This word has to do with time. More significantly it has to do with opposite meanings of happiness or sadness. In the same time it has to do with human thinking. Simply because fraction of thought with lead to significant human thoughts. As a result this endless thought does have multiple cases of meaningful explanation for the best to come.

A fraction also has to do with space. A fraction of a distance in space could be argued about in millions of years. In this fashion of thinking human being is able somehow to trace his origin. But human beings will not be able to measure this form of fraction.
