When Did the 'Dark Ages of the Universe' End? This Rare Molecule Holds the Answer.

Interesting report on Big Bang cosmology. We have dark energy, dark matter, and the dark age(s). Recently I found out that the parameter for *predicting* the abundance of the primordial H/He ratio - a cornerstone of the Big Bang model is a free parameter that can be adjusted to get results we need :) Last night I viewed 4 Vesta asteroid with my telescope (again). The sky charts showed its position in Cetus. I did not need to adjust a free parameter to observe the asteroid in the heliocentric solar system :)
