Deep Space Fleet

For this reason, Mars is not the focus of human beings. There is only such a solitary space city above it. Most of it is scientific research and transit stations.

Martian enthusiasts are thinking of melting two levels of carbon dioxide to improve the atmosphere of Mars and achieve the purpose of future livability.

"If the population explodes after human civilization and the earth and the moon can no longer live, then it will be possible to develop Mars ... Compared to other planets, this planet is better for living. No alien microorganisms have been found at present , Security is okay. "Brother Zhao suddenly said.

Zhang Yuanyuan responded: "I don't think it is possible in the foreseeable future. The growth rate of civilized population is not high."

Within the limits allowed by natural resources, social systems, and productivity, of course, the larger the population, the better, especially the high-quality population.

But capitalism is a birth control pill.

In the old times, limited by resource distress, the earth's population used to stagnate for 7 to 8 billion.

After experiencing the Fourth World War and the "light of nuclear fusion", the entire civilization once ushered in a wave of fertility. But now, the population growth rate has slowly slowed down, and the annual growth rate is less than 1%.

From the current population of 10 billion to 100 billion or even 1 trillion, it is actually very difficult. For many families, having a second child is already a pain.

As for the low-quality population in some countries, no more use it.

Zhang Yuan suddenly wondered: "If artificial uterine technology and robotic rearing are developed in the future, do you think it will change this pattern?"

Brother Zhao shook his head: "Artificial uterine technology has liberated women and is a major technology that affects the entire world. With artificial uterine technology, what feminist movement can finally stop."

"... but I still can't change the fundamentals of population growth. Because the important thing for a child is parenting, not the process of childbirth. Parenting consumes more energy than childbirth!"

"As for machine maintenance, how strong artificial intelligence is this! And, ethics may be discussed for a long time ..."

"I am rather worried about the uterine revolution strategies of some small countries. A large number of foreign immigrants will lead to a decline in the influence of the main ethnic group. Conflicts in ideology and culture are likely to replace bad coins with bad ones. A lot has happened in history This is the phenomenon again. "

Zhang Yuan sighed, "Well, that's true."

I was so wild about the mountains, and I visited the observatory for a while, and Zhang Yuan suddenly found that there was an electronic reading room called "Xingchen Library". A few people were reading inside.

He thought to himself that in this kind of place, those who can still enjoy loneliness must be some top masters. Maybe you can try it later ...

After a random visit, the two turned around and returned to the track car.

的 The end point of this journey is the rear wing of the mother ship, which is where the nuclear fusion engine is located.

The plutonium fusion engine has a maximum ring diameter of more than four hundred meters. Just the tip of the iceberg is enough to make people feel shocked.

When I saw this giant, Zhang Yuan felt his heart became hot.

长期 The long-term work, happiness and sense of accomplishment here are definitely stronger than cleaning the cabin.

On a recent detection screen, a group of blue and white plasma is discharging, and various parameters are displayed nearby.

眯 Zhang Yuan squinted his eyes, and he saw a temperature marked above, about 750 million degrees!

"You are here!"

"Professor Ding."

I saw a figure drilled into the room in front of me, and Zhang Yuan hurriedly greeted him.

Academician Pu Ding is here to understand the changes of various parameters, and just happened to meet them.

"Zhang Yuan, it looks like you like it here. To fully understand this big thing, you may have to learn some mechanics, nuclear physics, plasma, and many things to learn."

Zhang Yuan is quite active, "Can I do some work now?"

"Read some papers first. If you do n’t understand, you can ask your brother. You can also monitor the trajectory of the plasma turbulence here. By the way, you can study the structure of the entire engine. The effects of helium turboexpanders in low temperature systems, etc., can be selected by yourself, and I will open certain database permissions for you. "

"If you fully understand the working principle of the entire engine, the rest of the space engineering will be trivial to you."

Zhang Yuan answered, looking for his seat.

He fixed his body in his seat with interest, trying to find a little paper in the database.

Here, he can even read the control codes of various machines!

Of course, only read permission, no modification permission.

Zhang Yuan was very pleased to find that the entire control project of nuclear fusion was done by his father, and the curiosity and eagerness in his heart were even greater.

He thought to himself: "The work on nuclear fusion sounds high. If Li Zhendong is met, I don't know how long I can brag ..."

Tritium nuclear physics, similar to high-energy physics, is a theory that studies microscopic and deep levels. Nuclear physics is biased toward lateral applications, while high-energy physics is biased toward microscopic, deep-level theories.

But in this era, high-energy physics started to fade away.

The main reason is that you can find it out, but you have gradually figured it out. What you do n’t understand is still unclear.

In the 23rd century, the Xia National Academy of Sciences used to spend huge sums of money to build a larger collider, but the end result was that it couldn't crash any kind of particles beyond expectations. This project became a classic white elephant project.

标准 The standard model based on non-Abelian gauge fields seems to have become the upper bound of human understanding of nature.

According to the estimates of some scientists, if you want to verify a higher-level theory and find some physical phenomena beyond expectations, you need to build a ring solar collider! In other words, ~ www.readwn.com ~ The length of this collider must orbit the solar system.

For humans, it is an impossible task.

This conjecture is called the "energy-level desert" conjecture.

物质 Substances in nature, under different accelerator energies, will have very different properties.

With the energy of 10 electron volts, one can observe atomic disintegration and explosion, decomposing into atomic nuclei and electrons.

In the range of 10 ^ 6-10 ^ 7 electron volts, people can observe that the nucleus disintegrates again and decomposes into neutrons and protons.

Under the energy of 10 ^ 11 electron volts, electroweak particles can be observed, which is the proof of the unified theory of electroweakness.

LHC in Europe was able to reach the energy level of 10 ^ 13 electron volts, and the Higgs boson was discovered.

Xia Xia's collider consumed hundreds of billions of yuan of funds and once again raised the energy level to 10 ^ 15 electron volts.

and then?

No more, no new physics observed at 10 ^ 15 electron volts

But the "energy-level desert" conjectures that at the energy level of 10 ^ 24 electron volts, there will be no new physical phenomena. According to the current theory, if you want to continue to study high-energy physics, please increase the energy level by one billion times!

This is also the origin of the circumsolar accelerator, requiring an accelerator with a circumference of 100 billion kilometers to achieve this.

100 billion kilometers!

But that's not all about high-energy physics. For a 100 billion km accelerator, it is likely that only a combination of strong, electromagnetic, and weak forces will be observed. Gravity has not been wrapped in.

If you want to thoroughly study quantum gravity or the theory of all things in the legend, please build an accelerator with a length of 1000 light years, which is also known as the Galactic Accelerator!
