The Supermassive Podcast

In yet another mind-bending episode, we take on antimatter – What is it? How do you make it? And can you use it to power a spaceship? Dr Becky, Izzie and Dr Robert Massey (he’s back!) are joined by Professor Jeffrey Hangst from CERN in Switzerland, home of an antimatter factory. We also discover that every time you eat a banana, antimatter is being destroyed.
