How do we know the Earth is round?
Teachers have told us that the Earth is round like a ball. Scientists have advised us that the Earth is round. Astronauts who have been to the Moon have instructed us that the Earth is spherical. They took pictures. And yet, when you walk outside, the whole lot appears completely flat. What's the deal? Are teachers trying to trick us? Are the pix from the space faux? And is there any manner to even know for yourself? I imply, except you come to be an astronaut and go to space, it appears not possible to ever recognize this for yourself.
