Columbus did the most to prove the earth was shaped like a ball. He did this by sailing to America, and proving to Europe that the world was not flat. Edit: a lot of people think that, but it was established by the Ancient Greeks about 1800 years earlier.
Cartographers an represent the spherical Earth on flat paper by making a projection, which is like casting shadows from the spherical world onto a flat piece of paper.
A boat at sea, alone, does not prove that is earth is round. However, boats can be used to prove that earth is round. This is because if the earth was flat, eventually a boat would sail to the end of earth and fall off the edge. This has never happened, so it can be inferred that the earth is round. Also, a boat can sail all the way around the world and end up right where it started, which proves that the earth is round.
A sun dial is a graded flat disc, with an upright spike in the middle of it. The spike will throw a shadow that will move across the graded disc as the sun moves across the sky. If the sun dial is correctly aligned, the position of the shadow will tell you what time it is.
The earth's gravity field makes everything push into the earth like a bubble arround the planet. This makes it seem like the earth is flat.

He hoped to bring that if you settle East you can make it to Asia.Which that didn't happen because he fount a new world (North America) and he didn't prove that you can settle East and make to Asia.But he did prove that the WORLD is NOT flat is round or he would of made it to Asia. Hope this helped:)
so that he could find goods and also so he could prove that the world was not flat.
Flat Out - To collapse, to prove a failure.
Maybe someone who is trying to prove that and doesn't know the right answer
The earth is flat
The earth is flat
Yes, it is. Satellite imaging will negate the hypothesis and prove that Earth is round, not flat.
He was trying to prove that the earth was flat
