The existence of cause and effect is a logical concept.

The law of cause and effect points out: sow melons and get melons, and sow beans and get beans. Buddhism, on the other hand, holds that anything can be a cause or an effect, and that there is no absolute cause or effect. The cause mentioned in Buddhism is sometimes used in conjunction with the cause, and the cause is the cause and the effect.

Cause in the narrow sense refers to the direct cause or intrinsic cause of the effect, while the cause mainly refers to the co-cause or external indirect condition that produces the effect.

Cause and effect in a broad sense also includes dependence, and cause and effect is an understanding of the interrelationship between existence and behavior, especially the relationship between the front and back.

Normally, when time and space are like a river moving forward, the existence of cause always precedes effect, which is what everyone can recognize.

However, when a period of time and space is confused, for example, a person suddenly returns from 2000 to 1999, then the timeline that originally traveled forward forms a "ring" at the moment of travel, and the moment this person touches at the two points in time on the timeline returns from 2000 to 1999, and then the timeline is straight again, and what the traveler did in 1999 becomes the "history" of 2000. From the point of view of cause and effect, the person between 1999 and 2000 who has not yet crossed is the cause of the development after 1999.

Just like the qiē that Su Yuan experienced at this time, frankly speaking, it was a series of chain reactions caused by a certain "cause", and their "fruit" was of course perfect. But if there is no "cause", then this "effect" is not perfect, at least its existence is not supported by the law of cause and effect.

And what Su Yuan has to do at this moment is to try to supplement this "cause", so that the "effect" that is presented now can be truly fixed!

"So what should we do to count supplementary causation?"

The question is critical, what kind of behavior is considered to be a causal complement?

Su Yuan smiled and said: "Actually, it's very simple, let the world line be restricted! Make it β = 0.8 or β = 1.2 or β = 1.0, let them all become something that will inevitably happen in a new world line! That is to say, we want to make the act of jumping the world line impossible, and make the behavior that we once thought we had jumped the world line an illusion!"

Speaking of this, Su Yuan accentuated his tone. "If there is a world line called 'γ' outside the frame." The story that happened in the γ world line is the process of us constantly jumping in the β world line, so the behavior that we once thought we had jumped β world line, for the γ world line, is it still shuttling within the framework of the world line?"

Gao Jun inhaled in surprise. I closed my eyes and pondered for a moment. "You mean to find an absolute timeline." All of our previous actions are actually developing in the positive direction of time on this absolute timeline, and there is no such thing as a past behavior of traveling to the γ worldline?"

Ji Ye Hao and Su Mengyuan also suddenly realized at this moment, only Shen Linfei was still skeptical: "But these are our subjective guesses." It is impossible for us to suddenly have an absolute timeline in this world that conforms to the framework of the γ world because we believe that there is a more macroscopic γ worldline, how can we prove its existence?"

yes, how do you prove it?

"You don't have to worry about this, the proof will be given later, we are just using this conclusion in advance now!" Su Yuan smiled, at this moment she was like a scientist full of intellectual beauty, in fact, she didn't tell everyone, what she said at this moment was basically heard from Gao Jun of the β=1.2 world line, she just relayed the results of others.

"According to the classification of time machines, we already know that they have two types: the first generation of time machines that can only travel within the same world line without changing history, and the second generation of time machines that can jump the world line and change history. However, as Gao Jun β=1.2 delved deeper, he discovered another possibility, which is to save the absolute timeline of zài!"

"Saving zài has an absolute timeline, which means that there is a more macroscopic world line, and the previous generation of time machines and the second generation of time machines may not have really changed history, even though it is back to a year ago in the β world line, but in a more macroscopic γ world line, in that absolute timeline, it is still developing in the positive direction of time passing. ”

At this time, the so-called first-generation and second-generation time machines are useless, because although they are called time machines, they cannot go back to the past at all in the absolute timeline, and the 'past' they have traveled through before is nothing more than a false 'past' that we consider to be the past. ”

"Could it be that the other Gao Jun has invented a third-generation time machine that can travel on an absolute timeline?"

Su Mengyuan withstood the bombardment of the information bomb, and quickly digested the information that Su Yuan transmitted to her with her flexible little head, and said by inference.

Su Yuan nodded: "That's right, Gao Jun from β=1.2 did build the third-generation time machine before he died in 2000!"

"Where's the time machine now?"

Everyone asked movingly.

"It's in the basement!"

“……”

Seeing that everyone threw "not very convincing" glances at her, Su Yuan lamented her fading majesty, "Randy, switch scenes, and raise the time machine!"

"Okay!"

The cute Lori Randy replied crisply, and the dense primeval forest disappeared in the next second, and a pure white scene was restored in the basement, but if you listen carefully, you can hear a rumbling sound, the sound is very soft, some like a gear turning.

