We have heard this many times, people always say, you should not waste your time, time is money but have you ever thought that what is time, what is the fundamental nature of time?
Many people have tried to solve the mystery of time but as time passes things get fuzzy and time seems to hide its identity from us.
The problem with time is that you think about it and it passes away without giving you a clue about it and you know that it has passed away but you don't know what it is.
Time is an integral part of the Universe. It is something which prevents everything from happening at once.
Some scientific theories state that time is unidirectional while some of them destroy the very notion of the past, present and the future.
The human mind percieves time in a very systematic way, we percieve events frame by frame so we can say that time is deeply associated with our memory. You don't feel time but your accumulated memory tells you clearly about its existence.
Time can be defined as linear progression in occurence of continuous events happening in the existence. Do you really understand anything from this definition? We can define it but we don't really understand it entirely.
Time still remains a mystery , an unsolved problem. Probably the answer to this question is just around us but we have not realized it yet perhaps in this modern materialistic world we don't have enough time to think about this question and to question our own existence.
