If the inside was a total vacuum, the moment you finished drilling through the 1 mile shell, the vast majority of the planet's atmosphere would be sucked through the open hole at an insanely fast rate.
- hammock 15y agoOK so let's say you install an airlock in between the inner and outer crust.

You seem to suggest that fact that that speed somehow depends on the size of the hollow earth and the quantity of the atmosphere. The pressure depends only on the height of the air column.
