I like looking into people's theories about earth, even if it's "taboo" it just makes it more fun tbh. I know this has been disputed and said not to be a real quote from Aristotle but it's still a valuable quote 'the mark of an educated mind is to entertain a thought without accepting it' - with that said, hollow earth is a cool theory too. I think the most important thing to take from these debates it that we don't know everything and we definitely aren't being told everything.