Then, the ground cracked open and a huge goose-egg-shaped time machine rose up.

A thought flashed through the minds of Su Mengyuan and the rest of the people at the same time-how many floors is this basement, it can't be hollowed out, right?

The time machine in front of me is milky white. The "goose egg" with a waist circumference of four meters and a height of five meters is the same as the time machine that appeared in the first video, and it can even be said that it is the same thing at all! Four steel structure supports more than 30 centimeters thick at first glance look like spider legs, and the lower end is wrapped with thick rubber material, so as not to cause puncture damage to the ground, and it looks mighty and domineering!

Su Yuan introduced: "This is the third-generation time machine invented by Gao Jun! It is transformed on the basis of the original second-generation time machine!"

At this time, Ye Hao slightly understood Su Yuan's thoughts, he frowned and said: "In the time machine recording of the first video, before Su Mengyuan used the time machine, the time machine had two records of crossing, the first time crossing. The time machine is still a second-generation time machine. It was made by Gao Jun with β=1.200011, and came to the world of β=1.0 with Shen Linfei, of course, because of the several [backtracks] of the dream source. The world that actually came to the record should be the current world of β=1.000112!"

"The second crossing in the record. It is from the world of β=1.000122 to the world of 0.8 where Su Mengyuan was at the time!Then the time machine in front of him has completed the actual experience of traveling from β=1.2 to β=1.0. Is it going to be sent to a world with β=0.8?"

Hearing this, Su Yuan couldn't help but look at Ji Ye Hao with admiration, and cast a burning look at him. Encouragement: "You're right! I discussed with Gao Jun, β=1.2, about the order of the world lines on the timeline. ”

"We have come to the conclusion that on the absolute timeline, the world with β=0.8 is the earliest to appear, and then there will be β=1.2 worlds and β=1.0 worlds!"

"And after watching the first video, I think everyone should see a contradiction, that is, the source of the β=0.8 Charlene! The reason why the world line has two completely different future directions of β=0.8 and β=1.2 is that the β=0.8 world line has a Charlene, and the β=1.2 world does not have Charlene!"

After Su Yuan finished speaking, Shen Linfei seemed to think of something, and said, "If the introduction of the world line change is due to the observer effect, β then Charlene is the observer who caused the world line to diverge from the β=1.2 world?"

Su Yuan nodded: "Yes, Xia Linfeng is the observer who caused the differentiation between β=1.2 and β=0.8!Combined with Xia Linfeng's statement that she came from the world of β=1.2, it once made me think that the world of β=1.2 actually happened before the world of β=0.8, but according to my own experience, I know that the world that gave birth to me β=0.8 must have happened before β=1.2, which produced a contradiction!"

Gao Jun thought for a while and put forward a more reasonable explanation: "Unless β=0.8, β=1.2, and β=1.0 are constantly changing, only in this way can this contradiction be resolved! That is to say, before the world that gave birth to your β=0.8, there must be a world that gave birth to Charlene β=1.2, and with the arrival of Charlene, the world line changed from the β=1.2 that gave birth to Charlene to the β=0.8 that gave birth to you, and then you went through a long river of time and lost your memory to another β=The world of 1.2, and then because of the arrival of β=1.2, the world line becomes β=1.0, and your memory is restored, so the reincarnation that had happened countless times before came to an end. ”

"If there is a cycle, wouldn't it be a process of countless β = 0.8, countless β = 1.2, and there are also countless 'Su Yuan' crossing and losing their memory?"

Gao Jun nodded solemnly: "Theoretically speaking, this is the case, and the 'Su Yuan' who gave birth to you is precisely an accident of quantitative change after countless reincarnations! The world line accidentally jumped to β=1.200011, and then Gao Jun, who β=1.2, came over, and accidentally restored her memory, and the world line changed to β=1.0." ”

Countless accidents eventually shape an inevitability, and Gao Jun knows that history is a patchwork of accidents one by one.

But is this really the case? Gao Jun couldn't help but fall into confusion.

Seeing that everyone was being bypassed, Su Yuan smiled softly, no longer hiding, she said: "I did think so at first, but after we discovered the absolute timeline, Gao Jun and I suddenly understood from β=1.2. In fact, Charlene is not wrong to say that she comes from a world of β=1.2, and it is not wrong that the β=0.8 world line occurred before the β=1.2 world line! And this world is not β=0.8, β=1.2 constantly circulating, and then inadvertently producing β=1.0; to be exact, this world has only experienced one cycle!"

"Because our previous circular speculation was based on the lack of 'cause', and if the 'cause' is completed, this qiē is actually very natural!"

Everyone was stunned, as if they had touched something.

What is this 'cause', of course, as an observer, causing the difference between β=1.2 and β=0.8, but there is no way to explain the "source" of Charlene......?
