I was shocked, but at the same time it was hard to accept such a conclusion.

I originally thought that the so-called parallel universe has many worlds similar to those we are in, and each of us will have many different selves and live in different worlds, but the emergence of these parallel worlds must have very strict conditions - if it is just because you look at the puppy on the side of the road or choose a branch at the fork in the road, there will be an additional parallel world......

Don't you think that's too much child's play?!

According to this theory, then the so-called classical physics does not exist at all, and the existence of the entire universe is idealistic - the simple question is, where does energy and matter come from to create those near-infinite universes?

Is it up to you to take one more look, or walk through a fork in the road?

As if seeing my doubts, Shen Tangzhi said, "Incredible, isn't it? Then I ask you, how can you exist in front of me? Why is it not Zhang Guang, Li Guang, Wang Guang, Qian Guang, but you Jiguang? ”

I subconsciously wanted to speak, but I suddenly realized that Shen Tangzhi was asking "why can you exist in front of me", "why", not "why".

I suddenly felt that this question was very difficult to answer, it was a big proposition.

The more I thought about it, the more frightened I became, and a few drops of sweat rolled down my forehead—and I began to sweat unconsciously.

Compared with the parallel universe theory, I suddenly realized that my own existence was no less than the parallel world theory.

I'm 28 years old, which means that about 29 years ago, my dad managed to get my mom pregnant, and in turn, my grandfather gave birth to my dad and my great-grandfather gave birth to my grandpa...... All the way back to any N generations of ancestors, regardless of the severe cold of glaciers, floods and beasts, wars and chaos, hunger and barrenness in history, they can not only survive, but also have children, and always have sons, which is a very small probability.

This continuation of the direct bloodline can be traced all the way back to ancient times when human beings were born...... No, it can be traced all the way back, and apes did not suddenly evolve into man, and mammals did not suddenly leave the ocean and enter life on land, and can even be traced back to the formation of life - if there were no suitable physical constants, there would be no planets and life at all!

The gun in the quantum suicide experiment, if the gun keeps "clicking", of course, is a very small and extremely small probability, if it is n times, then the probability is 1/2^n - but my existence, why is it not a very small and extremely small probability? My engineering formula might even be 1/n^n!

What a terrible probability that is!!

But assuming the parallel universe theory is correct, then my existence is no longer a "miracle".

If I were the one sitting in front of that gun, I would only hear the "click" all I could hear in other worlds, no matter how corpses were scattered all over the place.

The prerequisite for everything is my very existence.

In fact, if you "objectively" speaking, the probability that a family has sons in n generations is extremely small, but for you and me, it is a "must", and the probability is 100%! In the same way, some people lament the ingenuity of the universe, the probability of its production is so low, but according to the principle of anthropic, the universe must be like this!

Thinking of this, I was in a cold sweat and could barely breathe.

"Looks like you've figured it out." There was not the slightest hint of playfulness in Shen Tangzhi's words, on the contrary, I even saw a hint of shock in her eyes, "So, if the parallel universe theory is correct, then for someone, he will not die no matter how he tries to commit suicide." ”

"If he wipes his neck with a knife, then because the knife is composed of a group of particles that conform to the wave equation, there is always a very, very small possibility that somehow it will penetrate the person's neck without any damage, and thus keep the person immortal. Of course, this probability is extremely small, but according to the parallel universe theory, everything that can happen actually happens, so this phenomenon will always happen in a certain universe. In fact, no matter what way you change to commit suicide, whether it is jumping off a building, lying on a rail, or hanging, there are always some universes that keep him alive. From the person's own point of view, he can't die no matter how he dies! Of course, in the infinite universes, his family and friends will mourn for him. ”

This is the strange theory that was introduced from the quantum suicide thought experiment, which is called "quantum immortality". From a subjective point of view, not only can a person never complete suicide, but in fact once he begins to exist, he will never disappear! There are always some quantum effects that make a person not age, and according to MWi, these very low probabilities always correspond to some actual world! If the multiverse theory is correct, then we get the inference that consciousness is eternal and immortal, and that once a "consciousness" begins to exist, it must be immortal from its own point of view! ”

I walked out of the Bojing Times Building with Shen Tangzhi with a very depressed mood, and then said goodbye to her.

I still have important things to do - that is, to forward the results of my discussion with Shen Tangzhi to K.

At first, I thought K was purely a madman, a cult leader-like character, but after a long conversation with Shen Tangzhi, I realized that K was not useless, at least in the realm of ideas, he (I conceived of K as a male) thought more than most people.

However, these are not excuses for him to exonerate himself, there are already 5 innocent dead, and K's words are so demagogic, if I don't bring them to justice as soon as possible, I'm afraid more victims will be discovered!

Shen Tangzhi finally told me that the inventor of the parallel universe theory, Everett himself, also believed to some extent that his "consciousness" would continue along some branch of the universe that did not lead to death.

But tragically, and ironically, his family believes in parallel universes so much that his daughter Liz says in a suicide note that she has gone to "another parallel world" to meet him.

I didn't care if the Everetts actually met in a certain world, I just felt creepy and chills in my back.

Things like "consciousness", "eternal life", too metaphysical, too tempting.

In any case, if the inventor of a theory shows signs of madness, what serious consequences will the demagogic and dangerous nature of such a theory have when propagated by people with ulterior motives like K?

At least in the world we live in now, we see that it is impossible for people to be resurrected from death.

Back in the office, I left a message for K with a strange feeling, and the content was basically some ideas about quantum immortality.

Unexpectedly, after a while, I got a reply.

In the night light, a line flashed on my laptop screen:

[Congratulations, you passed the first level, and now I will give you a reward.] I'll give you three names, and that hard drive will be in the hands of one of them. 】
