Episode 356

A truck carrying antimatter has been driving around the campus at CERN, home of the Large Hadron Collider. But why are scientists transporting this delicate and extremely expensive substance?

Antimatter is regular matter’s counterpart, first theorised in the 1920s. Producing and storing it has proved difficult, as it’s prone to annihilating the moment it meets its opposite half. But CERN scientists found a way - and it’s the only facility on Earth able to create these particles.

Carrying just 92 antiprotons, this truck experiment is the first step in setting up an antimatter delivery service, allowing scientists to send little pieces of antimatter on trucks to labs around Europe.

To discuss why an antimatter delivery service is even needed, Rowan Hooper and Penny Sarchet are joined by Alex Wilkins, who recently visited the lab and saw the antimatter factory in person. We also hear from the new director-general of CERN, Mark Thomson.
