Scale Symmetry

Scale symmetry refers to a property where a system's behavior remains unchanged when it is viewed at different sizes or magnifications. Imagine zooming in or out on a fractal pattern; its intricate structure looks similar regardless of the scale. In physics, this concept means that certain laws or patterns stay consistent whether you examine a tiny particle or a large galaxy. It highlights a kind of self-similarity across different scales, suggesting that some fundamental principles do not depend on size, revealing deeper underlying relationships in nature.
