02 / THE LONG WAY DOWN
Every layer
has a story.
Follow the light. The air thins, the ocean closes overhead, and the rock gives way to a moving sea of metal.
A note on scale
The vertical spacing is deliberately non-linear: kilometers of deep mantle are compressed, while nearby landmarks are spread apart so they remain legible. Figures are real; the live counter interpolates between the marked reference points.
03 / THE CENTER
A quiet
core.
6,371 kilometers from the surface, gravity draws inward from every direction. The inner core is a solid sphere inside a liquid metal shell.
