Ok anyone want to help me out. I have to think of a single, short definition for time and and one for space. Can be no longer than a paragraph and has to be a coherent paragraph at that.

Any good ideas?

Thanks

No I will not do your homework for you.

Space is defined in three dimensions x,y,z. Or, if you want, in polar coordinates.

Time is defined as the "fourth" dimension, as all of the other dimensions are orthagonal to it, and travel along it.
 

Those are two words that I have difficulty with. Almost all books I've ever read having to do with the subject of space and time never define the two words. It almost seems that one is expected to see and know what it is intuitively. If anyone finds a real definition don't hesitate to share.

In mathematics though, it comes in the form of vector space.

time is the motion of objects. space is a non-physical, abstract, kind of mathematical type of representation. btw i'm talking out of my arse.

It's all a matter of perception. Time can be considered space and space can be considered time. It takes time to travel through space but only in our perception.

They are both linear, yet repeat themselves. Think about it. Time repeats; you can look back on it but it will move forward regardless. Space is linear. It's infinite. But there are many definitions of space. Space can be empty or it can be full. People usually refer to "a" space as being empty but they are trying to fill it. Space is a void.

I know what I'm trying to say but I don't think I can put it into words well :eek:

Is space infinite? As we are still finding things the further we look out I assume we have not seen the end of the universe, so do we really even know if it keeps going or not?

We'll listen to a guy that can't handle one math class.

Time isn't the fourth dimension. It is a separate dimension, but the real fourth spatial dimension is right here
