Voyage of the Stars

And what is negative mass? It is a characteristic of negative matter, just as matter has positive mass, negative matter has negative mass. Matter with negative mass is different from positive matter. They are not attracted by the gravitational field like antimatter and ordinary matter, but are repelled.

If there really is an object with negative mass, if you drop it on the earth, it will be repelled by gravity.

This is the minimal understanding of negative mass matter in the history of human scientific development, and negative mass also means negative energy. Beyond this, human science knows next to nothing about it.

What and how many kinds of matter are there with negative mass? What is its form of existence? How does it transform into negative energy? What kind of physical laws does it satisfy? Can it be observed?

There are a series of things that humans know nothing about.

So far, mankind has probably only stayed at the stage of conjecture about negative mass matter. But now the interstellar trading market has thrown out a negative mass generator. How can this not surprise mankind?

"Presumably this is the creation of the fourth-level civilization that they claimed to the kobolds, but they just don't know what it is used for." A scientist looked at the line of introduction, but did not find any description of the purpose of this negative mass generator.

Yue Yuan on the side heard the worry in his words. He also browsed through it and found no use.

At the beginning, Yue Yuan was also afraid that this thing was some kind of weapon, but after thinking about it secretly, he felt that it was unlikely.

First of all, although I have never seen the appearance of this negative mass generator, it does not look like a weapon. Instead, it looks like a piece of equipment with some function. Moreover, judging from its appearance and structure, it seems incomplete, because Yue Yuan discovered There are some structural connections.

Therefore, he had reason to guess that this negative mass generator was either a defective product or a core component of something.

If it's the latter, where does this thing come from?

Thinking of this, Yue Yuan pictured the warp engine in his mind, and at the same time glanced at Yu Nanfeng who was thinking.

Yue Yuan felt that this negative mass generator in the interstellar trading market must have had the same bad luck as humans, and it was picked up somewhere or from the ruins of an advanced civilization.

If so, that's great.

Next, everyone discussed and speculated about the negative mass generator, and then discussed it internally before sending a reply to the interstellar trading market.

"You are so unkind! Our earth civilization came across the galaxy not far away from us. We came with sincerity, but you sent such an unclear thing and said it was a high-end product. Oh, it is indeed a creation of an advanced civilization. , but I guess even you don’t know what it is. We don’t think it’s worth the value of a living planet for a creation whose function is unclear.

If there is nothing valuable in your interstellar trading market, our earth civilization believes that it is okay not to do this transaction. Of course, there is an old saying in our earth civilization that business cannot be done without benevolence and righteousness. If business cannot be done, we can also communicate in other aspects.

For example, we can set up a science and technology seminar specifically to exchange our development experience at the third-level civilization level, development routes, and unique science and technology prospects, etc. Our earth civilization is very eager for such exchanges and thinks it is very valuable. thing."

Human beings then made a lot of nonsense, and in summary they said that your interstellar trading market is too poor, and there is nothing worthy of a living planet.

Regarding human beings' response, the interstellar trading market has another explanation.

Not long after, a message representing the interstellar trading market was sent to humans.

[This is not what I said. Kind-hearted civilization on earth, if you understood advanced civilization, you would not say this. Do you know why advanced civilization can be called advanced civilization? 】

Since it is not real-time communication, the interstellar trading market's questions do not really require humans to answer before continuing. They just ask a question and then answer it themselves.

[We can tell you clearly that advanced civilizations have the ability to sail faster than the speed of light. Once the speed exceeds the speed of light, it will cause various problems, the most intuitive of which is communication.

If there is no communication capability that exceeds its own speed, then after becoming an advanced civilization, communication will be meaningless, because it is better to directly drive a spacecraft to send messages. On this point, the dictionary of your earthly civilization seems to have this sentence: Communication depends entirely on running. 】

Communication relies entirely on running, but communication relies entirely on roaring, okay?

Seeing this, everyone complained about the interstellar trading market in their hearts, and then looked down.

[That is unrealistic and inconvenient. All civilizations know that the hallmark of the fourth-level civilization is the realization of the grand unified theory and the application of this theory, but they often ignore another aspect, which is communication.

A Level 4 civilization must not only have the ability to sail beyond the speed of light, but also must have the ability to communicate over long distances before it can be called an advanced civilization. These two are like the two legs of a Level 4 civilization. If one of them is missing, it will not count. A true level four civilization. 】

[The negative mass generator we sent to you is the core component of ultra-distance communication. It is a complete creation. I won’t hide it from you, this is a special item that this trading market applied for from the Merchant Alliance.

To be honest, what we just sent you is only one percent of its parameters and description. It can be said that as long as you get it, it will be a matter of time for your earth civilization to be promoted to the fourth level civilization. Complete technical information It can help you quickly master the method of making long-distance communicators after reaching the fourth level of civilization. 】

[As for why we sell it, the reason is very simple. We are a member of the interstellar trading market. There is a fifth-level civilization behind us. Therefore, the technological advancement path of our trading market is different from that of ordinary cosmic civilizations.

As long as we have enough contribution points, we can exchange everything within the merchant alliance for the fourth-level civilization. This is why we are looking for people to do trade everywhere.

The Merchant Alliance needs many living planets for research, and interstellar trading markets like ours are the merchants of the Merchant Alliance. 】

After reading the reply from the Interstellar Trading Market, the humans discussed it for a while and then sent another reply letter.

"In that case, please send us all the information about the negative mass generator so that we can understand its value."

Regarding human beings' request, the interstellar trading market only said: [Yes, but we need the scientific research data on that planet that you have. Yes, it is the research data on that living planet by your earth civilization. 】
