A Modest Proposal: Let’s Change Earth’s Orbit

A Modest Proposal: Let’s Change Earth’s Orbit

Credit: Britt ScharringhausenHere, Teq is Earth’s temperature, T ☉ is the sun’s temperature, R ☉ is the sun’s radius, X is the distance to the sun, and A is Earth’s albedo, or reflectivity. All we have to do is find a way to move all 5.972 septillion kilograms of Earth’s mass farther away from our star. Using another back-of-the-envelope calculation, Scharringhausen finds that 5 x 1031 joules could push all 5,972,000,000,000,000,000,000,000 kilograms of Earth’s mass three million kilometers out from its present orbit. What if instead of getting rid of our natural satellite altogether, we only change its orbit around Earth? We should immediately prioritize pouring all our energy into changing Earth’s orbit, starting now and lasting forever.
