Abstract
In this letter we present an idea which reconciles a homogeneous
and isotropic Friedmann universe with a fractal distribution of
galaxies. We use two observational facts: The flat rotation curves of
galaxies and the (still debated) fractal distribution of galaxies with
fractal dimension ![[FORMULA]](img1.gif)
. Our idea can also be
interpreted as a redefinition of the notion of bias.
Key words: large scale structure of
universe 
cosmology:
theory
cosmology: dark
matter
galaxies: general
