Mr. Mysteries' So-True Histories Episode 3 - Particles to Stars

Hello Eager Learners! I am Mr. Mysteries, formerly of the Learned League, and this is my KARENcast series on the history of our Reality, Reality 69.
  Our next ten episodes will cover the history of our Reality up to the point of splitting from the root, our Great Divergence. Having touched on the first second of reality, we will now do an equally deep dive into the first billion years, hope you have set aside some extra time for this one.
  Just kidding, the first billion years were actually fairly boring compared to everything else.
  <An indepth monologue follows describing the eradication of hadrons, leptons and anti-leptons, the beginnings of gravitational collapse and the formation of stars and quasars.>
