Earth Era

These hydrogen bombs used for space-blocking programs are not the same as traditional hydrogen bombs. They are not cylindrical, and then have a pointed bomb shape. In fact, because they are too big and the internal machinery is too For the sake of precision, they had to be made very large—the size of a spaceship. So scientists simply made this hydrogen bomb directly into the shape of a spacecraft, and equipped them with a power system and a navigation system. When the mission begins, they will fly to the predetermined location by themselves under the control of the staff.

Zhao Lan saw such a hydrogen bomb in the shape of a spaceship in the factory building. The factory building is located at the other end of the space elevator, inside the earth port. This hydrogen bomb was assembled in the earth port, because it is too large, it is impossible to launch it from the earth. It is about the size of Zhao Lan's car, the Sylvia spacecraft, but its mass is more than ten times that of the Sylvia spacecraft. Because many places inside the Sylvia spacecraft are empty and used as living spaces and the like, this "Hydrogen Bomb One" spacecraft is mostly solid, filled with nuclear fusion fuel and various Various sophisticated control machinery.

Zhao Lan led the scientists of the mission team to inspect the H-Bomb-1 spacecraft in detail. After a few hours of inspection, he finally signed his name on the inspection record. After that, the hydrogen bomb No. 1 spacecraft was launched, and it flew out directly from the earth port and walked slowly towards the deep space. At this time, Zhao Lan and his party left Earth Harbor and returned to the ground experimental observation base.

Yes, the H-Bomb 1 spacecraft will not be used for space interdiction. In fact, it is just a test hydrogen bomb that will explode in an open space in space. The energy released by its explosion is then observed to determine whether the hydrogen bomb level is sufficient. This is important, after all, hydrogen bombs with such huge yields only exist in computational models. In the history of human civilization, people have never really made such a huge guy.

So on the third day after the H-Bomb One spacecraft was delivered. People in the Eastern Hemisphere suddenly discovered that the sky was bright at about ten o'clock in the evening. A ray of light that was far stronger than sunlight was released from the eastern sky, instantly dispelling the darkness of the entire land, and allowing light to come to the world ahead of schedule. But this burst of light did not last for too long, it only lasted for three seconds and then disappeared quietly, and then the sky quickly returned to darkness, the stars were still stars, the moon was still the moon, and nothing changed. This sudden and peculiar change made people wonder if the light they had seen before was an illusion.

Zhao Lan didn't care how the human society would react to this sudden light. I don't care what reason the public opinion department will use to explain this matter. Zhao Lan only knows that the latest hydrogen bomb has passed the test perfectly, and the data observed by the instrument tells Zhao Lan that this hydrogen bomb is fully capable of blocking space. , the task of preventing the earth from falling into the empty universe - of course, with the cooperation of that black hole.

Time is still passing quietly, and it is getting closer and closer to the time node in the calculation - so far, there are only less than four months left. At this time, Zhao Lan went to the base again. Then Zhao Lan discovered that within a few dozen kilometers around the base, the appearance had completely changed. The flying car was flying over the snow-capped peaks a while ago, the next moment. I came to a place where birds and flowers are fragrant, and the green rush is like a paradise.

The large-scale construction some time ago completely killed all the vegetation that survived on the surface, but the plant seeds hidden in the dirt and rocks were not killed. With the heat support provided by the large-scale cooling equipment, those seeds mistakenly thought that the warmth had returned to the earth, so they began to take root and sprout, and finally broke out.

The temperature here is high, the rainfall is frequent, and the vegetation is lush. So the animals that would have hibernated did not fall asleep but came to this place and began to multiply here.

The flying car landed on a clearing. Zhao Lan heard the sound of birds chirping around, as well as the faint roar of wild beasts. Underfoot is wet soil. There are lush green grass around, and a flowing stream not far away... Everything is as beautiful as a picture.

Zhao Lan knew. The nutrients that support all these beautiful existences in this cold winter are all stolen from the body of the black hole. A black hole can destroy everything, but if used properly, it can also nurture everything.

Black holes play the most important role in the evolution of galaxies. It is its massive gravitational pull that allows stars and stardust to converge and galaxies form. There is nothing without black holes. Even the extremely tiny black hole that exists in the base now... Its extremely huge radiation energy may also be used as the driving force to drive the spacecraft forward in the future.

