Main Question or Discussion Point
I've been reading into String Theory and M Theory lately and I think I have a general picture of what it's about, with the infinite parallel universes and whatnot. But this theory is built on the idea of 11 dimensions. I don't understand this.. how is it possible to imagine the 5th+ dimension? The difference, or leap, from the 2nd dimension to the 3rd is astronomical, as is the leap from the 3rd to the 4th. I find myself barely able to comprehend the basic idea of the 4th dimension in relation to our place in the multiverse, but it's completely beyond me and anyone else (I would assume) to grasp the concepts of a 5th or 11th dimension. The fundamentals seem light years beyond our imagination. How is it that scientists can talk of an 11th dimension, then?
