This red light curtain is not far from Xiao Yu, and after measurement, this light curtain is about 10 billion kilometers away from this star. Moreover, Xiao Yu found that this light curtain was shrinking inward at a speed of about 1.6 kilometers per second.

"At this rate of shrinkage, it will indeed reach its minimum point in about two hundred years, but don't forget, this is a red giant...... Its diameter itself has reached 60 million kilometers, even with my current spaceship performance, it can only survive 20 million kilometers away at most, and if it gets closer, it will not be able to come back, so if it is calculated like this, I still have ...... One hundred and ninety-six years. ”

"Let's check on this barrier first." Xiao Yu pondered, manipulating the huge fleet and slowly moving forward.

After traveling to a distance of two billion kilometers from the central star, the Hebei led a large group to a halt, and a city-level spacecraft took on the task of exploring the flagship of the fleet, leading hundreds of small ships to continue to advance.

The view is magical. Xiao Yu knew the shape of this barrier, it was oval, and it enclosed the entire galaxy inside. However, because it is so large, its curvature is not even perceptible on a smaller scale. That is, if you look at it from a single location, it is flat.

It's as if you look up at the sky and the whole sky turns a faint red. Under this red block, no stars can be seen.

Within this huge sphere with a radius of up to 10 billion kilometers, only Xiao Yu's fleet and the huge star in the center remained, and there was nothing else.

This is an interstellar prison, and Xiao Yu has become the only prisoner in this prison.

The Langfang is moving forward with many precision instruments. It will carry out a survey of the barrier. Obtain some jishu parameters for Xiao Yu to carry out future research.

After a day's journey, the Langfang reached its destination. At this moment, the Langfang is still less than 300 kilometers away from this barrier, and is following this barrier, shrinking inward at a speed of 1.6 kilometers per second. In this way, the Langfang and this barrier remain relatively stationary, and can carry out research steadily.

Several village-level ships slowly approached the barrier.

Xiao Yu made a penetration attempt first. One of the village-level spaceships slammed directly into the light curtain. When this village-level ship crashed past. The Langfang kept a close eye on it. There are many precision optical instruments being filmed.

But something that surprised Xiao Yu happened.

Xiao Yu saw that after touching this barrier, the head of this village-level spaceship disappeared directly. However, although the spaceship has disappeared, the communication between Xiao Yu and this village-level spaceship is still maintained.

Xiao Yu immediately commanded the village-level spacecraft to send out a broadcast in order to locate it for the satellites near it. Xiao Yu was surprised to find. This village-level spaceship was unknowingly. From a place of 10 billion kilometers from the central star. Ran to a place only a billion kilometers away from the central star.

In this instant, the village-level spacecraft crossed a distance of nearly nine billion kilometers.

"Does that mean that anything that comes into contact with this barrier will be teleported to another location?" Xiao Yu thought about it, manipulated another village-level spaceship, and tried again.

As a result, it was. This village-level spacecraft, after coming into contact with this barrier, still disappeared without warning, passing through the satellite positioning system. Xiao Yu found it in another place, 1.3 billion kilometers away from the central star.

"Teleportation is random?" Xiao Yu speculated and continued the experiment.

The result is still the same. Any ship that comes into contact with this barrier is randomly teleported to a random point between a billion and 1.1 billion kilometers from the central star.

"It seems that what Taihao said to me is true." Xiao Yu thought, "This barrier is really insurmountable. ”

After the spacecraft came into contact with Shiyan, it was an inspection of the visible light band.

This barrier would emit a faint red light, and Xiao Yu tried to find some specific information about this barrier from these red lights.

However, the optical spectrum analyzer showed that the light of the red light was the same as that of the central star.

At very high energy levels, such as the surface of a star, different elements emit different rays of light. Through spectroscopic analysis, the elemental composition of a star can be determined.

For example, in the age of the earth, through spectral analysis, human beings can even analyze the elemental composition of distant stars billions of light-years away.

Xiao Yu had already conducted spectral analysis of the central star and had mastered its data for a long time. But the light of this barrier would actually be the same as the central star, which really surprised Xiao Yu.

"Perhaps...... Is the light emitted by this barrier itself the light of the central star reflected? Xiao Yu guessed and began to analyze the spectrum of the ultraviolet and infrared bands.

