The Return Of The Discarded Billionaire Ex-Wife
Sometimes the library was four people in a room all working in the same quiet, which was a different thing from loneliness and the opposite of it.
One Sunday morning Edmund looked up from the floor and said: "Dad. Why do things fall down instead of up?"
“Gravity," I said.
“Yes, but why does gravity go down?" he said.
“It goes toward mass," I said. "The Earth is very heavy. Gravity pulls toward it."
He considered this. "So if there was something heavier than the Earth above us things would fall up?"
“In theory," I said.
He wrote something in his notebook.
Eleanor looked up from her desk. "That is not practically achievable in our current situation," she said.
