Thanks again for your insights. I'll share this all with my son, he really appreciated your initial feedback and this is even better. I'd forgotten to mention the neutrino energy. I've talked to him about them in other context previously and this will help tie it all together.

Drakkith and Vanadium 50 thanks for your feedback. You've articulated a lot of the ideas that my instincts were pointing me to. Based on your posts, I think a good way for me explain it to him is that the bulk of the star has a very high energy density, largely described by the kinetic energy...

I was talking with my 14 year old son and he asked me a great question. He said he was thinking about the fact that it takes 100,000-1,000,000 years for energy released in the core of a star to reach the surface and be released as a photon. The journey is a random walk of microsteps of...

I was an undergrad at Cornell studying EE in '86. I was frustrated that I wasn't building anything, just doing lots of math which I enjoy, but it wasn't what I expected. I realized that the classes I was really enjoying were my physics classes, so I changed majors to the applied and engineering...
