article | Interesting popular science knowledge
Astronomer Amir Siraj and professor of natural sciences Abraham Loeb released a research result on "Journal of Astrophysics" :
2014 The meteor that broke into the Earth's atmosphere in 2014 CNEOS2014-01-08, it has been confirmed that it is from another star system , and it is the first known interstellar visitor, 3 years earlier than Oumuamu.
"Interstellar Visitors" frequently appear. Scientists believe that this has inspired the exploration of the source of life seeds on Earth - Although there are low temperatures and rays in the universe that are unfavorable to life, there are still conditions that can nurture life inside small celestial bodies, and may become the ark for spreading life between the stars.
Therefore, some scientists believe that there are other life outside the solar system, which creates new questions: will the alien civilization use such objects to shuttle and explore in the universe? How should humans deal with it? Is it time to answer?
This reminds people of Stephen Hawking left 6 terrible prophecies for humans, 3 of which are being staged quickly. Among them, the prophecies about aliens echo the above questions. He warned humans not to provoke aliens easily. Why is this?
Hawking 's life and 6 terrible predictions
Hawking suffered from ALS at the age of 21. He was paralyzed and could only communicate with people with a few moveable hands. He survived the 25-year-old term that the doctor asserted, and became the most influential physicist after Einstein . He gave birth to three children with his wife until he died on March 14, 2018 at the age of 6.
Hawking's spirit of fighting tenaciously with the disease is admirable. His attainments and achievements in exploring the universe are almost unparalleled today, and his predictions about the future of the world are even more amazing.
- The first prediction: humans may eventually be destroyed by artificial intelligence
Although Hawking was restricted to a wheelchair due to physical problems, his thoughts have been moving forward. He needs to rely on artificial intelligence to convert the ideas in his mind into language to express them, but he does not agree with the unlimited development of artificial intelligence.
According to Hawking's view, in the next hundred years, artificial intelligence will be filled with human life and replace human work, and can solve work, diseases and even social problems for human beings. In other words, human roles will gradually be replaced by artificial intelligence.
If it develops unlimitedly, artificial intelligence will sooner or later develop self-awareness . Most people's brain development level is almost no competitiveness compared to computers.
At that time, humans may be subject to artificial intelligence , and their lives and safety is threatened.
- The second prophecy: "Aliens" may really exist
Popular Science Documentary "Understand the Universe with Hawking" , Hawking puts forward the conclusion that "Aliens" may exist.
He believes that there are hundreds of billions of galaxies in the universe, and the number of stars cannot be calculated. It is impossible that only the earth has life. He warned humans not to to provoke aliens, do not say hello, and do not answer any signals !
- The third prediction: human beings will eventually face an existential crisis on the earth
As the problems of greenhouse effect , environmental pollution and other problems become more and more serious, coupled with the global situation and the potential nuclear war problems, Hawking believes that human beings are currently facing a severe survival crisis and may not live after 3,000 AD.
- The fourth prediction: the earth will eventually be burned and become a fireball
Hawking believes that as the population of continues to expand, human beings' demands and plunders of nature become more severe, and the earth's energy will eventually be exhausted, and finally become a burning fireball;
If you want to solve this problem, the best way for is to immigrate to another planet , the faster the better.
- The fifth prediction: genetically modified technology will bring a fatal threat to people
Hawking believes that in addition to nuclear weapon , biotechnology research will bring huge challenges to human survival, such as genetically modified technology and various unknown viruses , etc. humans will one day die from some unknown virus that they have developed, and it does not have related drugs that can be treated.
As of now, humans seem to be facing such a problem.
- The sixth prophecy of human beings will eventually realize
Hawking believes that there are "black holes" in the vast universe that can connect two different time and space. If humans can discover it, they can use it to shuttle back and forth between different time and space.
However, Hawking does not agree to travel back to the past, because history changes, the future will change accordingly, which will disrupt the order of time and space.
Among the six terrifying prophecies, three are rapidly being staged: Artificial intelligence, genetically modified technology and the survival crisis faced by humans , which has also made many people face Hawking's prediction again.
As humans gradually explore the universe , Hawking's prophecy about aliens has also attracted much attention. So, why did he warn humans not to provoke aliens easily?
Why did Hawking warn humans not to mess with aliens?
What Hawking said about not messing with aliens means Don’t expose your position .
He believes that the alien life form of cannot be determined , but what can be confirmed is that the biological levels of the universe are uneven .
Some planetary life may still be in its original state, but some have evolved into advanced civilizations. In the cosmic civilization level designated by humans, humans are at level 0.8 , which is equivalent to being at the bottom of the food chain !
Hawking said that high-civilized aliens with a level above 3 may have discovered the existence of human beings and have even mastered the civilization of the earth. It is not that they have no way to come to the earth, but they are disdainful of it.
Human science and civilization have neither value nor threat to high-level aliens, so there is no need to come to the earth specifically.
However, if humans continue to send signals to other planets to expose their location , they may be regarded as a provocative behavior , or invitations, then these high-level civilizations may come to the earth to "teach a lesson".
Hawking compared the consequences of alien visits to the earth with Columbus set foot on the American continent , and the result will only be more serious.
So, when receiving unknown alien signals, do not answer easily, because this will also expose the location and may cause danger.
Each future of the earth predicted by Hawking is related to the survival of mankind, terrifying and terrifying, and the possibility of future happening is also very high.
As the population continues to increase, environmental deterioration, war and other problems become more and more prominent, we don’t know how many years the earth can support human survival, and plans to immigrate to other planets are still being explored.
What we can do is to try our best to maintain the home on which we rely on, actively save energy and reduce emissions, plant trees and afforestation, and continue to work hard for the sustainable development of the earth.
