and then utterly transform the destination

"The effects of a wave of differentiation usually diminish rapidly with distance – simply because physical effects in general do. The sun , from even a hundredth of a light year away , looks like a cold, bright dot in the sky . It barely affects any thing. At a thousand light years, nor does a supernova. Even the most violent of quasar jets, when viewed from a neighbouring galaxy , would be little more than an abstract painting in the sky . There is only one known phenomenon which , if it ever occurred, would have effects that did not fall off with distance, and that is the creation of a certain type of knowledge, namely a beginning of infinity . Indeed, knowledge can aim itself at a target , travel vast distances having scarcely any effect , and then utterly transform the destination ."
