k, i got another. we apparetnly live in a 3rd dimension. (some believe its a 4th dimension with time as the forth whatever) . 1st dim. is a line (length). 2nd is flat shapes (width x length). 3rd is shapes with depth (width x length x depth). then, if you believe, 4th Dimension is width x length x depth x time. (thats why im sure it could exist, because i think you would have to add time, not multiply. but saying it does...).

now all that should make sense so far. heres the twist. what if we had different combonations of mutlipliers. like width x length x time. this would still be a 3rd dimension... yet a completely different world. thats all i got really. i thought i had more, lol.
