I'm not sure how to describe time.
My perception of time is like this: When I am thinking or imagining or if I am looking at a motionless object I often don't perceive time at all, in fact it would feel as though time has stopped or slowed down.
The same effect would happen when I am observing a distant scenic view.
Sometimes when I am observing something interesting I would ignore what is going on around me and concentrate on that object.
Now, here is the more important facts to remember about 'time'.
1) Time should 'not' be associated with the movement of the hands on your clock, after all what is the clock measuring?
2) In support of number 1, time is relative to the observor it is a consequence of Einsteins Special Theory of Relativity. To put it bluntly, the perception of time or the movement of the clock slows down when the observor in the ship travels closer to the speed of light (time dilation) Time is like matter, matter has a speed limit this being (the speed of light) and like matter light also has a speed limit (light constancy)
When matter closely matches the speed of light then matter would appear to slow down because it has effectively reached its speed limit of light speed. because light is constant and cannot gain extra velocity then matter like light also cannot exceed the speed of light. For instance, if Iwas traveling at the speed of light and I try to move my arm forwards in the direction of travel then that would mean that my arm is exceeding the speed of light, theoreticaly I would appear to look stationary due to the affect of maximum TimE Dilation, physically it would also be impsossible due to e= mc2.
Time dilalation in affect can almost preserve the rate of entropy or age on a person (twin paradox) were one twin on a spaceship would appear younger than his twin on earth.
The affet of time dilation can aso be seen on objects near a gravitational source (GPS reveivers have to account for timedilation all the time on onboard vibrating ceisium atomic clcoks).
Time dilation is also a consequence of length contraction (lorenzt lenth contraction).
I'm in a rush to wrtie this stuff ' 10 minutes on library auto logg off) sorry for the spelling mistakes.
Time can also be described as entropy or the increase in the disorder of matter, ie glass breaking, rusting of iron etc.
I've got to go I've got 1 inute to post this stuff!! ! AHHHHHHHHHHH
