Funny enough, my boss has a PhD in Evolutionary Biology. She never tells people because they start referring to her as Doctor, and she hates that. I don’t think I’ve actually ever heard her bring it up on her own.

And that can’t be good for the oven.

Thank you for reposting it! I’ve been looking for resources like these.

“The use of words expressing something other than their literal intention. Now that is irony!” - Bender Bending Rodriguez

This is an often misunderstood aspect of the sun. The sun doesn’t need to pull oxygen into itself to burn. It just does a bit of fusion magic!

When a star is dense enough it starts to fuse Helium together through a process called the “triple alpha process”; which results in Carbon! From there it’s pretty direct for the star to fuse one more Helium to the Carbon via stellar nucleosynthesis to create Oxygen!

So you see, the Sun doesn’t need to draw Oxygen from space. It just makes its own!
