All made from...
There are many things in the universe, from a banana to an entire galaxy, but what if I told you everything was made of the same material (kind of)? You wouldn’t believe it, would you? Well, it is true! Everything is made of molecules. Molecules are made of atoms, and those are made of protons, neutrons and electrons, and protons and neutrons are made of quarks. What are these things and is there a limit to how small things can be?
Starting smallest...
Let's start with quarks. Quarks are totally weird. For simplicity, try to picture them as colored marbles. They are too small to see with a microscope, but even stranger, they never occur by themselves, but only as part of other particles. There are different kinds (flavors) of quarks, six in total, of which five are stable.
