why does it matter if the earth is round or flat

On the clearest of days, the only restriction to one's range of sight is the horizon. there's a horizon, meaning that the surface that one is observing from is not an infinite plane. This is a question that has been asked for many years, and there are some very intuitive, and some not-so-intuitive answers. Paul Walorski, B.A., Part-time Physics/Astronomy Instructor Once again, the only solid that always projects a round shadow is a sphere. Every time that shadow is seen, its edge is round. When a full Moon occurs in the plane of Earth's orbit, the Moon slowly moves through Earth's shadow. The geometry of a lunar eclipse has been known sinceĪncient Greece. One of the oldest proofs of the Earth's shape, however, can be seen from the ground and Every picture ofĮarth ever taken shows only a circular shape, and the only geometric solid which looks like a Astronauts and space probes have done just that.

How can one prove that the world is round?Īnswer Now that we have access to space, the easiest way to prove the Earth is spherical is to leave it and view it from a distance.
