Lori Gardi aka Fractal Woman presents more insights into the fractal self-similar behavior of nature. This time she compares magnetic isopotential (or equal strength) field lines with black holes as well as the famous fractal Mandelbrot Set. The geometries of all three are very similar and raise the possibility that the "strong gravity" associated with black holes may in fact be just scaled up magnetism.
Here is a corresponding paper she had written describing the similarities between the geometries of black holes, spiral galaxies, and particle trajectories with basic iterative fractal mathematics.
