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 General Relativity a
nd its black holes in the limit in which the numbe
r of spacetime\ndimensions grows to infinity. The
theory simplifies dramatically: it reduces to a th
eory of non-interacting particles\, of finite radi
us but vanishingly\nsmall cross sections\, which d
o not emit nor absorb radiation of any finite freq
uency. This leads to efficient calculational appro
aches in an expansion\naround this limit\, as well
as to intriguing connections to low-dimensional s
tring-theory black holes.
