Radiolab

In 1908, on a sunny, clear, quiet morning in Siberia, witnesses recall seeing a blinding light streak across the sky, and then… the earth shook, a forest was flattened, fish were thrown from streams, and roofs were blown off houses. The “Tunguska event,” as it came to be known, was one of the largest extraterrestrial impact events in Earth’s history. But what kind of impact—what exactly struck the earth in the middle of Siberia?—is still up for debate. Producer Annie McEwen dives into one idea that suggests a culprit so mysterious, so powerful, so… tiny, you won’t believe your ears. And stranger still, it may be in you right now. Or, according to Senior Correspondent Molly Webster, it could be You.EPISODE CREDITS Reported by - Annie McEwen and Molly WebsterProduced by - Annie McEwen and Becca Bresslerwith help from - Matt KieltyOriginal music and sound design contributed by - Jeremy Bloom, Annie McEwen, Matt KieltyMixing by - Jeremy Bloomwith dialogue mixing by - Arianne WackFact-checking by - Diane Kellyand
