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

John woke up two months earlier than him, and seemed to be damaged by the bleak reality. He just greeted Zhang Yuan, and then sat in his seat all day long, dazed in a daze, not knowing what he was thinking.

Zhang Yuan sighed, almost everyone here is like this.

With the current social environment, it is unlikely to engage in some complex jobs. At least half of the population is depressed, and it is rare to be able to do a simple job. Don’t think of creating too much social value.

Fortunately, the decision-makers have estimated this situation in advance and have made certain allocations when formulating hibernation policies.

Currently, there are a total of 600 people who are sober, and more than 100 people are responsible for the maintenance of the power system. The remaining population is distributed in communications, medical care, botanical gardens, material management and other aspects.

There are also a few soldiers and administrative personnel responsible for maintaining public order.

In this small self-sufficiency society, everyone has a very small workload.

The Earth Age engine is in an extinguished state, and it is sailing in the universe by inertia, and most functions have been turned off, so more than a hundred years of effort will not accumulate catastrophic accidents. It would be fine if everyone is a little lazy.

...

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

There are enough new things happening on the earth, whether it is academic, history, or humanities, there are many things worth studying seriously.

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 could only read related news written on some popular science websites to grasp the overall scientific dynamics.

He said to himself: "It's very good. It's a good thing to not understand. If ancient people like me still understand it, humans will definitely be finished."

"What happened to ancient people? I'll be fine if I'm going to be a university teacher!" John said: "It's the 25th century, aren't college students still studying calculus? It's so boring."

Zhang Yuan couldn't help but smile. This sentence is true. Before the emergence of the technology of the whole nation to improve its intelligence, college students in any era should be learning calculus. The entire civilization still needs to be promoted by genius.

"John, what does this superalpha state mean?"

"I don't know, it may be a new academic term in condensed matter physics... I'll help you check the relevant papers."

The two people in the office have a lot of things they don’t understand when facing modern knowledge. However, it is actually quite interesting to study together by multiple people, and the research progress is faster than that of one person.

There was once a question on the Internet: If Einstein traveled to modern times, could he still become a top scientist?

It is not necessarily the top, but it is still quite easy to become an excellent scientist again. Because under the influence of good habits, learning new knowledge is actually a relatively pleasant thing for Einstein. It takes a few years to learn cutting-edge subjects.

Even if you have new knowledge in front of you but don’t learn it, you will feel a sense of depravity.

"...There are good news in cutting-edge science. Through a condensed matter superfluid experiment, it seems that evidence of the existence of gravitons has been found!"

Zhang Yuan suddenly seemed to have found some big news and started screaming.

"It's really not easy!"

After reading one of the papers, he sighed deeply.

The mood at this moment can only be described in one word: it’s cool!

According to the description of this paper, after using superfluid to surround a limited area, scientists found that a very small amount of gravitational changes occurred in this part of the area.

This gravitational change exceeded expectations.

In some theories, gravitons are bosons with spin 2, which will produce a superfluid mechanism similar to helium-4. That is, this part of the superfluid is likely to short-circuit some gravitons flowing through this area, thereby achieving localized shielding.

Evidence about the existence of gravitons may be the greatest scientific discovery in the past two centuries!

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

Various related papers have emerged one after another, and the final winner has not been chosen yet.

Seeing this, Zhang Yuan's heartbeat speed slightly accelerated. He deeply knew how important the discovery of gravitons is to cutting-edge science!

"Gratonics involve physical phenomena, which is gravity. If gravity can be unified into quantum theory, then the "great unified theory" will no longer be a dream!"

"If anti-gravity and artificial gravity-related technologies can truly appear under the guidance of theoretical foundations, human beings will once again achieve qualitative changes in technology!"

Zhang Yuan is still very willing to engage in research in this area.

Of course, for him at present, he can only be a distant viewer and find some fun in these news.

Any progress in human civilization is a very safe and gratifying thing for him.

"I am already a two hundred-year-old elder. Come on, juniors." Zhang Yuan joked because he was in a good mood.

"Ahem, if you want to understand the earth's civilization, you can check out the annual special report of the Deep Space Foundation, instead of randomly searching for information here. There are so many outrageous news sent here, and some of them are randomly fabricated by self-media."

John said slowly.

After so many months, he has slowly returned to normal. Moreover, Zhang Yuan's spirit of learning that has exploded directly led him, making him have to learn with him.

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

I have to say that time can dilute everything, and humans are also a creature with strong acceptance ability. If you choose to keep yourself busy, all the heaviness will be slowly thrown behind your head...

People always have to live for themselves.

"Why, seeing these scientific research results, are you no longer pessimistic about the future of Earth civilization?" Zhang Yuan asked with a smile: "It's still very refreshing to see scientific progress. Once the technology of Earth civilization changes qualitatively, we will also undergo qualitative changes."

John said excitedly: "It's indeed an amazing discovery! I was happy for a long time a few days ago, diluting that pessimistic expectation. By the way, what do you think about the loss of gravity caused by the superfluid phenomenon? How to industrialize the anti-gravity?"

"Gratonics and fermions have an interaction. In addition to Yukawa coupling similar to the action of electron photons, there may be other terms in the Rashima quantity. I think as long as you understand these terms, the effect of gravity shielding can continue to increase!"

"The essence 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 understood."
