Zhang Yuan is thinking about a question: if anti-gravity technology really appears, will human civilization be able to get rid of the predictions of the historiography of new civilizations? In previous calculations, it seems that this was not taken into account.

John was still there and climaxed to himself: "I'm wondering, is the black hole a Bohr-Einstein condensate at the tipping point of quantum phase transitions?" That's why there are some strange properties...... As Bohr said, when matter falls into a black hole, it can only approach the singularity infinitely, but cannot actually reach the singularity. ”

"It's a little bit of a possibility......"

The two discussed with great interest for a long time before the whole room slowly fell silent.

John, this guy is hard-skinned and stubborn, insisting on maintaining a pessimistic attitude, believing that it is impossible for humans to achieve true anti-gravity technology, and all technological developments are just a flash in the pan.

"Whatever you want......" Zhang Yuan said angrily.

There is no end to debate, there is no end to the battle of words, and it doesn't hurt to have different opinions anyway, and the future of humanity will give the answer.

After reading these scientific and technological news, Zhang Yuan randomly picked a few reports and read them in detail.

Every year, the Deep Space Foundation publishes a special report to conduct an in-depth investigation of 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 Earth Era.

Reading that report is much quicker than searching for news.

As soon as he heard that the Deep Space Foundation still existed, Zhang Yuan suddenly breathed a sigh of relief in his heart. He still has a lot of affection for this organization that has survived.

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

Space exploration has become a very popular activity, with explorers shifting their gaze from regions like Mount Everest and the South Pole to the distant universe.

Distant planets such as Pluto and Sedna can be found in human exploration.

Yes, private spaceships have finally become a real reality!

"Ah, rich people can already buy spaceships, Ye Kaifu's dream has come true...... So what...... The Rock Turtle? ”

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

Zhang Yuan keenly felt the change in this environment. In their time, in the 23rd century, it was still quite difficult for ordinary people to go to space, and they had to spend a lot of money. And in this day and age, space tourism has become commonplace. It can be seen that the productive forces of the whole world have undergone another qualitative change.

Moreover, because of the development of technology and the pursuit of wealth, the degree of fear of the universe of human beings as a whole has also decreased a lot.

The Great Interstellar Age really began, just like the Age of Discovery in the late 15th and early 16th centuries, when the wealth hidden in the universe quickly rolled up a frenzied gold rush and quickly reversed the overall ideology of mankind.

People's fears of the universe are dissipating considerably.

For capital, wealth is more important than life.

The solar system is so vast, and the duration of the Great Interstellar Age is much longer than that of the Age of Discovery.

Zhang Yuan clicked on a report from 30 years ago.

"Hello Earth Age colleagues! In this report, I will describe in detail a series of changes that have taken place in the earth's civilization in recent years. ”

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

"Wood and Saturn have become our nuclear fuel reservoirs, while Mercury, Venus and the Moon have become excellent industrial bases......"

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

"The severe atmospheric greenhouse effect on Venus, and the acid rain environment in Titan, caused major technical problems, and it took us a full 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 here are a bunch of papers on planetary modification projects, including how to improve the atmosphere, if to improve the geological environment, and so on. These are on-the-ground engineering experiences, and they are very, very valuable indeed.

One of the documentaries tells the story of the Mercury development site.

Mercury is a large, natural mine made up 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 an endless amount of energy, even nuclear power plants do not need it, only some solar panels and thermal differential energy devices can produce enough electricity.

Humans, on the other hand, live on the far side of Mercury, where the sun's rays cannot shine directly.

In this documentary, a huge space port stands on the far side of Mercury, and various robots and spaceships are shuttling back and forth, a scene of excitement.

Zhang Yuan was happy in his heart, and he also had a feeling of loss.

This era is more prosperous and prosperous than their time.

The feeling is mixed.

The report continues: "The Earth, on the other hand, is undoubtedly the core of the entire ecosystem around the solar system, as well as the center of talent, trade, and finance. Thanks to the development of the ecosystem around the solar system, the prosperity of the entire civilization has increased a lot. ”

“…… Unfortunately, we currently have too few high-quality industrial populations. The excessively low birth rate has seriously affected the continued development of the entire civilization. The second and third phases of the project are really worrying. ”

"It is simply estimated that we may need a full 60 billion people to fully meet the needs of these planets, but the total population is only 16 billion, and it is in a state of long-term stagnation, and the problem of population aging is getting worse by ......"

"There are many reasons why population growth has stopped. The main reasons for this are the increase in life expectancy, economic problems, and current ideological problems. The more high-quality the population, the greater the cost of cultivation and the greater the burden on families. ”

"I have to admit that many countries, such as our Xia country, have entered a state of aging. That's what worries us the most......"

There are also a series of population reports, including the average life expectancy of each country, the marriage and divorce rates of each country, the distribution of the population, the Engel coefficient, the Gini index, and so on.

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

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

However, for the people of the Xia Kingdom, this is not the point, as long as they can go to space and are willing to endure hardships, they can still easily obtain a considerable amount of wealth, which is enough.

But many of the facts, as the Foundation Director said, are natural and difficult to reverse.
