The Fermi paradox !
August 23, 2020
The Fermi paradox seeks the answer to the question of where the aliens are. The Fermi paradox was named after the Italian physicist Enrico Fermi, who is famous for creating the first nuclear reactor. The Fermi paradox is the apparent contradiction between the lack of evidence for extraterrestrial civilizations.
Like many stars, as there are in our galaxy (100 – 400 billion), there is roughly an equal number of galaxies in the observable universe. For every star, there is a whole galaxy out there. As many as 6 billion Earth-like planets in the Milky Way galaxy. Enrico Fermi also estimated that there should be 10,000,000,000,000,000 intelligent civilizations in the observable universe. The answer to the Fermi paradox is unknown. The scientists could do is "possible explanations".
