Thanks for the comparison. At the moment Hello is highly dependent on the underlying results returned by Bing, which makes it non-deterministic. I just tried your question and got an answer that seemed more plausible. > why is the earth flat > The Earth is not flat. It is a spherical surface with a horizon that is closer when viewed from a lower altitude, and it casts a round shadow no matter which direction it is pointed. This shape causes a number of phenomena that a flat Earth would not, such as ships disappearing over the horizon progressively, the coastline or mountain appearing normally, upside down, and broken into pieces from across Lake Michigan, and stars being visible from different locations on Earth at the same time. Additionally, surveys from all over Earth show that its shape is everywhere locally convex, confirming that it is very close to spherical.
