Particle seen switching between matter and antimatter at CERN

Yes, but the only ways we know to generate antimatter require a lot of energy. Theoretically it could be an incredibly energy dense "battery" for spaceships or whatever though.

It’s expensive too[1]. “Right now, antimatter is the most expensive substance on Earth, about $62.5 trillion a gram ($1.75 quadrillion an ounce).”

Humans use positrons all the time though, it just turns out (anti)leptons have extremely low mass relative to their usefulness.

Of course they really nail you on the shipping and handling fees.

They're genuinely working on being able to deliver it in the back of a van: https://home.cern/news/news/physics/cern-approves-two-new-ex...
