A hundred years later, the great French mathematician and skeptic Pierre-Simon Laplace described his new orbital theory to Napoleon and supposedly quipped of God’s role, “I have no need for that hypothesis.” In fact, it is bad theology to reduce God to merely a gap-filling hypothesis. Only recently, however, have we learned that, actually, planetary motions may sometimes not be so stable after all. One of the pioneers of studying chaos theory in celestial dynamics is Jack Wisdom, an MIT professor (and MacArthur “genius”) who is visiting the Vatican Observatory this month. He’s working now on modeling the complex interaction between the Moon’s orbit and spin with the spin and orbit of the Earth. It’s all tied to the larger issue of the origin of … Continue reading →
