No one knows what the next generation of technology will be.

The so-called scientific subject is the most important factor that triggers the explosion of science.

For example, the first scientific explosion, although historically began with the European Renaissance, in fact, it began with the steam engine, of course, it was called the Industrial Revolution, but isn't human science progressing right next to social progress?

Then to the internal combustion engine, and then to the large-scale use of electricity, so the second industrial revolution broke out, which was the electric power industrial revolution in history, and immediately after this, various sciences based on electricity were launched.

After the second industrial revolution, the third industrial revolution is the leap forward development of atomic energy, electronic computers, space technology and biological engineering, but in the final analysis, in fact, it is the development of electronic computer technology as the soil, so as to produce the scientific industrial revolution, if there is no computer, all kinds of modern science will not have the soil, you can never ask for manpower to calculate the equation that needs to be calculated billions of times, right?

So far, human science is still enjoying the fruits of the third industrial revolution, that is, despite the fact that the third industrial revolution has broken out for decades, but in fact, the current level of science and technology of mankind is still in the period of the third industrial revolution.

So...... What was the flashpoint of the Fourth Industrial Revolution? What is its soil? What is the new scientific explosion triggered by this?

This has caused a lot of discussion in the scientific community, some people say it is biotechnology, some people say it is the generation of new energy, some people say it is the innovation of space technology, some people say it is the formation and generation of artificial intelligence, all kinds of opinions are different, but all scientists have a consensus, that is, when the soil of the fourth industrial revolution appears, human beings are about to usher in a new round of scientific explosion, thus completely completing the fourth industrial revolution.

In fact, Yao Yuan looked at the current vigorous development of the scientific community of Hope, especially the recent wave of inventions, he was very excited, he longed to see the outbreak of the fourth industrial revolution in his lifetime, and to see the emergence of science and technology belonging to the fourth industrial revolution, perhaps...... After the Fourth Industrial Revolution and the outbreak of science, human civilization was a new civilization suitable for space navigation at that time.

Yao Yuan listened to Polly's request, he frowned, and then sat back in his chair and said: "Since you know the existence of those robots, then you should know that these robots are the last and final defense mechanism of the Hope, once any non-humans invade the Hope, these robots will serve as a solid position, and it is the Hope Central Computer that controls them...... I can't answer your request right away, so give me some time to think about it, because it's a matter of life for everyone on the Hope, once the robot's program is rewritten...... You know the consequences. ”

Polly frowned slightly, she didn't say much, bowed her head slightly, and then turned and walked towards the door.

At this moment, Yao Yuan suddenly asked, "Bo Li, you have guided a lot of inventions recently, could it be ...... Are you already feeling the signs of the Fourth Industrial Revolution? Is the frontier of the fourth explosion of human science and technology, as predicted by those scientists? ”

Polly stopped, but she didn't look back, just said, "...... Yes, there is a little speculation and feeling, but whether it is true or not requires me to continue to experiment. ”

Yao Yuan thought for a while and said, "Is it related to Gaussian technology?" In other words, is the fourth industrial revolution an industrial revolution in electromagnetic technology? This requires the complete mastery of new materials, such as high-energy reserve batteries, new energy sources, and electromagnetic technology, right? ”

Polly frowned and said, "I said, I'm not sure, I need more experiments!" ”

"Really?" Yao Yuan exhaled and said, "I will give you an answer within three days." ”

"Okay."

After Polly said this, she walked out of the captain's room by herself, and the moment she walked out of the door, she suddenly said, "There is a small shop selling rice cakes in the C block on the third floor, and I like to eat rice cakes there." With that, she walked out on her own.

Yao Yuan was directly stunned, he shook his head with a wry smile, and began to ponder there silently, after a long time, he suddenly pressed a liaison on the desktop and said: "Call Zhang Heng, Ying, and Heitie." ”

On the third day, in the weapons test field where Polly was, Eagle, Black Iron, and Zhang Heng stood in place in military uniforms, and behind them, there were several complete robots and several piles of broken robot wreckage.

"Captain Eagle, Captain Black Iron, and Captain Zhang Heng, as the guardians and observers of this robot experiment." The eagle took a step forward and said to Polly and the rest of the scientists, researchers, and experimental students with full of energy.

