DESCRIPTION:Although at first sight it may seem an odd idea\, I will argue
  that it is actually quite natural to investigate the properties of Genera
 l Relativity and its black holes in the limit in which the number of space
 time\ndimensions grows to infinity. The theory simplifies dramatically: it
  reduces to a theory of non-interacting particles\, of finite radius but v
 anishingly\nsmall cross sections\, which do not emit nor absorb radiation 
 of any finite frequency. This leads to efficient calculational approaches 
 in an expansion\naround this limit\, as well as to intriguing connections 
 to low-dimensional string-theory black holes.
