Talk:String theory

The article says that in string theory, spacetime has either 10, 11 or 26 dimensions. But http://superstringtheory.com/basics/basic5a says:

That sounds crazy -- because bosonic strings live in 26 dimensions but supersymmetric string theories live in 10 dimensions. But the extra 16 dimensions of the bosonic side of the theory aren't really spacetime dimensions. Heterotic string theories are supersymmetric string theories living in ten spacetime dimensions.
