I'm glad that was helpful. I'm in a similar boat of just being interested in this for fun. I have a little more of the math and physics background for it, but it's pretty rusty and I don't need it to understand even most of the interesting papers. You probably want to understand three areas in more detail than you'll get from the wikipedia links I sent: 1) cosmology (people gave several good recommendations already) 2) wrap your head around the weirdness of quantum physics. I really enjoyed Six Impossible Things by John Gribbin as a good intro to different equivalent ways of conceptualizing…

This paper [0] from a couple of days ago (24 Feb 2020) found that Betelgeuse's recent dimming was not caused by a drop in the star's surface temperature. "We present optical spectrophotometry of the red supergiant Betelgeuse from 2020 February 15, during its recent unprecedented dimming episode. By comparing this spectrum to stellar atmosphere models for cool supergiants, as well as spectrophotometry of other Milky Way red supergiants, we conclude that Betelgeuse has a current effective temperature of 3600 +/- 25 K. While this is slightly cooler than previous measurements taken prior to…
