"Black hole?" Su Yichen first felt that this was a black hole, because in this airspace, the space was twisting in a strange way, and some matter kept rushing towards the center of the airspace. It was like a vortex in a pond. Things thrown into the edge of the vortex will be attracted by the vortex and thus pulled into the inside of the vortex.

But when the idea of ​​a black hole flashed through his mind, Su Yichen immediately denied it. During the space navigation, Su Yichen had seen black holes, especially on Ike's spaceship, they experienced a long journey from the Milky Way to the Andromeda Galaxy, and they discovered many black holes in the universe along the way.

A black hole is a strange celestial phenomenon. When a star reaches the end of its life, the matter of the star will continue to collapse and compress, and attract a large amount of matter in the surrounding space, and eventually become a special celestial body with infinitesimal and infinitesimal size. When this matter is formed, the black hole will be produced accordingly. In fact, a black hole is a special celestial phenomenon on the periphery of this special matter. It has great attraction. According to theory, this gravity can almost be so large that even light cannot escape.

In the 20th century, Earth scientists proposed the theory of black holes. For ordinary people, black holes are extremely terrible, but in fact, when they directly enter the gravitational range of black holes during space navigation, the consequences are of course very serious.

But in fact, when sailing in the universe, special celestial bodies such as black holes are not as terrible as imagined. It is true that black holes have great gravity and can pull all objects that pass through their gravitational range. But in fact, although there are many black holes in the universe, it is impossible to become intelligent life of cosmic civilization to fly directly towards the black hole. Due to the particularity of black holes, it is easy to be discovered in the universe in advance. As long as the gravitational range of black holes is avoided, black holes are not terrible.

However, the black hole that appeared in the airspace in front is a certain difference from the black hole that Su Yichen imagined, because he could actually see the light floating on the edge of the celestial body. It was these lights that made Su Yichen instantly deny that it was a black hole. You must know that the black hole's gravity is so powerful that it cannot escape even light. If this is really a black hole, then they cannot see the light.

So, what is this if this is not a black hole? Su Yichen looked at this strange celestial body. Another familiar celestial body state flashed through his mind, that is, the wormhole.

Wormholes are a more special celestial phenomenon in the universe than black holes. In a popular way, wormholes are a channel connecting space and space. Su Yichen and others are familiar with wormholes. They accidentally fell into the wormhole and came to the Andromeda Galaxy. Later, they returned to the Milky Way through the artificial wormhole opened by the Rand civilization.

Although there is a difference between the two wormholes, the former is naturally produced, while the latter is created by the Rand civilization by powerful technology. However, wormholes are wormholes, and their essence will not change. Moreover, there is a huge difference between wormholes and black holes. Although the two seem somewhat imaginative on the surface, it is still easy to distinguish.

As expected, Su Wei carefully scanned this celestial body. Not long after, the results of the scanning were confirmed, and the results were indeed as Su Yichen thought. This is a wormhole.

"I didn't expect we would meet a wormhole." Looking at the wormhole in the distance, Su Yichen couldn't help but sigh. In the universe, the appearance of wormholes is extremely accidental, and its number is much smaller than that of black holes. More importantly, the generation of wormholes has special factors, and it does not exist for a long time like black holes. Sometimes the appearance and disappearance of some wormholes are only a short period of time, such as the wormhole they fell into outside the Alt Nebula. The short appearance and disappearance of its time is only a moment in the universe.

"Where is the other side of the wormhole?" Luo Yan also looked at the wormhole with a feeling of emotion, and at the same time guessing where the other end of the wormhole was. It was the Milky Way? Or other large galaxies that were more distant? No one knows these unless they directly crossed the wormhole and arrived there.

Su Yichen shook his head. At this moment, his heart was a little complicated. The appearance of the wormhole was an accident, but this accident made him have a thought of exploring the truth. You should know that they are too far away from their own time and space. They are also extremely far away from the Milky Way. The road to home is almost impossible, especially when returning to their own time and space and the earth where they are. This difficulty is even more difficult than finding a needle in a haystack.

However, the emergence of the wormhole made Su Yichen think of one thing. That was their experience of coming to the Androme system through the wormhole. Back then, the fallen wormhole not only made them instantly come from the Milky Way to the Androme system, but also changed the dimension of time, thus allowing them to leap for more than a hundred years in a short period of time.

Maybe they can try it with the wormhole that appears, maybe they can return to their time and space in this way. Moreover, even if they cannot leap for so many years, it is good to get as close as possible. Even if they fail, this is not a bad thing for Su Yichen and the others. You must know that their hope of going home is not only slim, but it is better to take a risk and try it instead.

As for where they would arrive through the wormhole, Su Yichen could not judge, but what if they arrived at an unknown galaxy? What is the difference between this and they have been wandering in the Wormie System? Thinking of this, Su Yichen couldn't help but tell Luo Yan what he was thinking and sought his wife's opinion.

"I believe in your judgment. As long as we are together, we can go anywhere. Besides, why not try it?" Luo Yan replied with a smile. Her eyes also had expectations. Whether traveling through a wormhole is a blessing or a disaster, it doesn't matter. The key is that they can do this together, so what's the fear of failure?

With the encouragement of his wife, Su Yichen quickly decided to travel through this wormhole and make an adventure. Judging from the situation of the wormhole they discovered, it was a natural and accidental wormhole. It was unclear when it appeared and when it would disappear. But one thing is certain, there is only one opportunity to travel through. If you don’t seize the time, the wormhole may suddenly disappear in the universe anytime, anywhere.

