One thing that all unconventional sailing methods have in common is that they are expensive, time-consuming, and extremely low in terms of profit. Just like the hibernation voyage adopted by Wei Feng in the Island Plan, just sending a person to the South Gate Two Galaxy costs 1.5% of the total annual human civilization economy. What about the benefits? The silo plan can be said to have no substantial benefits.

If Wei Feng is not wrong, Führer Keller should have seen this paradox at the beginning, and the promotion of the island plan may just be a foreshadowing for Führer Keller's subsequent larger-scale unconventional voyages out of the solar system.

If this is successful, the subsequent heads of state may push for the same unconventional way of sailing, sending a group of scientists and a group of observations out of the solar system to gain more knowledge.

But there is a problem with this scheme. Not only is it time-consuming, it is costly, but for a given period of time - note that this may be three or four thousand years - this program will not bring any tangible return to human civilization. Its benefits may not be felt until three or four thousand years later.

Because unconventional navigation is so inefficient, it is extremely difficult to acquire knowledge in this way. The amount of resources it would take to send enough scientists and instruments out of the solar system could be astronomical, and it could well push down the average standard of living of people within human civilization. And within three or four thousand years, these consumed resources cannot bring back any visible return for human civilization, then this forms a dead knot.

Because the populace is always short-sighted, no. And not only the populace. Even if it's a wise man. He probably won't be able to look long enough to see the benefits three or four thousand years from now. Attempts to break the knot by unconventional sailing, then, are bound to meet with tremendous resistance.

Wei Feng thought of a way to break the dead knot, but Wei Feng immediately rejected this method. It's too difficult for anyone to accept. It's like saying to people hundreds of years ago who were still in the age of the state that they should starve for 500 years, 10 generations in exchange for the prosperity of the country in 500 years, and those who put forward this argument must be considered insane.

Führer Keller may have been such a madman. He looked far enough to see three or four thousand years from now, and three or four thousand years ago today he began to pave the way for breaking the paradox. Perhaps it is precisely because of this that there is a lonely island plan, and there is Wei Feng who is drifting in the endless starry sky at the moment.

At this time, Wei Feng suddenly thought that Keller's death might be because of this incident. The island plan consumed 1.5 percent of the total annual wealth of mankind that year, and I don't know how many people did damage to the interests of many people, so ...... Is it for this reason that Führer Keller was murdered by a conspiracy?

Wei Feng felt that his heart was a little cold. If Führer Keller really died for this reason, then the many Führers who took office next ...... Do they still have the courage to be such madmen? After all, the Führer will always leave office, and he will always hand over power. Just because you're safe in office doesn't mean you'll be safe when you leave office.

Even if the Führer is for life. The Führers must also take into account the possibility of popular uprisings and violent overthrow of the rule.

If none of the only way to break the paradox is viable...... Where should human civilization go? Technological development has come to a standstill, and it has been trapped in the solar system, and then ...... Just disappearing into the universe without a sound?

Chu Hai's letter was not finished yet, Wei Feng pondered for a while, and then continued to read it.

"We're dealing with a dead knot. Wei Feng, I thought of a question that has puzzled people from hundreds of years ago to today, that is, where are the aliens? Now I think that the thing may be like this, there may indeed be many civilizations in this universe, but all of these civilizations are locked by this paradox that plagues our human civilization today, and they have not found a way to break the paradox until the extinction of civilization, and they have not been able to get out of their own galaxy until extinction, and naturally they cannot be found by our human civilization. ”

Wei Feng knows the question "where the aliens are", and this question is known as the Fermi paradox. The Fermi paradox is that according to the model, there should be many civilizations in this universe. The age of the universe is more than 13 billion years, and the age of the solar system is only 5 billion years. So, according to the model that the longer it exists, the more advanced science and technology become, there should be many civilizations in this universe that are very technologically advanced, but why has human civilization not noticed any signs of the existence of extraterrestrial civilizations until now?

Chu Hai said that he believes the answer to Fermi's paradox is that although there are many Chinese in this universe, no civilization can break the dead knot between "sailing speed" and "acquiring more knowledge", so they all perished.

