"Black holes?" Su Yichen first thought that it was a black hole, because in this airspace, space was twisted in a strange way, and some matter was constantly surging towards the center of that airspace, which was like a vortex in a pond, and what was thrown into the edge of the vortex would be attracted by the vortex and pulled into the inside of the vortex.

But when the idea of a black hole just flashed through his mind, Su Yichen immediately denied it, in the space voyage, Su Yichen has not seen a black hole, especially when they are on Ike's spaceship, they have experienced a long journey from the Milky Way to the Andromeda Galaxy, and they have found a lot of black holes in the universe along the way.

A black hole is a bizarre celestial phenomenon, when a star reaches the end of its life, the star's material will continue to collapse and compress, and attract a large amount of matter in the surrounding space, and finally become a special celestial body with infinite matter and infinitely small volume. When this kind of matter is formed, the black hole is also created accordingly, in fact, the black hole is a special celestial phenomenon on the periphery of this special matter, it has a great attraction, according to the theory that this gravitational force is almost so great that even light cannot escape.

In the twentieth century, scientists on Earth put forward the theory of black holes. For ordinary people, black holes are extremely terrifying, but in fact, when you go directly into the gravitational range of the black hole during spaceflight, the consequences are of course very serious.

But in fact, during space travel, special celestial bodies such as black holes are not as terrible as imagined, and it is true that black holes have great gravitational pull and can pull all objects within its gravitational range. But in fact, although there are many black holes in the universe, it is impossible for intelligent life to become a cosmic civilization to be stupid enough to fly directly towards black holes. Due to the peculiarity of black holes, it is easy to be discovered in advance in the universe, as long as the gravitational range of black holes is avoided. Black holes are not scary.

However, the black hole that appeared in the airspace in front of him was somewhat different from the black hole that Su Yichen imagined, because he could actually see the light floating at 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 gravitational pull of the black hole is so strong that even light cannot escape, if this is really a black hole. Then they can't see the light.

So, what is this not a black hole? Su Yichen looked at this strange celestial body, and another celestial state that he was familiar with suddenly flashed in his mind, that is, wormholes.

Wormhole, which is a celestial phenomenon in the universe that is more special than black holes, is a kind of passage connecting space and space in popular terms. Su Yichen and they are no strangers to wormholes, as early as when they accidentally fell into a wormhole and came to the Andromeda Galaxy, and later they returned to the galaxy through the artificial wormhole opened by the Rand civilization.

Although there is a difference between the two wormholes, the former is naturally generated. And the latter was created by the Rand civilization with the help of powerful technology. But a wormhole is a wormhole, its essence will not change, and there is a great difference between a wormhole and a black hole, although the two seem to be somewhat imaginary on the surface, it is still easy to distinguish.

As expected, Su Wei conducted a detailed scan of this celestial body, and it didn't take long for the results of the scan to come out, and the results were indeed as Su Yichen thought. It's a wormhole.

"I didn't expect us to encounter a wormhole." Looking at the wormhole in the distance, Su Yichen couldn't help but sigh with emotion. in the universe. The appearance of wormholes is extremely accidental, and their number is much smaller than that of black holes. What's more, wormholes are created by special factors, and they don't exist for a long time like black holes. Sometimes some wormholes appear and disappear for a short period of time, such as the wormhole they fell into on the outer edge of the Oort Nebula, and its appearance and disappearance are only a brief moment in the universe.

"Where is the other side of the wormhole?" Luo Yan also looked at the wormhole with emotion. At the same time, I guessed what the other end of this wormhole was. Is it the Milky Way? Or are they other, more distant galaxies? No one knows any of this, unless they go straight through the wormhole and get there.

Su Yichen shook his head, his heart was a little complicated at this moment, and the appearance of the wormhole was an accident. But this accident gave him an idea to find out. You must know that they are now too far away from their own time and space, and they are also extremely far away from the galaxy, and the way home is almost impossible, especially to return to their own time and space and the earth where they are, this difficulty is even more difficult than looking for a needle in a haystack.

However, the appearance of the wormhole made Su Yichen can't help but think of one thing, that is, the experience they once had come to the Andromeda Galaxy through the wormhole. Back then, the falling wormhole not only brought them from the Milky Way to the Andromeda Galaxy in an instant, but also changed the dimension of time, thus making them leap over more than a hundred years in a short period of time.

Maybe they can try it out with the wormhole that appeared, maybe they can return to their own plane in this way. What's more, even if you can't leap through so many years, it's good to get as close as possible. Even if it doesn't work, this is not too bad for Su Yichen and them, you must know that their hope of going home is not only slim, but it is better to take the risk than this.

As for where he would reach through the wormhole, Su Yichen couldn't tell, but what if he arrived at an unknown galaxy? What's the difference between this and their constant wandering in the Andromeda Galaxy? Thinking of this, Su Yichen couldn't help but tell Luo Yan what he was thinking, and asked for his wife's opinion.

"I trust your judgment, as long as we are together, we can go anywhere, besides, why not give it a try?" Luo Yan replied with a smile, there was also expectation in her eyes, whether it was a blessing or a curse to pass through the wormhole, it didn't matter, the key was that they could do it together, so what was there to fear if they failed?

