We read some listener emails and comments, which are always great, and discuss those. Then Russ reads an article about Alien Abduction Insurance.
After we laugh about that, Russ reads an article from the excellent website ancient-origins.net, about enormous ancient stone mesoamerican sculptures that have areas of anomalous magnetism embedded in them, and we talk about how the standard model picture of ancient civilizations, with no access to iron, would have no way of figuring out there was magnetism in the stone.... so how did they know it was there?
Kyle talks about the diagrams of ancient mounds and geoglyphs, and how they seem to be attempting to "square the circle" in some of these structures. We also speculate on what it would be like for ancient people to have tried to comprehend the night sky, and what things they may have noticed without all the modern understanding about stars and planets getting in the way.
