Time &Space

When I came of age, as if I lived my entire life -from our birth to the coming of age was thus we feel it's very long. In comparison to the first twenty years of our life, the next twenty years from 20 to 40 seems like time is as arrow -time flies. You see the older we are, the shorter the time we feel. The concept of time is just relative, I mean there's no absolute time in our universe.

Likewise is there any fixed space? Space is also a relative concept. Because we have certain size, we feel just big and small from our measures. But there's no width and length in space originally as no length of time exists in space.

Because we exist, we have time and space. Those concepts exist just relatively. There's no absolute time and space in our universe.
