Nothing expands the mind like the expanding universe. The music of the spheres is a nursery rhyme, a jingle to set against the majestic chords of the Symphonie Galactica. Changing the metaphor and the dimension, the dusts of centuries, the mists of what we presume to call “ancient” history, are soon blown off by the steady, eroding winds of geological ages. Even the age of the universe, accurate to the fourth significant figure at 13.72 billion years, is dwarfed by the trillennia that are to come.- Richard Dawkins@Englishnutsbolts
