Can things that only exist in history, that are sealed in the past, that exist in people's memories, be changed?

Hearing Xiao Yu's inquiry, a little confused expression appeared on Ares' face. He thought for a while and said, "Xiao Yu, I don't really understand what you mean. Past......? Now that things have happened, how can they change? ”

"In fact, we have not been able to fully confirm or disprove fatalism until now." Xiao Yu said, "Let's think fatalism is wrong for the time being, that is, the future can be changed, so why can't the past be changed?" ”

"I still don't quite understand." Ares shook his head and said, "For example, you just said that sentence to me, and then changed the past and erased it?" But I already have a memory of it. Perhaps, you mean to say time travel, or to reverse time, to go back in time and change history? ”

"No, it's not about reversing time, and there's no need to go back in time." Xiao Yu said in an accentuated tone, "We don't interfere with time. We stand in the present, change the past, change what has happened. ”

"I don't think so." "It's against logic and common sense. ”

"So, what about the things that have already happened, but you don't know about them?" Xiao Yu said, "Okay, let's elaborate on this issue from another aspect. There are so many things going on in this universe that we don't know anything about, where they're going, what's going on, we don't know what's going on. ”

It's like being in a space millions of light-years away from Xiao Yu. Just like an asteroid hitting another asteroid, although Xiao Yu's computing power is strong, he is not omniscient after all. For these things. Xiao Yu couldn't understand.

"Since we don't know anything about them, we can't know for sure what has happened to them. In other words, their state is in a superposition, and we don't know exactly what their outcome will be. So this raises the question, what exactly is the force that determines what their final form is? What are the factors that determine whether they will affect us in the end? Xiao Yu said quietly, "Such a thing happened to me. When I was fighting against the cosmic civilization, I didn't know where the weakness of the cosmic civilization was. I don't know how to destroy them. At that moment, a message came from one of my internal memories. This informational statement says that they are left over from the musical civilization I once encountered. The purpose is to help me fight against cosmic civilization. ”

"On the surface, there's nothing strange about it, and it shouldn't have been on my radar. But you have to know one thing, before this message appears. I once gave orders to the logic weapon to destroy the civilization of the universe. And the logic weapon chose me to be the executor of this mission. Then I have reason to believe that the logic weapon will arrange some help for me, and I also have reason to believe that there is a close relationship between this sudden information and the help arranged for me by the logic weapon. Then the question arises, is it because the musical civilization has left information within me early on, so the logic weapon arranged me as the executor, or the logic weapon arranged me as the cause and effect. Will this message appear? ”

Which of these two things is the cause? Which one is the fruit? Xiao Yu asked in an accentuated tone.

"Obviously, the reason why the musical civilization left a message within you is the result, and the logic weapon arranges you as the executor." "I don't know what's wrong with that. ”

"Wrong, wrong, it's just one of the possibilities." Xiao Yu shook his head and said, "Continue to turn the question back to the previous one, for those unknown things, we can all think that it is in a superposition state." In the current situation, it is clear that before this information appeared, whether this information existed or did not exist within me, and whether or not the music civilization left a message within me was also in a superposition of "yes" or "no". Until the final result is available, we can't say for sure which one it will collapse into. So, can we think that it is precisely because of the influence of the weapon of logic that the result collapsed into "yes"? It is precisely because I gave the command to the logic weapon to destroy the cosmic civilization, and the logic weapon appointed me as the executor, so in the past, the musical civilization left a message within me? ”

"You mean to say......" Ares thought slowly, and said slowly, "the musical civilization did not leave a message within you in the first place, and it was because of the logical weapon that the musical civilization left this information within you in the past?" But...... This doesn't seem to make sense from logic and timelines. You know, when the music civilization left a message, you haven't been exposed to the weapon of logic......"

