How Black Holes May Get String Theory Out of a Bind

摘要

Beautiful as it is, string theory has come to seem aloof from reality. The problem: It predicts too many universes. Many theoretical physicists have touted this elegant mathematical construct as the best candidate for a "theory of everything" that could embrace all the forces of nature, from those that work on the scale of atoms to the force of gravity. The theory describes all elementary particles as vibrational modes of infinitesimal strings. But there's a catch: Those strings naturally exist in 10dimensions.
