What is the definition of time?

Answer 1

Something that never stops.

Answer 2

The "present" is the illusion we sustain in order to stay sane.
The actual present "moment" is so miniscule, that it is the equivilent in proportion to a quark within an atom... theoretical only.
The "past" and "future" do not exsist at all by absolute definition.
So we are left with "time", as a ghost-like dimension to which we are only partially able to sense, and to which we adhere to only indirectly. In a way-- time does not exsist as anything that can be defined by conventional concepts.
All we really know for sure, is that there is a lot more to it than we are capable of grasping!
Sure, you can get an answer that appears to be based on actual scientific formulas and understanding...however, even Stephen Hawking will be the FIRST to admit that the human species is, and always has been somewhat conceited and confident in its conclusions to what it knows very little of.

Answer 3

Heh, do you want the long or short answer? Too bad; you're getting the short one, because the long one involves way too much math.

Basically, it depends on what theory of physics you subscribe to:

1) Time is a dimension of a larger construct known as space-time, as first described by Einstein and subsequently modified and refined by several generations of physicists. Basically, it is tied in with the fabric of reality in the same way that spatial dimensions are; at least one dimension of time is required for you to exist, and you can think of yourself as riding, one second at a time, along this single line of time (it doesn't QUITE work like that, but it serves as a good visual aid)

2) A more classical view (Liebnitz et al) is that time is purely separate from space and matter, an invention of humans to quantify duration or order of occurrence -- that is, time is not something to be measured, but rather a tool used to measure other things.

Answer 4

Time is currently one of the few fundamental quantities. These are quantities which cannot be defined via other quantities because there is nothing more fundamental than what is presently known. Thus, similar to definition of other fundamental quantities (like space and mass), time is defined via measurement.

Answer 5

Time is what you measure with a clock. A clock measures change between two events. So really time seems to be the amount of change between two events. If you think about it, if nothing ever changed could you say that time passed?

Answer 6

Look for "A Short History of Time" by Stephen Hawkin

Answer 7

Wow, deep question. You must be very smart. Hope you won't think my answer is too dumb but I think time is one of two things. Scientificaly, it is the artificial system we create to orient ourselves in space. Spiritually, it is the one unique thing that sets us apart from other animals: the ability to perceive the future.

Answer 8

Time is the unit to measure the movement.

Answer 9

Time is the intangible, relativistic dimension that we all progress through.

Answer 10

WE ALL GET A FIX TIME FROM GOD
AND SEARCH IDEA TO PASS THIS TIME IN MANY WAYS LIKE EARNING,THINKING,

Answer 11

Time is relative
