A slowly rotating 3D hologram of the Moon hung in the air in front of the nearest alien. "This Moon of yours exposed your history. It should have been obvious to us from the beginning. The Moon's mass is only 1.2 percent of the Earth while being 25 percent of the diameter. Your Moon is artificial. The mantle is filled with space, like the space in this ship, not empty but hollow."

"Dude! Are you nuts? The Moon is just the Moon. I don't understand. What do you mean exposed us? What does this have to do with me?" Met replied.
