(Phys.org) —Our world is made up of particles so tiny they may actually be points in space. These are quarks, relative newcomers to the physics conversation that were not even postulated until the mid-1960s. Put them together and you get protons and neutrons. Put those together and you get the nuclei of atoms. Put those together and you get you and your universe.
