Need some help here from some fellow facepunch genius, so SPACE is the third dimension and time is considered to be the fourth dimension. But time only goes in one direction so doesn't that mean that it follows the principles of the first dimension, so why do we call it the fourth dimension? fixd
Yes.
"we live in the third dimension" What the fuck?
[QUOTE=Zanpa;40704784]"we live in the third dimension" What the fuck?[/QUOTE] Hey, I never said I understood any of this....
The second dimension goes in two directions (X and Y), Then comes the third dimension with X, Y, Z. Then the fourth dimension with X, Y, Z and time.

Ok so my problem was that I am separating the two when they are actually together? Thus Space+Time right? Thanks Higurashi. you genius

The first dimension can also go in two directions. I suppose time is the "fourth dimension" because it is the least intuitive. Note, however, that this is an arbitrary convention and there is nothing special about any dimension that makes it the first, second, third, or fourth.
