Do you think there are other intelligent beings in the universe? Are we alone in this universe? It is a big question of debate from centuries ago. The search for extraterrestrial life is one of the exciting issues of science. Almost every scientist believes there must be life beyond our earth. Because the universe is so vast. In this vast universe, there are a lot of galaxies and planets. And there are many planets in the universe which are habitable. There are many reasons for believing in Extraterrestrial Life. Some theories which can lead to Extraterrestrial Life are:
Drake Equations: In 1961, Frank Drake made an equation to search for extraterrestrial life. It helps to organize the search for the existence of life beyond Earth. The Drake equation is:
N=R×fp×ne×fl×fi×fc×L
It helps to summarize the effect of radio communications with aliens. It creates a roadmap to find intelligent life.
The Copernicans Principle: This is a psychological theory that suggests we aren’t alone in this universe. Humans are not only special or unique beings. There must be other life in another universe that may be more intelligent than human beings.
Fermi Paradox: According to Fermi Paradox, the universe is so vast and old but we haven’t encountered aliens yet. It means aliens are avoiding us or they exist but we cannot find them.
Habitable Zone: The scientists found many exoplanets that can be habitable. Research said that many planets have environments like our one. On those planets, there may be the existence of life. These lives can be more intellectual than ours or less intellectual than others.
These theories lead to the existence of aliens in the universe. There are so many exciting facts about aliens. Some people believe that scientists have already found aliens. But they aren’t revealing it for security purposes. Some people say that they watched UFOs and saw another world with life. But most of them are only fantasy or just a false story made by people. Let’s see some interesting facts that lead to extraterrestrial life:
Wow! Signal: Wow! signal is a strong radio signal which was detected on 15 August 1977. Its origin is still a mystery. Many scientists believe that it may be the radio signal that was sent by extraterrestrial life. But there is no clear evidence of who sent the signal.
UFOs: Unidentified Flying Objects are common news for people. Especially during the 20th century, this issue is very famous. Many people claim to see UFO’s. You can see many images of UFO’s on the Internet also. But it is said that these kinds of incidents can be caused by clouds, birds or balloons. Or maybe people are thinking man made drones and objects as UFO’s.
Area 51: Area 51 is a place situated in the USA where the public can not enter. It is the basement of the US Air Force in Nevada. But people believe that the government researches aliens and talks with them there. They claim that they saw UFO’s in that area. Area 51 is doubted to be a place for aliens because of its high security. But there is no ultimate truth behind there being any aliens.
So, the people of Earth still don’t find any extraterrestrial life. But it is not impossible to find them. Because the universe is so big and full of galaxies, stars, and planets. Scientists have already found some planets where the creation of life is possible. It is not so far to find this life. But a big question arises here. If there is any other life beyond our earth and if these lives are more intelligent than ours then why they still didn’t contact us? Are they afraid of us? Or have they gone so far in innovation that they don’t need us? So, the search for extraterrestrial life has been a mystery for mankind for decades.
