My girlfriend died in the past

Chapter 167 An Lan's Diary
Zhuang Xiao took out the stack of documents carefully for fear of damaging them.

But these materials seemed to have been specially processed, so there was no problem. The paper was still as white as new, without even a trace of yellowing.

Zhuang Xiao looked inside the safe carefully again and saw that there was nothing inside except the pile of documents. He then felt relieved and decided to look through it.

He picked up the top one at random, and couldn't help but raise his eyebrows when he saw the words printed in Microsoft Yahei font on the cover.

"On the Feasibility of Time and Space Travel".

This title is very embarrassing.

He now understood what Shu Die said about why the group gave up investing.

I guess Shu Mingyu's father, the former head of Shushi Group, must have been sweating when he saw this title.

People originally wanted to invest in scientific and technological research, but who knew you would go and study metaphysics!

But after being nervous for a while, Zhuang Xiao immediately became serious.

Because he himself successfully achieved "time travel back".

This shows that this is indeed scientific.

So he opened it and began to study.

The wording used at the beginning is relatively easy to understand. This is probably intended to be shown to investors when bidding for investment and sponsorship, so no professional terms are used.

To put it simply, the above describes An Lan’s two research directions.

First, the physical body travels through time.

An Lan wants to figure out a way to travel through time physically, but it is not possible for the physical body to travel through time.

It’s the same old saying, “Grandfather Paradox”.

This is simply unsolvable.

In fact, there have been too many similar scenes in film and television dramas.

Even if it can be done, two conditions must be met.

First of all, you cannot let your original self see your own face.

Secondly, that is to say, you think you have changed the past, but in fact the past has not changed.

For example, the TV series "The Legend of Sword and Fairy 1".

Li Xiaoyao thought that by flying Zhao Linger in the opposite direction he could change the tragedy of the past.

As the earth is round, they flew on the phoenix for a long time before finally arriving at the Fairy Island.

This is the kind of thing that no matter how hard you try, it is actually part of the "past" and "history."

That’s right, including the thoughts and behaviors you want to change when you go back to the past, they are also part of the existing “past” and “history”.

Or there can only be a parallel world.

That is, when you go back to the past, new developments will create a new parallel world.

The two worlds do not affect each other.

The classics among the classics are the comics of Marvel and DC, as well as Big Trunks in "Dragon Ball".

An Lan’s first research is how to find a parallel world and then find ways to go to that parallel world.

Zhuang Xiao couldn't help but look back.

But it ended after just a few pages.

He glanced at the time and place marked in the lower right corner.

【1952, Massachusetts Institute of Technology, Cambridge, Massachusetts. 】

"Ok?"

Zhuang Xiao raised his eyebrows. This was actually written in 1952?
If he remembered correctly, An Lan was born in 1940 and returned to China in 1960.

So this means that this was written when she was still in the United States?
She was only twelve years old that year!

But there's something strange here.

Because Zhuang Xiao remembered that after An Lan returned to China, he led the research and development of domestic computers.

But it seems like she started theoretical research on time-space travel before returning to China?
Zhuang Xiao always thought that she started studying time and space after she became successful, but it turns out that she had already started before returning to China.
So, this thing is not actually used to attract sponsorship.

In other words, sponsorship was not sought domestically.

This should be because she tried to get sponsorship at MIT when she was twelve years old, but it obviously failed, so she gave up temporarily and returned to China a few years later.

So why give up?

Zhuang Xiao wanted to continue reading, but this part was only a few thin pages.

So he picked up the second document.

This seems to be something like a diary.

Because not only is there a date on it, but it also uses the first-person perspective.

【XNUM X Year X NUM X Month X NUM X Day】

[No one was willing to sponsor me. I also consulted my teacher, who was not optimistic about this research. He thought I was on the wrong track, but he was still willing to take me to Einstein and Oppenheimer for consultation.]

[Einstein was very interested in this, but he thought that maybe I was going in the wrong direction. Unfortunately, he had started to get sick and was quite powerless on a daily basis, so it wouldn't be of much help.]

[Oppenheimer was taciturn and had no interest in this. Moreover, his security clearance was revoked this year. In addition, due to the rampant McCarthyism, he was reluctant to contact a Chinese like me, so this path was not feasible.]

[But it doesn’t matter. I never thought of relying on others. I can walk this path on my own.]

【XNUM X Year X NUM X Month X NUM X Day】

[Why?! All theories have proven that parallel worlds most likely do not exist, or even if they do exist, we cannot discover them, so it is impossible to travel through parallel worlds!]

【Maybe I should give up. 】

【My motherland needs me. Maybe it’s time to go home. 】

【XNUM X Year X NUM X Month X NUM X Day】

[Still hopeless, I gave up my research on parallel worlds. ]

[But I won't give up. It's just right. Since it has been proven that parallel worlds may not exist, or that there is no way to reach parallel worlds, then we have to find a way to go back to the past.]

[In fact, going back to the past is real, but as far as I know, in most cases, in order to avoid time paradoxes, one must either correct everything according to history, that is, not change past history, or make oneself a part of history.]

[In other words, one must find a way to project one's consciousness onto one's past self, which can be considered a disguised way of "going back to the past" without triggering a paradox.]

[But the question that arises from this is, since the future has been changed, does the original future still exist? If it does not exist, will my memory change? But if the memory changes, how can I go back to the past? ]

[But this is a very good topic and research direction. I can start researching it when I return to China and settle down. The atmosphere here is getting more and more wrong. I can’t stay here any longer.]

【XNUM X Year X NUM X Month X NUM X Day】

[The comrades over there have been contacted. They said they would find a time for me to return, but my safety is the first priority, nothing else matters.]

[A comrade died]

[Finally I can go back to China. Comrades asked me what I should bring with me. I don’t need anything, just my research notebooks.]

【XNUM X Year X NUM X Month X NUM X Day】

[It feels so good to be back in my motherland. Although my motherland is indeed poor, I know that the future is on our side.]

【XNUM X Year X NUM X Month X NUM X Day】

【I changed history.】
