Yes, the question is physically impossible. Gravity wins. Everything stays together. Indeed, the Earth is, right here, right now, 'broken'. The continental plates drift about over the more or less fluid inner crust, the mid-ocean ridges serving as spreading centers. The Earth, it ain't rigid at all. It's just held together by gravity. It can't break, it's already a pile of (differentiated) rubble.
A fun trick question is 'What's the largest rock known?' Answer: 'The Earth.' All four of the gas giants probably have larger rock cores, but it's not known for sure.
Good thinking question, anyhow. Regards, John M.
I'm not a hardnosed mainstreamer; I just like the observations, theories, predictions, and results to match.
