Well, last I counted, there were only 5 dimensions in the universe that we could comprehend in our own minds what the difference would be. I don’t know where these other people are getting 9. I think they’re just playing with you, man.
Tormod seems to know what he’s talking about. The others, I think, are just messing with you. You see, you have the 0-dimension being a single point, the 1-dimension being a strait line (Or length, the x variable), and the 2-dimension adds width to the mix (Y variable, the graphs we generally see in algebra class). The 3-dimension gives us height, the Z variable, which is the last dimension that we, as humans, can physically see. Shapes such as Cubes are 3D, where as squares are 2D.
The fourth Dimension, Time, is where it gets tricky. We can’t really represent it by a graph all that well, to we’ve resorted to looking at it like the 1-dimension. As a Time Line. I think they use greek letter Theta to represent the variable for time, but I’m not sure. Correct me if I’m wrong.
Now, looking at time as a 1-dimensional line, we can feasibly see what effect it would have if we were to add a dimension to that, the 5-dimension. Adding a second dimension adds the ability to branch off the time line and expand into, say, alternate universes and such, if you’re into Sci-fi novels and stuff like that.
The best I can explain this as is that if the 4-dimension were Fate, the 5-dimension would be chance, or the ability to go against fate. Sorry if this doesn’t help you any, but this is just what I came up with on my own. If there’s anyone who can correct me, I would love to hear it.
