  • user The Fermi Paradox With Neil deGrasse Tyson - Where Are All The Aliens?

    The Fermi Paradox is the apparent contradiction between the high probability of extraterrestrial civilizations existing and the lack of evidence supporting their existence. In the video, Neil deGrasse Tyson discusses the search for extraterrestrial life, the advancements in technology that have aided in this search, and the possibility of life on other planets. He notes that the prevalence of life in the universe may be a quantifiable entity, with the stock in the prevalence of life having gone up due to the discovery of exoplanets and biosignatures. Tyson also discusses how the timeline for the formation of life on Earth has shrunk, making it more likely that life could form given the right conditions. However, he notes that there is currently only one data point for the existence of life in the universe, and that evidence for the existence of intelligent alien life would be one of the biggest scientific discoveries of all time.