With his wife's encouragement, Su Yichen soon decided to make a risky attempt to cross this wormhole. Judging from the situation of this wormhole they found, it is a natural and accidental wormhole, and it is unclear when it will appear and when it will disappear. But one thing is for sure, there is only one chance to cross, and if you don't hurry up, then the wormhole may suddenly disappear in the universe anytime and anywhere.

Comparatively speaking, crossing a wormhole is a relatively safe process. But after all, humans don't know much about the strange celestial body of wormholes, especially the difference between naturally formed wormholes and artificially opened wormholes, its stability cannot be judged by anyone, and the danger still exists.

For the sake of safety, Su Yichen and Luo Yan began to prepare for crossing the wormhole, and at the same time, the spacecraft adjusted its course and flew in the direction of the wormhole. 7 light years away. It was not far away for the Pioneer spacecraft, after the preparation was completed, they started the over-migration flight together, and then jumped out of the wormhole less than a light year away, and then the Pioneer spacecraft sailed towards the wormhole in a high-speed curvature state, and soon they approached the wormhole, and when they reached 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 sat in the chair in their spacesuits, their hands clasped together, quietly waiting for the moment of crossing.

"There are still three minutes to enter the wormhole, please take precautions." The reminder of the wisdom brain sounded, and Su Wei, as an intelligent life, was responsible for controlling the spaceship, and Su Yichen and his wife had made the final preparations. Three minutes passed quickly, and when a pressure was transmitted from the oscillations of space directly to the interior of the ship, they knew in their hearts that the crossing had come. The two tried to keep their eyes open, trying to see the process of crossing over. But at this time, they couldn't see anything, only felt the constant pressure and spatial oscillations squeezing their bodies.

Compared to the wormhole encountered in the Oort Nebula, the wormhole they actively crossed this time was much larger and larger, and the pressure and oscillations caused by it were much stronger. But fortunately, Su Yichen and Luo Yan were both wearing the spacesuits of the Rand civilization, which were much higher than the spacesuit technology of the Earth civilization back then. The protection for the human body is also stronger. Although there was a lot of discomfort, this time Su Yichen and his wife were not squeezed by this pressure and oscillation, but the discomfort was certain, but all this disappeared quickly. I don't know how long it took, it seemed like it was just a moment. When all the pressure and oscillations suddenly disappeared, their eyes lit up and they came to the other end of the wormhole.

"We crossed over?" Luo Yan asked, looking at the starlight outside.

Su Yichen nodded, he subconsciously called up the back of the spaceship, the wormhole they had passed through before had not disappeared like the wormhole of the Oort Nebula back then, but was still there.

"We're lucky, this wormhole is relatively stable, which means we can 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, it is a big deal to travel back again, and they can still come to the airspace where they were before.

When they saw the wormhole behind them, Luo Yan also smiled, and this good news made their hearts feel a lot easier. At this time, Su Wei reported the condition of the spacecraft, and the Pioneer spacecraft was in good condition without any problems.

"Where are we?"

"I don't know ......." Su Yichen couldn't answer his wife's questions because he didn't know where they had gone. Is it in the Andromeda galaxy? Or back to the Milky Way? Or to another galaxy? He didn't know any of this, and at this time, Su Wei began to scan and compare the surrounding starry sky, hoping to find out the star map features they were familiar with for comparison and positioning. This is a long and complex calculation that takes a certain amount of time. Of course, if they're lucky, they might soon find out.

But then they said that they were not very lucky this time, Su Wei after more than ten hours of analysis and comparison, and finally did not figure out where they were, this is a completely unfamiliar galaxy, what is even more strange is that this galaxy seems to be not big, with the range they can scan and search is only more than a hundred light years away, and there are not many stars in the galaxy, it is not like the Milky Way and the Andromeda galaxy with an ocean of hundreds of millions of stars, but it is sparsely landed, and it looks like the universe is a little empty.

"Can't locate, can't judge where we are." The answer given by Su Wei surprised Su Yichen and his wife, but they also expected this situation, but they didn't expect it to really happen. Su Wei said that he couldn't locate it, and he couldn't determine the location, which said that the search could reach the farthest point and still couldn't find any of the galaxies they were familiar with.

So, where exactly did they come to? Could it be that you have come to a new galaxy that is more distant than the Andromeda Galaxy? If this is the case, it is equivalent to completely losing their way in the universe, and this result will be very terrifying, which means that they have truly become lonely wanderers in the universe, and thus will drift forever in the strange universe.

But fortunately, the wormhole behind them is still there, and their way back is still open. This is a comforting point, as for whether the dimension of time has changed after passing through the wormhole, they can't be sure. In the universe, the time dimension is exactly the same from the point, its difference is only between the points, the morning or evening or the length of time, only the comparison is meaningful, and now in the absence of time coordinates comparison, no one can determine where the specific time point is.

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

These two choices are placed in front of Su Yichen and his wife, and it is not easy to choose which one to choose, so the two discussed it cautiously, and finally decided to choose the latter, that is, to explore here, and then return from the wormhole if they are not found. Of course, they are taking risks in doing so, because the wormhole is likely to disappear at any time, and if they don't go back before the wormhole disappears, they will truly become a wanderer lost in the universe.

The decision was made, and the Vanguard spacecraft headed towards a small galaxy closest to them, intending to go there first to see the situation, according to calculations, this small galaxy was about 25 light-years away from their location, so the Vanguard spacecraft launched a jump, and the jump start and flight went smoothly, but when they came out of the jump flight, the scene in front of them made everyone stunned.
