Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Elemental abundances throughout the universe are formed and distributed primarily through stellar nucleosynthesis processes, such as core-collapse supernovae, neutron-capture reactions, and stellar evolution.

The analysis

The claim is a well-established scientific fact in astrophysics. Multiple retrieved papers explicitly discuss how stellar processes, nucleosynthesis pathways, and supernovae determine chemical and isotopic abundances across the universe.
