Black hole

  1. Jun 16, 2008 #1
    Why the physicists studying a "AdS black hole"?

    what is the meaning of AdS (Anti de Sitter) for black hole? and why not we study de Sitter black hole?

    AdS space is important for the conjectured duality between superstrings in AdS space and a certain quantum field theory on the boundary of AdS space. At finite temperature, there is a black hole in AdS space (in other words, it is only asymptotically AdS). The conjecture goes by the name of AdS/CFT or gauge/gravity or gauge/string duality.
