88. Ylem

Emily and Kyle answer the biggest questions of the cosmos, as they discuss the meaning and origin of the word ylem.

Our hosts talk about how this word relates to matter and the elements, both in the works of Aristotle and other ancient thinkers, and in the Periodic Table. They chat about some quirks of grammar and pronunciation, but then they dig into the real cosmic center of this episode.

Always excited to talk astronomy, Emily and Kyle head back to the earliest thoughts on the Big Bang. Long before Stephen Hawking contributed to the Big Bang Theory, there was Lemaitre and Hubble and several others. And ylem, it turns out, might just have been the most important substance in the creation of the universe.
