This sounds like the plot of a Young Indiana Jones episode, or maybe Johnny Quest.
William Gadoury is a 15-year-old student from Saint-Jean-de-Matha in Lanaudière, Quebec. The precocious teen has been fascinated by all things Mayan for several years, devouring any information he could find on the topic. During his research, Gadoury examined 22 Mayan constellations and discovered that if he projected those constellations onto a map, the shapes corresponded perfectly with the locations of 117 Mayan cities. Incredibly, the 15-year-old was the first person to establish this important correlation, reported the Journal de Montreal over the weekend. Then Gadoury took it one step further. He examined a twenty-third constellation which contained three stars, yet only two corresponded to known cities. Gadoury’s hypothesis? There had to be a city in the place where that third star fell on the map. —Yahoo! News
