Pretty much an open end question...
What is time and what its purpose? From what Edward Casey said... it's an illusion but one with a purpose...

Time is, in my opinion, nothing more than the passing from one moment to another. One moment being the smallest unit of time possible (infintely small, perhaps?).
Maybe Pratchett even had a point in his "crazy" theory that the universe is destroyed and reshaped every moment to form the passing from one state to another.
Basically, our concept of time is our concept of change. We measure time by change, and every change perceived by us takes time. Likewise, something that does not change perceptibly is apparently devoid of time (such as a picture - while the paper it's printed on ages, the picture itself does not represent any unit of time, for it does not change).
Maybe time is just a concept we made up in order to be able to accept and understand that everything around us changes...

If it looks good, you'll see it.
If it sounds good, you'll hear it.
If it's marketed right, you'll buy it.
But if it's real... You'll feel it.

Nope, nah uh, not even gonna, never, No, I refuse. Lets just stick with, "Its a coordinate for a location." If you want to meet your friend, you not only have to tell them where, you also have to tell them what point in time to meet. So you tell em x,y,z,time. That's all I'm going into. 4th dimension. Oh, and you cant have space without time, and you can't have time without space. Fundamentally linked.

Ignore everything else for a second. Imagine you're shooting from the foul line (basketball). Now imagine what that looks like from the side. Can you see the ball travel from the person's hand and to the hoop? Each moment you perceive is a part of that object in time. The 4D combination of all the states it passed through in time is the 4D object of it (You cannot perceive this normally.). Freeze the action at a certain point and you can imagine all the 3D particulars of the object, but the 4D can only be observed by us as the "frames" they leave behind in the 3rd dimension.
That is what time is. A movie is 2D frames after 2d frames to make a continuous flow, similar to time. What you see is a 3D "frame" of a "object" (Or "fate", really/sort of) in 4D. Time itself, however, is everything, everywhere, at once. All the time.
This is grossly oversimplified, of course. The 4D isn't really 4D etc.

Best vid I've seen explaining all (every one you can possibly have) the dimensions. http://www.youtube.com/watch?v=uY_ZgAvXsuwProtip: Don't jump from a 7th dimension to an 8th or a 9th, you will die! |

I never liked how he went back to "a line" for the 4D. Doesn't really fit and seemed overly simplified. Likewise, the 2d could be better. It's a great explanation, though. Saw this a couple of moths back.. EDIT: Watching it again the recursive of "line" then "split" is driving me crazy.. They more stack on top of each other in complexity and showing it as just a line and split seems stifling :/ EDIT 2: Protip, there is a way to draw a line from a 10D "point" to make 11D  |

I thought it doesn't go to 11 (lol spinal tap) because people can't comprehend what another point would be.

Theoretically it does from the POV of string theory. They basically stuck an 11th one so the math would wrap up nicely. It's an anchoring of the 10 dimensions, so to speak. |
