The only constant in the world is change, and the only possible thing in the world is impossible. What does this sentence mean? Seek a detailed explanation

The first sentence "the only constant in the world is change" means that change is an irreversible dynamic and nothing can change it, so it is the only constant in the world. Just like water turns into ice when it is cooled, and ice turns back into water when it is heated, water only turns into ice when it is cold, and ice only turns into water when it is preheated, which is irreversible and unchangeable.

The second sentence is that the only possibility in the world is impossible, which means that there is a saying that "the impossible becomes possible", so it means that the impossible and the possible are interchangeable.

Extended data:

This sentence was said by the Greek philosopher Heraclitus. Heraclitus believes that everything is always changing, and this change is carried out according to certain scales and laws. The original words are "Everything exists and does not exist at the same time, because everything is flowing, constantly changing, constantly producing and disappearing."

Everything in the world refers to objective existence, not matter. "Everything in the world is changing" is a summary of the regularity of material movement, a kind of understanding and a kind of consciousness of human beings. This sentence itself is not material, so it is not within the scope of "everything" and can remain unchanged. The law should be the same.

The essence of this sentence is to tell people to look at things with changing eyes and guide people's words and deeds in new discoveries.
