The material cannot be divided infinitely, why not be less than the length of Planck?No matter how young is the other world

A piece of paper can be cut in half, and then it can be divided again. In this way, it seems that it can be cut all the time, but it is not actually the case.

Materials cannot be divided infinitely because we do not have enough precision cutting tools, but because the material has a minimum unit, and this unit is called Planck's length. In modern physics, if a physical quantity has an inseparable minimum basic unit, then this physical quantity is quantized, and its minimum unit is called "quantum", and the minimum interval between the two quantums is called as it is called it as it is called "Planck Time" is the 10-43 square seconds of 10, and because the speed of light in the vacuum is theoretically theoretical speed, the use of Planck's time at the speed of light will get a minimum length unit, that is, that is, that is, that is, that is, that is, that is, that is, it is Planck's length, a -33 centimeters with a value of 10.

In theory, the length of Planck reaches the minimum value, and it is impossible to continue to divide.

why? In fact, this is not to say that there is absolutely no material that can be smaller than Planck's length, but in Planck's length, all existing physical laws will fail. From the perspective of scale, our world can be divided into a macro and micro world, but the macro world does not exist independently, but is closely linked. Everything that happens in the micro world will eventually reflect the macro world we are familiar with. Among them. For example, the structure of a molecule is damaged, then the cells composed of this molecule will die or mutate, and this mutant cells will cause the organs to belong to the disease. Of course, if it is just a change of a molecule, it may not cause visible effects in the macro world, but this impact itself is objective.

If the scale of the material is smaller than the length of Planck, the problem becomes different.

All physical rules applied in our world are not applicable below Planck's length, that is to say, the world under this scale is very different from the world where we live. Some changes will not affect our world. In other words, if there is a substance smaller than the length of Planck, no matter what the changes these substances have happened, it will not have any impact on our world, so for us, under the Planck scale Everything that happens is meaningless, so we can say that Planck's length in our world is the smallest unit of material.

It is worth noting that Planck's length is only the smallest unit in theory, and the actual situation is that we have never found such a small material.

At present, the smallest material unit known to be human is basic particles. The photons we are familiar with and the often hearing Quick belong to the basic particles, and the basic particles are inseparable. Speaking of unimfract, Quark is a relatively special guy. Not only can a single Quark unable to break, we can't even separate several quarks that are combined in all. Under the physical scale we are familiar with, atoms are a relatively small unit, and the atoms are composed of atomic nucleus and nuclear electrons, and the nucleus is composed of protons and neutrons. As for protons and neutrons, It is a combination of Quark, and it is usually 3 quarks.

There are four known basic forces in the world of our lives, namely powerful, weak power, electromagnetic and gravity.

The force that combines Quark is strong. The three quakes that make up the proton are independent of each other, but in fact there are a lot of glue in the middle of them. The role of these glue is responsible for strong transmission. Can you separate these quarks that are bonded together? Unfortunately, human beings have not done so far. The structure of the human research material is mainly to use a collision to bump micro -material, and even if it accelerates to 99%of the speed of light, we still have no way to open the quark. Why is this? In essence, to separate a substance, we must enter the energy to fight against the combination of combination, and this kind of thing is "strong in encounter".

Two adsorbed magnets rely on the combination of electromagnetic force. When we enter the energy to open the two magnets, the electromagnetic force between them shows a weakened trend, because the electromagnetic force and the square are inversely proportional to the square. The farther the distance, the weaker power.

However, this is not the case. The strength is proportional to the distance, that is, the farther the distance, the stronger the strength. When we try to enter the energy to open the two Quickla, the strength between them will be enhanced, so we need to enter more energy, and then the strength will be further enhanced, so we cannot pull it away. In fact, not only can we unable to pull it away, even strong neutron stars cannot destroy neutron substances formed by the combination of Quark. Perhaps in the universe, only the power of the black hole can be opened.
