From Thunderstorms to Black Holes: 4 Natural Particle Accelerators

The video explores particle accelerators, both man-made and natural, such as thunderclouds, Van Allen belts, and cosmic phenomena like supernovas and black holes. It explains how these accelerators work, their role in producing high-energy particles, and their significance in understanding fundamental physics. The video also discusses the potential of using natural accelerators for scientific research.
