11 Dimensions???

I don't get it ... i know time is the 4th dimension ... but, whats up with the other 7.

Ok, pretend that a third dimensional being crosses into a two dimensional space, and from the perspective of two dimensional beings (we'll call them flatfuckers) they only see the intersecting area in 2D since they can't perceive any further dimensions.  Now, based on that analogy, you can have a higher dimension crossing into the third and fourth dimension, and using another analogy, if each dimension is a point and you were to fold your paper to make dimensions intersect, that would be accessing an even higher dimension.  So yeah, it's all based on kindergarten logic and clever analogies.
