comment Why are extra dimensions necessary?
Mark, I got that example by misreading en.wikipedia.org/wiki/N-body_problem. It's not really wrong (e.g. it could describe a moving, spinning sphere at a certain temperature). I deleted my previous comment and I have decided to leave my answer as-is.

I think those who have been interpreting this strictly as a string theory question are reading a little too much into it. It's not clear whether "BS" stands for bosonic strings or something else.
