Precision Cosmology from WMAP

The WMAP satellite has allowed the very precise determination of many cosmological parameters

parameter WMAP value what is it?
Omegatotal 1.02 +/- 0.02 total density
OmegaLambda 0.73 +/- 0.04 dark energy density
Omegamatter 0.27 +/- 0.04 matter density
Omegabaryon 0.044 +/- 0.004 baryon density
Ho 71 +/- 4 km/s/Mpc Hubble constant
to 13.7 +/- 0.2 Gyr (billion years) age of the universe
