Hello,

I just joined this site. I am not a flat-earther so I hope it's OK that I'm here. I wanted to ask a few questions regarding the shape of the earth. First, if you leave from any point on the earth, say in a plane, and continually travel in a straight line east will you not eventually end up where you started? If you did this only once from one location you would only have proved that at least the earth was disc shaped. If you went further north and/or south and did the same thing you would have proved the earth was at least cylindrical. If you did this numerous times at different latitudes and fairly consistent elevations you could soon get a pretty good idea as to whether the earth had the characteristics of a sphere by measuring your distances. I have no idea what flat-earthers believe regarding the magnetic field, but you could do the same thing by travelling in a straight line along a line of longitude. Depending on where you started, your compass would likely change directions a couple of times.

Also, if you stand on the shore at the ocean and watch a ship coming or going you will see it rising into view or falling away from view respectively. This becomes more evident if you have some binoculars or a telescope.

These are things that aren't that hard to do, and in fact have been done. They do not require any input from NASA or any other government organization.

Since these are such simple suggestions, I'm sure they've been answered. However, I don't know your answer to these questions since I am new to this site, but I would like to. Hence, this post.
