Although science and technology are very developed today, there are still some mysteries that we don’t know, such as whether there are alien creatures in the world? It is still unknown at this time, but the late British physicist Stephen Hawking once publicly stated before his death that the existence of alien creatures is likely to be real!
As an atheist, anti-war activist, and anti- capitalist , Hawking's remarks have always given people a very rigorous impression, but he has stated in public many times that alien life exists completely, which has a huge difference from the familiar Hawking personality. Why should Hawking say so?
Hawking believes that it is unrealistic for us humans to be the only intelligent creatures that exist in this vast space. In the space of the universe, alien creatures know our existence, but they do not care about our existence.
He immediately advocated the search for alien life and warned of the potential dangers of first contact with alien species, Hawking's position on life outside the earth advocated two methods: collecting intelligence and keeping as quiet as possible.
Hawking said in announcing support for the Breakthrough Listening program that it is a $100 million program designed to find communications from aliens through radio waves and visible light observations of nearby 1 million stars and 100 Galaxy centers. According to his words, "It's time to work hard to find answers and find life outside the earth!"
In 2010, Hawking still maintained this view in an interview. He described the danger of first contact with aliens in the Discovery Channel documentary. He said: "If aliens visit us, the result will be the same as when Columbus landed in the Americas. The result is not good for Native Americans. We just need to see how intelligent life will develop into something we don't want to see."
Hawking believes that based on the absolute number of planets that scientists know must exist, we are not the only form of life in the universe. After all, there are billions of stars in our Milky Way alone, and it is reasonable to expect that even more planets orbiting them, and it is not unreasonable to expect some alien life to be intelligent and be able to communicate interstellarly!
In fact, in addition to Hawking, some scientists also recognize this theory. Seth Shostark, a senior astronomer from the Seti Institute in California, also said that we know very little about aliens. From the perspective of alien life, the contact between humans and low-intelligence creatures is often disastrous, and the encounter between civilizations with advanced technology and primitive technology is a bad thing for less advanced civilizations.
Just imagine, these alien life civilizations that read one of our messages may be billions of years ahead of us. If so, these species will be stronger and may no longer regard us as advanced species in the universe!
Throughout history, human searches for aliens have never been interrupted. In 1960, when Frank Drake pointed the Green Shore Radio Telescope of West Virginia to Uranus . He was looking for abnormal radio signals that might be emitted by intelligent life. However, until now, the sky is still silent.
Because there are many practical problems in finding aliens, the most important one is the distance. After all, the distance between Venus, the closest to our earth, reaches 41.5 million kilometers. According to the current scientific ability, it takes about 100 days to reach Venus. This will have a certain delay for us to collect signals on this planet, so the accuracy will decrease. However, the lack of signals from aliens does not stop astronomers and biologists, including Hawking.
However, while Hawking is almost certain that there are alien life in the universe, he does not believe that aliens have visited the Earth through UFOs or at any time in history, "Why is the Earth not visited, or even colonized?" Hawking wrote on his official website.