"I think that our human civilization will eventually follow in this footsteps. Because we also don't have a way to open the dead knot. And if you can't tie the dead knot, you can only extinct it. ”

Now, Wei Feng naturally knows about the existence of alien civilizations. Because if extraterrestrial civilizations don't exist, then the high-tech metal fragments in that irregular asteroid can't be explained. However, after learning about the knot between "sailing speed" and "gaining more knowledge", Wei Feng has more ideas about the alien civilization that has arrived in the solar system.

Since that extraterrestrial civilization can come to the solar system and fight a large-scale war in the solar system - although Wei Feng is not sure of the reality of the large-scale war at this time, because Wei Feng has not yet obtained more conclusive evidence, Wei Feng thinks that this inference is very probable, because the probability of such a thing as "accidentally found a piece of debris on an asteroid" is too low, and it is too far-fetched to explain it by coincidence, then it must prove that the extraterrestrial civilization has the ability to travel to the stars. And if this "dead knot" is a common problem faced by many civilizations in the universe, then this alien civilization has undoubtedly broken this dead knot.

Because it is obvious that only by breaking the knot can we gain the ability to travel to the stars. In the same way, since they have broken the dead knot, their technological level should be much higher than that of human civilization.

But...... Why wasn't that piece of metal as high-tech as expected? Wei Feng clearly remembers the performance parameters of the fragment material, these parameters show that although its scientific and technological content is higher than the scientific and technological level of human civilization, it is limited higher, according to the current scientific and technological development rate of human civilization, it is at most less than a hundred years higher - of course, this is according to the current scientific and technological development speed of human civilization, Wei Feng has no way to determine whether the scientific and technological development of human civilization will slow down or even stagnate in the next hundred years.

But at least so far, Weifeng has found no signs of stagnation in the scientific and technological development of human civilization.

What does this mean? Does this mean that the technological development of human civilization will be able to break the dead knot and obtain the ability of interstellar navigation in another hundred years? Or does this dead knot not not exist at all? Or, is it only human civilization that is facing a dead knot, and extraterrestrial civilizations are not bothered by this dead knot?

Wei Feng couldn't be sure which of these three speculations was correct. It will take time to get the answer to this question.

Chu Hai's letter continued, "Wei Feng, I already have some bad premonitions in my heart about the fate of our human civilization. I don't know what we will face in the future, our individual power is too small to exert influence on the entire human civilization, which is really a torture for us who have a long life. The only thing we can hope for is...... Hopefully, in a thousand years, we will be able to meet again. ”

This was the end of Chu Hai's letter, and Wei Feng fell into a long thought. But this thinking was destined to be fruitless, and after thinking about it, Wei Feng was even more at a loss.

With a long sigh, Wei Feng gave up thinking and began to conduct recovery training under Ye Luo's arrangement.

Life is back to that state of calm again. The universe is always dark and empty, and life is always lonely and lonely. After a period of recovery training, Wei Feng regained some strength, so he repaired all the faults in the spaceship, and then eliminated some bugs accumulated during the operation of the leaves, and the time came two months later.

"It's time for you to hibernate." Ye Luo said.

Wei Feng lay down in the hibernation pod again. Before entering here, Wei Feng had instructed Ye Luo to search for possible fragments of unknown civilization creations near the route, and granted Ye Luo the power to urgently awaken himself under certain circumstances.

"Leaf fall, goodbye." Wei Feng said this with a smile, and the hatch of the hibernation pod began to slowly close.

Before losing consciousness, Wei Feng turned this thought in his mind: "My report on the discovery of fragments of unknown civilization is estimated to have been transmitted to the solar system at this moment, I wonder what kind of attitude our government will have towards this report?" This should be the first time that our human civilization has found evidence of the exact existence of an extraterrestrial civilization......"

Consciousness slipped away quietly, and Wei Feng once again fell into a deep sleep. Once again, the spaceship turned off all non-essential equipment on the spacecraft, and continued to turn into cold stones in the universe, continuing its lonely journey that would last for thousands of years. (To be continued......)
