“...according to the current model, our universe is in a three-dimensional membrane.The strings that form the elementary particles are divided into two types: closed strings and open strings.Gravitational molecules belong to the open string, and its two ends are located in a higher-dimensional membrane, so it can penetrate multiple dimensions.So the gravity looks very weak."

“photons, electrons, quarks, etc. are composed of closed strings, so we cannot leave our three-dimensional universe.”

"It is not known whether there are more closed-stringed substances in other membranes ... for the time being, perturbation detection can only be carried out by the gravitator."The other membrane is actually equivalent to a parallel universe.The collision between the membrane and the membrane is devastating to our universe ... of course we don't need to worry about that for the time being."

In this large-scale popular science lecture, Yu Yifeng is listening with relish.

The study of space and multidimensional universes has always been the focus of development.It also has many areas, such as artificial gravity, antigravity, higher speed curvature navigation, and so on.

Even the transformation of a white dwarf war star must also use dimensionality technology.If there is no way to offset the gravity, all the machinery will be flattened.

At the end of the lecture, the applause...

Time flies, now is the new human calendar in September 723, since the Pangu number opened the escape mode, there have been 63 years of time...

After blowing up an enemy star, the new humans succeeded in disrupting the entire "encirclement network" plan.

On the one hand, the encirclement network has a small breakthrough; on the other hand, the destruction of the war star has also brought a lot of deterrence to a certain extent.

A planet is inexplicably destroyed, and a normal commander has to run over and look at it.Otherwise, this kind of bad luck may come to your head again.

In this difficult communication situation, from the observation of the destruction of the war stars to the voyage of past reinforcements, it often takes several years.

It is clear that in the choice to rescue their own star or to track an enemy that may not catch up, many of the war stars choose the former.

Coupled with the huge spatial distance in the universe, the information is greatly delayed.The news of the destruction of the war stars may take more than ten years to spread throughout the encirclement network, which greatly delays the time and allows the Pangu to escape smoothly.

The whole civilization took another decade to build a planetary curvature engine.The speed of the Pangu movement has also reached 8 times the speed of light.

The huge increase in navigation speed has also made the Llp silicon-based alliance gradually abandon the pursuit.

The future number has also successfully converged with Pangu 40 years ago.

Recalling the moment of destroying the enemy war stars more than 60 years ago, Yu Yifeng still felt a wave of heart surge...

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

The whole planet is in full swing, with the confluence of the future number and Pangu, the affiliated civilization awakens from the hibernation warehouse, and the golden age of great development is coming quickly!

The development of Pangu, bringing a lot of jobs, is too much.

A planet needs to empty the inside by 10%-20%, equivalent to 10 billion tons of material!

Billions of Billions!It weighs eight orders of magnitude more than the future.

This is a huge project, hard work for hundreds of years, not much.

The process of building a planet is also a process of civilization growth, whether it is industry, agriculture, or entertainment.After all, it is impossible to just work without rest.

As a result, the entire shop is getting bigger and bigger, more and more jobs, and there is also a large-scale population shortage.Even if the population of a subjugation civilization undertakes some marginal flexibility, it is still far from enough.

“Frequends...” Yu Yifeng had a slight headache.The thought of the national superhuman plan in the time of the Royal Star did not know whether it was right or wrong.

If there were no plan, the current population would be seven or eight billion, even if it wasn’t one billion.No matter what, the birth rate is even lower, and one or two million is still there.

The result is now...

"But it is not easy to say that without the implementation of that plan, many important scientists are old and dead, these scientists are selected from six billion people on Earth, and none of them are any of them..."

Without the transformation into superhumans, the average intelligence does not reach the level of almost universal genius, as it is now.We are probably as far as the L3 civilization, and the productivity is not even as it is today.”

Yu Yi Feng thought about it and gave up the tangle in this regard, anyway, it was too late to regret it.He also believes that his first choice was the right one.

The results of the 722-year-old census report show that over the years, the number of new human populations has finally exceeded the 6.6 million mark, and the proportion of men and women is basically balanced.

Among them, 5.2% of the population is still studying in schools and is not very useful.The rest is basically high-quality people.

The population of indigenous lizards has increased by about 26%, bringing the total to 60 million.

I have to say that this figure is seriously lower than expected, and it has only increased the population by 26% in more than 60 years.

In contrast, a strange scene happened.The red-inflammated horns with lower reproductive capacity are even higher, and there are even second and third births, with a total population of about 1.8 million.

Population is a serious issue.With such a total population of less than 100 million, the transformation of the whole planet is still a little difficult.

Soon, researchers involved in a series of scientific studies on this phenomenon.

It has been found that the low birth rate of lizards is due to a series of results caused by the scientific and technological dividend.

Science and technology are becoming more and more developed, life is getting better and better, and the concept of having children's old age no longer exists.

However, the more advanced, the higher the relative cost of raising children, the lower the rate of return.

At this stage, for lizards, raising a child is not only to feed, but also to raise well.Educational resources are always scarce here, making the cost of cultivation of lizards greatly increased.

The second is the length of the breeding cycle, which also makes the birth rate lower.In the era of agriculture, ten years old can go down to work, and in the interplanetary era, the age of thirty is still in school, which also brings more burden to the family.

After all, these lizards do not have a completely free communist system.

“The average lifespan of a lizard has increased to 110 years.For more than 30 years, it has been necessary to study for more than 30 years, and then work for 40 or 50 years before I can finally retire, in which case the low birth rate is normal.”

An expert in charge of the census said: “For them, the pressure of life is not small.There are many complaints in internal network forums.”

“Isn’t there pressure on our children?”But neither can I read.”

Yu Yifeng hands: "Do not read, even planting fields, now are science and technology planting."Do we want to keep them for free?It is impossible...”

“Intelligent life is always greedy, and they want better welfare, it’s normal.”Give more, more value!”

“Better treatment, including life extension, is not difficult for us, but only if we pay enough to help them...”

Relatively speaking, the birth rate of the red-inflammatory horns is higher because of the higher sense of crisis.This civilization subconsciously Hexi comparison, from the population side has always been weak, the industrial side is also weak, after all, the affiliated civilizations, has always been full of competition and cooperation between the state.

This hidden sense of crisis has always encouraged a large number of births within civilization.

Most importantly, the natural life of the red-inflammatory horn is very long, and even if there is no special means to extend life, it can survive for more than 300 years.In this contrast, more than 30 years of study time is slightly acceptable.

“The regulation of population policies will continue, but how it will develop in the future and let them solve it on its own, we still don’t care more about it.”
