The Pioneer spacecraft was still 20 light-years away from the solar system, which was relatively close, but when they passed by a small galaxy, Su Yichen was surprised to find that this small galaxy was actually a little different from what he remembered. Although he didn't know what the difference was, he could feel it, in order to verify, Su Yichen immediately asked Su Wei to call up the data of this small galaxy in the database for comparison, and when the data comparison results came out, Su Yichen was taken aback on the spot.

In the data comparison results, there is a 3% error between the actual data of small galaxies and the data in the database, and 3% does not seem to be much for a small galaxy, knowing that each small galaxy is composed of a star and the planets and various other celestial bodies surrounding it, and its range and mass are extremely large compared to a Pioneer spacecraft.

Such a large small galaxy will of course undergo certain changes in the course of its operation, such as the orbital position of the planets, or the formation of new celestial bodies or the fragmentation of existing celestial bodies caused by the impact of other celestial bodies. This change is common in the universe, and the same is true for the solar system. But taken as a whole, these changes do not affect the entire small galaxy, unless .......

Now, the data in the database is 3% different from the data of small galaxies in reality, and this 3% change is mainly reflected in the stars and their major planets revolving around the stars. It stands to reason that such a change is unlikely, but if such a change occurs, there are generally two possibilities.

The first possibility, as the Pioneer spacecraft used in the previous use of the Dark Matter Bomb, will cause an imbalance within the small galaxy with such a powerful weapon, and after the explosion, the small galaxy will adjust itself and finally return to normal. But in this whole process. Changes within small galaxies are definitely happening, not to mention a 3% difference, and maybe even a little more.

The second possibility is the evolution of time. Small galaxies also change gradually over time. It's like the formation of a small galaxy from its beginnings to its later refinement, and then to its glory to destruction. In this process, changes in small galaxies have been generated, which is the rule of the universe and the basis of astrophysics. As long as there is enough time, the span of this change is enormous.

These two possibilities are categorized, that is, one is the use of abnormal means to cause short-term changes, and the other is the long-term process of natural evolution. Either way, the end result is consistent, and this discrepancy in the data will occur.

Former. Su Yichen felt that it was impossible, this small galaxy was a very remote small galaxy, it did not have a living planet, it was just no different from those barren small galaxies in the universe. Besides, according to the instrument, there has not been any phenomenon such as explosions in the small galaxy, let alone an attack with a powerful weapon such as a dark matter bomb.

The latter is the only one that can reasonably explain this phenomenon. Only the forces of time can cause such changes in small galaxies. And this time cannot be very short, it must be a very long time. As for how much it will grow, it is impossible to judge for the time being.

This discovery made Su Yichen extremely stunned, and at the same time, a stronger worry surged in his heart. He looked at Raymond, who was sitting not far away. Anthony, who did not make this discovery for the time being, hesitated a little, and then got up and left the bridge. On the way, he sent a message to Luo Yan through his personal terminal, and not long after he returned to the cabin, Luo Yan came.

"What's wrong?" Luo Yan was in a hurry when she came over, she thought that Su Yichen was not feeling well, and asked anxiously as soon as she entered the door.

"I'm fine." Su Yichen tilted his head. Let go of Luo Yan's hand and motioned for her to sit down first.

"Looking for me? What can't you just say? Luo Yan only realized that Su Yichen had something to tell her, and she asked strangely as she sat down.

"Only you know what I'm talking about for the time being." Su Yichen replied.

"Keeping it a secret from Anthony?" Luo Yan immediately understood, she hesitated, and said: "But you have promised him that you will not reveal his identity when you go back, besides, although Anthony is at fault, but so long has passed since the incident back then, why chase him anymore?" ”

Su Yichen smiled bitterly and shook his head: "It's not this matter, of course what I promised will be done, no matter what tricks Anthony used at that time, but a promise is a promise, and this will never change." ”

"And ...... you?" Luo Yan suddenly showed a puzzled expression, she didn't understand why Su Yichen was hiding it from Raymond since this was the case. Anthony called himself into the cabin, and the two of them talked alone?

