When the Moon Was Closer, Earth Was Unrecognizable | Documentary For Sleep

Four billion years ago, the Moon hung in the sky thirty times larger than today, driving apocalyptic tides hundreds of meters high and spinning Earth so fast that days were only six hours long. Two billion years ago, when days were eighteen hours, life evolved to an alien rhythm under a looming lunar disk. But the Moon is escaping. Right now. At three point eight centimeters per year—the rate your fingernails grow—it’s drifting away, taking Earth’s stability with it. The Moon isn’t just a beautiful object in the night sky. It’s our climate stabilizer, preventing chaotic obliquity swings that would freeze the equator one century and bake the poles the next. It’s our timekeeper, slowing Earth’s rotation from frantic six-hour days to comfortable twenty-four. It may even be the reason life began—tidal pools concentrating organic molecules, building the first RNA. Born from catastrophe when a Mars-sized planet called Theia collided with Earth four point five billion years ago, the Moon formed from our planet’s own flesh in a matter of hours. We are not separate from the Moon. We are its children. And as it slowly leaves over the next billion years, Earth will wobble alone, seasons will become unpredictable, and the climate that allowed us to evolve will destabilize. This is the story of our temporary companion—why it formed, what it’s done for us, and what happens when it’s gone. We live in a golden age, when the Moon is close enough to protect us but far enough to allow life to flourish. Appreciate it while it lasts.
