New SETI blog post:

Searching for Nonfractal Signatures

Geological processes are inherently fractal. Unlike artificial sites such as cities and farms, defined by uniformity and harsh angles, natural landscapes repeat themselves on multiple levels. A mountain, for instance, is "repeated" in any of the countless rocks that litter its slopes. (Weirdly enough, we seem to inhabit a massive fractal: orbiting planets recall the structure of atoms; galaxies themselves bear a passing structural similarity to their constituent star systems.)
