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 |
