Chapter 581

Looking back on the past, Zhang Yuan suddenly found that in fact, every progress of civilization is at the expense of some people's sacrifice.

In addition to nuclear weapons, addictive drugs and virtual world, there is another kind of black technology that has been ignored by human beings, namely toxic fuel.

What is toxic fuel? That is to say, if we only look at the chemical principle of rocket propellant, the most ideal fuel is fluorine. For example, fluorine reacts with hydrogen to produce hydrogen fluoride, which releases a lot of energy.

But it's highly toxic! Skin contact tens of milligrams need amputation, hundreds of milligrams directly did not save, you can prepare for the future.

The fuel of Long March 5 is about 800 tons. If it is launched once with fluorine, if it is accidentally leaked, it can kill hundreds of millions of people.

The size of Saturn 5, you can take the human with the pot!

Organic compounds such as pentaborane and methylmercury are often used as fuel additives. According to the early design, hydrazine fuel should be used with mercury. If the fuel for launching a rocket is leaked, it can pollute the territory of a province.

So, why do you want to do something so dangerous? Because without these things, the thrust of the rocket is not enough and it will not go at all.

In the seventies of the 20th century, it was such a time of competition and a little sad. People were scared to launch rockets in battle, for fear of large-scale pollution after failure.

Fortunately, mankind has passed through the most dangerous time, and space technology has been developing for generations. Toxic fuel has long been abandoned and turned into hydrogen and oxygen fuel.

Even rocket technology has been slowly abandoned

With the emergence of curvature engine, human beings naturally move towards a higher sky and become a real four level civilization.

Zhang Yuan looked at the starry sky in the dome of the coffee shop and stretched lazily, as if embracing the future.

No, it's already embracing the future!

A new era is slowly beginning

……

With the birth of curvature technology, the footprints of human beings will be scattered around the corners of this planetary system in a few years!

In the past, it would take several years to go from one planet to another by the slow ion engine alone. It is impossible to explore every planet here without hundreds of years.

Thanks to the new means of transportation, there are a large number of explorers yearning for the distance in the human community, who have found the best scenery of this planetary system.

For example, a big comet named "Bali baga bar" is composed of rocks and ice. Its color is like a super large cream cake, especially the side facing the sun, which is steeply like a pink cut cake!

There are many young people like to climb to the "cut cake" to take photos.

There is also a planet called "medala", which has a very strong magnetic field. The solar wind blown by the star often draws brilliant Aurora above its atmosphere.

In fact, humans do not intend to settle down in this place for a long time, so most of the planets will not be developed. Instead, they provide natural exploration places for these tourists

“…… Dear passengers, please note that we are now arriving at the site of the second branch of the new human race. Please put on your spacesuit and get off the spaceship orderly. "

This is the star chosen by the galaxy branch. Because the gravity environment of this planet is similar to that of the earth, it will be more comfortable for human beings to live on it, so the whole base of new human civilization has long been replaced by a planet.

Human beings live on one side of the planet, and the ruins of the second branch, on the other side of the planet, have gradually become a tourist attraction.

Here, people can see the ruins and experience the stories that happened.

Zhang Yuan and Lin Xuanxuan came to this human site on a rare holiday.

"At that time, did you think that would happen?" Seeing the devastation, Lin Xuanxuan asked in a low voice.

Zhang Yuan was stunned and said, "what if you expect The power of an era will not change because of prediction. What should happen will happen. But now it's a good result. We have to look ahead. "

Lin Xuanxuan asked a little suspiciously: "since you expect this possibility, why don't you take some measures to stop it? Did you expect it to happen? "

Zhang Yuan shrunk his neck and sighed: "to put it a little worse, the decline of a human branch is not meaningless..."

Among the people coming and going around, most of them are middle school students and primary school students. Many of them are very excited to go out of school for the first time. But when they entered the site, they did not dare to make a sound.

His voice gradually lowered: "it will only make us move forward more steadfastly."

"Why? Can you tell me? " Lin Xuanxuan knew that her husband was the kind of person who was very cruel to big things. Most of the time he's friendly, but a small part of the time, human life is just a number to him."Why..." Zhang Yuan thought for a moment, "when we old guys came together, we suddenly found that, no, human beings will degenerate Later, I found out that this is actually better. It's no big deal. "

"First, you see, our population has expanded to 100 million at present. With this happening, the 100 million people have become high-quality people with upward ideology."

"This kind of high-quality population can not be produced by education alone."

"Second." His voice became more hoarse: "in the future, this group of people will have a higher probability of passing the examination of extraordinary people. Even if it's one percent, there are a million extraordinary people, which is really good. "

"So, if it doesn't produce the best, it will produce There is always someone to light the road ahead. Four level civilization is far from the point. "

Lin Xuanxuan stopped talking and sighed.

The site was not deliberately repaired. It was allowed to decay slowly. There was more and more dust, more and more rust, and only a few electric lights were very dim.

It's the first time that children have felt the power of time so deeply.

The teachers are handing out cleaning tools for them to clean up.

There is also a hibernation warehouse in front of us. There is a lady frozen in it like a sleeping beauty with a faint smile on her face. It is stated in the will that she voluntarily put it here to teach later generations. She's a good person and a bad person.

When children see these eternal hibernators, they have a real fear

It's a real fear, out of my instinct.

"She will never wake up. It's like having a wonderful dream..." Lin Xuanxuan said with a little sadness, "what is human self-consciousness?"

"It should be a kind of randomness that can create information..." As an expert in this field, Zhang Yuan has his own explanation: "pure information will not create more information. The generation of information must come from the real reality."

"Randomness, a way of generating information, is a kind of reality. Self consciousness must be combined with the existing information to give birth to the real human information. "

"So, after losing self will, this person looks like a vegetable, because her brain can't create more information of her own."

"Because randomness is a kind of reality, we now think that the virtual world is also real, so it can give birth to new life."

Zhang Yuan stopped for a moment, and said: "now the virtual laboratory is trying to study a kind of pseudo-random, that is, to install part of the robot software into the human brain."

"By then, these vegetative people will be able to" resurrect "again. They can run, jump, talk and sing. But they are all weak artificial intelligence without randomness, which can't be distinguished by human beings under normal conditions

Lin Xuanxuan can't help shivering. She has an instinctive panic attack. Looking at her husband, she looks like a crazy scientist.

This kind of research Of course, there is meaning.

She patted Zhang Yuan, and the power armour made a "bang" and asked, "are you the legendary Fake people? You have to tell me, how can I tell if I'm sleeping with a real person or a fake person? "

"It's a fake. Really, I've used the first generation of high technology!"

Zhang Yuan felt that he was joking a little too much and quickly ran away
