Why can neutrinos go back to the past at the speed of light and make time machines? "

What do you mean by breaking the speed of light? (Reprinted by: Li Jianmang)

On September 23rd, when I saw this amazing news, I was amazed at Weibo of Sina and Tencent.

"CERN, a large physics laboratory in Switzerland, may have completely shattered modern physics. The information came out yesterday. They may have found a neutrino that runs faster than light. If this experimental result is finally confirmed, the foundation of modern physics will collapse. The basis of modern physics is that the speed of light is the fastest in the universe. This law was established by Einstein in his special theory of relativity. 』

The reader only deserves to call the pig exclaim "super news!" Other readers don't seem to realize what this news will mean once it is confirmed to be true!

Last night, when my son came home, I went to the railway station to meet him. As soon as he got on the bus, the first thing he asked me was "Did you hear the news?" I am stupefied. I just want to ask which news. I immediately realized that it was the news of this CERN. My son, who studies astrophysics, said Utrecht University was "exploded". People discuss and debate this problem every day. The son "announced" in class: "If we spent so much money on learning garbage, should we refund the money?" , everyone burst into laughter!

Yes! The news is explosive. Many people think that this experiment will be proved wrong in the end, including Hawking in Britain, who denies the possibility that this experiment is correct. My knowledge of physics has long prevented me from making a wrong judgment on this experiment. I just want to talk about why people are so afraid, and what it means if this experiment is correct.

It means that the famous mass-energy conversion formula (Lorentz formula) is wrong, that Einstein's two theories of relativity are wrong, that quantum theory is wrong, and that the whole modern physics is wrong. But this is not the most explosive. The biggest explosion is that it will challenge our whole human way of thinking; Between all things, the causal relationship cannot be reversed! Or we can't see the effect first, then the reason, and the time relationship is reversed. This is our human way of thinking and the basis of logic. If this axiom is broken, all human knowledge will be challenged!

Why does breaking the speed of light cause causal reversal? To this end, I will design an imaginary situation similar to Einstein's assumption that the speed of light is constant; Suppose there is a star outside the earth, moving faster than the speed of light towards the earth. At an earlier time T0, when it passed the position P0, P0 sent a beam of light to the earth, and it ran for a while. Later, when it passed the position P 1, P 1 sent another beam of light to the earth. Excuse me; Does the light emitted by P0 at time T0 reach the earth first, or does the light emitted by T 1 time P 1 reach the earth first?

The answer is obvious; Because the star travels faster than the speed of light, when the star passes through P 1, the light emitted by P0 is already behind the star. Then the light that reaches the earth first must be the light from T 1 time P 1. What does this mean? This means that we first see the light that comes out later, and then we see the light that comes out earlier. Our observation caused a causal reversal of time!

This is the explosive power of this news! Once proved to be correct, it will destroy all our knowledge systems and the foundation of our way of thinking. In particular, it will destroy the foundation of the whole science, because "observation" has become an unreliable cognitive way! Once this concept becomes a reality, wow, the world knowledge field is exploding. Strangely enough; China people don't seem to care. It can be seen that knowledge is not important in China.
