> Perhaps the simplest explanation of the Fermi Paradox is that potential growth for a starfaring civilization is geometric (being a sphere ultimately limited by the speed of light) while growth rates are exponential. And exponential will ultimately "win". I read a paper within the last few months that used simulated expansion into a galaxy to debunk that idea. The fallacy is that growth is continuous and ceases simultaneously across a civilization. The (simulated) reality is that only a tiny percentage of frontier colonies need to survive to prevent extinction and eventually resume growth. I wish I could find the paper. Anyone know the one I'm talking about?
