Question: What is the smallest thing in the world

Sarah Hunak answered on 15 Nov 2016:

Atoms – what everything is made up of, are very small, so that you can’t see them with just your eyes and you need to use a special type of microscope, then there’s the things that atoms are made up of, electrons, protons and neutrons, and then there’s the quarks that these are made up of. They are the smallest things we know of, but it absolutely blows my mind how small these things are!
