Chapter 120

Zhang Yuan is thinking about whether human civilization can get rid of the prediction of new civilization history if anti gravity technology really appears? It seems that this point has not been taken into account in previous calculations.

John was still there and climaxed: "I wonder if a black hole is a Bohr Einstein condensate at the critical point of quantum phase transition? In this way, there will be some strange properties... As Bohr said, when matter falls into a black hole, it can only approach the singularity infinitely, but can not really reach the singularity. "

"A little bit possible..."

After a long discussion, the whole room slowly quieted down.

John is a hard nosed guy who insists on maintaining a pessimistic attitude. He believes that human beings cannot realize real anti gravity technology, and all scientific and technological development is only a flash in the pan.

"Whatever you..." Zhang Yuan said unhappily.

There is no end to debate this kind of thing, and there is no solution to the debate of words. Anyway, it doesn't matter that they have their own views. Future mankind will give the answer.

After reading these scientific and technological news, Zhang Yuan randomly selected several reports and read them in detail.

Every year, the deep space foundation will issue a special report to deeply investigate the scientific and technological progress and cultural changes of the whole civilization this year, so as to provide more accurate historical samples for the scientists of the earth times.

Reading that report is really much faster than searching for news.

Zhang Yuan was relieved to hear that the deep space foundation still existed. He is still very emotional about this continued organization.

In 183, human footprints have spread all over the solar system. With the innovation of technology and the continuous improvement of productivity, the cost of aerospace industry has been greatly reduced.

Space exploration has become a very popular activity. Explorers have shifted their attention from Mount Everest, Antarctica and other areas to the distant universe.

Including distant Pluto and Sedna, traces of human exploration can be found.

Yes, private spaceships have finally become a real reality!

"Ah, rich people can already buy spaceships. Ye Kaifu's dream has come true... What... Giant rock turtle?"

Of course, you have to have money to buy a spaceship.

Zhang Yuan keenly felt the change of this environment. At that time, in the 23rd century, ordinary people were still quite difficult to go into space and had to spend a lot of money. In this era, space tourism has become a common thing. It can be seen that the productivity of the whole world has undergone another qualitative change.

Moreover, because of the development of technology and the pursuit of wealth, the fear of the universe as a whole has been reduced a lot.

The great interstellar era has really opened, just like the great navigation era from the end of the 15th century to the beginning of the 16th century. The wealth contained in the universe quickly rolled up a fanatical gold rush and quickly reversed the overall ideology of mankind.

People's fear of the universe is dissipating greatly.

For capital, wealth is more important than life.

The solar system is so vast that the duration of the great interstellar era is much longer than that of the great navigation era.

Zhang Yuandian opened a report 30 years ago.

"Hello, colleagues of the earth times! I am Zhang Jianjun, President of the current deep space foundation. In this report, I will describe in detail a series of changes in earth civilization in recent years. "

"I am honored to tell you that we have successfully built the first phase of the civilized ecosystem around the solar system!"

"The wood system and Saturn have become our nuclear fuel bank, while Mercury, Venus and the moon have become excellent industrial bases..."

Even if it is just a written report, I can still feel the president's strong pride.

"The serious atmospheric greenhouse effect of Venus and the acid rain environment of Titan have caused major technical problems. It took us a whole hundred years to improve the ecological environment of these planets..."

"I hope these experiences can provide a good demonstration effect for your interstellar colonization..."

Attached below are a lot of papers and reports on the planetary transformation project, including how to improve the atmosphere, if improve the geological environment, and so on. These are field engineering experience, which is indeed very, very precious.

One of the documentaries is about the mercury development site.

Mercury is a huge and natural mine, composed of 70% metal and 30% silicate. Because it is close enough to the sun, its surface temperature can reach 430 degrees, which also means that endless energy is not needed even for nuclear power plants. Only some solar panels and thermal differential energy devices are needed to produce enough electric energy.

Humans live on the back of mercury, where the sun cannot shine directly.

In this documentary, the huge space port stands on the back of mercury, and all kinds of robots and spacecraft shuttle back and forth. It is a hot scene.

Zhang Yuan felt happy and disappointed.

This era is more prosperous and powerful than their era.

The feeling is complicated.

The report continued: "the earth is undoubtedly the core of the ecosystem around the solar system and the center of talent, trade and finance. Thanks to the development of the ecosystem around the solar system, the prosperity of the whole civilization has increased a lot. "

"... unfortunately, our current high-quality industrial population is too small. The low birth rate has seriously affected the continuous development of the whole civilization. The construction speed of the second and third phase projects behind us is really worrying. "

"It is simply estimated that we may need a full 60 billion people to fully meet the transformation needs of these planets. However, the current total population only reaches 16 billion, and it is in a state of long-term stagnation, and the problem of population aging is becoming more and more serious..."

"There are many reasons for stopping population growth. The main reasons are the growth of life expectancy, economic problems and current ideological problems. The higher the quality of the population, the greater the cost of training and the greater the burden on families. "

"I have to admit that many countries, such as our Xia country, have entered an aging state. This is what we are most worried about... "

A series of population reports are attached below, including life expectancy, marriage and divorce rates, population distribution, Engel coefficient, Gini index and so on.

Seeing this, Zhang Yuan pondered over the data for a while.

After several generations of accumulation, the Gini index, that is, the gap between the rich and the poor, is slowly increasing.

However, for Xia people, this is not the key point. As long as they can go into space, be willing to bear hardships, and still be able to easily obtain a considerable amount of wealth, this is enough.

But many facts, just as the fund president said, the stagnant growth of population is natural and difficult to reverse.
