Part 3/9:
One such theory is string theory, famously described as "crazy." Its foundation lies in a radical idea: that every subatomic particle is actually a tiny vibrating string, rather than a point-like particle. These strings vibrate at different frequencies—like musical notes—and these vibrations correspond to different particles, such as electrons or quarks.
Think of the universe as an enormous symphony, where each note represents a subatomic particle. The physical laws we observe are akin to the harmonies produced by this cosmic orchestra. Chemistry, then, becomes the interactions and bumping of these strings into each other, forming molecules and complex matter.
