    Description
    One study the effect of increasing self-gravity (i.e., of increasing the string coupling g) on the energy and size of very massive (fundamental) string states. It is found that the size of a typical self-gravitating string state of mass M shrinks when g increases, and becomes comparable to its Schwarzschild radius when g2 M ~ Mstring. Such a compact string state has (in order of magnitude) the correct number of states to match the Bekenstein- Hawking entropy of a black hole. (Ref.: T. Damour and G. Veneziano, hep-th/9907030).
