~nCERN: First successful road transport of antimatter.
Claire, The Ultimate Worrier@nblr damn I still thought antimatter was still only a theoretical thing that must exist somewhere in the universe but no one is sure where

@waitworry @nblr that's dark matter. antimatter has been known for pretty long, positrons are naturally emitted in certain types of radioactive decay (β+ decay), and heavier antimatter can be found in cosmic rays.
