The recent announcement from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite experiment combined with other recent advances in observational cosmology verifies key components of the standard cosmological model. However, [ Bridle et al .][1] argue in their Perspective that there remain some significant open issues regarding the basic history and composition of the Universe and uncertainties in some of the most important parameters.

Cosmography: Cosmology without the Einstein equations (2004, background): “Despite the fact that some parameters in cosmology are now known to high accuracy, other parameters can still only be crudely bounded [ 6 ].”
Jerk, snap, and the cosmological equation of state (2003, background): “Despite the fact that some parameters in cosmology are now known to high accuracy, other parameters can still only be crudely bounded [ 21 ].”
The Three-Dimensional Power Spectrum of Galaxies from the Sloan Digital Sky Survey (2003, background): “As emphasized by Eisenstein et al. (1999) and Bridle et al. (2003), WMAP alone cannot determine Ωm to better than a factor of two or so because of a strong degeneracy with other parameters.”
Deuterium abundance in the most metal-poor damped Lyman alpha system: converging on Ωb,0h2 (2008, methodology): “It is still important, however, to measure these parameters with alternative methods, partly as a consistency check on the standard cosmological model, but also because the CMB fluctuations generally constrain combinations of more than one parameter (e.g. Bridle et al. 2003).”
Reconstruction of the early Universe as a convex optimization problem (2003, unknown): “17 Data of the first year Wilkinson Microwave Anisotropy Probe (Spergel et al. 2003; see also Bridle et al. 2003) suggest a value σ8 = 0.84±0.04, marginally smaller than the one used here.”
Cosmological parameters from cosmic microwave background measurements and the final 2dF Galaxy Redshift Survey power spectrum (2006, background): “One interpretation of this apparent discrepancy is that new physics may be needed (e.g. Bridle et al. 2003a; Efstathiou 2003).”
Cosmological parameter constraints from SDSS luminous red galaxies: a new treatment of large-scale clustering (2009, background): “However, degeneracies exist between some parameters which cannot be broken by CMB data alone (e.g. Bond, Efstathiou & Tegmark 1997; Efstathiou & Bond 1999; Bridle et al. 2003).”
