How Do They Make Particles Hit Each Other?

On the border between France and Switzerland is the biggest science experiment ever built. Deep underground are long pipes where they they fire particles smaller than atoms in opposite directions… speeding them up to nearly the speed of light until they smash together. But…HOW do they get such tiny particles to HIT each other? And to see why they built this crazy experiment, subscribe! #shorts #CERN #particle #physics #science
