The Big Bang

The Big Bang theory is one of the most fundamental theory of nature. In particular Big Bang Nucleosynthesis (BBN) is a parameter free theory, that gave one of the first and strongest evidence for the Big Bang theory. Current observation of primordial elements (that were produced during BBN), that are measured in some cases with an accuracy nearing 1%, are predicted at the same level of accuracy, with excellent agreement with observation. But one nagging problem remains: the production of 7Li in BBN is approximately a factor 3 and close to 5 sigma smaller than the prediction of BBN. This problem has been known over the last forty years as the "Primordial 7Li Problem".

We will review the Big Bang theory and BBN and describe an attempt to solve the lithium problem in the Master work of Emily Kading at UConn. We conclude that currently, there is still no standard solution to the lithium problem.
