Edmund Halley, an English astronomer and mathematician, theorized that the Earth is hollow and that there are inner concentric layers below the crust that float in gas. He said that the core was about the size of a planet Mercury and that these layers were inhabited as well. Today, science confirms that the outer core of the earth is even bigger than the planet Mercury. Based on seismological studies, the outer core of the Earth has a radius of 3 400 km; Mercury has a radius of 2440 km.

Edmund Halley, an English astronomer and mathematician, theorized that the Earth is hollow and that there are inner concentric layers below the crust that float in gas. He said that the core was C2 about the size of a planet Mercury and that these layers were inhabited as well. Today, science confirms that the outer core of the earth is even bigger than the planet Mercury. Based on seismological studies, the outer core of the Earth has a radius of 3 400 km; Mercury has a radius of 2440 km.