"We need to think from the standpoint of the present." Xiao Yu said, "For me, no matter which result it is, that is, whether this piece of information about music civilization appears or not, I will not feel surprised, no matter which result appears, it is reasonable and logical." Until the final result collapses, this event is reasonable and logical no matter how it develops. Since it is reasonable to develop no matter what, what forces determine its direction? Why can't we think that it is because of the influence of the weapon of logic that it ended up being what it is? ”

Or the problem can be simplified a little more, that is, when an unknown event finally has a result, we can trace the process of the event according to the result - it should be noted here that according to the timeline, the process of this event has already happened, it has become history, but how do you confirm that the process of the event that has happened has not been changed? On the other hand, can we be able to determine that an outcome will happen now? ”

"I, I don't really understand what you mean......" Ares said with a snort.

"Another analogy." Xiao Yu said, "Suppose you encounter an assassination one day. Not. The assassination was the result of the event, and the event itself was unknown until it happened. You don't know anything about this incident. ”

"You have to understand that the outcome of events needs to be supported by processes, and these processes are happening in the past. In the past, it may or may not have happened, it was in a superposition. And at this moment when you encounter an assassination. The result collapses, and the end result appears, and you have encountered an assassination. This means that events that may or may not have happened in the past have a definite result, that is, they did happen in the past. You think about it, does this mean. What happens now can determine the past? In other words. Does the present change the past and history? ”

There was a little confusion in Ares' eyes, and he said half-loudly, "I probably know what you want to say...... Are you trying to say that it is because of the existence of logical weapons that you can receive the messages left by the musical civilization, hmm. It's the logic weapon that changes the past, in you. At that time, will there be the result that "musical civilization has left a message"? ”

"No, cause and effect are wrong." Xiao Yu shook his head and said, "It's because of the results that happened to me, so the past had to be changed." In this example, the logical relationship is that the effect leads to the cause, and on the timeline, the cause still precedes the effect. ”

"So...... What does this mean? Ares muttered. Obviously, Ares was very confused at the moment. He had never heard such a fresh statement from Xiao Yu before, and the intricate logical relationships in it made his powerful brain, which was enough to command a war of all civilizations to win, a little unable to turn around.

"This means a lot of things...... Xiao Yu sighed lightly, "This incident with the logic weapon can be regarded as a special case, but let's not forget that there are many events like this one and without the participation of the logic weapon, such as when you accidentally meet someone you have never seen before, such as you saw a star from the sky that you have never seen before...... All of these contingencies can be understood using the logic just now. I even suspect that this is the deeper mystery of the universe, this is the universe as it is. I have a feeling in my heart that if I can continue to dig deeper into this, I may be able to make epoch-making discoveries similar to gravitation, quantum mechanics, and relativity. ”

"As for the application...... Xiao Yu said slowly, "I wonder if a brand-new logic weapon is tempting enough?" Imagine this situation, when you meet a gangster and are about to be killed by a gangster, suddenly lightning falls from the sky, and the gangster is chopped to death at once, or a civilization war, our civilization is about to be destroyed, but at this time, a cosmic disaster occurs, which happens to affect our hostile civilization...... If a logical weapon is created from the logical threads I just mentioned, then it will be able to control all contingencies by altering the past, and let them happen wherever we want them to happen, whenever and wherever we want them to happen. ”

"But why is that?" Ares muttered, "According to this theory, what is the mechanism of our universe?" (To be continued......)

PS: This chapter is the most laborious chapter written since the beginning of this book, I don't know if you understand it...... Rainbow has been thinking about the logical relationship for a long time, and it is only now that she can roughly figure it out. It's really hard to figure out the logic behind this...... And thankless...... Someone said to Rainbow, why don't you write something simple, pretend to be forced to slap your face, upgrade your practice, it's easy to write, and there are many people who love to read it, and you can get more manuscript fees...... But Rainbow wanted to write something unique, and she also wanted to show some of her thoughts all along. In the past ten or twenty years, everyone will forget the book that pretends to slap the face, but the rainbow book, I think everyone will still remember it. Well, that's what Rainbow is after.

Well, I've got to break my promise again today, and that's it. There are still some logical details that have not been thought through, and Rainbow will have to continue to think about it for a while...... In case of a bug, it will be a shame.
