Description
Just when the mysterious dimming of nearby giant star Betelgeuse is explained, a more distant giant star was almost completely blocked out. We discuss the very different explanations for these two stellar events, and we check in with updates on metallic asteroid Psyche and other Astroquarkian asteroid news.

Gödel's Incompleteness Theorems
Do you know a know-it-all? Some smug smarty-pants in your life who always has an answer for everything? Then maybe you want to get yourself a pair of Gödel's Incompleteness Theorems. The next time it seems like they're inventing an answer out of thin air, you can remind them that no consistent system of axioms whose theorems can be listed by an algorithm is capable of proving all truths about the arithmetic nature of natural numbers--in other words, you can't know it all. Remember, the best way to never be wrong is to know when say "I don't know" then go find out if you can. Gödel's Incompleteness Theorems, be all you can be.
