According to George Stuart, on Stela 1 at the ruins of Coba in Quintana Roo appears the rare expanded date for the Mayan creation, which is so phenomenally large that 40,000,000,000,000,000,000,000, 000,000 years--that is 40 octillion years--would have to pass away before the cycle would come around again. This interval is approximately equal to the fifteen-billion-year span that separates us from the cosmic "big bang" multiplied almost 3,000,000,000,000,000,000 times! [George E. Stuart, "The Calendar," in Gene S. Stuart and George E. Stuart, Lost Kingdoms of the Maya (Washington, D.C.: National Geographic Society, 1993), p. 177.]
