Light is a physical quantity that we are often exposed to in our lives, so we can draw more conclusions. The first few times, we talked about shadows. This time, let's talk about lighting. Actually, there is nothing about the lights. I just thought about why the light can't reach 100 million meters away, isn't the speed of light 100 million meters per second? However, in life, the light does not even shine at a distance of a thousand meters. This obviously violates the laws of physics, huh? The speed of light is 100 million meters, and the light is already a second after it is illuminated for a long time. However, the light can only reach a range of a few meters. So, what do you think is the reason? Mizukawa said.

Photons cannot move independently and must be inside the beam. The speed of the beam is much slower. As a result, it is not possible to irradiate long distances. You may think it's too simple, so I'll explain why the photon is inside the beam. This is because the rest mass of the photon is zero, and this state is extremely unstable. Why? What does zero stand for, no. Doesn't having zero rest mass mean that there is no mass? That's the case, it's not like that. It is true that zero means no. However, zero rest mass here is a split-second thing. In this instantaneous time, there is actually quality. That's right, you don't feel right. Since it is zero, how can there be a rest mass? The answer is simple, photons are in a state of contradiction. That is, there is a paradox. In order for the paradox to disappear, the photon can only move. However, a large number of photons have to get rid of this paradox. Therefore, in order to avoid collisions between photons, the photons are naturally bound by the light source with a beam. Liuzifeng said that it was a bit mysterious, but no one objected.

Liuzifeng came to mention the beam, and it was the crux of the matter. You notice that the closer you get to the light source, the darker the beam becomes. The reason why we can't see the light going far away is because the beam is so scattered. In fact, the beam reaches a distance of 100 million meters, but it is not visible to the naked eye. There is a physical quantity involved here, which is brightness. The beams in the distance are so low that we can't see them.

Duenias, you say the beam is too scattered. Well, that's all. So, isn't there a gradual trend of brightness? However, I did not see this phenomenon in my actual observations. Instead, the beam is suddenly gone. In my opinion, it's not a matter of beam dispersion. The photon gains enough energy as it moves inside the beam, and then the photon escapes from the beam. Then, it is absorbed by the objects it encounters. Now that the photons have escaped, it is naturally impossible for the beam to shine far.

Margarita, I think there's a problem. The velocity of a photon is 100 million meters per second, and the energy photon that escapes the beam cannot be obtained in one second? Could it be that there is a lot of energy in the beam?

Don't look at the light as an ordinary thing, but it has a lot of energy. In general, most of an object's energy is not released when it disappears. However, that doesn't mean that these energies don't exist. The speed of light says that the energy of the yin lamp is beyond our imagination. And in one lamp there may be the secrets of the whole universe.

I had an idea if we could keep emitting photons from object to object and we could absorb all the photons. In this way, a lot of energy can be obtained. ……。
