Hundreds of years ago, after continuous development, human civilization finally entered the road of science and technology. With the help of technology, we quickly walked out of the earth and began to explore the universe. Among the many mysteries of the universe, the question of whether an alien civilization exists has always been a hot topic of discussion.
In order to find extraterrestrial civilization, scientists started the extraterrestrial civilization search program more than half a century ago. We use various methods to search for traces of possible alien civilizations in the universe, but until now, we have not found any alien civilizations.
Does not discovering extraterrestrial civilization mean that they do not exist? Of course not. In fact, with the continuous advancement of human science and technology and the continuous improvement of cognition of the universe, the probability of the existence of alien civilizations is getting higher and higher. Now more than 90% of people believe in the existence of alien civilizations. Astronomers are basically positive about the existence of alien civilizations.
Because the more you know about the universe and the more you know, you will know that the probability of existence of alien civilization is basically 100%. Even the existence of human beings means that there will be other intelligent civilizations in the universe. If alien civilizations do not exist, it means that humans should not exist either. And since human beings exist, other intelligent civilizations should also exist.
Although we have not discovered any alien civilizations until now, some scientists say that within the next hundred years, humans have the hope of truly discovering alien civilizations. The high probability of this discovery will be that alien civilizations come to the solar system and come to the earth. If this is the case, we will have to consider another possible result, that is, alien civilizations invade the earth.
I believe that many friends have seen a lot of science fiction works, and these science fiction works often have plots of alien civilization invading the earth. In these incidents, the preliminary alien civilization was very powerful, and humanity was regressing steadily, but in the end, human beings found the weakness of the alien civilization and eliminated it.
In the movies where alien civilizations invade the earth, they all end with the victory of mankind. But if such a plot happens in the real world, can human beings still win? A friend once asked such a question: If an alien civilization invades the earth in the next 100 years, what is the chance of mankind’s victory?
Once the interstellar war between mankind and alien civilization breaks out, although the solar system and the earth are the home ground of mankind, the key to our victory in the end depends on how strong the technological strength is. If there is not much difference in technological strength between the two, then the human beings as the home court are naturally very likely to win.
But if the civilization strengths of the two are too different and are not on the same level at all, then the possibility of humans winning is very slim. If there is an alien civilization invading the earth now, then the probability of human victory is basically zero. It is necessary to know that an alien civilization can cross the interstellar to the earth, even if it comes from the nearest galaxy to the earth, the technology of this civilization The strength has reached the first level at least, mastered the basic sub-light speed flight technology, and at least mastered controllable nuclear fusion.
Because to cross the interstellar space, the speed of the spacecraft is not sub-light speed. At the speed of our current spacecraft, it is impossible to reach the Biling galaxy from the solar system within hundreds of thousands of years. It is impossible for any civilization to spend hundreds of thousands of years to invade other galaxies. Only when the speed reaches the primary sub-light speed can it have the primary galaxy navigation capabilities.
With the current technology of mankind, is there a chance of victory for an alien civilization that has mastered interstellar navigation and controlled nuclear fusion? The answer is no, because our weapons can hardly pose any threat to alien civilization spacecraft, and alien civilization has at least mastered basic energy weapons by relying on nuclear fusion technology. This kind of power gap is equivalent to the comparison of modern humans with the human powers thousands of years ago. Just imagine how powerful the ancients can beat the modern technological power? The answer is very obvious.
Therefore, if an alien civilization invades the earth in the future, whether mankind can win or not depends on how far our technology will develop at that time. So how strong will human civilization be in a hundred years? Let’s take the core energy technology as an example. Energy is the foundation of the development of civilization. If energy cannot achieve major breakthroughs, the level of the entire human civilization cannot be improved.
The energy that can enable human civilization to achieve a leap is controllable nuclear fusion. The energy we use now is fossil energy, and its development has basically reached its limit. The power of nuclear fusion is believed to be well understood by everyone. Once it is realized, human beings may be upgraded from level 0.7 to a first-level civilization, that is, a primary interstellar civilization. At that time, we will be able to master the primary subluminal flight technology and have the ability. Initially out of the solar system, to explore nearby interstellar.
Only by becoming an elementary interstellar civilization and facing possible alien civilization invasion in the future can it have a certain elementary combat effectiveness. If we cannot become a primary interstellar civilization in the next hundred years, then we do not even have the most basic ability to fight interstellar wars, and facing the invasion of an interstellar civilization, we basically have no chance of winning.
Many people may have watched some sci-fi movies in which alien civilizations invaded the earth, and the plots all ended with the victory of mankind. But in the real world, this kind of thing will basically not happen, unless there is a problem inside the alien civilization, and the possibility of this is basically zero.
Some friends may have said that the bacteria and viruses of the earth can wipe out alien civilizations, because such plots have appeared in some science fiction movies. So does this happen in the real world? The answer is no, because for a powerful and powerful interstellar civilization, when they come to the earth, they can easily figure out the various natural composition of the earth.
After an alien civilization understands the bacteria and viruses of the earth, it can easily produce relevant medicines to immune the earth virus, so it is impossible to eliminate the alien civilization by relying on bacteria and viruses. So in the end, the only thing that really fights is whose weapon is stronger. Before mankind has controllable nuclear fusion, the most powerful weapon that can be obtained can only be nuclear weapons.
But if our nuclear weapons want to hit the spacecraft of the alien civilization, it needs the boost of the rocket, but can such a backward attack method attack the spacecraft of the alien civilization? The answer is no, because in the face of energy weapons, our rocket speed is the turtle speed, according to which we can’t get close.
So is human controllable nuclear fusion technology expected to be realized within a hundred years? This possibility is unlikely. As early as 50 years ago, scientists made a bold statement: human beings will be able to master controllable nuclear fusion in 50 years. But now 50 years have passed, and we still have not made breakthrough progress on the road of controlled nuclear fusion research.
Now scientists no longer dare to make rhetoric that mankind has the hope of mastering controllable nuclear fusion in 50 years. This shows that the difficulty of realizing this technology is very high, and some scientists even believe that controllable nuclear fusion is far from being researched and explored by existing human science and technology. It takes luck to achieve controllable nuclear fusion within a hundred years.
But if there is no controllable nuclear fusion, many technological developments of mankind will not be able to truly break through, especially in space exploration. And without the support of nuclear fusion, we have no chance of winning against any interstellar civilization.
For this reason, Hawking has issued warnings on many occasions, telling humans not to easily launch human civilization signals into the universe, because such signals may be received by powerful alien civilizations. Once the human signal is received by the alien civilization, the exposure of the earth and humans is also a high probability event.
At that time, alien civilizations may send a fleet to the solar system, and the universe may have the law of dark forests. If the earth is discovered by alien civilizations, it is possible that the end of civilization is the end of civilization. Therefore, before human beings are truly powerful, we should hide ourselves instead of actively exposing ourselves.
