Seeing the time machine placed in the basement, Su Yuan couldn't help but breathe a sigh of relief, its existence was not only related to the retreat in the future as a last resort, but also showed Su Yuan a world she was familiar with.

The basis of spiritual existence is matter, and if matter changes, it is also a fatal blow to the spirit.

Fortunately, so far, everything is in line with the previous world, and this sense of familiarity has always relieved the pressure on Su Yuan. Just imagine, if she came to a new world world composed of countless familiar people, but it was completely different from the original world world, under the huge gap, it would be strange that she could maintain her composure.

Even if it is a familiar person, he still lives a familiar life, but there is no time machine in the basement, so there will also be a feeling of "unreal" attacking Su Yuan's psychology. Because in her subconscious, there should be a time machine in the basement!

This feeling is very subtle, in fact, to put it bluntly, it is a kind of recognition, a recognition of the authenticity of this world.

The appearance of the time machine in front of her at the moment made Su Yuan have more substitution for this world, although this substitution made her senses have a vague overlap on the edge of the two worlds, but then again, if Su Yuan can't recognize the world world in front of her, and just treats it as an illusory game, an existence that can leave and abandon it at any time by time machine, then how can she, who lacks a sense of urgency, burst out of all her potential?

There must be a gain and a loss, depending on how to evaluate.

Coming back from the basement, Su Yuanjing sat on the bed and meditated, vaguely grasping a trace of inspiration. But I don't know what the consequences of doing this will be.

The time is unconsciously eleven o'clock, here. Su Caiwei finished a chapter, and after uploading it to Dianniang, the whole person leaned over.

"Xiao Yuan. Still thinking about things?"

Su Yuan snorted, picked up the mobile phone that Su Caiwei bought for her today, looked at the time, and said in surprise: "It's so late." ”

Su Caiwei smiled and said: "Yes, I usually see that you are lazy and don't like to use your brain, but today you are so engrossed, look at it, your brows are wrinkled together." ”

"Hey, there's no way, there are some things I don't want to get through and panic. Sad!"

"Don't worry, there's always a way. ”

Su Yuan nodded silently, "It's man-made, and I believe there will be a way." ”

Su Caiwei said thoughtfully: "The so-called one person counts the short, and the two count the long, otherwise, you tell me what you think, and I will help you think of a way, of course, before that, you must first tell me a detailed theory about the boundary of the world." ”

looked at Su Caiwei's sincere and beautiful eyes. Su Yuan suddenly thought of a lot. She suddenly squinted her eyes, and thought happily in her heart: It seems that her mother feels sorry for her and is ready to help her share the pressure together.

But that's right, Su Caiwei has a lot of experience. There are a lot of things that must have been thought through more than you are.

The last time I explained my origin to her, I only briefly mentioned the concept of the world boundary, but did not tell her about the detailed theory of the world and the world, so I sorted out the following thoughts and said: "The world is a concept mentioned in Einstein's paper "On the Electrodynamics of Moving Bodies" published in 1905. He integrates three-dimensional space and time into four-dimensional space-time, and the trajectory of particles in four-dimensional space-time is the boundary of the world. If we can describe the position of the particles at any moment. We describe the history. ”

Since time is eternal and endless, the trajectory of particles in four-dimensional space-time. In fact, it is the experience of a particle's life, and countless particles have countless world boundaries, so all the particles that make up a person are gathered into a person's "world boundary", which is enlarged to the entire world and the world, and there is a "world line" that summarizes all the history of the entire world and the world.

"Is the theory of the boundary of the world the pure mathematical theory in the Minkovsky space-time map?" Su Caiwei suddenly asked, because she had a wide range of knowledge and had a very clear concept of the boundary line in the Minkovsky space-time map.

In a space-time diagram, the entire life history of an object can be represented as a winding line, which is called the boundary line.

Su Yuan didn't know what Min Kewsky space-time map was, so he was stunned and said depressedly: "Mom, can you not interrupt, I don't understand what you said!"

"Ha Lu Ha. Go on!" Su Caiwei raised her eyebrows, looked at Su Yuan's embarrassed expression and covered her mouth and smiled.

Su Yuan said: "Anyway, a world boundary line is a kind of 'history', in the theory of the world Lu boundary, the world under each world is real, the difference is only their respective development trajectories, because there is only one world and the world is alone, so at the same moment, there is always only one world line that presents the real world and the world and the world can only choose to show it in the form of a certain world and the world, and before this world line is not jumped, the world and the world under the other world world boundaries do not exist. ”

The existence of the boundary line is a bit like the superposition state in quantum mechanics.

A superposition state is a state of a particle that is superimposed on several eigenstates, which is indeterminate, and only when a "measurement" is made will it appear as a measured state, which may be any of its eigenstates.

