people like albert einstein, stephen hawking, and other people why havent they said the earth is flat? I understand that the earth is flat myself, but I dont understand why they havent had any history with a flat earth.
It's simple. At the time due to things such as the moon landing which convinced a lot of people that the earth was a sphere they feared that their ideas would be rejected, so they didn't release this knowledge to the public.
Einstein was already the most revered physicist of his time before the first human craft capable of getting into orbit was even dreamed off. If he had said the earth was flat if he had thought so, everyone would have reviewed all of humanity's scientific achievement before that time to see if he was correct of not. He was also very dead as at the time of the moon landings and so could not have been afraid of public opinion.
Fact is Einstein knew the earth was a heliocentric sphere as his theories on gravity show that very well. He saw gravity as a bending of spacetime created by the masses of bodies hanging in said space time.
It is interesting how flat earyhers keep sayin “we are told from birth the earth is round” when in reality all the theories and observations that point to, describe and show a spherical earth is available for anyone to review. If Einstein said the earth was flat, the scientific community would have said “prove it”. If he submitted his proofs, they would have reviewed it. By “they”, I don't mean some hidden faceless group as flat earthers seem to think. I mean hundreds of thousands of science students, lecturers and practitioners all over the world. They would have examined Einstein's statements (as they did regarding his theories) and if he was found to be right, we would all be teaching flat earth right now. If he was found to be wrong, that's a lot of crow fella would have been made to eat.
Einstein KNEW the earth was a sphere as it is in truth.