Just when she was wondering, Su Yichen directly transmitted his terminal data to Luo Yan, and then motioned Luo Yan to take a closer look.

At first, Luo Yan's expression was very relaxed, and even a little disapproving, but when she looked at it for a few lines, she was stunned, raised her eyes and looked in the direction of Su Yichen, and after seeing Su Yichen's grim expression and motioning her to continue looking down, Luo Yan lowered her head again.

After more than ten minutes, Luo Yan's brows were already furrowed, and her expression showed a trace of panic and uneasiness as Su Yichen just now.

"What do you think is the possibility?"

"The second type." Su Yichen replied with some difficulty, Luo Yan opened her mouth to say something, but in the end she still did not refute Su Yichen's judgment, after all, as a scientist, the facts are the best proof, and the information transmitted to her by Su Yichen has fully confirmed this, and his hypothesis is also the most likely.

Thinking of this, Luo Yan suddenly felt a burst of sadness, which suddenly surged from the bottom of her heart and could not be suppressed. Her eyes moistened, and then tears fell, and even sobbed quietly.

"Don't cry...... Don't cry! Seeing his wife crying, Su Yichen hurriedly hugged her, reached out and patted her gently on the back. But this couldn't stop Luo Yan's crying, and even Su Yichen's nose was sour.

"We ...... We can't go back, can we? We can't see Xiao Zhe anymore, can we? And Su Li, and our home, isn't it ......? ”

Luo Yan asked with tears in her eyes, her voice was so weak, at this moment she was crying helplessly like a girl who had lost everything. Su Yichen wanted to tell her that it wasn't, but he couldn't say it. Two lines of hot tears could no longer be suppressed, and they also fell.

The comparison of the data and the results have told them the truth, and the truth is that the time coordinates they are in have changed dramatically from the original time coordinates. Perhaps, this explanation sounds incomprehensible to ordinary people, so it may be easier to use another explanation. The explanation for this is that they are now far from when they left the solar system, and the gap is very large, perhaps even so large that they cannot imagine it.

back then. They accidentally came to the Andromeda Galaxy through a wormhole, and then returned from the Andromeda System. Little did they know that the journey had taken 400 years. When they returned to the solar system, they found that due to the distortion of time and space in the wormhole and the change of time coordinates, they had spanned such a long time, and at this time, there were few people who knew each other on the earth, and those old friends had grown old one by one and passed away, and the earth had also changed in these years. They don't even recognize it.

400 years is a long time, enough to change everything that a person knows and even knows about it. But in terms of the time dimension of the entire universe, 400 years is very short, so short that it is just an inconspicuous drop of water in the long river of time.

Judging from the differences in the changes in this small galaxy, the problems faced by Su Yichen and them are more serious than the last time. This time, just from the preliminary calculations, it can be known that they have spanned a longer and longer period of time, maybe this period is a thousand years? Years? Or even 100 million years? It is impossible to know exactly how much. Only wait until you return to the solar system and see the familiar earth and the warm sun. Using the actuarial comparison of the solar data on their spacecraft to find out the exact time.

Of course, this method does not limit the sun, according to the theory of astrophysics, as long as a star can be accurately located, the results can be obtained according to the growth and decay of its star. But there is also a mistake in doing this, or there is still a trace of luck in Su Yichen's heart. Perhaps nothing has changed since returning to the familiar solar system, and now these are just errors of judgment.

