Look up at a full moon on a clear night and you are staring at a face that has been punched, gouged, and battered for 4 billion years. Those dark patches are vast basins blasted open by impacts so colossal they reshaped a world. The lighter highlands are pocked and pitted, crater upon crater, each one a frozen record of a collision that happened long before humans walked Earth. Unlike our own planet, the moon has no weather to smooth things over, no rivers to fill the hollows, and no wind to soften the edges. What hits it stays.
