I had a dream that the moon’s orbit was decaying a little bit, and as a result, at the next solar eclipse, gravitational lensing was going to cause the moon to act like a magnifying glass and the Earth was going to act like an ant with the sunlight magnified at it. So I ran some computer simulations and figured out how to solve the problem: Everybody on the Earth was supposed to take everything reflective they had and point it at a certain spot on the moon when it was visible during the day. Ablation would cause the moon to accelerate back into a safe orbit for the next couple tens of thousands of years.
