From Fermilab https://twitter.com/Fermilab on Twitter: When a proton and antiproton collide at nearly the speed of light, they can produce a #TopQuark and anitquark. These two heavy, unstable particles decay into lighter particles. The decay chain can produce bursts of light particles that are observed as jets. #TopQuark25 https://twitter.com/Fermilab/status/1234549290820866048/photo/1 https://chirp.cooleysekula.net/attachment/63260
