Chapter 117

Zhang Yuan is thinking about a question: if anti gravity technology really appears, can human civilization get rid of the prediction of new civilization historiography? In the past calculation, it seems that this point has not been taken into account.

John is still there, self-conscious climax: "I wonder, is a black hole a Bohr Einstein condensate at the critical point of quantum phase transition? Only in this way can there be some strange properties Just as Bohr said, when matter falls into a black hole, it can only infinitely approach the singularity, but can not really reach it. "

"It's a little bit possible..."

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

John is a tough guy. He insists on keeping a pessimistic attitude. He thinks that it is impossible for human beings to realize real anti gravity technology. All the development of science and technology is just a flash in the pan.

"Whatever you want..." Zhang Yuan didn't say well.

There is no end to debating this kind of thing, and there is no solution to the argument. Anyway, it's OK to have different opinions. The future human beings will give the answer.

After reading these science and technology news, Zhang Yuan picked out a few 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 in this year, so as to provide more accurate historical samples for the scientists of the earth age.

Reading that report is faster than searching for news.

Hearing that the deep space foundation still exists, Zhang Yuan was relieved. He still has a lot of feelings for this continued organization.

In 183, the human footprint has 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, and explorers have shifted their eyes from Everest, Antarctica and other regions to the distant universe.

Including Pluto and Sedna, we can find traces of human exploration activities.

Yes, private spaceship has finally become a real reality!

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

Of course, you need money to buy a spaceship.

Zhang Yuan keenly felt the change of this environment. In their time, in the 23rd century, it was very difficult for ordinary people to go to space, which cost 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 overall human fear of the universe has also decreased a lot.

The great interstellar age 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 frenzy of gold rush and quickly reversed the overall ideology of mankind.

The fear of the universe is dissipating.

For capital, wealth is more important than life.

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

Zhang Yuandian wrote a report 30 years ago.

"Hello, colleagues of earth age! I am Zhang Jianjun, President of the deep space foundation. In this report, I will describe in detail a series of changes that have taken place in the earth's civilization in recent years. "

"It's my honor to tell you that we have successfully constructed the first phase of the construction of the civilized ecosystem around the solar system!"

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

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

"The serious greenhouse effect of Venus and the acid rain environment of Titan have caused serious technical problems. It took us 100 years to improve the ecological environment of these planets..."

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

The following is a large number of papers on planetary modification engineering, including how to improve the atmosphere, if to improve the geological environment and so on. These are all field engineering experiences, which are very precious indeed.

One of the documentaries is about the mercury development scene.

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 there is no need for endless energy, even for nuclear power plants. Only some solar panels and thermal differential energy devices are needed to generate enough power.

Humans, on the other hand, 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, which is a hot scene.

Zhang Yuan felt happy and disappointed.

This era is more prosperous and powerful than their era.It's a complex feeling.

The report continued: "the earth is undoubtedly the core of the ecosystem around the solar system, as well as a 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 phases is really worrying. "

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

"There are many reasons why population growth has stopped. The main reasons are the growth of life span, 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 country, have entered an aging state. This is what we are most worried about... "

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

Seeing this, Zhang Yuan carefully pondered over the data.

After 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 point. As long as they can go to space and bear hardships, they can still easily obtain a considerable amount of wealth, which is enough.

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