The existence of the world boundary is similar to this, countless world boundaries exist together in the form of superposition, but there is only one world and only one world and only one world and the world and the world can deduce "history" in the form of "intrinsic state"! The jumping of the world boundary line is to break the intrinsic state of the original world boundary and let another world boundary appear in the form of an eigenstate.

"Can you be specific, it's a bit ...... here" Su Caiwei looked at Su Yuan, her eyes shining with innocence.

"For example, there is now a world realm, in order to distinguish it, so we named it 'No. 1', the No. 1 world is a real world realm, with its own development trajectory, and this trajectory is called 'fate' by the beings in the No. 1 world realm, and we call it 'the world boundary', the development trajectory of the No. 1 world is the No. 1 world realm, and it is a string of unique numbers to characterize it mathematically. ”

"One day, a scientist in the No. 1 world realm invented a time machine, and through it came to the past, and the person who went back to the past did a lot of things to try to influence the future, but in fact he only found out after he returned. It is precisely because of what he has done in the past that the history of the No. 1 World Realm has developed to what it is now. ”

In other words. He walked around the No. 1 World Realm, and the fate of the No. 1 World Realm had already engraved the fact that he would cross it in its book of events. His actions simply happened to fulfill the records in the event book. ”

This is easy to understand, and Su Caiwei couldn't help but nod.

"Then for a long time, the scientists of the No. 1 World Continent have accumulated a large amount of analysis data through various experiments, and their understanding of the essence of the World Continent has become deeper and deeper, and finally one day they have found the essence of the World Continent Boundary, so they invented a time machine again, which fully grasps the elements of the World Continent Boundary, so that it can jump the World Continent Boundary. Jump from the 'No. 1 World Boundary' to another World Boundary. ”

"The act of jumping over the boundary of the world is actually no different from ordinary travel through history, except that when the traveler takes a time machine to leave the first world or enter the second world, a certain mechanism on the law of time is triggered, which causes the original number one world world to collapse, and all the information (energy) of the first world world collapses into another world world, which is later the second world. ”

"So did the time machine that can jump the world boundary line choose a certain world world line to enter, and then cause the world world to collapse into the world world under the world world line it entered, or are the two synchronized?"

In other words, in the end, the boundary between the world and the world was chosen first. Or is it the worldly realm, or is it the same as both?

Su Yuan said: "Jumping the boundary of the world is a popular saying, and the 'world boundary' itself is a simple number that represents a world and has left the world world. It doesn't mean anything. In other words, jumping the boundary line of the world is essentially going back to the past, but because the law of time is triggered, the 'history' after a certain crossing point has a certain deviation. This deviation is also known as the butterfly effect, and its magnitude depends on the degree to which the law of time is triggered. ”

There is no jumping off the boundaries of the world. Space-time shuttle does not trigger the interference of the laws of time and space, and the same boundary of the world is the same fixed history. There is no butterfly effect, but the act of jumping is enough to cause the interference of the laws of time and space, and stir up a ripple in time and space, and the butterfly effect will occur, and the different future directions will inevitably be a new world boundary.

The boundaries of the two worlds are different, so they are called jumping the boundaries of the world.

Su Caiwei suddenly realized, "The boundary of the world is just a mathematical symbol, in the final analysis, it is a summary of the history of a world world, and there will always be only one real world world." ”

"Yes, nine times out of ten, my arrival has jumped the boundary of the world, so my existence will cause the future of the current world to develop in a future that is different from what I remember. As for how much I will change, it will depend on how much influence I can exert over this worldly realm. ”

Just imagine, if the butterfly effect is allowed to exist and send a small person to the battlefield of World War II, if he is just a small soldier, then his butterfly effect may only detonate a mine in advance, but if he is a general, it is possible to change a war zone, and similarly, if he is the head of a country, then he may change the entire trend of the war.

If Su Yuan is just a small person, then all she can change is the fate of a few people around her, and it depends on whether the torque of history is weak enough.

"I understand the general situation, but what are your plans?"

"It depends on the number displayed by the world's boundary sniffer. Su Yuan smiled and said, "If the World Boundary Sniffer proves that I have jumped the World Boundary Boundary, then everything I have done is meaningful, on the contrary, if the World Boundary Boundary value is still the one in my memory, it means that no matter what I do, it has happened in 'history', but it still leads to a collapsed future......

I know that what I do is useless, so why bother to do it.

Fortunately, the Shilu Boundary Sniffer will be made by Su Mengyuan and others in a few days, and all Su Yuan has to do is to wait patiently for a few more days.

Next, Su Yuan told him about his plan, Su Caiwei's eyes lit up when she heard it, she frowned and thought about it, and nodded: "If you can develop according to your plan, maybe you can really catch that glimmer of life." ”

"So, we have to wait for the value of the world boundary to come out......"

Su Yuan said softly, feeling nervous about facing the big exam. (To be continued......)
