"The star domains far away from the hyperspace channel, high-level literature rarely get close to them, but it is equally difficult for us to get to the depths of these star domains."

Fang Yuan shrugged and added what he had said before.

"Yes. The distance between the spiral arms of the Milky Way is generally more than 5,000 light-years. If there is no hyperspace channel, it will take 500 years to develop the second home when the Galaxy spiral arms next to it. It will take 500 years to fly to the end with ten times the speed of light." Lang Tongguang sighed.

500 years, in the cosmic scale, is not actually long.

However, for a person, it is a length of time that cannot be crossed in his entire life.

"In fact, there is another more critical question. Whether a star system has hyperspace nodes needs to be explored before confirming. It is not that there is no one on the star map now. After all, the star map we master only accounts for 0.04% of the Milky Way." Chu Xingyun added.

"The star map we have now is too old. Is it possible to get the latest star map from the Carbon-based Alliance?" Lang Tongguang looked at the department responsible for communication with alien civilizations in the Supreme Council.

"We have tried it. The Piggs, the photosynthetic civilization, said that the star map given to us is indeed the star map from 20,000 years ago. The latest star map is a military secret. It is impossible to give it to us, and it cannot even be traded." Hu Haitong, head of the communication department of the alien civilization, replied.

"Even if there is no newer star map, is it possible to get it?" Lang Tongguang asked.

"Pigges' reply was that the star map 3,000 years ago was tradable content." Hu Haitong replied.

This answer immediately aroused everyone's interest.

“Since you can trade, when can you complete the transaction?”

"This... According to Piggs' description, we do not have the higher civilization currency required by the Carbon-based Alliance. Therefore, it is impossible to achieve transactions. At the same time, the number of stars recorded in the 3,000-year star chart is 100 million, which is more than 80 million, and the number of more is limited. Therefore, the transaction value is still to be discussed." Hu Haitong spread his hands and expressed helplessness.

"What is higher civilization currency?" Fang Yuan is more concerned about this issue.

"A substance called Zro, Zro is transliterated, and the Chinese character is transliterated as 'Zero'. We do not know what this substance is, we can only transliterate it. Information about Zro? Has been submitted to the Academy of Military Sciences? Our department only knows so much about this substance." Hu Haitong spread his hands again.

Information about this unknown substance? A department in charge of diplomacy really can't know more.

General Rhodes looked over to the Academy of Military Sciences and asked, "Has the report on this substance been released?"

"There is already a preliminary report? But it cannot answer what Zro is. Yesterday, he heard from the Curvature Technology Laboratory. Professor Yang Yuping took over the analysis of this information? The news in the morning said that I could come up with a prepared report today." A representative of the Military Academy gave a reply.

At this time.

A communications intervened in the venue. After confirmation, an image of a person appeared on the big screen, which was exactly Yang Yuping.

However, the image that appears on the screen is not a robot image, but a real person image.

It is obvious that what is displayed on the screen is a video of Yang Yuping's previous one.

Fang Yuan knows why Yang Yuping did not reveal the appearance of the robot, because the carbon-based life soul energy is energetic? There is controversy in terms of morality and human ethics.

To avoid unnecessary trouble, confidentiality is required.

Yang Yuping began to give a report: "About Zro, our team already knows what that is. The complex verification process is omitted, and in words that everyone can understand? This is a higher purity star source aerosol.

“Of course, the reality is not that simple.

"This Zro is a state of aerosol? It is very light in mass? It can float in the air.

"Theoretically? It can be purified from star source ore.

"However, according to the data provided by the photosynthetic civilization, the Zro concentration of the star source ore we currently mine has not reached the purified concentration.

"To put it simply, humans are not able to mine now and purify them to obtain Zro."

"Star source aerosol? Why can't it be purified? Is it too technically difficult?" General Rhode asked.

"Technology is one side, and on the other hand, the Zro concentration of the star source mine is too low. In fact, we cannot even detect Zro from the star source mine. All the conclusions are analyzed from the data provided by the photosynthetic civilization." Yang Yu spread his hands and expressed helplessness.

"What exactly is Zro? Is dark matter?" Fang Yuan frowned and asked.

Dark matter is actually a general term for unobservable matter.

Dark matter is actually not a kind of matter, it may be many kinds of matter, but its characteristic is that humans cannot observe it in any way.

Once a certain dark matter is observed by humans through technological means, then this matter has been picked out from the category of dark matter.

"Not just dark matter, I would rather call it materialized energy. From the data, it can be seen that Zro can convert all mass into energy, and the conversion ratio meets the mass-energy formula E=mc^2." Yang Yuping gave a very amazing answer.

All scientists know a scientific truth, when science reaches its end, mass equals energy.

In fact.

There is no need to wait until science reaches its end, and humans have already seen the law of the universe that mass equals energy.

That's right, that's antimatter.

Antimatter annihilation completely complies with the rule that mass equals energy.

The amount of antimatter of the mass can generate as much energy as possible.

The sum of energy generated is equal to the total mass of positive and negative matter.

So, humans have mastered antimatter technology and are also converted into energy in full mass. Is Zro still important?

The answer is, of course it matters.

Judging from the fact that Zro is a high-purity star source aerosol, Zro should be a mild energy source.

A mild energy has a value that is countless times higher than a strong energy source.

Just a little comparison will tell.

The gap between nuclear fusion and controllable nuclear fusion is a world of difference.

However, controlled nuclear fusion cannot be called a mild energy source.

It is conceivable how big the value gap is between mild energy.

From this point of view, it is not surprising that Zro has become a currency of higher civilizations.

"In fact, the first purpose of higher civilizations occupying so many stars is stellar energy, and the second purpose is to find the mineable Zro. Therefore, Zro has become a hard currency for higher civilizations. We do not have the ability to mine such things now, and we cannot even detect them by detection." Yang Yuping's tone revealed a hint of helplessness, and at the same time, it also implies infinite yearning.
