What will be seen if people can reach the speed of light?The color of the world will become different

Why can we see this colorful world? Because of light.

The reason why we can see things is essentially the result of light that irradiated on the object and reflected into our eyes. For example, we can't see the situation in the black hole vision, because within the black hole vision, the speed of escape exceeds the speed of light, and the light entering the black hole vision cannot come out again, so it naturally becomes there. An invisible world. Light is composed of photons, and photons, as the basic particles, are objective substances. Because there is no static quality, light has the fastest speed in the universe, that is, 299792458 meters per second. The speed of light. Although we have no way to catch up in the real world, in the world of thought, there is nothing to stop us, so a very interesting problem arises.

If we have the speed of moving equal to light, how will the world we see?

We live in a macro -low -speed world. From our common sense, if we move forward at the speed of light, the world we see will not change, because moving forward at the speed of light is only Just enter our eyes. And when we retreat at the speed of light, the situation is completely different, and the light from front will never catch up with us, so we can see nothing. Is this really the case? No, this sounds reasonable, but it is completely based on the conclusions of common sense in macro -low -speed environments. The fact is not like this. When it comes to exercise speed, we always need to choose a reference system. So what is the reference of the speed of light?

We kicked a football forward, and the ball flew forward at a rate of 5 meters per second. The "5 meters per second" here obviously used us as a reference department.

So is light using the light source as the reference system? It seems that this is the case, but this is not the case.在宇宙中存在着很多双星系统，它们是由两颗相互绕行的发光恒星所组成的，在我们的视角来看，这两颗相互绕行的恒星总是有一颗在离我们远去，而The other is running towards us. If the speed of light is based on the light source, the speed of the two stars in the two stars in the double star system will continue to change, so in our opinion, the winding track of the double star system should also be constantly deformed, but in fact The situation is that these tracks are very stable and have not changed.

Therefore, light does not use the light source as the reference system. In this regard, Einstein has boldly assumed that the speed of light is not for a single reference system. Compared Mi, constant.

It can be seen that even if our speed reaches the speed of light, light is compared to us, and its speed is still 299792458 meters per second. No matter whether we go forward or back, everything we see will not change, let alone appear. There was a dark situation in front of the high speed. However, if people can really move at the speed of light, the world they see will not change at all, at least in terms of color.

Most people have heard the whistle of the train. Maybe you have noticed this phenomenon, that is, when the train comes from the same distance, the flute sounds more loud, and the train to the distance is. Low sinking.

Why is this? The sound is passed in the form of sound waves. Since it is a wave, it has three attributes, namely wave speed, wavelength and frequency. When the train comes to us, the sound waves generated by the whistle will be squeezed by the moving train, so the wavelength becomes shorter, but the wavelength of the sound waves remains unchanged, so the wavelength is shorter, and the frequency will increase frequently. This makes the sound of flute changes when entering our ears. When the train is driving away from us, the situation is exactly the opposite. This is the internal reason that the flute sounds are different when the train comes. This was discovered by Austrian physicist Doppler, so it is also called Doppler effect.

Light has a two -phenomena, that is to say, light is waves and particles.

Since the light is waved, it naturally follows the Doppler effect, so when we move forward at a speed of light, the wavelength of light will be compressed, and different wavelengths represent different colors of light. The shorter the wavelength, the more light, the light, the light, the light, the light, the light, the light, and the light. The closer to purple, the more the world in front of us will be purple. This phenomenon is also called "blue movement". Conversely, if we retreat at the speed of light, the wavelength of light will be stretched. The longer the wavelength, the closer the light will be red, so the world in front of us will become red. This phenomenon will be called it. It is "red shift". Of course, this means that our speed is still in a controllable range. If our movement speed can still be increased infinitely, then we may really see nothing, because the wavelength is too short or too long, it will exceed the visible light, and it will exceed visible light. Scope.
