However, once the longevity plan is implemented, the divorce rate in human society will soar and the marriage rate will soar, and the increase in fertility rate brought about by artificial uterus will be greatly hedged.

Anyway, no matter what, the ethical approval of artificial uterine technology will be approved in the near future.

After the technology is mature, the first batch of infertile couples will give priority to enjoying this technological dividend.

Of course, these parents also need to pay some risks. The success rate of the first batch of more than 100 children was about 70%. The rest were all killed unexpectedly due to various reasons.

Fortunately, no major accidents such as cerebral palsy occurred, and the fetal genetic diseases can be detected and screened in time.

Professor Tang took a deep breath and looked at Professor Mary again: "The success rate of the first solution will continue to improve with the accumulation of experience, and will eventually rise to more than 99%. It is not considered an essential difficulty..."

"But we have a second view at present, extending the time the fetus grows in the artificial uterus to 21 months."

"You mean... I will give birth after 21 months of pregnancy?!" Zhang Ran's heart beats rapidly. OK, I have to take responsibility for challenging ethics again, right?

Technological progress is always a double-edged sword...

Tang Ze nodded and smiled, "We humans are actually a very strange race."

"The average brain capacity of Homo sapiens infants is 1350 ml, and the pregnancy period is theoretically 21 months. However, the size of the human pelvic opening determines that the maximum fetal brain capacity cannot exceed 385 ml, otherwise the mortality rate will be significantly increased."

"That is to say, because the human fetus' head is too big, if the fetus is born again at 21 months of pregnancy, it will not be born, resulting in the death of both mother and child, which will obviously lead to the extinction of human beings."

"So the genes stipulate that one can only give birth after 10 months of pregnancy. Nowadays, human babies are just premature babies."

"But if artificial uterine technology is used, we can find ways to make the fetus full term, that is, 21 months, grow to about 20 kilograms. This kind of child can crawl when born, walk upright after one month of birth, and speak simple words, fully mature stomach and intestines, eat some complementary foods, have excellent immunity, and are not prone to illness."

"Ha?!" Zhang Ran was shocked. A 20-pound baby can walk when he was born and can eat complementary foods directly... This...

He imagined that after a long time, a 20-pound giant baby who had just been born could crawl at high speed on the ground and call him mom and dad, which made him feel very strange.

Even he himself claims to be very open and accepts advanced ideas very much, and he is a little unable to accept such sudden changes.

The female professor Mary, who stood beside her, bowed slightly, pulled a male worker in a white coat, her husband, and said with a smile: "Your Highness, although it sounds strange, we are talking about facts. In nature, mammal fetuses such as tigers, elephants, cattle, horses, and sheep can stand up as soon as they are born, which is in line with the laws of nature."

"A juvenile body like a human baby is actually very rare, almost only humans. Pregnancy is 21 months in line with science and nature."

"But now, through artificial uterus, we can completely make up for the congenital deficiencies and allow the fetus to be fully termed!"

"In addition, systematic early education and prenatal education may be able to improve the average intelligence of the entire race... maybe, just speculation."

"Our robots can imitate the voices of their fathers and mothers and play music. The early education effect is obviously much better than that of ordinary families."

"My husband and I are willing to try this kind of childbirth... Even if there are problems in the middle, we will carefully raise the child. So we hope that the science and technology ethics department can approve this application."

"I don't count on the ethical issues, I need to vote on the ethics committee... After all, I'm not a professional scientist."

Zhang Ran did not agree immediately or reject it immediately. Could it be that he could improve his IQ a little?

Even if it is 5 percentage points or 10 percentage points, it is still good...

"But why do human babies do this? Don't you think it's a bit strange? The Sibadi and Green Star people have not had such incredible physiological phenomena, right?"

"It's really a bit strange. The human brain is still undergoing huge changes at the age of 18. He is not very good at dealing with psychological stress in his 20s and is easily affected by mental disorders. These problems will gradually be solved by the age of 30. It's just that some people are earlier and some people are later. In other words, humans are not considered to be completely grown up until they are around 30."

"Anyway, staying in an artificial uterus for 21 months is indeed scientifically based."

When he walked out of the New Human Laboratory, he was in a daze and was a little confused about the pros and cons of this solution.

Are the challenges facing human society in the future, especially ethical challenges, too big?

...

Zhang Ran felt that he was dealing with a mess at the moment.

