The ancient Greeks concluded the Earth was round more than 2,000 years ago, but that wasn’t the end of the Earth-shape debate.
In 1692, astronomer Edmond Halley said the Earth was a shell with a thick crust. Others today believe a version of this, saying the Earth is hollow and has a secret entrance near either the north or south poles. The inside is said to hold anything from a smaller Earth to a smaller sun to a utopian alternate universe.
