Deep Space Fleet

Looking back on the past, Zhang Yuan suddenly discovered that, in fact, every progress in civilization is at the cost of some people's sacrifices.

The two chatted about the black technologies that had appeared before. In addition to nuclear weapons, addictive drugs, and virtual worlds, there is actually another black technology that has been ignored by humans, that is-toxic fuel.

What are Toxic Fuels? That is, the propellant of the rocket. If we only look at the chemical principles, the most ideal is fluorine fuel. For example, fluorine reacts with hydrogen to form hydrogen fluoride, which releases a large amount of energy.

However, this thing is highly poisonous! Skin contact with tens of milligrams requires amputation, and hundreds of milligrams are directly fatal, so you can prepare for the funeral.

The fuel of the Long March 5 is about 800 tons. If it is fired once with fluorine, this dose can kill hundreds of millions of people.

With the size of the Saturn V, it can handle human beings together!

There are also organic substances such as pentaborane and methyl mercury are often used as fuel additives. According to the early design, the hydrazine fuel was to be used in conjunction with mercury. If the fuel for launching a rocket leaked, it could pollute the land of a province.

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

In the seventies of the 20th century, it was such an era of mutual competition and a little sadness. Everyone launched rockets with fear, fearing that failure would cause large-scale pollution.

Fortunately, human beings trembled through the most dangerous time, and aerospace technology has been developing from generation to generation. Toxic fuels have long been abandoned and turned into hydrogen-oxygen fuels.

Even rocket technology is slowly being abandoned...

The emergence of the curvature engine has made human beings move towards a higher sky logically and become a real fourth-level civilization.

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

No, already embracing the future!

A new era is slowly beginning...

...

The birth of curvature technology has allowed human footprints to spread all over the corners of this planetary system within a few years!

In the past, it would take several years to go from one planet to another marginal planet by relying on the slow ion engine, and it would be impossible to explore every planet here in less than a hundred years.

Thanks to the new means of transportation, there have been a large number of explorers yearning for faraway places in the human community, and they have found the best scenery in this planetary system.

For example, a big comet named "Balibaba", which is composed of rocks and ice, its color is like a super-large creamy yellow cake, especially the side facing away from the sun, which is steep like A pink cut cake!

There are many young people who like to climb on top of the "cut cake" to take pictures.

There is also a planet named "Medalas", which has a very strong magnetic field. The solar wind blown by the stars often draws brilliant and brilliant aurora above its atmosphere.

Humans actually don't intend to settle in this place for a long time, so most of the planets will not be developed, but it provides these tourist enthusiasts with a natural place for adventure...

"...Passengers, please note that we are now at the site of the second branch of new humans. Please put on your space suits and get off the spaceship in an orderly manner."

This is the planet that was once selected by the branch of the Brilliant Galaxy. 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 base camp of the entire new human civilization has long been replaced by a planet.

Humans live on one side of the planet, and the site of the original second branch, on the other side of the planet, has gradually become a tourist holy place.

Here, people can see these gradually dilapidated ruins with their own eyes and experience the stories that once happened.

Zhang Yuan and Lin Xuanxuan took advantage of the rare vacation to come to this human ruins.

"At that time, did you expect such a thing to happen?" Lin Xuanxuan asked in a low voice when she saw the devastation.

Zhang Yuan was stunned, "So what if it is expected... The power of an era will not be changed because of predictions, what should happen will still happen. But now, the result is not bad, we have to ask Look ahead."

Lin Xuanxuan asked a little suspiciously: "Since you anticipated this possibility, why didn't you take some measures to prevent it from happening? You already expected it to happen?"

Zhang Yuan shrank his neck and sighed: "To put it bluntly, the decline of a human branch is not meaningless..."

Among the people coming and going around, most of them are middle school students and elementary school students. Many of them are walking out of school for the first time, and they are very excited. But when they walked into the ruins, they all dared not make a sound.

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 the kind of person who was very indifferent to big things. Most of the time he is friendly, but a small part of the time, human life is just a number to him.

"Why..." Zhang Yuan thought for a while, "At that time, some of us old guys made a calculation and suddenly realized, no, human beings will degenerate to a certain extent... Later, I found out that this is actually better, and it's not a big deal."

"First, you see, our population has now expanded to 100 million. With this incident, this 100 million population has become a high-quality population with an upward ideology."

"This kind of high-quality population cannot be produced simply by education."

"Second." His voice became even hoarse: "In the future, this group of people will have a higher probability of passing the test of transcendents. Even if it is one percent, there are still a million transcendents. That's really nice."

"So, if this matter doesn't happen, it's best. If it happens, it will happen...There must always be someone to light the way ahead. The fourth-level civilization is far from the end."

Lin Xuanxuan stopped talking and just sighed.

The ruins were not deliberately repaired, just let it slowly decay and decay, with more and more dust and rust, and the only few electric lights were rather dim.

It is the first time that the children feel this power from time so deeply.

Teachers are handing out cleanup kits for them to clean up.

There is also a hibernation cabin ahead, and a lady is frozen in it like a sleeping beauty with a faint smile on her face. It was stated in the will that she put it here voluntarily to provide lessons for future generations. She is good and bad.

When children saw these eternal hibernators, they felt real fear...

This is really scary, beyond my instinct.

"She will never wake up, as if she is having a beautiful dream..." Lin Xuanxuan said a little sadly, "What is human self-awareness?"

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

"And randomness, that is, a way of generating information, is a kind of reality. Self-awareness must be combined with existing information to give birth to 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 believe that the virtual world is also real, so it can give birth to new life."

Zhang Yuan paused, and then said: "Now Unreal Labs is trying to study a kind of pseudo-randomness, that is, to install part of the robot software into the human brain."

"At that time, these vegetative people will be able to 'resurrect' again. They can run and dance, and they can also talk and sing. But they are all weak artificial intelligence without randomness, and humans cannot distinguish them under normal conditions. , Abbreviation: Pseudo-person."

Lin Xuanxuan shuddered uncontrollably, and her instinctive uncanny valley mentality broke out. Looking at her husband, she looked like a mad scientist.

This kind of research...is of course meaningful.

She patted Zhang Yuan, and the Power Armor made a soft bang, and asked, "Could it be that you are the legendary...false person? You have to tell me how to distinguish whether the person sleeping with me is a real person or a fake person." ?”

"It's a fake person, really, I have already used the first generation of high technology!"

Zhang Yuan felt that his joke was a bit too much, so he ran away quickly...
