Reply To: size of the earth

They quote Rashi in Gittin as saying that the world is flat and I believe there is a T’shuvas Harashba that says so also. I have never seen it inside though I heard it’s a Machlokes in the Yerushalmi whether it’s flat or round. I once tried to give whether the Earth is flat or round as P’shat in the Machlokes in Megillah whether Hodu and Kush were on opposite ends of the Earth or next to each other (if they’re next to each other then ruling over from one to the other is ruling over the whole world if it’s round). We Pasken that it’s round, obviously.
