Line 90:
Considering the possibility that BBN predictions are sound, the measured value of the primordial Lithium abundance should be in error and astrophysical solutions offer revision to it. For example, systematic errors, including ionization correction and inaccurate stellar temperatures determination could affect Li/H ratios in stars. Furthermore, more observations on Lithium depletion remain important since present Lithium level might not reflect the initial abundance in the star. In summary, accurate measurements of the primordial Lithium abundance is the current focus of progress, and it could be possible that the final answer does not lie in astrophysical solutions.<ref name="fields11" />

Now consider the possibility that the measured primordial Lithium abundance is correct and based on the [[Standard Model]] of particle physics and the standard cosmology, then the Lithium problem implies errors in the BBN light element predictions. Although standard BBN rests on well-determined physics, the weak and strong interactions are complicated for BBN and therefore might be the weak point in standard BBN calculation.<ref name="fields11" />

All these nuclear physics solutions are accessible in experimental validation, which make them highly possible resulted in a true answer.

Under the assumptions of all correct calculation, solutions beyond the existing Standard Model or standard cosmology might be needed.<ref name="fields11" />
