Old-school Cometary Theory: Above or Below the Moon?

5 Jan

How Do We Know if Something is “Above the Moon”?

Where do comets come from? Other than the sins of human beings rising every hour until the stench and horror turns into a comet (a reference to Andreas Celichius, The Theological Reminder of the New Comet, 1578).

So, Oort Cloud? Human sin? It could go either way.
