Just watched a show on the Nat. Geo. channel about Stephen Hawking and his quest for a theory of everything, and it led to a discussion about string theory. Try as I might, I am simply unable to mentally visualize and thus fully comprehend the concept of nine dimensions. I understand what they are saying (sort of), but I simply can not visualize it. They even had little graphics to demonstrate the extra dimensions, yet that still looked two and three dimensional (for obvious reasons) and didn’t help me conceptualize nine dimensions at all.
I’m assuming my brain is just wired differently from those who grasp this.
