In 1704, Isaac Newton Predicts the World Will End in 2060

Josh Jones at Open Culture.

"...many of Newton’s general principles would seem totally inimical to the naturalism of most physicists today. As he was formulating the principles of gravity and three laws of motion, for example, Newton also sought the legendary Philosopher’s Stone and attempted to turn metal to gold. Moreover, the devoutly religious Newton wrote theological treatises interpreting Biblical prophecies and predicting the end of the world."
