From: Bill Gosper <RWG at MIT-MC> The volume of a colonization bubble can grow at most as t^3, whereas self-reproduction can explode exponentially (a^t), modulo resources. But these resources (stellar matter) appear to have *infinitesimal* average density, being fractally clustered so as to be accessible only as t^1.29. (Mandelbrot: The Fractal Geometry of Nature. W. H. Freeman, 1982.) However, there are more reasons for all this to be moot than our unimaginable unimaginativeness can even begin to overlook.
