What Is Time?
Everyone knows what time is. It is what we measure in minutes, hours, days, etc and we follow it with clocks and calendars. In simple words, it is a dimension along which events are ordered from the past through the present into the future, it is a dimension along which we measure the durations of events and the intervals between them. Don’t you think time is more than this statement? Ever you wonder, what is time? Is there something more about time? Is it just what clock and calendar measures or something more? What is time actually?
Time is a concept, it’s a self-evident concept. We all know about it, don’t we? But there is more than that, there is a lot more about time. There are many perceptions about time, there are many theories which explains what actually time is. Early in the back days, people used sun and stars instead of clocks. Humans always felt the need of the concept of time. This post is about the time but I don’t want to go much deeper into this topic as this topic is too broader to explain with lots of theories, philosophies, physics and then of course my own perceptions about time and I don’t want to make this post too complicated to understand.
Here’s a few words on this topic, a few words to explain what I think about time in very simple words:
Time is basically divided into past, present and future, so lets start with past. Anything which happened doesn’t matter whether it’s known to you or not, it is past. Present is infinitesimal and future doesn’t exist, it’s just based upon the events of past and present. Everything which is happening right now can contribute to the future of anyone. The things someone did in the past, the things someone is doing in the present can play a part in shaping someone’s present in the future including his own present of the future. Future is a projection created by our imagination, knowledge, experiences or by the acts of anyone. When you draw something with a pen on a piece of paper, the things you have drawn is past and the thing you are drawing is present, it’s just all about the touch of the tip of pen to the paper and as soon as it touches the paper present becomes past and future becomes present, that’s how small is the present and all the things you are about to draw is a future. So past, present and future they all exist without the concept of time.
Lets try to go little deeper in this concept. Time is a concept to measure the motion of anything or the change in anything, considering the motion of all particles; the motion of atoms. It’s a concept to measure the motion or the change in the whole universe. How do we measure anything like if we have to measure weight? We just compare it with some kind of standard that we have defined. By comparing something with a particular standard we calculate or measure the unknown things, that’s how we do it. We have created standard to measure things and to measure motion or change we have created the concept of time, like miles per hour, 24 hours is equal to one complete rotation of the earth on its axis, then one revolution of the earth around the sun is equal to 365 days(one year), etc. It shows that when we are dealing with time we are actually dealing with some standard of motion. When there were not any clocks as we have now, people used to measure time with the help of position of the sun and stars. We always felt the need of such concept and it’s a part of our living. If we didn’t have clocks then we would be depending on some other things and we would make some other concept to measure the events, changes and motion. If somewhere in the universe there’s a life then it’s possible that they might have created some other concept as we have created the concept of time. Time is attached with the motion and forces. It depends upon the motion and the forces of atoms, it depends upon the motion and the forces of everything which exist in the whole universe as everything is made up of atoms.
From the above written post, we can conclude that time is just a standard to measure motion and change, a standard created on the base of motion and forces, and that’s why it changes at different points in the universe. Existence of anything doesn’t depend upon the time; past, present and future are not time dependent. Time is just a concept that we have defined. So I don’t believe in the possibility of time travel; to me the concept of time travel doesn’t make any sense, you can’t go back in the past, you can’t turn an omelet into an egg. However, nothing is sure as reality is too deep and there is no deep reality. Lastly one more thing, we can go to the future and we are going there right now as the present is infinitesimal!

“Time” has fascinated me for a while. Especially the differences between mechanical time and “natural” time. have a great day.
The symphony of science 🙂 That’s what I’ve tried to explain. Time is nothing, it’s just a standard to measure motion and change, a standard created on the base of motion and forces, that’s why it changes at different points in the universe. One can’t have the same standard of time at all the places in the universe. Past, present and future are not time dependent. Time is just a concept that we have defined!

Yes, contemplating time has always lead me very deep into my own self-exploration. One all-time (pardon the pun) favorite of mine:
“Time will always bring forth time and life will always serve life” (Albert Camus in The Myth of Sisyphus).
