Chapter 157: Prepare for Both Situations

The Green Light Civilization could never have imagined that the "amazing" new human civilization, which seemed to have a higher level of technology than them, could not leave the solar system!

Humanity is struggling frantically for the survival of the entire civilization.

In the following meeting, people established two basic survival routes:

The first is to bomb the Green Light Civilization's spacecraft with nuclear bombs to prevent them from detonating the sun! As for the problem of the unknown fleet behind, we can only take one step at a time and consider it later.

The second is that if the bombing plan fails, humans will resort to the second best and struggle through the Noah spacecraft to see if they can survive the supernova...

In short, humans need to prepare for both of these routes. People can't think of any other ways for the time being...

Issues related to nuclear bombs have been taken over by Ding Yidong and others, and now people are mainly considering the situation after the bombing plan fails.

That is the situation they least want to face - supernova!

"I think we should start building the radiation wall now, instead of waiting for the results of the bombing plan, because it will be too late!"

"...The thicker the better, one thousand meters or even ten thousand meters!"

A scientist stood up and said loudly, he was in an extremely excited state.

"Moreover, our spacecraft can't float in the air. We need to collect Martian resources as much as possible and build a thicker radiation wall!"

Yu Yifeng also nodded. If the spacecraft floats, it will be a waste of time and life. If the Noah resists the supernova intact, but humans die because of gamma ray radiation, it will be a joke.

"Yes, we must prepare as soon as possible!"

The speaker was Dr. Roman, and his expression was also very serious. "I will talk about the issue of radiation protection materials now. As everyone knows, the Martian virus has a very good radiation-resistant capsid, which is an organic metal with a radiation protection ability 13 times that of ordinary lead plates!"

"In biological laboratories, the research on this new material has made good progress. Perhaps it can be used to build radiation-proof walls..."

"And when this metal melts, it can absorb a lot of heat."

Yu Yifeng's heart moved. This is good news!

Gamma rays have very strong penetrating power. When a gamma ray with an energy of 1MeV passes a distance of 100 meters in the air, its intensity is only reduced by half. And it can penetrate lead plates several centimeters thick.

Generally speaking, the larger the atomic weight of the metal, the better the radiation protection effect. However, due to the price of metals, lead plates are often used in laboratories.

But the gamma rays from star explosions can reach a maximum energy of 100TeV! Such an energy level is completely brute force. It can directly heat the metal plate to gasification or liquefaction, and it does not care about lead plates or uranium plates at all. It can directly destroy them violently...

On the one hand, humans have to hide behind Mars and use the entire planet for shielding.

On the other hand, they have to strengthen the construction of radiation-proof walls. They must build countless radiation-proof walls in a crazy, rough and barbaric way!

"We only need to use walls to block the living area and industrial area. Other places can only be abandoned." This is the voice of a construction engineer.

Because of the expansion space inside the spacecraft, the surface area inside Noah is extremely large and it is impossible to surround it completely. People can only barely deal with more than 2,000 entrances and exits connecting the inside and outside.

The largest entrance and exit, with a diameter of 34 meters, is located in the middle and upper part of Noah, while the smallest is only a few dozen centimeters.

The area where people hide must be completely isolated with radiation-proof walls, and it is best not to be directly exposed to these entrances and exits.

As for the rest, they can only trust Noah unconditionally... If Noah is cracked, no matter how thick the radiation-proof wall is, it will be useless, and humans will definitely be finished.

Think about it, under the effect of ultra-high energy, even a planet with a diameter of several thousand kilometers can be completely destroyed. Even if the radiation protection wall is tens of thousands of meters thick, what's the use?

"...Do you have anything else to add? Do you have any questions?"

It's urgent. Although there are still about four months, Yu Yifeng has deeply felt the urgency of time. If there is nothing to add, he will give the order directly.

"I think we should also consider the situation after we survive successfully."

"If we fail, everyone will die in an instant. There is nothing to worry about. What if we succeed?"

The speaker was Wang Yufan. He pondered for a moment and said anxiously: "By then, the entire solar system will no longer exist. We will not get any resource replenishment. We will face an empty solar system."

"Unless... we can fly to another star!"

"But our technical conditions are simply not enough! Even if our spacecraft flies to Proxima Centauri, it will take tens of thousands of years!"

That's right. If the sun explodes, Noah and mankind will face an empty solar system. There will be no more material replenishment. Humans can only slowly starve to death in the Milky Way.

Yu Yifeng frowned and thought about it. There is really no particularly good way to solve this problem... Tens of thousands of years of flight time is too long.

Supplies, we must replenish supplies like crazy, without supplies, humans can't survive!

In other words, in the past four months, humans must dig like crazy, using all tricks to dig, digging as much as they can!

"Fuck..." Yu Yifeng cursed in his heart, fortunately they have been mining all the time, and it has lasted for nearly three years. The material reserves in Noah are still rich, if they save a little, it can last at least two or three hundred years.

But what will humans face after two or three hundred years? How can humans survive without material resources?

"Regarding this problem... I just designed a simple model."

"This problem will not actually occur."

The speaker was Dr. Rambo, who gestured with a pen, "If our Noah did not explode due to the extremely high heat and pressure, it would most likely be blown away... directly blown out of the solar system."

"This is because the density of Noah is very, very small, even much smaller than a hydrogen balloon, so that it can easily float in the atmosphere of Mars. Let me use a ping-pong ball as an analogy. If a nuclear bomb explodes next to a ping-pong ball and the ping-pong ball does not explode, what will happen to it?"

"It will be blown away by the shock wave generated by the explosion!" Dr. Rambo gestured

"By analogy, our Noah is the same. The powerful and endless light pressure generated by the stellar explosion will quickly push the spacecraft, accelerating it to sub-light speed, or even close to the speed of light!"

"Thus... escape from the solar system!"

This principle is very simple, but no one thought of it for a while, and Dr. Rambo first brought it up.

In other words, if it really survives, Noah is at least moving, and humans will not be trapped in the empty solar system and wait for death.

Many scientists have tried to build models and analyze specific results. The overall density of Noah is so small that it is almost the same as interstellar dust. What Rimbaud said makes sense.

"... According to the relevant theory of supernovas, it is indeed possible to push out the surrounding interstellar dust at a speed close to the speed of light. If Noah does not explode or melt, it will indeed be pushed out by endless gamma rays... accelerated to sub-light speed or near light speed!"

"If we find a planet suitable for living during the movement, we can use the transcendent deceleration plan to quickly slow down the spacecraft!"

Talking about this, many people are actually excited. This is real interstellar travel, and it has been achieved inexplicably? !

However, people still have to be prepared for a protracted war. No one knows where Noah will be blown to, and how many years it will drift before encountering a planet.

No one knows whether Noah will explode?

Mining, still have to mine!

Finally, Yu Yifeng officially made the decision, "Well then, prepare for both scenarios, and start now!"
