Wikipedia Overview
In astronomy, the lithium problem or lithium discrepancy refers to the discrepancy between the primordial abundance of lithium as inferred from observations of metal-poor halo stars in our galaxy and the amount that should theoretically exist due to Big Bang nucleosynthesis (BBN). The Big Bang nucleosynthesis and WMAP constitute cosmic baryon density predictions of the cosmic microwave background (CMB); namely, the most widely accepted models of the Big Bang suggest that three times as much primordial lithium, in particular lithium-7, should exist. This contrasts with the observed abundance of isotopes of hydrogen and helium that are consistent with predictions. The discrepancy is highlighted in a so-called "Schramm plot", named in honor of astrophysicist David Schramm, which depicts these primordial abundances as a function of cosmic baryon content from standard BBN predictions.
