Is the universe made of music? The logic of string theory.
In short: This animated explainer breaks down one of physics' most ambitious projects: a theory that suggests everything in existence is composed of tiny, vibrating strings. It explores why our current laws of physics are broken and how this theory attempts to fix them.
String theory proposes that the fundamental building blocks of reality are not point-like particles, but microscopic vibrating strings. Much like different notes on a guitar, these vibrations create the various particles and forces we observe. The theory aims to be a "theory of everything" by unifying the four fundamental forces of nature, specifically addressing the conflict between general relativity and quantum mechanics.
The theory originated in 1969 with a formula by Gabriele Veneziano. To function mathematically, it requires the existence of extra dimensions—ranging from 9 to 25. While highly theoretical, scientists are looking for experimental evidence using tools like the Large Hadron Collider.
