When we take things apart, we can learn how they work. Physicist Clifford Johnson explains how we break down all objects into elementary particles of matter and forces. Patterns have been identified with the particles, the existence dark matter has been suggested, and gravity's unexpected behavior at the quantum level all contribute to string theory. Studying the minuscule string theory can help us understand the vast structure of the universe! Strike a chord with your physicists by sharing this lesson on string theory.
