string theory

String Theory is a way of understanding the universe that seeks to unite the laws of physics with the smallest particles that make up everything in the world. It is based on the idea that everything in the universe is made up of tiny vibrating strings, rather than the particles that have been traditionally used to explain things. String Theory suggests that these strings vibrate at different frequencies, which help determine the properties of the particles they make up. A good way to think of String Theory is to imagine a guitar string. When plucked, it vibrates and makes a sound. Different notes or frequencies are achieved by tightening or loosening the string. Similarly, String Theory suggests that the way strings vibrate determines the properties of the particles that make up the universe. Fun Fact: String Theory is sometimes called the Theory of Everything because it seeks to explain all of the forces in the universe.
