The question of string theory's position on dark energy is an interesting one.

A few days ago, I read in Smolin's book that string theory had a problem with dark energy. A few minutes ago, I read in Polchinski's article that this wasn't so, and that, in fact, string theory predicted (Weinberg) dark energy before it was found!
