scale relativity
Scale relativity is a geometrical and fractal space-time theory. The idea of a fractal space-time theory was first introduced by Garnet Ord, and by Laurent Nottale in a paper with Jean Schneider. The proposal to combine fractal space-time theory with relativity principles was made by Laurent Nottale. The resulting scale relativity theory is an extension of the concept of relativity found in special relativity and general relativity to physical scales (time, length, energy, or momentum scales). In physics, relativity theories have shown that position, orientation, movement and acceleration cannot be defined in an absolute way, but only relative to a system of reference.
Noticing the relativity of scales, as noticing the other forms of relativity is just a first step. Scale relativity theory proposes to make the next step by translating this simple insight formally in physical theory, by introducing explicitly in coordinate systems the “state of scale”.
To describe scale transformations requires the use of fractal geometries, which are typically concerned with scale changes. Scale relativity is thus an extension of relativity theory to the concept of scale, using fractal geometries to study scale transformations.
The construction of the theory is similar to previous relativity theories, with three different levels: Galilean, special and general. The development of a full general scale relativity is not finished yet. However, the existing progress and results already have consequences for the foundations of quantum mechanics, particle physics, and high energy physics. Furthermore, empirical predictions in physics, astrophysics, and cosmology have already been validated, most often with a high precision, or highly statistically significant results.
