This is a video on one of the most expensive substances on Earth – antimatter. Did you know that an antimatter explosion can destroy the Earth in just a few seconds? It’s the rarest, most expensive, and potentially the most dangerous material on Earth. This YouTube video by Physics Girl features a tour of an antimatter factory in Europe. We have included this video on antimatter in this list because it shows viewers how and where the most expensive thing in the world is created!
