Scientific paper

Cosmological deuterium production is sensitive to variations from the homogeneity which is assumed in standard cosmological models. We demonstrate that a wide range of possible variations in primordial shearing velocity fields can produce deuterium with an abundance comparable to (or exceeding) the observed value even in closed models, without greatly altering the production of helium or appreciably distorting the isotropy of the microwave background radiation.
