“We’re on a world,” I told him, not knowing what gaps existed from his reading. “We’re on a world that revolves around a star, which is a giant ball of fire. So enormous that if it weren’t so distant we would all be dead—burned up. We call it the sun—and the sun is what you thought wasn’t nice when it shone so bright on you the other day. But all of those points of light above are also suns, even farther away, and they all have worlds, too.”
