Personally, I've not once read any literature in peer-reviewed scientific papers that discusses any such notion.
What else have you not done?
I've also
not accepted any of Samuel Rowbotham's claims about his purported flat earth, and I've
not given any credence to his poorly-contrived experiments on the Bedford canal. I've also
not flown to the moon to see the earth's total sphericity myself, (but I
have seen it from an aircraft at around FL45).
