String theory describes fundamental particles from "summary" of A Breif History of Time and the Universe in a Nutshell by Stephen Hawking
String theory is a revolutionary idea in the field of physics that attempts to describe the most fundamental building blocks of the universe. According to this theory, the basic entities that make up everything in the cosmos are not point-like particles, as previously believed, but rather tiny, vibrating strings. These strings can oscillate at different frequencies, giving rise to the various particles and forces that we observe in nature. One of the key insights of string theory is that the different particles we see in the universe are actually just different modes of vibration of the same underlying string. In other words, electrons, quarks, and photons are all manifestations of the same fundamental object, just vibrating in different ways. This unification of seemingly distinct particles is a major achievement of string theory and has the potential to revolutionize our understanding of the universe. By describing particles as strings rathe...
