Soon after human beings walked out of the earth, they launched the extraterrestrial civilization search program. Although we have made a lot of efforts in more than half a century, we still have no discoveries. However, as time goes by, scientists are searching for extraterrestrial civilizations. Not only did the enthusiasm not decrease, but it got higher and higher. Why?
Some people may say that the reason why human beings are so enthusiastic about finding alien civilizations is mainly out of curiosity, wanting to find out whether there are other intelligent civilizations in the universe, and what is the form of alien civilizations? What does the alien look like?
So is the enthusiasm of scientists looking for alien civilizations so high, really just because of curiosity? It may not be that simple. Although scientists have not found traces of alien civilizations after more than half a century of hard work, scientists have no doubt about the existence of alien civilizations.
The space of the universe is too large for us to imagine. With the current technological strength of human beings, the observable range has reached 93 billion light-years. And this range is only the tip of the iceberg of the universe. Some scientists believe that the current radius of the universe may have reached 12 trillion light-years, and this number is still increasing with the rapid expansion of the universe.
Even within the range of 93 billion light-years, there are at least trillions of galaxies like the Milky Way, and every galaxy like the Milky Way will have hundreds of billions of star systems, and each star system has a different number. Planets, which naturally also includes terrestrial planets in the habitable zone.
With such a vast cosmic scale and 13.8 billion cosmic history, the probability of the existence of alien civilizations is basically 100%. Therefore, scientists are actively searching for alien civilizations, not trying to prove the existence of aliens. Because this does not need to be proved, it is like human beings have been searching for dark matter and dark energy, not trying to prove their existence, and their existence need not be doubted.
Scientists look for dark matter and dark energy, just to figure out what their essence is? What benefits can it bring to human civilization. Scientists are actively exploring and searching for alien civilizations, naturally, not because they are curious about them and want to prove anything, but only for the future of human civilization.
Don’t scientists know that contact with alien civilizations may bring huge risks to mankind? They certainly know that Hawking has repeatedly warned humans not to try to contact alien civilizations, which may bring unknown risks. Although we know everything, we have never given up on the search for alien civilizations, and our enthusiasm is getting higher and higher. Now our celestial eyes have also joined the search for alien civilizations.
Such an active and enthusiastic search for alien civilizations shows that human beings must have expectations for alien civilizations. So what do we expect? Naturally, I am looking forward to receiving the friendship and help from the alien civilization, and looking forward to getting some advanced technology from the alien civilization, so that human civilization can become a powerful interstellar civilization as soon as possible.
Some people may not understand: Is it not good for human beings to work hard to develop technology? Why seek help from an alien civilization? In the eyes of many people, the formation of human civilization is only about 5,000 years old, and the development of science and technology only has a few hundred years. In such a short period of time, mankind has stepped out of the earth and began to understand the universe initially. Then, at the current development speed of mankind, as long as we are given enough time, it is possible to become a powerful interstellar civilization.
The fact is true. The speed of human science and technology development is indeed very fast. As long as there is enough time, such as 10,000 years, 100,000 years, or even millions of years, hundreds of millions of years, then sooner or later human beings will become a powerful interstellar civilization and realize it. Interstellar travel. But will the development of human science and technology be smooth sailing? Can it continue to develop safely and steadily until it becomes an interstellar civilization?
Many people may think that human development will be smooth sailing, but scientists do not think so. As scientists at the top of human science and technology, they see and perceive far more things than ordinary people. Scientists can see risks that we can’t see.
In fact, the future development of mankind is unlikely to be smooth sailing, and there will be many challenges on this road of science and technology. These challenges include the risks of the earth’s own system, the risks within human beings, and the disasters from the universe beyond the earth.
The earth’s ecosystem has not been truly stable for billions of years, and there will be ecological drastic changes every once in a while, triggering mass extinction events. In nearly 500 million years, the earth has experienced five major extinction events. However, 66 million years have passed since the fifth mass extinction. According to the time period, the sixth mass extinction may not be far away. Some scientists even believe that the earth may now have entered the early stages of the sixth mass extinction.
Human beings are not peaceful and stable. There have been two world wars in modern times. Will there be a third and fourth world war in the future? Einstein had a prediction: “I don’t know what weapons mankind will use in World War III, but I know that in World War IV, mankind will use stone tools and wooden sticks.”
The danger on the outside of the earth is even greater. In 1994, a huge comet flew towards the inner galaxy. If it weren’t blocked by Jupiter in front, it might hit the earth directly. If so, it’s impossible now, my friends. Sit here to read this article. The impact of this comet is powerful enough to turn the earth into a second Mars.
In summary, the human ecological environment is not particularly safe. Before we became an interstellar civilization, whether it was the mass extinction catastrophe of the earth or the catastrophe from the universe, we had no way to deal with it. The result of probability is the end of human civilization and become a passerby on the earth.
For human beings to become an interstellar civilization, they must at least become a second-class civilization. Only the second-class civilization has the ability to initially sail across the stars before it can reach other galaxies outside the solar system. And the current civilization level of mankind is only 0.7, not even the first-level civilization. According to conservative estimates of scientists, it will take at least hundreds of years for human beings to grow into a first-class civilization, while it takes tens of thousands of years to become a second-class civilization, and hundreds of thousands of years.
Can human beings wait for such a long time? Obviously, we can’t wait. Unknown disasters will come at any time. To shorten the time of technological development and make human beings quickly become an interstellar civilization, we can rely on advanced civilizations in the universe.
According to the 13.8 billion history of the universe, it is understandable that there are advanced civilizations that are tens of thousands of years more advanced than human beings, hundreds of thousands of years or even hundreds of millions of years. If we can get in touch with such a powerful civilization and get help and technological support, then it will be very easy for human beings to become an interstellar civilization. It would have taken tens of thousands of years, but now it may only take a few months or less.
It can be seen that although human contact with alien civilization has certain risks, it may also be a huge opportunity. The time for human beings due to the development of science and technology is still very short. Coupled with the various natural disasters and cosmic disasters that may be faced in the future, what we lack most now is also time. Only by contacting and communicating with powerful alien civilizations can this time be greatly shortened and the civilization level of mankind can be rapidly improved.
