Does string theory predict additional long range forces gravity EM?
One of the most touted features of String theory is that it correct predicts and even requires 2 infinite long range forces, gravity and E&M.
I've heard that string theory though also predicts additional non-observed long range forces which are not observed, and allowing gravity and E&M to exist in string theory while suppressing the non-observed long range forces requires a lot of fine-tuning. Another way to hide these long-range forces is to associate them with dark energy.
Is this correct? if gravity is a triumph of string theory then what about unseen forces that are equally an implication of string theory?
