195 1 year, Fermi paradox makes people feel sad, because Fermi paradox tells people that there are two possibilities for the existence of alien civilization: aliens exist, and their evolution is much earlier than human beings, so alien civilization should have come to earth and existed somewhere.
However, if there is an advanced extraterrestrial civilization in the Milky Way, why can't you even see evidence such as spacecraft or detectors? Fermi paradox also points out the possibility that aliens do not exist. This theory is undoubtedly a blow to scientists who believe in alien civilization, and it is also unacceptable to many scientists.
Later, people made various explanations for Fermi paradox. Some scientists believe that the reason why human beings have not discovered alien civilization so far is because the cosmic civilization has been eliminated by the natural laws of the universe after it has developed to a certain stage. This statement is hard for human beings to accept, just like throwing cold water on people. After years of efforts to explore alien civilizations, human beings suddenly told us that human beings will disappear one day.
This statement is not unreasonable. In Liu's Three-body, the law of the dark forest has been expressed. He compared our universe to a dark forest. There are all kinds of cosmic civilizations in this dark forest, and each civilization is trying its best to hide its position, otherwise it will lead to fatal disaster once it is discovered.
This dark forest law, like the natural law of the universe, can also explain why humans have not found any trace of alien civilization so far. In addition, Hawking also told mankind not to provoke alien civilizations before his death, otherwise mankind will face disaster.
Fermi paradox also seems to imply the future of human development, so what do you want to say about alien civilization? Welcome everyone to leave a message in the comments section.
