Beneath Deep Space

"...According to the current model, our universe is located in a three-dimensional brane. The strings that form elementary particles are divided into two types: closed strings and open strings. The graviton is an open string, and its two ends are located in higher-dimensional branes. , so it can penetrate multiple dimensions, so gravity looks very weak.”

"Photons, electrons, quarks, etc. are composed of closed strings, so they cannot leave our three-dimensional universe."

"I don't know yet whether there are more closed string substances in other branes... For the time being, we can only detect disturbances through gravitons. The other branes are actually equivalent to a parallel universe. Branes and branes A collision between them would be devastating to our universe...Of course we don’t need to worry about this for the time being.”

In this large-scale popular science lecture, Yu Yifeng was listening with interest.

Research on space and the multi-dimensional universe has always been the focus of current development. It affects many fields, such as artificial gravity, anti-gravity, higher-speed curvature navigation, etc.

Even to transform a white dwarf battle star, dimensional technology must be used. If there is no way to offset gravity, all machinery will be crushed flat.

After the lecture, there was thunderous applause...

Time flies, it is now September 723 of the New Human Calendar. It has been sixty-three years since the Pangu started its escape mode...

After blowing up an enemy battle star, the new humans successfully disrupted the entire "encirclement network" plan.

On the one hand, there was a small breakthrough in the encirclement network; on the other hand, the destruction of the battle star also brought a great deterrent effect to a certain extent.

A planet was destroyed inexplicably. A normal commander would have to run over and take a look, right? Otherwise, this kind of bad luck might happen to him again.

In such a situation where communication is difficult, it often takes several years from observing the destruction of the battle star to sailing over for reinforcements.

Obviously, between the two choices of rescuing one's own war stars or tracking an enemy who may not be able to catch up, many war stars choose the former...

Coupled with the huge spatial distances in the universe, information is greatly delayed. It may take more than ten years for the news of the destruction of the battle star to spread throughout the entire encirclement network. This will greatly delay the time and allow the Pangu to escape smoothly.

It took the entire civilization another ten years to completely build a planetary curvature engine. The movement speed of Pangu also reached 8 times the speed of light.

The substantial increase in sailing speed also caused the LLP Silicon Alliance to gradually give up the pursuit.

The Future successfully merged with the Pangu 40 years ago.

Recalling the moment when the enemy's battle star was destroyed more than sixty years ago, Yu Yifeng still felt waves of excitement...

After listening to this lecture, he returned to the central command headquarters of the Pangu. The reports on his computer had already piled up.

The entire planet is under construction in full swing. With the convergence of the Future and Pangu, the affiliated civilizations awaken from their hibernation warehouses, and the golden age of great development is quickly approaching!

The development of Pangu will bring too many jobs.

A planet needs to be hollowed out by 10%-20%, equivalent to tens of billions of tons of material!

Tens of billions of tons! Eight orders of magnitude heavier than the Future.

This is such a huge project. Hundreds of years of hard work are not much.

The process of building a planet is also the process of civilization growth, whether it is industry, agriculture, or entertainment, they are all needed. After all, it is impossible for a person to work all without rest.

As a result, the entire stall is getting bigger and bigger, there are more and more jobs, and there is a large-scale population shortage. Even if the population of affiliated civilizations takes on some marginalized flexible jobs, it is still far from enough.

"There is a shortage of people..." Yu Yifeng had a slight headache. When I think of the universal superhuman plan during the Auriga era, I don't know if it's right or wrong.

If that plan had not been implemented, the current population would have been seven to eight billion, if not one billion, right? No matter how bad things are, no matter how low the birth rate is, there are still 100 to 200 million people.

The result is now...

"But it's hard to say. If we don't implement that plan, many important scientists will die of old age. These scientists are selected from the six billion people on earth. They are not even one in ten thousand..."

"If we don't transform into superhuman beings, the average intelligence will not reach the level where almost everyone is a genius as it is now. It is very likely that we will still be an L3 civilization until now, and our productivity will not even be as high as it is now."

Yu Yifeng thought for a while and gave up the entanglement in this aspect. It was too late to regret anyway. And he still thinks that his original choice was correct.

The "Census Report Results" of the 722nd year of New Humanity show that after so many years, the population of New Humanity has finally exceeded the 6.6 million mark, and the ratio of men to women is basically balanced.

Among them, 5.2% of the population are still studying in school and are not of much use. The rest are basically high-quality talents.

The population of indigenous lizards has increased by approximately 26%, to a total of 60 million...

I have to say that this number is seriously lower than expected. It took more than 60 years to increase the population by 26%. Isn't this a joke?

In contrast, a strange scene happened. The Chiyanjiao people with lower reproductive capacity have a higher birth rate, and even second and third children. The total population is about 1.8 million.

The population problem is a serious one. With a total population of less than 100 million, it is still a little difficult to transform the entire planet.

Soon, relevant researchers conducted a series of scientific studies on this phenomenon.

It was discovered that the low birth rate of the lizard population is due to a series of results caused by technological dividends.

As technology becomes more and more developed, life becomes better and better, and the concept of having children and providing for old age no longer exists.

However, the more developed it is, the higher the relative cost of raising children and the lower the rate of return.

At this stage, for the lizard people, raising a child means not only feeding it, but also raising it well. Educational resources are always a scarce material here, which greatly increases the cost of cultivating lizards.

Secondly, the lengthening of the breeding cycle also makes the birth rate even lower. In the agricultural era, people could work in the fields at the age of ten, but in the interstellar era, people were still studying in school at the age of thirty, which also brought more burdens to the family.

After all, these lizards don’t have a completely free communist system.

"The average lifespan of lizards has increased to 110 years. They have to spend the first thirty years studying, and then they have to work for forty or fifty years before they can finally retire. In this case, the low birth rate is normal."

An expert in charge of the census said: "For them, life is very stressful. There are many complaints in the internal network forum."

"Stress...don't our children have no pressure? But it's not enough if they don't study..."

Yu Yifeng spread his hands: "If you don't study, you can't even farm. Now it's all about technology farming. Do you want us to raise them for free? It's impossible..."

"Intelligent life is always greedy. It is normal for them to want better benefits. Then make more contributions and have higher value!"

"Better treatment, including extending life span, etc., is not difficult for us, but only by paying a sufficient price can we help them..."

Relatively speaking, the birth rate of the Chiyanjiao people is higher because they have a higher sense of crisis. This civilization subconsciously compares Hexi to Hexi. It has always been weak in terms of population and industry. After all, the subordinate civilizations have always been in a state of competition and cooperation.

This vague sense of crisis has always encouraged mass births within civilization.

The most important thing is that the Red Flame Horn people have a very long natural lifespan. Even without special life-extending means, they can survive for more than three hundred years. In comparison with this kind of longevity, more than 30 years of study time is slightly acceptable.

"Control in terms of population policy will continue, but how it develops in the future is left to them to figure out on their own, and we don't want to worry too much about it."
