Episode notes

I think it's actually not that hard to imagine we are the only civilization in the galaxy right now living. But there may be very many extinct civilizations. And so I've been thinking a lot recently about how would we send a message to other civilizations in the future? Because that act of thinking seriously about the engineering of how your designer would inform us about what we should be looking for could be our best chance, quite frankly, of ever making contact.
