Thank you for your answer. I accept it as correct.  I read an article about how the Higgs Boson could be the inflaton.  I hope the process of energy acquiring mass and its possible relationship to expansion is something physicist continue to research.  I don't think I will ever be able to acquire the knowledge to express my ideas and questions into math, so thank you for the feedback.

I've never seen any suggestion that the later/present "expansion" phase has anything to do with supernovae, etc. So I don't think there's any link at all (coincidence or otherwise) between the first two points mentioned.

Is nucleosynthesis responsible for the expansion of the universe?

1. Big Bang nucleosynthesis occurred very close to the inflationary period.
2. Supernova and stellar nucleosynthesis created heavier elements as the stars died, and the universe underwent increased acceleration.

Big bang nucleosynthesis did not happen "close to the inflationary period".
inflation happened at about $10^{-36}$s. Nucleosynthisis happened from about 10seconds.

In relative terms, the ratio of the age of the universe now, to 10 seconds is much much smaller than the ratio of 10 seconds to $10^{-36}$s. And, significantly, nucleosynthesis occurred after inflation, so can't be the cause of inflation.

As for dark energy, nobody has any real model for it. The test for any theory is how well it does empirically. As it stands you have advanced a pet theory, without any mathematical model or analysis.