Luo Yan sobbed in a low voice for a while, and only gradually eased up under Su Yichen's comfort. After so much time, everything that was familiar before is long gone, including his children Su Zhe and Su Li. That's too much of a blow for a mother. Luo Yan couldn't stand this blow for a while, but she was an excellent scientist after all, and when they left the solar system, they anticipated the danger, and even prepared to sacrifice in the universe. Luo Yan tried to control her emotions and eased from the extreme sadness, at this moment she also knew why Su Yichen would tell her about this alone instead of on the bridge, he was thinking about Raymond. Anthony's endurance, these days on the way home, this old guy seems to be rejuvenated, and he seems to be extremely excited. It is indeed here, after so many years away from home, I even thought that I would finish my life in a distant place, but who would have thought that there would be a day when I would go home.

"I'm fine, don't worry, I'm really okay?" Wiping away her tears, Luo Yan said to Su Yichen, and the mood she showed now is indeed much better, and she has basically returned to normal.

"Don't worry, maybe it's just a miscalculation, maybe everything will be the same when we go back."

Su Yichen's words of comfort sounded a little fake, but Luo Yan felt a kind of peace in her ears, she nodded with a reluctant smile, and at the same time worried: "You don't plan to tell Anthony?" If everything goes as expected, he'll hate you. ”

"Hate it, hate it, at least he's happier than us now." Su Yichen sighed, sometimes people who don't understand are indeed happier than people who know more, there was a famous literati in ancient times who wrote a banner of "rare confusion", maybe this is the case, in this case, maybe ignorance is the real happiness, and they who know the truth are in sorrow.

Luo Yan understood the meaning of Su Yichen's words, she didn't say anything anymore, in her opinion, Su Yichen was right to do this, on the one hand, it was to let Raymond. Antony was happy for a while, better than they were so sad. On the other hand it is also to reduce the uncertainty factor that no one knows once Raymond. What happens when Anthony knows the truth. As for the truth that will eventually be known by then, then let's talk about it then, and now they can only take one step at a time.

The Pioneer spacecraft continues to move forward, getting closer and closer to the solar system. As they got closer to the solar system, the more certain Su Yichen and Luo Yan were that the time coordinates they were in had changed a lot, because many aspects of the cosmic space near the solar system were a little different from what they were familiar with, and only the changes of time would lead to such a result, and there was no other explanation other than that.

"Hey! I'm going home soon, what's going on with you two these days? Although they tried their best to hide their hearts, Su Yichen and Luo Yan were in Raymond. Anthony still pretended to be the same as usual, but Raymond. Who is Anthony, if you talk about understanding people's hearts, this old fox must be the first among the three, Su Yichen and his wife are just scientists, and their emotional changes can't be hidden from the old guy at all.

"It's nothing, maybe I'm just tired." Luo Yan replied with a smile, and Su Yichen on the side also smiled and nodded to indicate that this was the case, and at the same time took the initiative to chat about the past on the earth, including asking Raymond. What did Anthony want to do when he returned to Earth?

"Sue, did anyone tell you that you're not good at lying?" Who wants to, Raymond. Anthony shook his head and asked seriously.

"What did you say?" Su Yichen asked puzzled.

Ramon. Anthony shrugged his shoulders, then pointed to his eyes, "You may have forgotten who I am?" I'm Anthony, Raymond. Anthony! I am a big man who used to be high, do you think that as a successful person like me, I only rely on the wealth and luck left by my ancestors? No, no! There has never been a lucky one in this world, never! If I had been deceived by your childish lies, I would have died to ashes, and I would not have stood in front of you now and said such things. ”

Ramon. Anthony's words silenced Su Yichen and his wife, only to hear him continue: "The dodge in your eyes just now, as well as the sorrow hidden in your wife's expression, all tell me that you have something to hide from me." By the way, your personality is not suitable for lying, and you are trying to distract me from mentioning things that are inconsequential, right? Unfortunately, it didn't work for me. Say it, tell me! What exactly happened, I think as a member of the ship, I have the right and the right to know. ”

In Raymond. In Anthony's gaze, Su Yichen let out a long sigh, he knew that he couldn't tell the truth anymore, and finally he decided to tell the other party the truth. (To be continued.) )
