Start a Subspace

However, once the longevity plan is implemented, the divorce rate in human society will soar and the marriage rate will drop sharply. The increase in fertility rate brought about by the artificial womb will be greatly offset.

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

After the technology matures, the first batch of infertile couples will enjoy this technological dividend first.

Of course, these parents also need to pay some risks. The first batch of more than 100 children had a success rate of about 70%, and the rest died unexpectedly due to various reasons.

Fortunately, there was no major accident such as cerebral palsy, and the genetic disease of the fetus could 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 increase with the accumulation of experience, and eventually rise to more than 99%. It is not considered an essential difficulty. ..."

"But we currently have a second view, extending the growth of the fetus in the artificial womb, up to 21 months."

"You mean... to give birth after 21 months of pregnancy?!" Zhang Ran's heart was beating fast, okay, I have to bear the responsibility of challenging ethics again, right?

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

Tang Ze nodded and said with a slight smile, "We humans are actually quite a strange race."

"The average brain volume of a Homo sapiens baby is 1350 ml, and the gestation period is theoretically 21 months. However, the size of the human pelvic opening determines that the maximum fetal brain volume cannot exceed 385 ml, otherwise the mortality rate will increase significantly."

"That is to say, because the head of the human fetus is too big, if the fetus is regenerated after 21 months of pregnancy, it will not be able to be born, resulting in the death of both mother and child. Obviously, this will lead to the extinction of human beings."

"So the genes stipulate that you can only be born after 10 months of pregnancy. Today's human babies are all premature babies."

"However, if artificial womb technology is used, we can find a way to make the fetus full-term, that is, 21 months, and grow to about 20 catties. This kind of child can crawl when born, walk upright after one month, and can say simple things. Words, the stomach is fully mature, can eat some complementary food, has excellent immunity, and is not easy to get sick."

"Huh?!" Zhang Ran was startled. A 20-pound baby can walk and eat supplementary food directly after birth... This...

He imagined for a long time that a 20-pound giant baby just born could crawl on the ground at high speed and call him mom and dad, and he had a very strange feeling.

Even he himself, who claims to be very open and accepts advanced ideas, is a bit unable to accept this sudden change.

Mary, the female professor standing aside, bowed slightly, pulled a male worker in a white coat, that is, her husband, and said with a smile: "Your Highness, although it sounds strange, what we are talking about is Fact. In nature, fetuses of mammals such as tigers, elephants, cows, horses, and sheep can stand up as soon as they are born, which is in line with the laws of nature.”

"Fragile larvae like human babies are actually very rare, almost the only case in humans. Pregnancy of 21 months is in line with science and in line with nature."

"But now, through the artificial womb, we can completely make up for the congenital deficiency and let the fetus reach full term!"

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

"Our robot can imitate the voice of father and mother, and can play music. The effect of early education is obviously much better than that of ordinary families."

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

"Ethical issues, it doesn't count if I say it, it needs to be voted by the ethics committee... After all, I am not a professional scientist."

Zhang Ran didn't immediately agree, nor did he immediately veto it. Can it actually increase IQ a little bit?

Even 5 percentage points, 10 percentage points, is good...

"But why do human babies behave like this? Don't you think it's a little strange? The Sibadi and the Green Stars didn't have such incredible physiological phenomena, did they?"

"It's kind of weird that the human brain is still undergoing massive changes at the age of 18, and in the 20s it's not very good at dealing with psychological stress, it's very easy to be affected by mental disorders, and these problems will gradually be resolved by the age of 30 or so, but some Some people are earlier, some people are later. In other words, humans do not fully grow until they are about 30 years old."

"In short, there is indeed a scientific basis for staying in an artificial womb for 21 months."

When he walked out of the new human laboratory, he was in a trance, and he was a little confused about the pros and cons of this plan.

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

...

Zhang Ran felt that he was currently dealing with a mess.

But this is the huge change brought about by the development of technology!

Human beings can accept the environment of the silicon universe that the Dongfang Panshi is in. Anyway, no trace of the enemy has been found so far.

It is the new biological technology of the new era that really makes the top government scratch their heads. The longevity technology is about to succeed. It is estimated that everyone can live to 300 years old, and there are follow-up plastic warehouses that can also make people live longer. The first phase of the artificial womb technology experiment has also ended, and it has been widely praised by infertility patients...

What else is the 21-month human fetus growth plan...

Everyone who sees this plan will immediately think "what is this?" !

Doesn't the 21-month-old human fetus violate the laws of nature?

There are also many differences within the government. Once a bad decision is made, it will inevitably bring about internal chaos.

But a decision must be made as soon as possible. After all, these two technologies represent the potential of the future of mankind.

Longevity technology is time-limited, the older the person, the worse the effect of life extension. The entropy increase of the human body is irreversible, and the D factor only slows down the entropy increase.

During the period of 20-30 years old, the life extension effect is the best, and it will gradually get worse after that.

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

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

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

"It's impossible to avoid chaos at all. If you want to build a powerful civilization, how can you not have a painful period? It's really not possible, just like the green star civilization learning, 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 the development of human science and technology is too fast. Originally, these things may take hundreds of years and a dozen generations to slowly change, but now a generation is about to force the transformation, and the impact on human society is particularly large. big.

But who can say no to a longer lifespan? Who can refuse the technology that no longer needs women's painful childbirth, and finally liberates women's childbearing pain?

This is science, science changes everything!

Since the first industrial revolution in the nineteenth century, with the beginning of the big bang of science, in Isaac Newton's "Mathematical Principles of Natural Philosophy", human beings have seen the world clearly from ancient ignorance for the first time, or It is said that at least through a narrow window, I can see the world clearly and see the infinite possibilities of the future.

Because of this, Isaac Newton will always be the first person in the history of science.

Einstein, who is famous and established the system of relativity with one hand, can only sit in the second place.

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

...

Just like that, after one meeting after another, Zhang Ran yawned and returned to the captain's room of the Dongfang Panshi to review the latest construction report. The repair project of the curvature device is going smoothly, and it is expected to be completed in another two months.

With the previous experience, the scientists tried to modify some unreasonable structures, and the stability against the next space turbulence will be higher.

Next, I was really a little sleepy, so I just lay down on the jelly and took a nap.

Now the internal affairs of human beings can be done to the best of their ability. As for the changes in internal thoughts and ethical challenges, Zhang Ran no longer wants to take care of them.

Anyway, no matter what, it is impossible for human beings to become extinct due to internal reasons. He has enough confidence in this.

Jelly was as docile as ever, her skin was elastic, and she let Zhang Ran lie on her body without moving. Its IQ has always stayed at the age of six or seven, and it can learn simple addition, subtraction, multiplication and division, and it is impossible to learn difficult mathematics.

However, at this moment, Jelly suddenly felt a faint sensation, its whole body shook violently, like a roller coaster, awakening Zhang Ran in his body.

"What's the matter, you don't let people take a nap today? If you want to eat, you have to wait until I wake up." Zhang Ran's eyes were sleepy.

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

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

At the same time, the gravitational wave telescope at the observatory located on Dongfang Panshi discovered a very strange gravitational structure. It does not emit gravity continuously like a massive star, but emits a weak antigravity.

This gravitational structure can only be observed by gravitational wave telescopes when the distance is very close. Human beings are no stranger to this, because it is the microcosm.

A small universe floated out of the high-dimensional world! !
