A proper accounting should consider evolutionary dead ends, and the solar input. Such a system might then, to a degree, resemble an air compressor and a leaky tank powered by solar cells. Remove the power source and evolutionary complexity will devolve back to single cells eaking out what little energy they can until all energy potential is spent. | |

But when we peer out, we are peering at earlier parts of the universe. As such there were fewer supernova to have fused heavy elements to have combined and evolved into intelligent life. | |
