- Mandelbrot in his classic book, "The Fractal Geometry of Nature" (Freeman,
- San Francisco, 1982), talks about "Fractal Universes." I believe the term
- is "Fournier Universe." The idea is that the matter in the Universe is
- distributed in a fractal manner with approximate self-similarity. The
- fractal dimension of the matter in the Universe is the order of 1. Spheres
- centered on the Earth, for example, contain an amount of matter that is
- roughly proportional to their radii, because of the way the matter is
- clumped around planets, stars and galaxies. This relates to Olbert's
- paradox which is why the sky is dark at night. If stars were distributed
- uniformly in a 3-D universe, the night sky should be as bright as the day
- sky.
