States of Matter: Facts. Matter is all around us. Matter is the air you are breathing. Matter is the computer you are reading from now. Matter is the stuff you touch and see. And it is more. Matter is defined as anything that has mass and takes up space.
For other uses, see Matter (disambiguation). In the classical physics observed in everyday life, matter can be defined as any substance that has mass and takes up space, or as any substance made up of atoms, thus excluding other energy phenomena or waves such as light or sound. Observable physical objects are said to be composed of matter.
