A general Friedmann big-bang cosmology can be specified by fixing a half-dozen cosmological parameters such as the photon-to-baryon ratio ${\ensuremath{\eta}}_{\ensuremath{\gamma}},$ the cosmological constant $\ensuremath{\Lambda},$ the curvature scale R, and the amplitude Q of (assumed scale-invariant) primordial density fluctuations. There is currently no established theory as to why these parameters take the particular values we deduce from observations. This has led to proposed ``anthropic… Expand
