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

John woke up two months earlier than him, and seemed to be devastated by the bleak reality, so he just said hello to Zhang Yuan, and then sat in his seat all day long, stunned, not knowing what he was thinking.

Zhang Yuan let out a long sigh, almost everyone here is like this.

With the current social environment, it is impossible to do some complex work. At least half of the population is depressed, and it is quite rare to be able to do a simple job, so don't want to create much social value.

Fortunately, the decision-makers have anticipated this situation, and have also made certain arrangements when formulating the hibernation policy.

At present, there are a total of 600 sober people, of which more than 100 are responsible for the maintenance of the power system, and the rest of the population is distributed in communications, medical services, botanical gardens, material management and other aspects.

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

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

The Earth's engines are out, it sails through space by inertia, and most of its functions are turned off, so more than a hundred years of work will not accumulate catastrophic accidents, and it is okay for everyone to slack off a little.

……

In this uncomfortable atmosphere, time passed day after 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, historical, or humanities, there are many things worth learning seriously.

Because of the qualitative changes caused by quantitative changes, Zhang Yuan found that he couldn't even understand the most cutting-edge scientific and technological papers. He can only read some relevant news written by popular science websites to grasp the overall scientific dynamics.

He said to himself: "It's very good, it's a good thing if you can't understand it, if an ancient person like me can still understand it, the human race will definitely be finished." ”

"What happened to the ancients? It's okay for me to be a university teacher! John said, "In the 25th century, students in college are not studying calculus?" It's boring. ”

Zhang Yuan couldn't help but smile, this sentence is true, before the emergence of technology to improve the intelligence of the whole people, no matter what era college students should be learning calculus. The whole civilization still has to be driven by genius.

"John, what does this hyper-alpha mean?"

"I don't know, maybe it's a new academic term in condensed matter physics...... I'll help you look it up. ”

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

There was once a question on the Internet, if Einstein had traveled back in time to modern times, would he have become a top scientist?

It's not necessarily top-notch, but it's easy to become a good scientist again. Because under the influence of good habits, learning new knowledge is actually a relatively pleasant thing for Einstein, and it is estimated that he can learn cutting-edge subjects in a few years.

Even, when new knowledge is placed in front of you and not learned, there is a sense of depravity and uneasiness.

“…… Cutting-edge science is full of good news, through a condensed matter superfluid experiment, it seems that evidence of the existence of gravitons has been found! ”

Suddenly, Zhang Yuan seemed to have found some big news and shouted.

"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: cool!

According to the paper, scientists used superfluids to surround a limited area, and found that this part of the region has undergone very small gravitational changes.

This gravitational change exceeded expectations.

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

Evidence for the existence of gravitons is probably the greatest scientific discovery of the last two centuries!

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

There are many related papers, and there is still no winner to choose.

Seeing this, Zhang Yuan's heartbeat speed increased slightly, and he deeply knew how important the discovery of gravitons was to cutting-edge science!

"Gravitons are involved in physical phenomena that are gravity, and if gravity can be unified into quantum theory, then the "grand unified theory" will no longer be a dream! ”

"If, under the guidance of the theoretical foundation, anti-gravity and artificial gravity-related technologies can really appear, human beings will once again achieve a qualitative change in science and technology!"

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

Of course, for the current situation, he can only be a distant watchman and find some fun in these news.

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

"I'm already a two-hundred-year-old elder, juniors, come on." Because he was in a good mood, Zhang Yuan joked.

"Ahem, if you want to understand the civilization of the earth, you can take a look at the special report of the Deep Space Foundation every year, instead of looking for information here, there are so many outrageous news sent by various sources, and some of them are fabricated by the media."

John said slowly.

After so many months, he has slowly returned to normal. Moreover, Zhang Yuan's liver-bursting learning spirit also directly drove him, so that he had to follow suit.

This guy still sighs sometimes, but he can finally communicate.

I have to say that time can dilute everything, and human beings are also very receptive creatures, and if they choose to keep themselves busy, all the heaviness will be slowly thrown behind......

People always have to live for themselves.

"Why, seeing these scientific research results, you are not pessimistic about the future of the earth's civilization?" Zhang Yuan asked with a smile: "It's still refreshing to see scientific progress, once the science and technology of the earth's civilization undergoes a qualitative change, we will also undergo a qualitative change."

John excitedly said, "What a great discovery it is! I was also happy for a long time the other day, diluting that pessimistic expectation. By the way, what do you think about the gravitational loss phenomenon caused by the phenomenon of superflow? How to industrialize anti-gravity? ”

"Gravitons and fermions have an interaction, and in addition to the Yukawa coupling, which resembles the interaction of electrons and photons, there may be other terms in the Rallais quantity. I think that as long as these terms are figured out, the effect of gravitational shielding can continue to increase! ”

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

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

"Don't be too optimistic, at the moment, the whole theory is not completely clear."

The more the two of them talked, the more excited they became, and they began to talk about the mountains indiscriminately, as if anti-gravity technology could really be achieved......
