| Mar 29, 2021 at 23:54 | comment | added | ProfRob | @GluonSouo By looking at the He abundance in the most metal-poor galaxies and comparing it with the He abundance of gas in our galaxy. The difference is a few percent. | |

Putting aside the production of Deuterium and lithium, are there any studies on how much Helium has been produced by stars in 13 billion years?That is, I'd like to know, of the 24% of helium observed, what fraction of that was produced in stars? | |
