Quantum gravity in 2+1 dimensions with a positive cosmological constant canbe represented as an SL(2,C) Chern-Simons gauge theory. The symmetric vacuum ofthis theory is a degenerate configuration for which the gauge fields andspacetime metric vanish, while de Sitter space corresponds to a highly excitedthermal state. Carlip's approach to black hole entropy can be adapted in thiscontext to determine the statistical entropy of de Sitter space. We find thatit equals one-quarter the area of the de Sitter horizon, in agreement with thesemiclassical formula.Comment: 5 pages, harvmac. v2: reference adde