The results of the analysis are still the same as those of the central star.

It seems that this barrier is a huge mirror that reflects back all the light that hits it, visible or invisible.

But it's clear that it can't be as simple as a mirror.

In this regard, Xiao Yu made his own guess.

Perhaps, this is the wonder of the four-dimensional fragment, which is not a mirror, but has some of the physical characteristics of a mirror. Its fourth dimension may be curved for the three-dimensional shijie, and when the light touches it, it will enter the four-dimensional shijie from the three-dimensional shijie, and then through the bending of the fourth dimension, it will return from the original way. ”

"My spaceship may also be based on this principle, but the details are different, resulting in my spaceship being randomly teleported to the inner galaxy instead of returning the same way."

It seems that Taihao is not lying. Sure enough, all the information could not be transmitted. The star, and the 10 billion kilometers of space around it, are separated. ”

"No, that's not right!" At this time, Xiao Yu suddenly realized the contradiction.

"The light will be reflected back, does that mean that the heat of the star cannot be transmitted? This violates the most basic laws of physics. ”

The star's heat cannot be transferred, which means that if the temperature on the inside of the barrier is three degrees, and the temperature on the outside of the barrier is two degrees, one high and one low, then the laws of physics require that the heat must be conducted from the high to the low. However, since the temperature cannot be transmitted due to the existence of the barrier, how can they achieve heat conduction?

This phenomenon is like a kettle that can completely isolate the loss of heat and keep the hot water in the kettle warm forever. The most basic scientific literacy told Xiao Yu that this phenomenon could not happen.

This is the entropy increase theory. Within a system, entropy can only increase over time, not decrease, or remain the same. It is impossible to stop the increase in entropy without having the rest of the effects.

Obviously, if there is really no heat transfer around the barrier, then the entropy increase theory is broken.

If this phenomenon really exists, Xiao Yu's theoretical cornerstone should be completely overturned and restarted.

"There is only one explanation that can take into account the contradiction between my theory and the current phenomenon." Xiao Yu thought silently, "The only possibility is that this star and the surrounding space have been separated from the three-dimensional shijie where I was originally located. They belong to two different systems. Since they are not in the same system, then the entropy will not continue to increase. ”

This conclusion made Xiao Yu feel a little palpitation.

"This situation is a bit similar to the Xiaoqian Shijie ...... mentioned in some fantasy novels" Xiao Yu came to a conclusion that made him a little crying and laughing.

"There is a good chance that this is the case. My theory, generous xiangshang should be correct. Otherwise, I would not have been able to achieve so much in a false theoretical system. But right now, phenomena that go against my perception are actually happening. My explanation is the only one that can do both, so it should be correct as well. ”

Xiao Yu came to a conclusion.

"But there's another question, I wonder what the situation here will be from the outside world?"

"Since the light and heat cannot be transferred, from the outside world, it should be that this star has suddenly disappeared from the universe."

Obviously, a star doesn't disappear for no reason. If a star disappears for no reason, I don't know how many civilizations will peep at.

"Tai Hao said that this barrier will keep me absolutely safe from the prying eyes of any eyes, it seems that I should be suspicious of this passage. After all, it is a star, and its disappearance cannot fail to attract the attention of the rest of existence. The Sweeper civilization is hundreds of light-years away from me, even if other civilizations will not dare to come over because of the presence of the Sweeper, but what about the Sweeper? What if it came to investigate? Taihao's four-dimensional structure was directly shattered by the Neutron Battle Star, and I don't think this barrier can stop the exploration of the Sweeper civilization. ”

After thinking of this, Xiao Yu was inexplicably worried in his heart.

"I don't know if this is Taihao's negligence, or if Taihao has other arrangements. Hey, even if Taihao is kind to me, this feeling of being manipulated by others is still a little bad. But...... At this time, it is useless to think about these things, I still honestly develop my own technology, and do my best to obey the destiny of God. If it is found by the sweepers, it is also my bad luck and there is nothing I can do. ”

After figuring this out, Xiao Yu let go of his psychological burden, took his attention back from this barrier, and began to study his own technology system. (To be continued......)
