We measure a second as the time taken for some n number of cycles of the radiation that gets an atom of caesium 133 to vibrate between two energy states. Basically we have defined time, more precisely all of the fundamental quantities, on the basis of repetition of something. Some predefined standards have been set so as to stage the act of explaining the phenomena in nature.
Now just imagine that the scientists who say that the absolute thing is Time. All other quantities are dependent on time. Now, just think about the concept on which time is built on. A scheme of repetition comes into play. What we actually see is that all the quantities sustain each other. Now suppose you just now have taken birth in deep deep deep deep deep deep deep space where there is apparently nothing. There is nothing absolutely nothing all around. You constantly try to move forward or backward in any one particular direction. Will you be able to reach anywhere? Will the concept of time still hold. Or will we need something else to define it. So don’t you think so that time is also dependent on something else.
