Age of the Universe
* History: The first estimates were based on the Sun's lifetime, but the oldest globular clusters are 13.5 2 Gyr old.
* Methods: Cosmochronology of long-lived radioactive nuclei; Stellar modelling and population synthesis of the oldest stellar populations; Precision cosmology with mapping of the acoustic peaks in the cmb.
* 2000: t0 13 Gyr.
* 2003: t0 = 13.2 (+3.6–2.0) Gyr (1-), or 14.0 0.5 Gyr [cmb].
* 2003: 11.2 < t0< 20 Gyr, t0 = 14.1+1.0–0.9 Gyr from WMAP+SDSS+SNIa.
* 2006: Accepted value 13.7 Gyr; Results based on measurement of Triangulum galaxy distance indicate a value 15% higher.

Cosmological Parameters > s.a. cmb; cosmology [theory]; relativistic cosmology [averaging]; matter content [including distribution].
* Idea: The main tools to obtain estimates are measurements of the microwave background, supernovae, and galaxy clusters (distribution, lensing, X-rays, Sunyaev-Zel'dovich effect).
