What is "Time"?
If you have thought about "Time", you can't know what it is. "Time" is simple, but complex. Let's see simple sides of "Time".

"Time" is scalar quantitiy, like mass, length, electronics charge, is usually fundamental quantity. Time is combined with other physical quantities to derive other concept such as motion, kinetick energy, and field. Time is used in many many ways. There are no one knows what is "Time", in literary. It is simple side of "Time", you can understand.

You know, "absolute time" does not exist."Relative time only exist. But we use time like if "Absolute time"  only exist. Why it could be? It is not difficult. It is because we are too big! We are living macroscopic world that "Relative time" can't be seen.

Today we want to know more about "Time". It is "what is time Einstein think".

Einstein think there are no time as quantity that is independent from space. In this context, space has height, width and depth. Einstein said there are only space-time, this is not constructed by time AND space. IT IS IT.
Next, I want to show what is this. It is your world. You have own space-time(more exactly, particles consists you have own space-times)So your time and my time is not same. You may think cheat me, but please think again. Why do we have to think we are share THE time? Are there rational reason? I think there are no problem if we don't share same time, don't you? Existence of relative time is proved, so if you want to say "THAT IS LIE!!!" you have to think and make theory is more than rational and fit for real.
