Abstract
We suggest a geometrical model for the distribution of luminous matter in the Universe, where the apparent dimension, , increases linearly with the logarithm of the scale . Beyond the correlation length, , the Universe is homogeneous, and . Comparison with data from the SARS redshift catalog, and the LEDA database provides a good fit with a correlation length Mpc. This type of scaling structure was recently discovered in a simple reaction-diffusion “forest-fire” model, indicating a broad class of scaling phenomena.
