> It has been theorized that a self-replicating starship utilizing relatively conventional theoretical methods of interstellar travel (i.e., no exotic faster-than-light propulsion such as "warp drive", and speeds limited to an "average cruising speed" of 0.1c.) could spread throughout a galaxy the size of the Milky Way in as little as half a million years. http://en.wikipedia.org/wiki/Self-replicating_spacecraft http://en.wikipedia.org/wiki/Self-replicating_spacecraft citing http://www.rfreitas.com/Astro/ComparisonReproNov1980.htm http://www.rfreitas.com/Astro/ComparisonReproNov1980.htm
