Dark matter is one of the universe’s greatest mysteries. It’s the invisible force that glues galaxies together and sculpts cosmic structure. In this episode, we trace the journey of discovery from massive objects in the Milky Way to particle-scale experiments designed to reveal what dark matter really is. From gravitational microlensing to cutting-edge detectors at Lawrence Livermore National Laboratory, scientists are pushing the limits of technology and imagination to uncover the unseen and understand the mass that makes up most of our universe.
