Chapter 528

According to the classical magic system, the most important criterion to judge whether a theory is correct is whether the theory itself is self consistent and whether it can well explain the experimental rules. Even if the theory violates human intuition or some deep-rooted viewpoints in cognition, only if it can meet these two points, then the mages can accept the theory.

For example, Lena first overturned the theory of the four elements of earth, water, wind and fire, and then put forward the idea of coexistence of multiple elements. Although this new idea had a considerable impact on the alchemy system in the past few hundred years, it was verified by experiments that Lena's theory was correct, so the mages began to gradually accept such a theory.

Another example is quantum theory. Although it has gone beyond the scope of common sense and fundamentally subverted people's cognitive world, it has successfully explained the experimental phenomenon, so it is acceptable.

Legendary mages such as Mr. Braggs and Mr. Alberton set two conditions to test whether a theory is successful.

The first is that the magic theory must be correct, which is actually the degree to which the prediction of the magic theory conforms to the experimental results. The more accurate the theory can describe the experiment, the more correct the theory tends to be.

The second is that the theory of magic must give a complete description. This simple understanding is that every actual element of magic must have its corresponding element in the theory of magic, that is, a complete theory of magic must be able to accurately describe every element of magic.

For quantum theory, the first condition seems to have passed. Quantum theory can successfully predict many abnormal phenomena of microscopic particles and give solutions.

But the second condition contradicts quantum theory.

First of all, according to the Ian gray uncertainty principle, mages can never accurately measure the position and momentum of a micro particle at the same time, which violates the completeness criterion.

Secondly, according to the description of general relativity, the speed of light is the limit of speed, and the transmission of any event and information can not exceed the speed of light. However, in quantum theory, the state of two entangled quanta can be determined, that is, observing the spin state of one quantum can confirm the spin state of the other quantum, and this confirmation ignores the distance.

"In a quantum system with zero total spin, if the spin of one particle is a certain value, then the spin of the other particle can be accurately calculated by this value."

Reiner repeated the results of the mages' experiments and murmured to himself.

This is the biggest challenge to quantum theory at present.

Because this kind of quantum entanglement is not limited by distance at present. To be exact, the spin state of another particle is determined by the spin state of the current particle. Mages don't even need to observe the state of another particle.

This phenomenon made mages quickly associate with Solon.

The magic resistance of Sauron alien is that as long as one Sauron alien is killed by a specific spell, the magic resistance will be transmitted to all Sauron alien almost at the same time without time, which is equivalent to the active evolution of the whole group of Sauron alien in a short time.

It's hard to understand and the biggest problem.

This means that the mages can't use some very destructive magic at will. Although it can destroy most of the incoming Sauron, once used, this kind of magic will have little effect on other Sauron in the future.

After discovering the phenomenon of quantum entanglement, the mages put forward an idea that the active evolutionary ability of Solon's alien species actually relies on quantum theory. Each Solon's alien species will have some quantum entanglement with other individuals. This entanglement is well explained. The reproduction of Solon's alien species itself is very easy to cause this phenomenon.

In the phenomenon of quantum entanglement, an individual of Solon's different species is attacked, and the state of quantum is changed at the same time, and this state can be transmitted to other individuals, so in an instant, all individuals get the information of the magic, and the corresponding measures are produced.

The mages want to analyze this phenomenon and try to find a way to fight against Sauron.

However, the property of quantum entanglement leads to the biggest problem, that is, if the distance between two particles is too long, the result of this observation will exceed the speed of light.

If the distance between two particles is one light year, according to the explanation of general relativity, it will take at least one year for the observers to know the spin state of the two particles.

But in quantum theory, the spin states of the two particles are related and entangled. As long as we know the state of one particle, we can immediately know the state of the other particle. The transmission of this information is instantaneous.

This goes against the inference in general relativity that the transmission of any information will not exceed the speed of light.

"So, depending on the phenomenon of quantum entanglement, we can make communication devices that can transfer information very fast?"

Aimiya tilted her head. She was supposed to deliver afternoon tea to Lena in the laboratory, but she found that Lena did not carry out the experiment as usual. Instead, she sat on the chair and thought about the blank blackboard. So she asked curiously. After receiving Lena's patient explanation, she thought so."In theory, it can be so, because the current communication is electromagnetic wave communication, which is limited by the speed of light. Although the magic computer has laid the communication cable, the communication delay can be ignored in the half plane that can be touched now, but if we want to go to the sea of stars in the future, this kind of communication delay must be solved."

Lena was a little surprised. He didn't expect that alimea could think of this piece so quickly. He thought alimea didn't care much about magic computer and Internet related problems.

"But, sir Bragg, what do they mean by this completeness? Every actual element of magic must, er, have its corresponding element in magic theory. What does this have to do with quantum entanglement?"

Although Emilia can barely understand the problems that Lena is talking about, she still doesn't quite understand the core of the problems that Lena is facing.

"Well, I can explain it to you with a little game."

Lena nodded. On the one hand, the reason why he explained to alimia in such detail was to make his thinking clearer.

He took out a stack of cards from his storage bag, which is a very popular game props.

"Let's simulate quantum entanglement."
