How is the 'Time' defined? aka What is 'Time'??

Question

Where on the internet we can find definitions?

Answer 1

There are two ideas of what "time" is:

Newton would say time is the dimension within which the universe exists in a sequenced order and it can be measured in logical units.

Leibniz would say it is a mental method of positioning ourselves in relationship to the duration of events, the order in which they occured and the intervals between them.

So does time exist as something real, all around us? Or is it just the way we measure events?

Answer 2

Time, conscious experience of duration, the period during which an action or event occurs. Time is also a dimension representing a succession of such actions or events. Time is one of the fundamental quantities of the physical world, similar to length and mass in this respect. The concept that time is a fourth dimension—on a par with the three dimensions of space: length, width, and depth—is one of the foundations of modern physics. Time measurement involves the establishment of a time scale in order to refer to the occurrence of events. The precise determination of time rests on astronomical and atomic definitions that scientists have established with the utmost mathematical exactness.

Answer 3

The second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.

The second is the SI base unit of time measurement.

However, time is variable and is dependent upon your frame of reference, especially concerning velocity. [As per the space-time continum].

Answer 4

Time is actually a creation of physics...it is what's considered the fourth dimension (the other three being length, width, and height)

Answer 5

Time is a nonexistent measurement of life.
