As an almost graduated student of high energy physics (which includes subjects such as cosmology and string theory) I feel the urgent need to warn people about the utter nonsense that is displayed on this site. Not only are the concepts of four-dimensional space-time poorly explained, the rest of the presentation about the remaining six dimensions contains no truth value whatsoever.
It is very hard to falsify somthing that consists almost exclusively of pure nonsense (one would not know where to start) but I have the feeling that I should add some argument to my statement.
String theory is still a higly theoretical theory. It is not known if or how the extra dimensions are folded. It is not even known if string theory is a feasible theory for that matter, since up till now no contact has been made with experiment.
Furthermore the author of this site seems to think that we can attribute certain concepts to a single dimension and thereby forget the basics such as gauge invarance which is presupposed by the relativity of these postulated dimensions.
I could go on like this but I don't want to.
Now that my anger about this foolishness has subsided i am left with a profound sympathy for all those deluded souls that believe in this abhorring pseudoscience.
Sorry, I feel a bit like a prick to express my opinion so strongly but I feel that it should be said without mercy and without relent because as physicists we must endeavour to reveal the truth about the universe without holding back.
