Augustine's question made Reiner laugh dumbly.

It's not that he wants to mock the other party or anything, but Reiner has some emotion, no matter what world he is in, the same problem will actually appear.

Seeing Reiner's strange expression, Augustine was a little gloomy, and he continued to ask.

"Planets like the moon are made of rocks, and rocks are made of elemental compounds, and these elements are essentially microscopic particles, and if quantum effects really exist, then these microscopic particles should also be in a state of probability distribution, in other words, if there is a certain situation, when everyone does not observe the moon, the microscopic particles that make up the moon will turn back into probability clouds, and the next time I look at it, the moon may fall apart, can I understand this?"

Augustine's theory made several mages in the audience in deep thought, although Reiner said that since some theories are only true at macroscopic low speeds, it is natural that there are theories that can only be true at microscopic high speeds, and quantum theories are obviously only observable in the microscopic realm.

But Augustine's statement has drawn people's attention to one thing, that is, macroscopic objects are made of microscopic particles, so why does the microscopic effect not affect the macroscopic world, if there is really such a dividing line between microcosm and macrocosm, what is this?

In fact, many people also find that the dividing line between macro and micro is not clear, and people cannot distinguish whether something belongs to macro or micro, so it is difficult to distinguish between Reiner's criterion.

"Quantum effects exist for a system made up of individual microscopic particles, but for a macroscopic system like the moon, quantum effects do not exist, at least not in our current observations."

Reiner paused, then continued.

"I'm sure you've noticed that my description of the probability cloud is a wave function, and it is precisely because the particles embody considerable volatility that it leads to the emergence of various singular phenomena, so if we really want to find a simple way to distinguish it, I think it should be the problem we are studying and the corresponding object Ian Gray wave size, in short, the category of whether the object exhibits obvious fluctuations."

Seeing that some of the mages hadn't reacted yet, Reiner explained.

"For example, if we want to study the operation process of a planet, the size of the Ian Gray wave corresponding to this planet is extremely small, so it naturally does not show waves, but if we study an electron crossing a double slit, then the size of the Ian Gray wave corresponding to the electron is close to the double slit, and the electron shows a wave nature, so we need to take into account the quantum effect."

He stood up and simply sketched out some calculations in mid-air.

"To explain the question mathematically of His Excellency Augustine, if we assume that the probability of a particle appearing here is X, following the probability distribution of its wave function, then for a macroscopic object, it contains nearly infinite particles, then the probability of this macroscopic object appearing here is the product of positive infinity and X, of course, this is not an actual quantum process, I want to explain that the probability of the moon in the sky is infinitely close to 1 even if quantum theory is applied, therefore, The quantum effects of macroscopic objects can be considered non-existent. ”

Hearing Reiner's explanation, Augustine reluctantly accepted, he closed his eyes, and motioned for Reiner to continue.

"Wait a minute, Reiner."

At this moment, Lord Braggs suddenly spoke, causing everyone's nerves to tense again.

"I still have a question, if we design a magic circle with a quantum system, such as an atom that can decay, this system presents two possibilities, one is the atomic decay and releases a particle, and the other is not decay and does not release particles."

Lord Braggs said, and with a movement of his fingers, a box of light appeared on the table in front of him.

"If the quantum system releases a particle, then the particle will trigger a poison gas device, so that the box is full of poison gas, and in the box, there is a kitten, and if the gas spreads, it will die."

In the box made of light, a mimicry kitten appeared, licking its paws smartly, innocent.

"The problem is this, a quantum system may release a particle to kill the kitten, or it may not, the kitten is safe, and if we make observations, then the wave function of the quantum system composed of atoms that may decay will collapse because of the observation, and the kittens will either die or live, but the question is, what if we don't observe?"

His Excellency Braggs' words did not cause any stir at first, but soon, His Excellency Alberton was suddenly startled, his face became solemn, and he immediately spoke.

"If no observation is made, then whether the atom decays is only a probability representation, and the life and death of the cat, that is, a probability, according to the assumption of quantum theory, the cat should be in a superposition of life and death at the moment, and once the observation is made, the wave function of the quantum system will collapse immediately, and the life and death of the cat will be determined at the moment of opening the box!"

"How can this be !?"

Regens immediately stood up, because it was completely contrary to logical thinking, like tossing a coin, although it was also a probability event, but people knew that the landed coin could only be one of heads or tails, and this was something that was already decided when it landed.

But at this moment, the cat of Lord Braggs shows people such a scene, as long as the box is closed, the cat will be in a state of quantum superposition, in a state of superposition of life and death, but once the box is opened, the life and death of the cat will be determined in an instant with the collapse of the wave function!

Lord Braggs's hypothesis is extremely cunning, because Reiner said that quantum effects only exist in the microscopic scale, and the life and death of the cat is obviously a macroscopic event, and the cat of Lord Braggs, which combines the microscopic quantum system with the macroscopic life and death of the cat, can be said to be an advanced version of whether the moon exists as a result of observations that Augustine just mentioned.

In this hypothesis, Lord Braggs transferred the quantum effects of the microscopic system to the macroscopic system through an ingenious method, so that the macroscopic system also had quantum effects.

If you accept quantum theory, then you must accept this half-immortal cat, and if you do not accept the state of superposition of life and death of this cat, then it is equivalent to not accepting quantum theory.

At the same time, the macroscopic quantum effects exhibited by the cat are also a huge question for Reiner's many explanations.

After understanding Lord Braggs's thought experiment, everyone subconsciously looked at Reiner.

They are seeking explanations.
