In this episode of *Science Quickly,* we share part two of our crossover with Vox’s *Unexplainable* in which we explore one of the universe’s biggest mysteries: dark matter. Host Noam Hassenfeld talks with *Scientific American* senior reporter Joseph Howlett, a former physicist who spent years searching for dark matter deep beneath an Italian mountain. Their conversation traces the decades-long hunt for the invisible substance thought to make up most of the universe’s matter and explores an even deeper question: What if some mysteries are beyond science’s reach?
