What is the time?

Question

I mean the nature of time, not hour.

Answer 1

time can only be measured by an observer who has the ability to both recognise and form some mechanical device to divide said time into usable chunks.
Humans like plants and animals have a biological clock - a series of biochemical mechanisms that register daylight and in that sense our brains recognise time. When we are busy, time seems to pass very quickly as our brain is occupied on something and doesnt pay attention to the signals given off by the clock unless we become tired, which is a different signalling system. Likewise, it will pay great attention to the passage of time when bored, but more likely as the mind unsuccessfully thinks of something better to do!

Answer 2

I think it would have been better to leave out "the and make your question "What is time"; you might, then, have had fewer stupid answers from equally stupid people who couldn't be bothered to read the whole question.

TIME is the means by which we measure our lives. I have been alive 65 years and five days and I guess you are about a third of that or less. It is far more difficult to measure time this way, e.g. one third of a life is much less for you than it is for me.

It is, therefore more practical to have a standard measure i.e. TIME.

My year, month, week, day,hour, minute, second are the same as yours so that if I tell you to boil an egg for five minutes it is something you can do easily but if I said boil an egg for one 6,834,240th of a life (approx 5 minutes when you consider my life) and you tried to do it using your life, you would end up with a seriously undercooked egg.

Mr. JJ has given a beautiful answer to this philosofic/scientific question. I am only supplimenting it. Time is essentially a sort of distance between two events. This requires an observer. To an observer the gap between two events can be said to be the time. The universe was created in a big bang event some 10 raised to power 14 years ago. Before that event there is no concept of time since there was no observation of any event by any observer. Thus this can be the longest unit of time. The shortest unit of time is called femto second which the scientists have observed/measured to be 10 raised to minus 15 seconds. This is the time taken by a photon in the photo synthesis reaction.

Answer 4

Time has long been a major subject of philosophy, art, poetry, and science. Though dictionaries present some (varied) definitions of time (some of which are presented below), it is difficult to provide an uncontroversial definition because there are widely divergent views about its meaning, and concerns about whether there are any simpler terms with which to define it. Scholars also disagree on whether time itself can be measured or is itself part of the measuring system. To avoid these definitional problems, many fields use an operational definition in which only the units of measurement are defined.

The measurement of time has also occupied scientists and technologists, and was a prime motivation in astronomy. Time is also a matter of significant social importance, having economic value ("time is money") as well as personal value, due to an awareness of the limited time in each day and in our lives. Units of time have been agreed upon to quantify the duration of events and the intervals between them. Regularly recurring events and objects with apparent periodic motion have long served as standards for units of time. Examples are the apparent motion of the sun across the sky, the phases of the moon, and the swing of a pendulum.

Time has historically been closely related with space, most obviously with spacetime in Einstein's General Relativity.

Answer 7

Possibily an illusion based on your perception of reality strengthened by your beliefs.

Try staring at a clock on the wall, the one with hands and belief that you can stop time.

Your've already had this experience before, remember time stands still, or time flys.......yeah sometimes it does.

Anyway stare at the hand and mentally try to stop it or pull it backward. You may be impressed to see what happens. Opps almost forgot, make sure you look at it out of your periphial vision. This allows your mind to be concentrating on something else and thus you can interupt the idea of time progressing for about a second or so.

If your really interested considering Einsteins theory of relativity, and perhaps some quantum physics.

Enjoy life

Answer 8

Time is a dimension, like the three dimensions of space. God is not bound by time. Everything is written in the book of life, everything is drawn in the painting of life, in the four dimensions. For us to perceive it, we need to live it through these four dimensions. Every effect has a cause. The wisdom of the divine is infinite.

Answer 9

linear time is a river carrying you into the future. We have no control over the speed or direction of the current at present, you can only paddle to different places between the river banks, never go back, nor paddle faster.
