Abstract Big bang nucleosynthesis (BBN) is the creation of the light nuclei, deuterium, 3 He , 4 He and 7Li during the first few minutes of the universe. Here we discuss recent measurements of the D to H abundance ratio, D/H, in our galaxy and towards quasars. We have achieved an order of magnitude improvement in the precision of the measurement of primordial D/H, using the HIRES spectrograph on the W. M. Keck telescope to measure D in gas with very nearly primordial abundances towards quasars… CONTINUE READING
