Chapter 30 The conversation was very pleasant

"What are you going to do when you come back? Since you haven't found a job, you can come to our research center, and people like you who are proficient in quantum mechanics are exactly what we need. Huang Weixuan said.

"I haven't thought about it either, so I'll rest for a while, and I still want to continue my previous direction, the study of quantum phenomena in macroscopic objects." Ling Moyu said.

"A lot of people didn't understand your research back then, and after a few years, not many people still understand whether it would be difficult to consider changing directions and persistently doing it. Depending on your ability, you can change the mainstream research direction at will, and you will already be famous. I know that your purpose in doing this research is to reconcile the contradictions between quantum mechanics and general relativity, but I don't think it's time yet, and we've discussed before that if there really is a fifth force, then all attempts to reconcile the two pillars of modern science until the fifth force is discovered will be futile. Perhaps this fifth force is the medium through which the two are reconciled, but the two cannot communicate until they are discovered. Huang Weixuan said earnestly.

Of course, Ling Moyu knew that what Huang Weixuan said was right, and he was very grateful for his honesty and concern, but he was a very persistent person, and he would go on firmly what he had determined, and he was not a stubborn person to the end, as long as he confirmed that it didn't work, he would be flexible.

From a point of view, is the world randomly distributed or does it evolve along a definite path? This is a difficult problem that plagues physics, and it also makes Ling Moyu deeply confused, in the common sense of ordinary people, the existence of this world has a definite direction. If you are given a seed that can bear the desired fruit under the right conditions, you have planted a watermelon seed, and when it is ripe, it turns out to be a nest of black snakes that wriggle from under the skin!

The real world has never encountered such a thing, everything is business as usual, but the quantum world is playing out something more terrifying than a watermelon turning into a snake every moment, which happens in everyone's body. Schrödinger's cat is both alive and dead, so are we alive or dead? Life and death are a matter of life and death in itself!

Quantum mechanics is like a ghostly existence, and one of the incomprehensible places is that in quantum mechanics, there is a magical state between particles called "entangled state", assuming that when two particles enter or form an entangled state, no matter how far away the two particles are from each other, as long as the state of one of the particles is changed, the other will also change instantaneously, and the speed of transmission in this state is faster than the speed of light.

This is in line with the premise or premise of Einstein's theory of relativity: the speed of light is the limit of speed in the universe. Contradictory! So Einstein has been trying to unify the theory of relativity and quantum mechanics, and he called this unified theory "God's Reason". Moreover, the quantum mechanical system is very different from the conventional classical mechanical system established by Newton in terms of system and logic. In Newtonian mechanics, any physical quantity in the universe can be deduced and predicted through physical formulas as long as it knows its current state, which tells us that the universe is determined! Completely under the absolute constraints of the laws of physics! But Heisenberg's principle of uncertainty in quantum physics tells us that if you want to measure the position of a particle and its velocity, you can emit light quanta at that particle, and you can determine the position of the particle between the two peaks of light.

If the wavelength of the light is longer, the greater the measurement error, in order to measure the position of the particle more accurately, you can only emit a beam with a higher frequency, but the higher the frequency means the stronger the energy of the beam, the stronger the interference of the light quantum on the speed of the particle, and its perturbation will change the speed of the particle, this principle tells us: when you try to determine the position of the particle more accurately, its speed will be more inaccurate! Vice versa! It is for this reason that quantum mechanics does not calculate the exact information of a particle, but measures and calculates it through possibilities. In other words, everything in the universe is based on the strict mathematical foundation of "probability". This is contrary to Einstein's philosophy and the philosophy of ordinary people's thinking, who was more inclined to Newton's cosmology! That is, everything is decided, so Albert Einstein once said, "God never rolls dice!" ”

The macro and the micro seem to be fundamentally different, there is an insurmountable gap, it seems to belong to two different worlds, one is sunny and everything is in order, there will be no mistakes; The other is dark and obscure, full of unpredictability, anything can happen, and if you are not careful, you will fall into hell and cannot extricate yourself.

However, these two worlds turned out to be a whole, unified and harmonious, without distinguishing from each other, and there was no trace of discord in sight. Then there must be a mysterious mechanism or a huge force behind it that controls everything, "nature and the laws of nature are hidden in the vast night" It seems that Newton did not really unveil the night, and the truth may be even more terrifying!

Whatever the truth is, it must be revealed, even if it breaks me to pieces, and the truth may be the beginning of a new hope, a whole new world is calling.

Ling Moyu is an idealist with a strong sense of fate, once he feels called, he will go on without hesitation. As for the result is not something he likes, the process is more important.

"Wei Xuan, thank you for your kindness, some things have to be done, and if I don't go, others will go. I believe that this is meaningful, our job is to try and make mistakes, even if it is wrong, tell people that this path does not work, and then find another way, don't waste time on this road, this is what I think means. Ling Moyu said.

"You are still the same you, you haven't changed at all, there are always surprises, don't change your original intention!" Huang Weixuan said with a smile.

"I heard that the particle accelerator center is also in need of someone who is engaged in quantum mechanics, go to the idea that suits you, I have a friend who works there, you can try it." Huang Weixuan continued.

"I want to make up for the latest achievements in the quantum field in the past few years, the world is changing so fast, I haven't been in the industry for a few years, I'm about to become illiterate, in case I show timidity during the interview, I will be embarrassed for you." Ling Moyu said with a smile.

"Haha, don't look at it, your level is not the same as crushing them! To be honest, there have been no decent and eye-catching papers in recent years, and it is difficult to produce good papers in a short period of time for cutting-edge research like this. Theoretical breakthroughs are hard to achieve, experiments are becoming more and more difficult, larger accelerators and long waits are needed, and some people struggle to produce anything in their lifetimes. Huang Weixuan said.

"It's a big deal to leave some useful data for future generations, and the data accumulation to a certain extent may produce results, nothing more than to make a wedding dress for future generations, or someone has to do it! Doing something meaningful is second to whether it is good for the individual. Ling Moyu thought very clearly.

"Sure enough, you are a person who has seen life and death, you are still so young to see through everything, you speak like an old man, I don't have to fight for life like you." Huang Weixuan said.
