Cold Dark Matter. The universe is made up of at least two kinds of matter. Primarily, there's the material we can detect, which astronomers call "baryonic" matter. It's thought of as "ordinary" matter because it's made of protons and neutrons, which can be measured. Baryonic matter includes stars and galaxies, plus all the objects they contain.This mysterious energy makes up 80 percent of all matter in the universe.
