Wandering Spaceship in Deep Space Chapter 80: Conjecture of “energy-level desert”

　　 So, Mars is not the focus of human attention on the planet, and there is only such a lonely space city above it, mostly in the nature of scientific research and transit stations.

　　 Martian enthusiasts are thinking about melting the two-stage carbon dioxide to improve the atmosphere of Mars in order to achieve the purpose of livability in the future.

　　"If the population explodes after human civilization, and the earth and the moon can no longer live, it will be possible to develop Mars...Compared with other planets, this planet is better for living people. Nothing has been found so far. Alien microbes are also safe." Senior Brother Zhao said suddenly.

　　 Zhang Yuan responded: "I think it seems that there is no such possibility in the foreseeable future. Because the growth rate of the civilized population is not high."

　　 Within the limits of natural resources, social systems, and productivity, the more the population, the better, especially the high-quality population.

　　 But capitalism is the contraceptive for population growth.

　　In the old age, limited by resource constraints, the population of the earth once stagnated at 7-8 billion for a long time.

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

　　 From the current population of tens of billions to hundreds of billions or even trillions, it’s actually very difficult. For many families, having a second child is already a very painful thing.

　　 As for the low-quality population in some countries, it is useless to have more.

　　 Zhang Yuan suddenly thought: "If in the future, artificial uterus technology and robot raising are developed, do you think this pattern will change?"

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

　　"...but I don’t think it can change the fundamentals of population growth. Because the most important thing for children is parenting, not the process of birth. Parenting consumes more energy than birth!"

　　"As for the raising of machines, how strong artificial intelligence is needed! Moreover, the ethics aspect may have to be discussed for a long time..."

　　" On the contrary, I am more worried about the uterine revolution strategy of some small countries. A large number of foreign immigrants will lead to a decline in the influence of the main nation. Conflicts between ideologies and cultures are likely to allow bad money to replace good money. History has This phenomenon has happened many times."

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

　　 just talked about the mountains like this, and visited the observatory for a while, Zhang Yuan suddenly discovered that there was an electronic reading room called "Xingchen Library" hidden here, and a few people were reading in it.

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

　　 After a random visit, the two of them turned around and returned to the rail car.

　　 The terminal of this journey is the tail of the mother ship, where the nuclear fusion engine is located.

　　 nuclear fusion engine, its largest ring diameter exceeds 400 meters. Just the tip of the iceberg is enough to make people feel shocked.

　　 When he witnessed this behemoth, Zhang Yuan felt his heart start to become hot.

　　The long-term work here, the joy and the sense of accomplishment, are definitely more intense than cleaning the cabin.

　　 On a recent test screen, a group of blue and white plasma is discharging, and changes in various parameters are also displayed nearby.

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

　　 "You are here!"

　　 "Professor Ding."

　　 Seeing a figure emerge from the room ahead, Zhang Yuan hurriedly said hello.

Academician 　　Ding is here to learn about the changes of various parameters, and happened to meet them.

　　"Zhang Yuan, it seems that you like it here. If you want to fully understand this big thing, you may have to learn some mechanics, nuclear physics, and plasma. There are a lot of things to learn."

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

　　"Let’s read some papers first. If you don’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, such as the heat value and cycle of the helium-cooled solid blanket. The impact of sexual shock on the cryogenic system helium turboexpander, etc. You can choose the subject 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 responded and found his seat.

　　 He fixed his body on the seat enthusiastically, trying to find some papers in the database.

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

　　 Of course, only reading permission, no modification permission.

　　 Zhang Yuan was very pleased to discover that in the entire nuclear fusion control project, a lot of work was done by his father, and the curiosity and eagerness in his heart would naturally be greater.

　　He thought to himself: "The work in nuclear fusion sounds like a lofty one. If you let Li Zhendong meet, I don’t know how long you can brag about..."

　　Nuclear physics, similar to high-energy physics, is a theory that studies the deep levels of the microcosm. Nuclear physics tends to be applied horizontally, while high-energy physics tends to be more microscopic and deep-level theories.

　　 But in this era, high-energy physics has gradually declined.

　　The main reason is that what can be found clearly has gradually been found out, and what is not understood is still not understood.

　　 In the 23rd century, Xia Guo Academy of Sciences used to spend a lot of money to build a larger collider, but the final result was that it could not knock out any particles that exceeded expectations. This project was reduced to a classic white elephant project. .

　　The standard model based on the non-Abelian gauge field seems to have become the supreme realm of human understanding of nature.

　　According to the estimates of some scientists, if you want to verify higher-level theories and find some physical phenomena beyond expectations, you need to build a ring solar system collider! That is to say ~IndoMTL.com~ The length of this collider has to circle the solar system once.

　　 is an impossible task for humans.

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

　　Matters in nature will have completely different properties under different accelerator energies.

　　 At an energy of 10 electron volts, one can observe that the atom disintegrates and decomposes into 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 electroweak.

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

　　 Xia Guo’s collider, which consumed hundreds of billions of funds, once again raised its energy level to 10^15 electron volts.

　　 Then what?

　　 There is no more, 10^15 electron volts, no new physics is observed

　　 But the "energy level desert" conjecture believes 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, which requires an accelerator with a circumference of 100 billion kilometers to do this.

　　 1,000 billion kilometers!

　　 But this is not all of high energy physics. An accelerator of 1,000 billion kilometers may only be able to observe the unity of strong force, electromagnetic force, and weak force, without gravitational force being wrapped in it.

　　 If you want to thoroughly study quantum gravity or the legendary theory of everything, please build an accelerator with a length of 1,000 light-years, that is, the ring galaxy accelerator!
