The meaning of time

 Well, what conclusions or ideas of this work?Einstein put the time «elastic» in his theory. Time, outside of our world, in intergalatic travel, could change more or less. Is like a fourth dimension, as space.In our real world, time put us running, geting old, be late, absent or even waiting. Good and bad things, dates that we never forget. But in fact we don't see the time and to feel it, we must think on it. My opinion goes in the sad sense, this is, when we are sad. The objective is to understand if the «time» block us the hapiness. Or not?Good luck, my friends!
