Chapter 114 - Two-handed Preparation

The green light civilization could not have imagined that the "remarkable" new human civilization, which seemed to have a higher level of technology than them, would not be able to leave the solar system!

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

In the following meetings, two basic survival routes were established.

Number one, nuke the Greenlight civilization's ships down and stop them from detonating the sun! As for the unknown fleet at the back, one can only take one step at a time and consider it later.

Second, if the bombing plan fails, humanity will retreat to the second best through the Noah ship to force some struggle to see if they can survive the supernova ...

In short, these two paths humans need to prepare. People can't think of the rest more ways for now ...

The problems related to the nuclear bomb have been taken over by Ding Yidong and the others, and now people mainly consider the situation after the failure of the bombing plan.

That is, the situation that they don't want to face the most - supernova!

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

"... Its thickness is of course the thicker the better, a thousand meters or even ten thousand meters!"

A scientist stood up and said loudly, he was in a state of extreme excitement.

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

Oliver also nodded, the ship floating again is a waste of time and a waste of life. When the Noah unharmed to resist the supernova, but the human race died because of gamma radiation, it is a joke.

"Yes, it is necessary to prepare as soon as possible!"

The speaker is Dr. Roman, his expression is also very serious, "I now talk about the issue of radiation protection materials. As we all know, the Mars virus has a very good anti-radiation cloak, an organic metal with 13 times the radiation protection capacity of ordinary lead plates!"

"There has been good progress in the research of this new material in the biology laboratory, and it may be used to build radiation-proof walls ..."

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

Oliver's heart moved, this is a good news!

The penetrating power of gamma rays is very strong, the energy of 1mev of gamma rays in the air after a hundred meters of travel, the intensity only weakened 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. But because of the price of the metal, it is commonly used in laboratories is lead plates.

But the stellar explosion of gamma rays, the highest energy can be up to 100tev! Such an energy level, completely using brute force, it can directly heat the metal plate to vaporization or liquefaction, regardless of what lead plate, uranium plate, direct violent destruction ...

Human beings on the one hand have to hide behind Mars and use the whole planet for shelter.

On the other hand, it has to strengthen the construction of radiation protection walls, and must and its crazy, brutal and barbaric construction of countless radiation protection walls!

"We just have to use the walls to block the living areas as well as the industrial areas. The rest will have to be abandoned." This was the voice of a construction engineer.

Because of the expansion space inside the ship, the surface area inside the Noah was so oddly large that it was impossible to enclose it all. People can only barely cope with the more than two thousand entrances and exits connecting the inside and outside.

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

The areas where people take refuge must be completely isolated by radiation walls, and preferably not within the range of direct exposure to these entrances and exits.

And the rest, can only unconditionally believe in the Noah ... If the Noah are cracked, radiation walls are thicker and useless, the human race is definitely finished.

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

"... Does anyone have anything else to add? Are there any more questions?"

The matter is urgent, although there are still about four months to go, but Oliver has deeply felt the time constraint. If there is nothing to add, he will just give the order.

"I think we also have to consider what happens if we succeed in surviving."

"If it fails, everyone dies in an instant, nothing to worry about, what if it succeeds?"

The one who spoke was Wang Yufan, he pondered for a moment and said with some anxiety, "By then, the whole solar system will not exist, we will not get any resources to replenish, and we will face an empty solar system."

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

"But we simply can't do that with our technological conditions! It would take tens of thousands of years for our ships to fly to Proxima even!"

That's true, if the sun explodes, the Noah and the human race will face an empty solar system, never to be replenished with supplies again, and the human race will have to slowly starve to death in the galaxy.

Oliver frowned and thought about it, for this problem, there is really no particularly good way ... tens of thousands of years of flight time, too long.

Supplies, there must be a frantic replenishment of supplies, without supplies, humans can not survive!

That is to say, this more than four months, humans must be crazy digging, using all the tricks for mining, digging how much is how much!

"Damn ..." Oliver cursed in his heart, fortunately they have been mining all along, has lasted close to three years. The material reserves in the Noah is still quite abundant, if you save a little, at least two or three hundred years to sustain.

But what about after two or three hundred years, what will humanity face? Without material resources, how will humanity survive?

"On this issue ... I have just designed a simple model."

"This problem will not actually appear."

The one who spoke was Dr. Rimbaud, who gestured with his pen, "If, for example, our Noah did not burst because of the super high heat as well as pressure, it would probably be blown ... right out of the solar system."

"This is because the density of Noah is very, very small, even much smaller than a hydrogen balloon, so much so that it can easily float in the Martian atmosphere. Let me use a ping-pong ball as an analogy. If a nuclear bomb exploded next to a ping-pong ball and the ping-pong ball didn't break, what would happen to it?"

"It would be blown away by the shock wave from the explosion!" Dr. Rimbaud made a gesture

"By analogy, the same thing happens to our Noah. The stellar explosion produces a powerful endless pressure of light that will rapidly propel the ship, accelerating it to sublight speed, or even near light speed!"

"And thus ... escape the solar system!"

This truth is very shallow, except that everyone did not think of it for a while, and was first mentioned by Dr. Rimbaud.

That is to say, if it does survive, the Noah is at least in motion, and humans are not stuck in an empty solar system muddling through.

Numerous scientists have tried to construct models and analyze specific results. The overall density of the Noah is so small that it is about the same as interstellar dust, and Rimbaud's words make sense.

"... According to the theory related to supernovae, it is indeed possible to push out the surrounding interstellar dust at a speed close to the speed of light. If the Noah did not burst or melt away, it would indeed be pushed out by endless gamma rays ... accelerated to sublight or near-light speed!"

"If we find a suitable planet for habitation during our movement, we can use the beyond deceleration scheme to quickly slow the ship down!"

Talking about this, many people were surprisingly excited and excited that this was a real interstellar voyage that somehow materialized this way!

However, people still have to be prepared to fight a protracted war, who knows where the Noah will be blown to and how many years of drifting before encountering a planet.

Who knows, the Noah will not explode?

Mining, or mining!

In the end, Oliver formally clapped his hands and said, "Then, two hands prepare, two programs, start immediately!"