Polly glanced at the three of them, she didn't care, she walked around them and walked to the side of the pile of robots, first carefully stroked the shells of these robots, and then came to the pile of robot wreckage to take a closer look, after a long time she stood up, and said: "Then start with the robot wreckage to study ......"

(The Foreseeer senses danger, the Clear sees any of my actions, and the Senser subdues or kills me in the shortest time...... But it's okay, I'm not going to do anything, I've already said it, that rice cake is the best, I like the Hope very much, that big idiot, as my father said, is very suspicious...... In fact, long before the baby boom began, many people did not buy milk powder, and the issuance of this decree made many people applaud it.

With more than 1,000 urgently trained doctors on duty, the next month's baby birth tide has finally coped with it, so far, the total population of Hope has reached about 140,000, including more than 16,000 babies, and in the next two months, 12,000 to 15,000 babies will be born, by that time, the total population of Hope will reach more than 150,000!

However, the consequence of this is not only the increase in the number of human beings, but also other factors, that is, the size of the Hope Number.

Some experts have clearly pointed out that the total population limit of the Hope is 220,000, once this threshold is exceeded, then the ecological park will not be able to carry all the food sources of so many human beings, even the lowest level of food and clothing can not be achieved, and as the population increases, the load of the air circulation system, waste water and water vapor circulation system, and the subsistence system will also skyrocket.

To survive, people must have enough living space, housing is one of them, jobs, entertainment facilities, and the most basic food sources, etc., all of which challenge the fragile human civilization in front of us.

The Hope is not too big, but ...... It's so small!

However, it is impossible for Yao Yuan to give an order for family planning, first of all, this does not conform to the psychology of most European and American people, and secondly, the number of human beings is only a few hundred thousand, and there is no possibility of a buffer time for family planning, if a generation is family planning, then the population of the next generation will be immediately halved, or at least reduced by three percent, and in this way, at most two generations will let human beings completely finish, not to mention anything else, once genetic diversity is lost, then the proportion of inbred marriage may rise sharply, and at that time, human beings will simply commit suicide, there is no need to encounter any cosmic catastrophe at all.

In general, as those scientists or experts have mentioned, the size of the environment, the number of people, these factors are the basis for determining the continuation of human beings in the universe.

"It seems that the plan for the external cabin must be implemented immediately."

In order to solve the problem of population growth and the fact that the Hope is too small, relevant experts have proposed a plan for the transformation of the external cabin.

According to them, the plug-in cabin can not only be used to produce all kinds of luxury goods and meat food, but can actually make more plug-in cabins to develop more space for Hope, and the increased space will provide more jobs and living environments.

In fact, these experts clearly pointed out the irrational surname of Yao Yuan's spatial jump.

At present, the Hope is only able to make nearly 400 spatial jumps, and each spatial jump only stays for three days, in other words, if all the spatial jumps are accumulated, and each spatial jump does not encounter anything, then in fact, it can only pass three to four years.

But Hope has been able to survive in the universe for about forty years, and if the energy of the space jump is completely used, what will happen to the remaining thirty years? Do you have unlimited rafting all the time?

Therefore, experts proposed that every time there is a space jump, no matter whether there is anything around, it is necessary to stay in the void for a month, that is, thirty days, during this time, the external cabin can be expanded, thirty days is enough for some plants to grow and harvest, and it can also allow the extra people in the future to live in the external cabin, only when the space jumps to put away the external cabin, let the people return to the Hope, and then expand again after the jump, such a circular mechanism.

If the population is divided in this way, then the Hope can afford the living needs of no more than 500,000 people, and at that time, at least two generations of population have passed, that is, at least more than forty years have passed, and at that time, human beings will either make scientific and technological progress and can already build new spaceships, or they will be completely finished, and human civilization will disappear in the universe, so there is no need to worry about anything.

While Yao Yuan was discussing with the experts about the external cabin, a new report came from Polly's scientific team.

It wasn't that the Gauss weapon experiment was successful, or even that there was any accident, but that the Bolero science team had found a very strange signal, which was transmitted from the complete robot, and its source of acceptance was not the central computer of Hope, but ...... In the mezzanine under the central computer of the Hope!

There was a metal mezzanine inside the Hope, a solid metal layer, but the signal was actually received there, in other words...... There's got to be something in that mezzanine!
