Is the fastest thing to be a fast child? What is Tachyon?

Yes, it's light. According to the principle of relativity, the speed of light is the limit of speed, and space-time can be distorted but not broken, so at the current level of scientific development, it is still believed that the speed of light is the fastest.

Here are some narratives about the speed of light, I read the article here after seeing your question, but I think their theory is not yet mature, and it is basically still in the hypothetical stage, if the building manager is interested, you can take a look. I won't copy them to take up space, so I'll keep it**.

Hehe, the comrades downstairs have already stayed first, so please ask the building manager to take a look downstairs.

As for what tachyon is, I've read some reports about it, and it's actually a theoretical model that hasn't been discovered in the real world, and even if it does, it can't be discovered by existing technology. If we want to prove its existence, then the existing scientific and technological technologies and theories cannot be reached, and a new system of physical theories must be studied in this system.

Keep up the good work, and I hope you can become the next Einstein.

Particles of matter moving at a speed lower than the speed of light cannot travel faster than the speed of light, but it cannot be ruled out that there is motion in nature.

Particles that move faster than the speed of light, people call these particles tachyons, and if there are tachyons, Einstein's theory of relativity is not right!!

Personally, I think it should be the fastest speed of light

Because no one can say that Einstein's theory of relativity is wrong!!

Besides, tachyon has not been proven experimentally!!

What are you copying me on the 13th floor!!

I read the newspaper the other day, and there is a country (it seems to be Sweden, right?) The photons were successfully accelerated in the laboratory, and thus a faster speed than the speed of light was obtained. So it should be possible to find a faster speed of movement of matter than the speed of light in nature.

The fastest is the ,.. of thoughtThe speed of light is not something we still think of ourselves.

What you said is contrary to current science, ions are composed of electrons, protons, and neutrons. In a world of these particles, nothing can be faster than electromagnetic waves.

Tachyon is also known as tachyon.

The following ** has a detailed introduction.

A photon, if something is faster than the speed of light, it is bound by time. Foundations of the theory of relativity.

It's light. If there is something faster than light. It's already a sensation.

Theoretically, the speed of a tachyon can be faster than the speed of light.

Einstein's theory of relativity proposed that there could be no faster than the speed of light.

Things will come to a conclusion one day. Someday. There will be people who will discover something faster than light. Read so many answers above. I just want to say.

There are things that are faster than the speed of light. But I don't know what. If only I knew. I wouldn't be sitting here.

For now, it's still the speed of light.

I don't know what a fast chopstick is, but I do know what chopsticks are.

I'm not afraid that I can't do it, I'm just afraid that I can't think of it

Although I don't know yet.

But if you work hard, you'll find the problem.

Break the mold

Tachyons are tachyons. We all know that Einstein's theory of relativity states that there is no matter in the world that can move faster than the speed of light. Does that mean that the tachyon does not exist at all, and that the tachyon violates the theory of relativity?

In fact, Einstein's theory of relativity proposes that matter with mass and information cannot move faster than the speed of light.

Einstein's theory of relativity does not qualify this, suggesting that tachyon particles are possible.

Then the core question arises again, what can be done in the world without quality and information?

The expansion of the universe is a phenomenon without mass and information, because the space is expanding, the light waves emitted by the celestial bodies are elongated, the frequency decreases, and the spectral lines "turn red", which is called the cosmological redshift, and we know that the farther away the body, the greater the redshift. On a cosmic scale, the expansion rate of the universe is considered to be faster than the speed of light.
