Description

For as long as there have been books, there have been rumors of books containing arcane knowledge that have been lost to the ages. When Wilfrid Voynich received a load of books in a sale from the Jesuit Order in 1912, he took a particular interest in one specific text. The book was written in an unknown and seemingly indecipherable language and contained illustrations of plants and constellations that match none known to science. Researching the book, he found that its mysteries went back centuries, with multiple learned people of their eras trying and failing to decode the strange text. Is it the most carefully crafted hoax in history, a medical guide encoded to protect controversial information, or just fanciful gibberish? To this day, it has resisted all modern attempts at decryption. Join us this week, as we examine The Voynich Manuscript!

The Silurian Hypothesis

What if mankind were not the first advanced civilization on Earth? Would we be able to detect the remnants of a culture a million years before our own? A 2018 paper authored by an astrophysicist and a climate scientist asked these questions and presented the evidence we might look for. Massive carbon spikes in the geological record from industrial emissions. Atomic signatures of nuclear activity from a billion years ago. Both sound impossible, except that we have found both of those exactly. We’ll cover the men behind the paper, the hypothesis itself, how the evidence lines up with the biggest anomalies in the geological record, and try to decide if an advanced pre-human civilization really walked the earth. Join us as we examine The Silurian Hypothesis!
