Question: What in this world are made up of sub-atomic particles?

Keywords: ,

  1. Well… *everything* in this world is made up of subatomic particles. Everyday matter is made up of atoms, and these are made of protons, neutrons, and electrons, all of which are subatomic by definition. And then protons and neutrons are made up of quarks.

  2. Have to agree with Matthew on this one. By definition, I suppose a sub-atomic particle must be part of an atom, and everything (I think?) is made of atoms, so everything must be made of sub-atomic particles. But maybe there are some sub-atomic particles that are not parts of atoms?

  4. I think “everything” covers it very nicely!

  5. Everything is made up of sub-atomic particles! There are also sub-atomic particles that are not part of atoms; what we call cosmic rays (particles that rain down on Earth from space) are made up of various different kinds of sub-atomic particles, including from protons and electrons. When they reach the Earth’s atmosphere they collide with the atoms and molecules to form weird things like pions and kaons. These decay into muons which is often what we detect when they reach the surface.
