Spacetime has a positive cosmological constant, so it's closer to de-Sitter than Anti de-Sitter. It doesn't really have to do with curvature exactly, which is given by the Riemann tensor (so it doesn't make sense to say it's positive/negative).
- codethief 10y agoBut you certainly can talk about curvature scalars being positive/negative which are derived from the Riemann tensor.
