At present, a higher scientific theory and technology of human beings has been constantly developing and perfecting, which is mainly due to a series of efforts made by human beings themselves for the development of our human society. Because of this, the initiation of our human talents belongs to our own influence. So the proposal of perpetual motion machine in the past was rejected by our human scientists, so why can molecules keep doing random motion? There are probably the following reasons.

First, there is something wrong with this kind of thing itself. First of all, the point of 1 is about the perpetual motion machine itself, because in our real life, nothing can exercise all the time, because in the world of material energy, all energy will be continuously lost, including our human body itself and sports materials. So it is precisely because of this that there is no such thing as perpetual motion machine itself. When it was first put forward, it was just an illusion that some people existed. Because material sports will constantly lose all kinds of energy, which is fascinating in our nature, that is, material energy will be lost.

Second, about the law of molecular motion. One more thing, as far as the law of molecular motion is concerned, it is an established fact that the molecule itself is doing irregular motion similar to that around it. Because molecules are too small to be seen by naked eyes, in nature, any substance can keep molecules moving, such as wind or other things in nature can make molecules move. For example, perfume is sprayed in the air, and the reason why our human noses can smell it is precisely this random movement.

Third, the world is always full of all kinds of magic. Finally, in such a micro-world, there are always various magical phenomena, and these magical phenomena are also attributed to an answer from the scientific community.
