The Controversial States of Matter
Matter is anything that has mass and takes up space. Hopefully, you are doing more than just taking up space (except you astronomy majors). Everything is made up of matter. Except, of course, non-matter, which is anything that does not take up space or have mass. Like light, energy, love, kindness, thoughts.
So, what’s the matter?
Solid. Liquid. Gas. Plasma. They are you, and you are them.
