Ever heard of a ghostly particle that can pass through the entire planet without a trace? In this episode, we journey a mile underground to explore DUNE, the Deep Underground Neutrino Experiment, a colossal detector built to catch these elusive particles. Join us as we unravel the mind-bending mystery of how neutrinos "oscillate" — changing their type, or "flavor," mid-flight. We break down this complex quantum phenomenon with a surprisingly simple analogy (hint: it involves ice cream!) and follow the 800-mile journey these particles take from Illinois to South Dakota. Tune in to discover how scientists are using this epic experiment to unlock the deepest secrets of our universe.
