Even if it's a fake daughter, you have to be brave

What is a timeline?

In the past, 24-year-old Shen Hui said this to Shen Yue.

"There is only one timeline. If you look at it from a distance, it is a straight line, but if you look carefully, you will find that this line is uneven, thick and thin.

The thick place is the time that has been covered, which means that someone used backtracking on this time line and generated a new time to cover the original time line, causing this time line to become thicker.

And the more times you cover, the thicker the timeline will become.

Theoretically speaking, if the timeline can be observed intuitively, then the thickness of the timeline can be used to judge whether the world has experienced backtracking for a certain period of time, and it has been backtracked many times.

But in fact, the timeline can only be recognized in the three-dimensional space where human beings live, but cannot be observed.

This also leads to the fact that once the timeline is restarted, no one can perceive it except the person who restarted the timeline and overwrote it can remember all the time. "

"Xiao Yue, do you feel that you only live this time?"

"But actually, this is your 26th timeline, isn't it interesting?"

Shen Yue was never interested in Shen Hui's research before, after all Shen Hui was much smarter than her, and she couldn't even read what Shen Hui researched every day, so she never asked Shen Hui about research.

But this time, Shen Yue asked Shen Hui a question, "If the timeline cannot be observed, then sister, how do you know that this is the 26th timeline?"

Shen Yue knew that as long as she asked questions, Shen Hui would definitely answer them, so she seldom asked Shen Hui questions, she was afraid that she would know things that she shouldn't know, and then she would lose what she gained from being around Shen Hui The last warmth.

But now, she especially wanted to know one question, so she asked, "If this is the 26th timeline, are we also like this in the previous timeline?"

"No." Shen Hui replied, "This is the first time I met you. In the previous 25 timelines, I have never escaped before the age of 25, nor have I returned to Shen's house."

Shen Yue breathed a sigh of relief when she heard this answer, she hoped that the encounter between herself and Shen Hui belonged to the memory shared by both of them, instead of one party constantly suffering from the pain of memories while the other party knew nothing about it.

Having beautiful memories alone is too cruel for the person who remembers.

"Sister, do we look like our destiny?"

"Well, a little bit."

"It's as if you overwrote time 25 times just for this one time we met. Hmmmmmmmmmmmmmm..."

"This is indeed very similar to the theory of established destiny, but the person who covered the timeline 25 times is not me, but another person." When Shen Hui mentioned another person, her expression was very complicated. Shen Yue had never been in Shen Hui's place. I've seen that look on my face.

She was even more curious.

"Sister, you just said that the timeline cannot be observed. If you are not the one covering the timeline, how do you know that it is the 26th line?"

After Shen Yue asked this question, Shen Hui told her about the theory of time regression.

It was a bit complicated, but Shen Hui explained it very carefully, without using any profound theories, but using established facts as examples, which made Shen Yue understand what the so-called time travel is.

According to special relativity, the faster an entity with mass moves, the higher the total energy it contains.

Just like the relativistic momentum, as the speed of the particle soars and approaches the speed of light, its relativistic energy will increase exponentially until it approaches infinity.

This will lead to a conclusion that in order to accelerate a particle with mass to the speed of light c, there must be an infinite amount of energy to support it, which is obviously impossible.

However, about 100 years ago, a scientist discovered a substance and accidentally discovered that this substance can carry spiritual energy. Using this medium-like substance, the spiritual energy can be accelerated beyond the speed of light.

This is the space-time medium that Shen Hui uses now.

When a person dies, a huge burst of spiritual energy will erupt, and the spiritual energy can be transmitted to the past and future through the medium of time and space.

But it is meaningless to transmit spiritual energy to the future, because at the moment of death, the future no longer has a container that can receive spiritual energy. If you go to the future, there are only two results. One is to merge into other people's bodies and be absorbed by this body. The original mental energy is suppressed, and the second is to dissipate directly.

Passing it to the past can serve as a reminder to the past self.

And spiritual energy, which can also be said to be memory information, has a limit to be transmitted to the past, and the limit is the capacity of the human brain.

A person's brain volume is different in different periods. If the brain volume in a certain period is not enough to receive spiritual energy, it will cause side effects such as deep sleep, absent mindedness, mental laxity, and memory confusion at that time.

This side effect tends to appear when overlaying over a period of more than 10 years.

This kind of coverage is called linear coverage.

In addition to linear coverage, there is also a point coverage.

"The advantage of point-based coverage is that it only transmits information for a very short time, such as 1 minute, such as half an hour. This short-term mental energy will not cause too much burden on the brain, and it can be repeated many times."

"You just asked me why I can know that we are now on the 26th line when the world line has not been observed. This is related to the theory I just mentioned.

The timeline will not disappear, it is just covered. Ordinary people don’t feel that the timeline is covered, because they have never had memories of other timelines. For them, the current memory is the only memory, the only timeline.

But I am different. I have retraced at different points in different timelines. As long as I reach that point, I can remember what I did backtracking on the timeline before, and I can infer from it.

When I was 12 years old, the world lines were the second, third, and fourth. When I was 13, the timeline became the fifth and sixth. When I was 15, the timeline It is the tenth article, No.11 article, until the day we met, that is, when I was 20 years old, the timeline was the 26th article, until now, it is still the 26th article.

For people like you who have been living on only one line, you can actually tell whether a person has timeline coverage.Take me as an example. If my behavior suddenly changes for a moment and becomes inconsistent with the previous progress logic, then I have received future information and I need to prepare for time coverage. "

Shen Yue asked again, "Will there be more than 26 timelines now, maybe you will find out that this is the 27th timeline in a few years?"

Shen Hui shook his head and said affirmatively, "No, because the brain capacity of the person who went back to the entire timeline is no longer enough. Every time he goes back, the time is approaching. The 26th time is his last time. He is now No medium can go back and make a difference."

Shen Yue half understood, "Why?"

"Because, the media is still in my hands."
