Abstract:

Abundance of lithium observed in the atmospheres of old stars, if interpreted as primordial, is in strong disagreement with the predictions of standard cosmology. This is a very complex problem, and at this stage it is not clear what is responsible for this discrepancy: conventional physics or elusive new physics that might have modified the standard cosmology. I will review a suit of Li-related questions focusing on recent developments.
