## Resource

Your body may feel solid, but physics tells a different story. In every second, trillions of particles—including neutrinos, cosmic rays, and human-made radio waves—pass straight through you without interaction. Even the human body itself emits tiny amounts of radiation from naturally occurring elements like potassium-40. In this episode, we explore how electromagnetic forces and quantum physics create the illusion of solidity, revealing that we are mostly transparent to the universe—interacting with only a This episode includes AI-generated content.
