The fourth dimension is really awesome. I'm not just talking about math things for computer games, in fact I doubt many game programmers could even draw a geometric representation of the w coordinate of a four dimensional vector. But seriously, pretend you are shot and you go to a four dimensional surgeon. That surgeon could reach out and grab the bullet from inside you without ever touching you. How is this possible? Easy! It's possble in the same way it is possible for three dimensional beings to pick up and move objects on a plane without ever having to touch any boundries on that plane (because us nifty three dimensional folk can travel through the z coordinate while planar entities cannot, they suck).
and the fourth dimension isn't time because none of the (infinitely small) three dimensional slices that make up four dimensonal hyperspace are related in anyway, similarly the infinite number of planes that make up space aren't related. If you believe the fourth dimension is time you are wrong and should be slapped...seriously.
Sometimes I look at otherwise ordinary objects, and I try to imagine them as both infinitely thin but also tangible and real at the same time, and it makes me feel funny and sometimes I throw up.
Have you had a four dimensional experience lately? I bet god is just a four dimensonal being playing tricks on us.
EDIT: and if you disagree with me on any aspect you are wrong because I am a teenager and I know everything and my mom can beat you up, and I'm just pretending to be a poser.
