Tomorrow the outlook may change and new methods may dwarf our knowledge and beliefs of today, or convert them into remote history. Soon we may look far beyond the last frontier, now 140,000,000 light years away. We, or our successors, may actually know familiarly the farthest borders of this vast Universe and learn facts about it so astounding that astronomers of today would be nearly unable to comprehend their significance.

– Edwin Hubble, 1927
