It is also true that on the scale of quantum mechanics, there are virtual particles in the universe. When light from the distant universe passes through long distances, space-time foam caused by virtual particles will interfere, which is a technical bottleneck in astronomical telescope observations.

As far as planetary telescopes are concerned, the resolution has reached its limit, and it is difficult for even larger telescopes to capture things in more distant areas.

This is similar to the highest resolution of an optical microscope of 200 nanometers, except that one is very large and the other is very small.

There is also gravitational-wave telescope technology, which can break through the technical bottleneck of optical telescopes. But this kind of telescope is extremely difficult technically, it is an advanced technology in a fourth-level civilization, and the price of renting this thing is simply outrageous!

Between cost performance, people have to choose carefully.

Cocoa Silk Wart finally said: "If your civilization really wants to get information about something, you can buy it directly from us, and the information relay stations of amoeba civilizations are all over the galaxy!" Of course, the price of a valuable message may be a little more expensive than renting a telescope, but we guarantee the authenticity of the information! Without this information, we would never have faked! ”

Seeing this internal information, Zhang Yuan couldn't help but shake his head, feeling that these big insects were really good at doing business, and they could sell anything, including this kind of planetary fortress that could actually be rented.

"In this way, as long as you have enough amoeba points, with the help of the amoeba civilization, it is not too much of a problem to become a fifth-level civilization......

"However, even the Huantai civilization itself does not have so many amoeba points......"

In the past few years, he has stayed in the mothership, and has not personally visited the trading market, but has just immersed himself in hard study, and learned about the general dynamics of the entire civilization through these internal materials.

"What do you think our diplomats will choose? It is expensive to buy this kind of message directly, but our scientists have determined that there is no astronomical structure in a radius of 200 light years. ”

"If you can't find this star structure at 300 light-years or 400 light-years, it's a great tragedy......"

"But why do I think this tragedy is going to happen?"

Zhang Yuan turned around and asked Ms. Kate, a colleague around him.

The current spacecraft of mankind can only reach 12% of the speed of light at most near the cosmic string, which is the maximum speed that can ensure the safety of the fleet, not including the rectification and maintenance once every hundred years in the middle. Under this kind of sub-light sailing, it is not possible to do without maintenance.

But this speed is as slow as a snail in the universe! Traveling at 12% of the speed of light to hundreds or thousands of light-years away is too much effort.

Kate shook her head: "No way, this astral structure is a minority after all, we can only pray that this kind of tragedy does not happen." ”

Zhang Yuan sighed softly, thousands of light years apart, there is not much point in observing the collision of neutron stars, how to find the neutron star that is about to collide, and run over to observe it up close, has become a big problem for the new human civilization.

As representatives of the Institute, they are preparing to attend the latest meeting of the Scientific Council.

For such a long time, Zhang Yuan has become familiar with his new colleagues, which is a very young and motivated group. The learning atmosphere in the institute is very good, and Zhang Yuan likes it quite much.

Of course...... In just six years, the research results in extradimensional perception are very small, but it cannot be said that there are none, it can only be said that it is slow progress. It is not easy to take any step forward in this kind of abstract learning, and the first thing to lay is some theoretical things.

"I think it's also a good choice to buy messages directly!" Kate thought for a moment, "Since our telescope has been searching for six years and has not found a suitable neutron star, it is better to buy this information directly...... At least that's what I think. ”

"Of course, I will not blindly initiate a vote, and the content of this should be judged by the diplomats."

Zhang Yuan nodded, astronomers have been under a lot of pressure over the years, so they naturally have their own thoughts, and they don't need outsiders to point out indiscriminately.

In the midst of this chat, everyone entered the venue, found their seats, and sat quietly.

Mr. Captain walked to the podium and began to report on the achievements of the sixth year: "Ladies and gentlemen, today is the sixth year that we have come to the Huantai Civilization Trading Market, and it is necessary to let everyone know the overall trend of the entire civilization, and we also need to judge some major choices......

In the past six years, the actual industrial capacity of the entire fleet has not increased, but has declined to a certain extent. The main reason is that in the trading market, resource replenishment has to pay amoeba points.

Although the resources here are cheap, really cheap. But poor human beings are still a dime, and in this respect they are like iron roosters, saving as much as they can.

On the other hand, there are always some restrictions in the trading market, and there is no need for people to engage in industry under the noses of other civilizations.

But from the academic side, there is so much progress!

Thanks to these years of foreign trade and various academic exchanges, mathematicians, physicists, materials scientists, and subatomic scientists have taken the stage to speak one after another, reporting on the work made in recent years.

Listening to their reports, the audience burst into applause.

Ms. Kate whispered beside her, "Isn't it envious? Our institute doesn't have a lot of achievements, so there's no way to speak on stage. Your former subatomic engine research institute has made remarkable achievements, and if you put it in the past, you would have been the one who spoke on stage! ”

Zhang Yuan said with a smile: "Envy? What's the use of envy, we have to work harder! If we make achievements in this work, it is related to the IQ of all mankind, and we can instantly compare all the achievements of others and make them stare at each other! ”

Kate couldn't help laughing, "But it didn't make any results...... It is estimated that there will be no results in a few decades, don't you regret it? ”

Zhang Yuan continued: "I don't regret it, I just hope that more and more people can come to power like this...... These are very beautiful results, and they are remarkable. ”

"If one day in a given year, no one will come on stage to publish their research results. In other words, it is the result of some crooked melons and cracked dates, but we are still applauding and cheering, then it means that our civilization has stopped making progress and entered a recession. ”

"That's right." Kate suddenly seemed to remember something, "By the way, I have a special message for you." ”

"What's the news?"

"On the topic of the return of the Transcendent...... The next five days of the meeting will discuss decisions regarding the return of the Transcendent. There are many people who believe that this opening should be opened up a little bit, so that more excellent talents can return. Our civilization is about to enter a turning point, and we need more high-quality talents. ”

"I'd like to hear from you."

Zhang Yuan said: "I also heard about it. Of course, I think this aspect should be strictly controlled...... The standard can be lowered, but not too much. ”

Kate asked a little gossipily, "If you were a little more relaxed, maybe your former wife would have returned?" You're not saying that in the virtual world of the past, you never got married and had children. ”

Zhang Yuan said with a smile: "I haven't been married and have children, because I am busy with my own career, and I really don't have the mind to do this!" These virtual worlds, compared to our current society, are so unbeautiful that they have fought all their lives for the happiness of all mankind and died young. ”

Not only Kate, but several colleagues around him laughed, these are all personal privacy, unless Zhang Yuan himself is willing to say it, it is impossible to get it with the permission of an ordinary researcher alone.

Zhang Yuan continued: "If my wife can return, of course it will be a good result. But I still won't relax the criteria for this, and I believe that other returnees will make the same choice......"
