In his office, Zhang Yuan met an old acquaintance, Mr. John Wilson, the pessimistic scientist in the nuclear fusion engine.

John woke up two months earlier than he did. It seemed that he was devastated by the bleak reality. He just said hello to Zhang Yuan, and then sat in his seat all day. He was in a daze and didn't know what he was thinking.

Zhang Yuan sighed. Almost everyone here is like this.

In the current social environment, it is impossible to engage in some complicated work. At least half of the population is demoralized. It's quite hard to do a simple job. Don't try to create too much social value.

Fortunately, the decision-making level has estimated this situation in advance, and has made certain deployment when formulating hibernation policy.

At present, there are 600 people in total, and more than 100 people are responsible for the maintenance of the power system. The rest of the population is distributed in communication, medical, botanical garden, material management and other aspects.

There are also a small number of soldiers and administrative personnel responsible for maintaining law and order.

In this small self-sufficient society, everyone's workload is very small.

The engine of the earth age is in a state of extinction, and it is sailing in the universe by inertia. In addition, most of its functions have been turned off, so it is not likely to accumulate catastrophic accidents in more than 100 years. It's OK for us to slack off a little.

……

In this uncomfortable atmosphere, time passes day by day. Zhang Yuan has restrained all his emotions and began to learn new knowledge normally.

There are enough new things happening on the earth. Whether it is academic, historical or humanistic, there are many things worth learning.

Because of the qualitative change caused by quantitative change, Zhang Yuan found that he could not even understand the most cutting-edge scientific papers. He can only look at the relevant news written by some popular science websites to grasp the overall scientific trends.

He said to himself, "it's very good. It's a good thing not to understand. If ancient people like me can still understand it, human beings are doomed."

"What happened to the ancients? I'm going to be a university teacher, so it's OK! " John said: "in the 25th Century, aren't college students still learning calculus? It's boring. "

Zhang Yuan couldn't help laughing. This is true. Before the emergence of the technology to improve the intelligence of the whole people, college students in any era should be learning calculus. The whole civilization is still driven by genius.

"John, what does this super alpha state mean?"

"I don't know. Maybe it's a new academic term in Condensed Matter Physics I'll check the papers for you. "

In the face of modern knowledge, the two people in the office don't understand a lot. However, it's interesting to study with many people. The research progress is faster than that of one person.

Once upon a time, there was such a question on the Internet. If Einstein went through modern times, could he become a top scientist?

The top is not necessarily, but it's quite easy to be a good scientist again. Because under the influence of good habits, learning new knowledge is actually a relatively pleasant thing for Einstein. It is estimated that he will be able to learn cutting-edge subjects after a few years.

Even if you don't learn when you have new knowledge in front of you, you will feel a sense of degeneration.

“…… Good news for frontier science. It seems that evidence of the existence of gravitons has been found through a condensed state superfluid experiment! "

All of a sudden, Zhang Yuan seems to have found some big news and yelled.

"It's not easy!"

After reading one of the papers, he sighed deeply.

The mood at the moment can only be described in one word: cool!

According to the description of this paper, scientists use superfluid to surround a limited region, and find that there is a very small amount of gravitational change in this region.

This gravitational shift is more than expected.

In some theories, the graviton is a spin-2 boson, which produces a superfluid mechanism similar to that of helium-4. In other words, this part of the superfluid is likely to short circuit some of the gravitons flowing through this region, so as to achieve local shielding.

The evidence for the existence of gravitons is probably the greatest scientific discovery in the last two centuries!

It means that some basic theories seem to be able to be further developed.

A variety of related papers emerge in endlessly, up to now there is no final winner.

Seeing this, Zhang Yuan's heart beat a little faster. He deeply knows how important the discovery of gravitons is to frontier science!

"Graviton involves physical phenomenon, that is, gravitation. If gravitation can be unified into quantum theory, then" grand unified theory "will no longer be a dream!"

"If, under the guidance of theoretical basis, anti gravity and artificial gravity related technologies can really emerge, human beings will once again realize the qualitative change of science and technology!"

Zhang Yuan is very willing to engage in this research.

Of course, for him at present, he can only be a distant spectator, looking for some fun in these news.Any progress of human civilization is a very safe and gratifying thing for him.

"I'm already 200 years old. Younger generation, come on." Because I'm in a good mood, Zhang Yuan joked.

"Cough, if you want to understand the earth civilization, you can look at the special reports of the deep space foundation every year instead of looking for information here. There are so many fantastic news, some of which are fabricated by we media."

John said slowly.

After so many months, he has gradually returned to normal. What's more, Zhang Yuan's explosive learning spirit also directly led him to learn along with him.

This guy still sighs sometimes, but at least he can communicate.

It has to be said that time can dilute everything, and human beings are also creatures with strong acceptance ability. If we choose to keep ourselves busy, all the heaviness will be slowly thrown behind us

People always have to live for themselves.

"Why, seeing these scientific research achievements, you are not pessimistic about the future of earth civilization?" Zhang Yuan asked with a smile: "it's very refreshing to see scientific progress. Once the science and technology of the earth civilization changes qualitatively, we will also change qualitatively"

John said excitedly: "it's really a great discovery! A few days ago, I was also happy for a long time, diluting the pessimistic expectation. By the way, what do you think of the gravitational loss caused by superfluidity? How to realize anti gravity industrialization? "

"There is an interaction between the graviton and fermion. Besides the Tokugawa coupling, which is similar to the electron photon interaction, there may be other terms in the Lagrangian. I think as long as we understand these terms, the gravitational shielding effect will continue to increase! "

"The nature of the world is really beyond imagination!"

"Aren't the four basic forces the ultimate essence?"

"Don't be too optimistic. At present, the whole theory has not been thoroughly clarified."

The more they talked, the more excited they were, and they began to talk wildly, as if anti gravity technology could really be realized
