The Silence Between the Signals
Jul 29, 2026 · 39m
Summary
The hosts discuss early radio mysteries, including unexplained signals heard by Tesla and the host’s grandfather, which were later attributed to atmospheric phenomena rather than aliens. They then explore the "Gallaudet 11," deaf volunteers who helped NASA study motion sickness and balance in space due to damaged vestibular systems. The episode also features segments on awkward business names and sponsor reads for Zenni and Quince.
