This is where Verne’s journey would end in a fiery death. The outer core is liquid. It is a hurricane of molten iron and nickel swirling around the inner core. This motion creates Earth’s magnetosphere, which protects us from solar winds. If you could stand at the top of the outer core (you can’t, you’d float and melt), you would experience gravity similar to Earth’s surface, but the pressure would be 1.3 million atmospheres.

The project was halted because the heat became unmanageable—reaching 356°F (180°C)—turning the rock into something with the consistency of plastic. It turns out the Earth's "gatekeepers" are heat and pressure, not dinosaurs. Why the Journey Still Matters This is where Verne’s journey would end in a fiery death
Verne brilliantly uses actual geological theory of his time. The travelers encounter three distinct layers of reality: A massive storm
But the earth is not a quiet host. A massive storm, fueled by the cavern’s internal electromagnetism, seized their raft. They were tossed like splinters until they were spat out onto a new shore, far from where they started.
