Is time relative? If a men is in an uninhabited island, and he doesn’t want to go out, will he need the concept of time?
I think the answer is yes. Suppose that he has a lot of apples. The apples are going bad. He knows that he should eat apple before bad. The “before” then is the concept of time. But please be careful, the “before” is also means this time is relative. For this man, there are two time points. One is the time that apples are not bad. The other is that apples are bad. There is time concept between apples and this man, because of two reasons: 1. there are relationships between this two objects; 2. one of them is changing, and this change affects the relationship. The man wants to eat apples, the apples are going bad (here let us ignore the time that this man can live). If the man doesn’t care about apples, then for him, there is no time concept between him and apple. If the apple will not change, which means that the apple is not going to bad in this case. Then time is not necessary between those two objects, the man and the apples.
Time is related to the restless. If connection is common between everything, and everything is restless, then time is exist between everything, and time is relative. If one thing is stationary, then time lose its meaning for it, which means it is forever.
Is there anything stationary? Yes, the God, and more interesting, the time.
