At 5:48 p.m. Beijing time on October 4, 2022, the 2022 "Nobel Prize in Physics" was announced.

Honors from Alain Aspect, John F. Clauser, and Anton Zeilinger.

In recognition of their experiments on entangled photons, demonstrating a violation of Bell's inequality and groundbreaking quantum information science.

This is called "quantum entanglement"

The award for this theory can be said to be in opposition to Einstein's theory.

So as a science fiction fan, and as the author of a science fiction novel, it is necessary to give readers a science popularization of science in real life.

I will use the most popular language to popularize the general content of this award for everyone.

First, the main work of these three people is to prove that quantum entanglement does exist. (Their work was completed between 1976 and 1997, only now that the award is being awarded to them.)

Second, explain the divergence between quantum entanglement and Einstein's theory.

You have two balls, red and black

You pack them into two boxes blindfolded, one by your side and the other anywhere away.

If you find a red ball from the box next to you, the other box must be a black ball, and vice versa.

It's easy to understand at this point.

But the next thing is interesting.

Albert Einstein believed that the ball in a distant box is determined when you put it in blindfolded.

Quantum mechanics believes that after you put the ball into the box blindfolded, the balls in the box are in a superposition state, and the balls in the box next to you, before you take them out, are in a superposition state that is both red and black, which sounds very mysterious.

(Here you can first learn about Schrödinger's cat theory)

Only when you take the ball out of the box can you determine what ball is in the box, and at the same time, what ball is in the box in the distance is fixed in an instant.

Einstein felt that this transmission of information faster than the speed of light was unreasonable.

But in fact, this answer, which is closer to metaphysics, is only true in today's quantum realm.

So, the human brain is a finite drop, and the worldview we know is only a small part.

In this novel, Liu Yi was talking to an eternal voice in the universe before, and I mentioned this sentence in that chapter

"Science is an adventure for humanity, an adventure that consists in exploring ways of thinking about the world, and in being ready to subvert some of the definite understandings we have so far held."

Human civilization has been exploring and evolving step by step, and there has never been an eternal truth in the world, so if we look at science with awe and science, we will become more and more active in human development.
