Description
Big Bang Nucleosynthesis, Cosmic Entropy, Gravity, and the Cosmological Lithium Problem
Big Bang Nucleosynthesis remains as a pillar of modern cosmology against which any modification of physics in the early universe must be constrained. This includes Einstein’s gravity and our understanding of the formation and evolution of stars in the early universe.. In this talk we will explore a concept rooted in AdS/CFT correspondence string theory and quantum entanglement, that gravity is an emergent phenomena and that entropy, not gravity, could be the underlying force driving the cosmic expansion as described in Kaniadakis cosmology. Existing BBN constraints will be reviewed and updated. At the same time, the cosmic lithium problem remains unsolved in spite of years of effort. We describe simple solutions to this based upon the detailed evolution of stars within the Spite plateau that has been used to quantify the primordial lithium abundance for decades.
