From the creators of the popular science show with millions of YouTube subscribers comes the MinuteEarth podcast. Every episode of the show dives deep into a science question you might not even know you had - but once you hear the answer, you’ll want to share it with everyone you know. Our team of scientists digs into the research and breaks it down into a short, entertaining explanation jam-packed with science facts and terrible puns. We’ll tell the incredible story of how monkeys crossed the Atlantic ocean on natural rafts, and we’ll explain why it gets hotter the deeper you dig underground.
