Alfred Centauri Posted August 15, 2010 Report Share Posted August 15, 2010 (edited) Since neither sound credulous, it would amount to Galileo's observation of comparing infinities to one another for greater than or less than as essentially meaningless. Food for thought... If there is in fact a metric expansion of space, entities can, in a certain sense, be "infinitely" far apart, i.e., they can become causally disconnected, unable to interact with each other by any possible means. Consider a couple of examples of how large distances are measured, e.g., RADAR or laser ranging of the moon. Over very large distances and in a metrically expanding space, there is the possibility that the radio or light wave never "catches up" with the receding entity. In effect, that entity is "infinitely" far away in the sense that no physical thing, even light, can ever get "there" from "here".
