String Theory & Imagining the Tenth Dimension

[jAZ]

I thought this was fantastic. I hadn't ever seen the idea of the 10-dimensional universe explained this way. The key detail that helped me understand it in my mind, is the 7th dimension.

Dimensions 1-3 are easy.
Dimenion 4 is "duration" (time)... easy too.
Dimension 5 & 6 are time travel (interesting that time is effectively 3 dimensional)
Dimension 7 addresses alternate "infinite" universes created by different initial conditions of the big bang. The other universes have different rules than ours (ie, gravity rules are different there, etc).
