ELI5 that the earth is definitely not hollow, not even a bit, not even large caverns 1000km deep
How can it be a mathematical fact that the earth is not hollow (other than man made mines and the like).
To my understanding, the math doesnt even leave the possibility of very large caverns 1000km below the mantle to exist.
The deepest we have ever drilled was 22km deep? And the Schiehallion experiment seems to mathematically prove that simply due to gravity, there cannot be any i.e. massive tunnel network.