The scientists in the base have even done related research. Their final conclusion is that it is entirely possible to use a black hole as the power source of the spacecraft, because the radiation of the black hole is continuous and gradually strengthened, while the mass of the black hole is gradually reduced, and the reduction of the mass of the black hole means the overall mass of the spacecraft. The effect of a certain amount of energy will be greater and greater. If a black hole is really used as a spacecraft engine in the future, its acceleration mode is probably like this:

In the initial stage, the mass of the black hole is very large, and the radiation is relatively slow. At the same time, because the black hole is installed on the spacecraft, the total mass of the spacecraft must also be large. Then the relatively slow radiation may only have a little effect, so the spacecraft can only move forward at a very slow acceleration.

But with the passage of time, the total mass of the black hole and the spacecraft gradually decreases, and the radiation rate continues to increase, so the acceleration obtained by the spacecraft becomes larger and larger.

The most important point is that the acceleration provided by the black hole is continuous. The lifespan of a black hole with a mass of one million tons is about thirteen years, that is to say, the black hole can continuously provide up to ten years. Three years of energy supply and acceleration.

The most obvious benefit of carrying a million-ton black hole compared to simply carrying a million tons of fusion fuel is space savings. Obviously, the volume of a black hole is countless times smaller than the volume of one million tons of fusion fuel, which means that the spacecraft does not need to be built too much, or the spacecraft can save more space for other purposes. use.

In addition, compared with conventional fusion engines, black hole engines have the advantages of safety and simple equipment manufacturing, and the most important point is that the fuel is easy to obtain.

Fusion fuel is not easy to obtain in the empty universe. If they want to replenish fusion fuel in the universe, spacecraft controllers must venture close to gas giants, or venture on rocky planet grounds to find water sources to decompose to obtain hydrogen, or risk catching comets for fuel. A black hole is different. Whether it is encountering asteroids or comets, or even radioactive garbage, stardust, etc., as long as it is matter, it can be thrown into a black hole to continue its life and serve as fuel. In the most extreme cases, people can even Dismantling the ship's unnecessary hull and throwing it into the black hole to act as fuel. Compared with fusion fuel, the advantages of black hole engines can be seen at a glance.

Scientists at the base even believe that the black hole engine will be the only option for interstellar travel. If one day human civilization hopes to step out of the solar system, explore Proxima Centauri or Tianyuan 4, Sirius and other outer stars within a few decades and return to the solar system smoothly, the black hole engine may help people achieve this desire.

But the most important point is... the production of black holes is too difficult, and the existing technology of human civilization is not enough to create black holes. The only remaining black hole is that Li Yunfan didn't know where he got it. He wants to create a black hole on a large scale to act as a source of energy... I don't know when the technology of human civilization can reach this level.

Hearing the murmur of the stream and the chirping of birds, Zhao Lan's thoughts drifted a little far. It wasn't until the communication equipment around him started to sound that Zhao Lan came back to his senses.

"What's wrong?" Zhao Lan asked.

Li Yunfan's voice came from the communication device: "Zhao Lan, this will be the last call between us. After this call, until I return to our universe, we will no longer be able to communicate."

Although he already knew the result~www.readwn.com~, when this moment finally arrived, Zhao Lan was still a little disappointed. Zhao Lan said, "Oh... well."

In the previous time, Zhao Lan had communicated too much with Li Yunfan. Every detail of the plan had been confirmed again and again, and all questions had been discussed in detail. Therefore, at the last moment, Zhao Lan did not know what to say. what.

"Don't you have anything to say to me?" Li Yunfan said with a smile, "After all, this may be the last call in our lives."

Zhao Lan was silent for a while, the words "I'm waiting for you on Earth" kept surging, but he couldn't say it. So Zhao Lan remained silent, and Li Yunfan smiled again and said, "Is there really nothing to say? Then... 呲呲... ok... 呲呲..."

Before Li Yunfan's words were finished, the communication was disconnected. Zhao Lan felt a little relaxed and regretful, not knowing what it was like.

"From now on, everything depends on us." Zhao Lan turned around and shrugged at An Liya and her group, "Your boss has completely lost contact with us." (To be continued)