But this is the huge change brought about by technological development!

The silicon universe environment in which the Dongfang Panshi is located is still acceptable to humans, but no trace of the enemy has been found so far.

What really makes the top government officials scratch their heads is the new biological technology in the new era. Longevity technology is about to succeed. It is expected that everyone can live to 300 years old, and there is a subsequent shaping warehouse that can also make people live long. The first phase of artificial uterine technology experiment has also ended, and it has been widely praised by infertile patients...

What other 21-month human fetal growth plans are there...

Everyone who sees this plan will immediately think “What is this”?!

Wouldn’t a 21-month-old human fetus violate the laws of nature?

There are also many differences within the government. Once the choice is not good, internal chaos will inevitably be brought about.

But we must make a decision as soon as possible. After all, both technologies represent the potential of mankind's future.

Longevity technology is time-limited. The older people, the worse the life-lived effect. The entropy increase in the human body is difficult to reverse, and the D factor only slows down the entropy increase.

The life-extending effect is the best in the 20-30-year-old period, and it will gradually deteriorate after this.

Therefore, while everyone is still young and using this technology early can make more people live longer, which is also a very realistic problem.

As for the 21-month human fetal growth plan, it affects the population birth rate and population quality of the next generation, and it must also be made as soon as possible.

"Anyway, we must discuss the results within half a year, introduce what kind of excessive policies and formulate corresponding laws, and we must usher in the transformation of human civilization! As long as the degree of chaos is limited, it is acceptable."

"It is impossible to avoid confusion at all. How can we not have a pain period if we want to build a strong civilization? It really doesn't work. Just like learning from the Green Star civilization and learning some of their systems, they are also long-lived species..."

In the end, these experts could only pinch their noses and rack their brains to think about policies.

The bad thing is that human technology is developing too fast. Originally, these things may have taken hundreds of years and the slow transformation of more than ten generations, but now a generation is going to force the transformation, which has brought a great impact on human society.

But who can refuse to live longer? Who can refuse to give birth to women that no longer requires women to suffer pain and finally liberate women's fertility pain?

This is science, science has changed everything!

Since the first industrial revolution in the 19th century, with the beginning of the scientific explosion, in Isaac Newton's "Mathematical Principles of Natural Philosophy", mankind has seen the world clearly from ancient ignorance for the first time, or at least through a narrow window, and seen the infinite possibilities of the future.

It is precisely because of this that Isaac Newton is always the first person to be at the level of pioneering the world in the history of science.

Einstein, who was famous and established a relativity system, could only sit in the second place.

And science is the ladder and tool to this infinite possibility!

...

That's it. After one meeting after another, Zhang Ran yawned and returned to the captain's office of the Oriental Panshi to review the recent construction report. The restoration project of the curvature device was quite smooth and it is expected to be completed in two months.

With the experience of the last time, scientists tried to modify some unreasonable structures, and the stability performance of coping with the next space turbulence will be higher.

Next, I was really tired, so I just lay on Jelly and took a nap.

Now, human internal affairs can be done to the best. As for changes in internal thoughts and ethical challenges, Zhang Ran no longer wants to oversee it.

Anyway, no matter how it is, humans cannot become extinct due to internal reasons. He has enough confidence in this.

Jelly is as gentle as ever, with a skin that is swelling, and she lets Zhang Ran lie on her body motionlessly. Its IQ always stays at the time when a child is six or seven years old. She learns simple addition, subtraction, multiplication and division, and can't learn difficult mathematics even if she is not able to learn it.

However, at this moment, the jelly suddenly felt a sense in the dark, and its entire body trembled violently, just like a roller coaster, awakening Zhang Ran on its body.

"What's wrong? You won't have someone take a nap today? If you want to eat, you have to wait for me to wake up." Zhang Ran's eyes were sleepy.

"Dongdongdongdongdongdong!" Jelly can't speak, but it can make sounds through friction between the tentacles, which sounds a bit like a drumming sound.

"What did you say... something is approaching?" Zhang Ran was shocked and woke up from his sleep.

At the same time, at the observatory located on the Oriental Panstone, the gravitational wave telescope discovered a very strange gravitational structure. It did not emit gravitational forces continuously like a massive star body, but emitted a faint anti-gravity force.

This gravitational structure can only be observed by the gravitational wave telescope when it is very close. Humans are not unfamiliar with this because it is the small universe.
