For many centuries, scientists have asked whether mankind is alone in the universe, but so far has not found conclusive evidence. The huge size of outer space suggests that life necessarily exists elsewhere, but all the ways to detect it still have not yielded results.
However, experts at Breakthrough Listen, an organization that scans stars in the hope of finding alien signals, believe that extraterrestrial life exists. So, for example, this was confirmed by Lee Spitler, an astronomer at Macquarie University in the program “Trust Me, I am an Expert.”
Danny Price, a scientist at Breakthrough Listen, is also confident that they will “find something”, but admitted that it may take some time. Here is what he reported:
“There is little chance that we will find anything – I think this is a long-term human mission. This is what we need to continue to do.”
There are several scientific equations that determine the likelihood that we are not alone in the universe, for example, the Drake equation. In 1961, scientist Frank Drake invented an equation describing the variables and the chances of an alien civilization in the universe, taking into account factors such as the rate of formation of stars suitable for the development of life on surrounding planets and the number of planets per solar system.
Despite the fact that so far there is no single solution for the equation, it indicates that there are impressive chances for finding life in space. One possible solution to the equation is that alien life once existed, but died out before life appeared on Earth. Another solution is that the Earth is the only place where life could evolve in the universe.
There is another way to look at the problem of finding aliens – this is the Fermi paradox. In 1950, physicist Enrico Fermi (creator of the world’s first nuclear reactor). The scientist came up with a paradox that says that due to the age and size of the universe, civilization will inevitably be much more developed, and casts doubt on the question “Are we alone?”
Many scholars argue that the solution is that when civilization reaches a certain size, it ultimately kills itself either by war with the latest weapons, or by natural disaster. Some experts, however, had previously cautioned against trying to contact any reasonable species.
Even Stephen Hawking, who died in March 2018, suggested that contact with aliens could be risky. An example in his last book talked about how Europeans clashed with Native Americans and almost destroyed them completely in order to conquer the New World.
