Chapter 590
Zhang Yuan recalled the past, and suddenly realized that in fact, every progress of civilization comes at the expense of some people.
The two talked about the black technology that once appeared. In addition to nuclear weapons, addictive medicine, and virtual worlds, there is actually a black technology that has been ignored by humans, that is-- Toxic fuel.
What is toxic fuel? That is, the propellant of the rocket, if you just look at the chemical principles, the most ideal is the fluorine fuel. For example, fluorine reacts with hydrogen to produce hydrogen fluoride, which releases a lot of energy.
However, this thing is very poisonous! Skin contact with tens of milligrams requires amputation, and a few hundred milligrams will not help directly, and you can prepare for funeral.
The Long March 5 fuel is about 800 tons. If fluorine is used, it can be launched once. If it is accidentally leaked, it can kill hundreds of millions of people.
The size of Saturn V can carry humans together!
There are also organic substances such as pentaborane and methylmercury that are often used as fuel additives. According to the early design, hydrazine fuel must be used in conjunction with mercury. If the fuel for a rocket launch, if it leaks, it can pollute the land of a province.
So, why do you want to do such a dangerous thing? Because without these things, the rocket's thrust is not enough and can't go up at all.
In the 1970s, it was such an era of competition and a bit sad. Everyone launched rockets trembling in fear for fear of large-scale pollution after failure.
Fortunately, human beings have passed through the most dangerous time tremblingly. Aerospace technology has also been developed from generation to generation. Toxic fuels have long been abandoned and turned into hydrogen-oxygen fuels.
Even rocket technology has been slowly abandoned...
The emergence of the curvature engine makes mankind move to a higher sky logically and become a real Level 4 civilization .
Zhang Yuan looked towards the starry sky of the coffee shop dome, stretched lazily, as if embracing the future.
No, already embracing the future!
A new era is slowly pulling out the curtain...
……
The birth of curvature technology will enable human beings’ footprints in a few years All over the corners of this planetary system!
If you put it in the past, it would take several years to go from one planet to another edge planet by relying solely on the slow ion engine. There is no more than a hundred years is impossible to make every planet here. Fumbled again.
Thanks to the new type of transportation, a large number of explorers yearning for distant places have appeared in the human community. They have found the best scenery in this planetary system.
For example, a big comet named "Bali Baga Bar", it is composed of rocks and ice, its color is like a very large yellow milk cake, especially back The side of the sun is as steep as a piece of pink cake!
There are many youngsters who like to climb to the "cut cake" to take pictures.
There is also a planet called "Middalas", which has a very strong magnetic field. The solar wind blown by the stars often draws brilliant aurora above its atmosphere.
Humans do not actually intend to settle in this place for a long time, so most planets will not be developed, but they provide natural adventure places for these tourist hobbyists...
"... …Please note, all passengers, the location we are now arriving at is the site of the second branch of the New Mankind. Please put on your spacesuit and go to the spaceship in an orderly manner."
This is the planet selected by the branch of the Bright Galaxy. Since the gravity environment of this planet is similar to that of Earth, humans will be more comfortable living on it, so the entire base camp of the new human civilization has long been replaced by a planet.
Humans live on one end of the planet, and the site of the original second branch, at the other end of the planet, has slowly become a tourist Holy Land.
Here, people can see these ruined ruins with their own eyes and experience the stories that have happened.
Zhang Yuan and Lin Xuanxuan took advantage of the rare vacation to come to this human site.
"At that time, did you think that this kind of thing would happen?" Lin Xuanxuan asked quietly, seeing the devastation all over her face.
Zhang Yuan was stunned, "What do you expect...The power of an era will not change because of predictions, but what should happen will happen. But now, the result is pretty good. Well, we have to look forward."
Lin Xuanxuan asked suspiciously: "Since you anticipated this possibility, why not take some plans to prevent it from happening? Have you expected it to happen?"
Zhang Yuan shrank his neck and sighed: "It's a bit ugly. The decline of a human branch is not meaningless..."
p>
Among the people around to-and-fro, most of them are middle school students and elementary school students. Many of them are out of school for the first time and are extremely excited. But when they walked into this ruins, they dared not speak out.
His voice gradually lowered: "It will only make us move forward more steadily."
"Why? Can you tell me?" Lin Xuanxuan knew that her husband was like that. People who treat major events very coldly. Most of the time he is friendly, but a small part of the time, life is just a number for him.
"Why..." Zhang Yuan thought for a while, "At that time, we and the Old Guys together, we suddenly found out, no, human beings will fall partly... Later I found out that this is actually better. There is nothing at worst."
"First, you see, our population has swelled to 100 million. With this happening, the population of 100 million has become an ideology. Upward high-quality population."
"This kind of high-quality population can not be produced by pure education."
"Second." His voice became more hoarse Someone said: "In the future, this group of people will have a higher probability of passing the transcender assessment. Even if it is 1%, there will be one million transcenders, which is really good."
" Therefore, if this matter is not produced, it is the best, then it will be produced...There is always someone to light up the road ahead. Level 4 civilization is far from the point."
Lin Xuanxuan stopped talking, just sighed.
This site did not deliberately repair it, but let it slowly decay and become more and more dusty, more and more rust, and only a few electric lights are quite dim.
This is the first time that children have felt this power from time.
The teachers are distributing cleaning tools for them to clean up.
There is also a hibernation cabin in front of her. 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 provide lessons for later generations. She is a good person and a bad person.
When the little child saw these eternal hibernators, he had a real fear...
This is a real fear, beyond my instinct.
"She will never wake up, as if she was having a good dream..." Lin Xuanxuan said a little sadly, "What is human self-consciousness?"
"It should be a kind of randomness that can create information..." Zhang Yuan, as an expert in this field, has his own explanation: "Simple information will not create more information. The generation of information must It comes from real reality."
"And randomness, which is a way of generating information, is a kind of truth. Self-awareness must be combined with existing information to give birth to a real human being Information."
"So, after losing her 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 paused, then said:" Now Unreal Lab is trying to study a kind of pseudo-random, that is, to install part of the robot software into the human brain."
"When the time comes, these vegetatives can be "resurrected" again. , They can run and jump, and they can also talk and sing. But they are some weak artificial intelligence without randomness. Humans cannot distinguish between them under normal conditions. They are called pseudo-humans for short."
Lin Xuanxuan shuddered uncontrollably, and her instinctive horror valley psychology broke out. Looking at her husband, she was like a mad scientist.
This kind of research...Of course it has meaning.
She patted Zhang Yuan, and Power A issued a light sound "Bang Dang" and asked: "Are you a legendary...fake person? You have to tell me how to distinguish between being with me Is it a daoist or a dummy?"
"It's a dummy, really, I have used the first generation of high-tech!"
Zhang Yuan feels like he is joking It’s a bit too much and ran away quickly...