Relatively speaking, crossing wormholes is a relatively safe process, but after all, humans don’t know much about it, especially the naturally formed wormholes and artificially opened wormholes. No one can judge its stability, and danger still exists.

For safety reasons, Su Yichen and Luo Yan began to prepare for crossing the wormhole, and at the same time, the spacecraft adjusted its course to fly towards the wormhole. The 7 light-year distance is not far away for the Pioneer spacecraft. After the preparations are completed, they started the Yuemeng flight together, and then jumped out less than a light year from the location of the wormhole. Then the Pioneer spacecraft headed towards the wormhole in a high-speed curvature state. Soon they approached the wormhole. When they arrived at the periphery of the wormhole, they could clearly feel the distortion and oscillation of the surrounding space. In the bridge, Su Yichen and Luo Yan were sitting in a chair in a space suit, holding each other tightly, waiting quietly for the moment of crossing.

"Three minutes left to enter the wormhole, please take protective measures." The reminder from the intelligent brain sounded. Su Wei, as an intelligent life, was responsible for manipulating the spaceship. Su Yichen and his wife had made the final preparations. Three minutes passed quickly. When a pressure was directly transmitted from the oscillation of space to the inside of the spaceship, they knew in their hearts that the time travel had arrived. The two tried to open their eyes wide and tried to see the process of time travel, but at this time they could not see anything, and they could only feel the constant pressure and space oscillation squeezing their bodies.

Compared to the wormhole they encountered in the Alt Nebula, the wormhole they actively crossed this time is much larger in size and size, and the pressure and oscillation caused is much stronger. Fortunately, Su Yichen and Luo Yan both wore Rand civilization spacesuits. This spacesuit is much higher than the spacesuit technology of the Earth civilization and has stronger protection for the human body. Although there was a great discomfort, this time, Su Yichen and his wife did not fall into a coma by the pressure and oscillation. However, the discomfort is certain, but all this soon disappeared. I don’t know how long it took, as if only a moment, when all the pressure and oscillation suddenly disappeared, their eyes lit up and they came to the other end of the wormhole.

"We have traveled through time?" Luo Yan asked, looking at the stars outside.

Su Yichen nodded, and he subconsciously called out the rear of the spacecraft. The wormhole they had traveled through before did not disappear like the wormhole of the Alt Nebula back then, but was still there.

"We are lucky, and this wormhole is relatively stable. In other words, we can still go back to the original place through it." Su Yichen said happily. This is indeed good news. No matter where they are now, as long as the wormhole behind them is still there, they can travel back again and still come to the airspace they were in before.

When Luo Yan saw the wormhole behind her, she also smiled. The good news made them feel much more relaxed. At this time, Su Wei reported on the condition of the spacecraft. The Pioneer spacecraft was in good condition and there was no problem.

"Where are we?"

"I don't know..." Su Yichen could not answer his wife's question because he didn't know where they were. Is they in the Andromeda Galaxy? Or they returned to the Milky Way? Or they came to another galaxy? He didn't know about these. At this time, Su Wei began to scan and compare the surrounding starry sky, hoping to find out the familiar star map features for comparison and positioning. This is a very long and complicated calculation and takes a certain amount of time. Of course, if they are lucky, they may have an answer soon.

But the next time, they said that they were not very lucky this time. After more than ten hours of analysis and comparison, Su Wei did not understand their location in the end. This is a completely unfamiliar galaxy. What’s even more strange is that this galaxy doesn’t seem to be large. The range they can scan and search is only more than one hundred light years away, and there are not many stars in the galaxy. It does not have an ocean of billions of stars like the Milky Way and the Andromeda Galaxy. It just falls sparsely, and looks a bit empty in the universe.

"We cannot locate and we cannot determine our location." The answer given by Su Wei surprised Su Yichen and his wife, but they also expected this situation, but they did not expect that this situation would really happen. Su Wei said that it was impossible to locate and could not determine the location. The other side said that the search could reach the farthest level and still could not find any star system they were familiar with.

So, where did they come? Did they come to a new galaxy that is farther away than the Andromeda Galaxy? If this is the case, it would be like completely lost in the universe. This result would be very terrifying, which means that they have truly become lonely wanderers in the universe and will always drift in the strange universe.

Fortunately, the wormhole behind them is still there, and the road to their return is still open. This is a comforting point. As for whether the dimension of time has changed after crossing the wormhole, they cannot determine whether it has changed. In the universe, the dimension of time is exactly the same in terms of points. The difference is only the difference between points and points. The morning and evening or length of time is only meaningful. Now, without the comparison of time coordinates, no one can determine where the specific time point is.

Now, they are in this strange place, and there are only two choices in front of them. The first choice is of course to turn back immediately, return to the Andromeda galaxy through the wormholes that they travel through, and then continue their sailing in the Andromeda galaxy. The second choice is to explore this galaxy and find out whether there is a cosmic civilization, and maybe there will be some gains.

These two choices were placed in front of Su Yichen and his wife. It was not easy to choose which one. The two carefully discussed it for this and finally decided to choose the latter, which was to explore here. If they did not find it, they would return from the wormhole. Of course, they would take risks in doing this, because the wormhole that came is likely to disappear at any time. If they could not go back before the wormhole disappeared, they would truly become lost wanderers in the universe.
