Armageddon.  Apocalypse.  Rapture.  What do such words mean?  This show is about the end of the world, what it will be like according to several ideologies, and why it matters.  Even if you don't believe strongly in a particular religion or political ideology, you probably have an implicit theory of the end (eschatology), and your neighbors sure do.  Sometimes, our views about the end of the world have serious consequences for our life in the world today.  Even though we don't spend much time on the traditional theological conversation, we do mention the distinction between premillennial, postmillennial, and amillennial theologies.
Oh, and Dan also lets us know whether Putin is bringing on a third world war.
