The value of . reionization. fraction derived from CMB polarization measurements has decreased steadily since WMAP2003 (WMAP2005, WMAP2007, WMAP2011, and Planck 2015).

Historical tidbits. 1776: Laplace suggests four mechanisms that could explain secular perturbations of Moon-Earth orbit. One the explanations was a non-instantaneous propagation of gravity, affecting the binary system (abandoned because its speed would be too large to be measurable to explain the effect). .
