I want to know the definition of "Time"?

Question

please only answer if you know

Answer 1

Time is the number of occurence of one event relative to another event such as the number of earth revolutions around the sun relative to the number of revolutions of another planet, say Pluto, around the sun.

Answer 2

Time is one of the few fundamental quantities.
These are quantities which can not be defined via other quantities
Thus, similar to definition of other fundamental quantities (like space and mass), the unit of time alone is defined.

One can understand time only by intution

The defintion that time is the interval or period between two events is not a defintion because we dont know what is period or interval with out the definition of time.

Answer 3

Einstein did a lot of research on time and he also believed in a supreme creature's existance(God).So according to him or his followers,time is gods way of keeping all things from happening at once.Time also has a direction.Time has a direction towards more entropy.Entropy is the amount of diorder.You might ever wonder this question-In free space ,u shoot a bullet thru an egg,the egg shatters causing change in entropy in the system(obviously increasing bcoz entropy never decreases).But consider the reverse.U shoot a bullet in reverse direction from in between the shattered pieces of the egg.the egg dosent reform.WHY? arnt the conditions reversed ? This question(not exactly,but questions like these..u understand dont u?) gave rise to the concept about the direction of time.this is only one definition of time.U can get more complex definitions.Just type "time" in google search and explore any topic that refers to Albert Einstein

Answer 4

Time for a given system or frame of reference is defined as "flowing" or going in to the "future" where entropy for said system increases--or goes from more ordered to a more disordered state.
Time is not a constant, so the passage of time is not a constant rate. It is all relative to the observer. Yes, oscillations of certain atoms (such as cesium see http://tycho.usno.navy.mil) are used to measure time's passing, but that is for the frame of reference which the clock doing the measuring is part of. Two different observers or clocks can have two different descriptions of time, when, now, then, etc based on their state of motion and location relative to a gravity well. Space is also not a constant. The only absolute frame of reference is spacetime.

Answer 5

That is waaaay to complicated to answer here. Heck, people still don't completely agree on a single definition of time. Check the Wiki:

Answer 6

It is a human perception.

It can be eliminated from all equations in physics by replacing it with coordinate differences. It is not neccessary. It does not exist.

All things happened at once....just are. We just happen to be experiencing different"nows" from different coordinates that seem unique and flowing. Seems like I've been at this now before. I guess I've always been here.....and everywhen else too. I don't seem to get around much...but I feel spread thin.

Answer 7

# an instance or single occasion for some event; "this time he succeeded"; "he called four times"; "he could do ten at a clip"
# an indefinite period (usually marked by specific attributes or activities); "he waited a long time"; "the time of year for planting"; "he was a great actor is his time"
# a period of time considered as a resource under your control and sufficient to accomplish something; "take time to smell the roses"; "I didn't have time to finish"; "it took more than half my time"
# a suitable moment; "it is time to go"
# the continuum of experience in which events pass from the future through the present to the past
# clock time: the time as given by a clock; "do you know what time it is?"; "the time is 10 o'clock"
# clock: measure the time or duration of an event or action or the person who performs an action in a certain period of time; "he clocked the runners"
# fourth dimension: the fourth coordinate that is required (along with three spatial dimensions) to specify a physical event
# assign a time for an activity or event; "The candidate carefully timed his appearance at the disaster scene"
# a person's experience on a particular occasion; "he had a time holding back the tears"; "they had a good time together"
# set the speed, duration, or execution of; "we time the process to manufacture our cars very precisely"
# meter: rhythm as given by division into parts of equal duration
# regulate or set the time of; "time the clock"
# prison term: the period of time a prisoner is imprisoned; "he served a prison term of 15 months"; "his sentence was 5 to 10 years"; "he is doing time in the county jail"
# adjust so that a force is applied and an action occurs at the desired time; "The good player times his swing so as to hit the ball squarely"

Answer 8

i do not know your standard of education but i shall make you understand. actually there are 4 dimensions in the universe as far as relativity is concerned.the three dimensions are space coordinates like length, breadth, and height. there is also another dimension called time you must visualize that as a point in space has three coordinates in space in our 3_d view . similar to this every point in space is defined by another coordinate called the time coordinate every point in space corresponds to a point of time .if a point in space time corresponds to 3.85th of a second the next adjacent point belongs to 3.95 neglecting the presence of infinite number of points in between any two points.as such there an infinite * infinite matrix in which each element corresponds to an unique cooridnate in space so time is the third dimension in the space. but take care that the space and time are mingled together to form a space-time coordinate

Answer 9

The unit by which the presence or length of all events in the physical world are measured.

Answer 10

One could say that - Universe itself does not have any concept of Time.

Time is a man-made concept, unlike space. It allows us to measure many things.

Time is a measure of 'ticks' between any two events.

You could draw parallels to it in terms of Kilometer/Mile. These measure distance between two points, Time measures distance(in 'ticks') between two events.
