Detection of Hydrogen Hydrogen is prevalent in the universe. Life in the universe is ultimately based on hydrogen. The are about 1xx 10^(23) atars in the universe. Assume that they are like our sun (radius 700.000 km , density, 1.4 g//cm^(-3) 3//4 hydrogen and 1//4 helium by mass). Estimate the number of stellar protons in the universe to one significant figure. In the 1920s , Cecilia Payne discovered, by spectral analysis of starlight , that hydrogen is the most abundant element in most stars.
