drake to evaluate different probabilities of extraterrestrial life existing.
This equation led to many different results and was used by both sides of the argument. There are some probabilities that there could be up to 100,000,000 civilizations in the Milky Way, which is used by the optimists of the Fermi Paradox. However, some combinations show the probability of less than one civilization in our galaxy, which is taken advantage of by the pessimists of the paradox.
According to another physicist, human beings might not be ready for higher beings to contact us. Some explanations also mention that aliens have already contacted us and we haven’t been listening correctly and that they have already been to Earth. Others say that aliens might not have the technological advances to communicate with us or that they are too far apart from us in space and time. Studies are being done now to see if scientists can make an object travel at the speed of light, which could also be applied to space exploration
