Is the world flat ,how would i know if it wasn't?

Answer 1

Well if you don't trust modern science, satelite pictures, tv, and you don't want to make matematical and astronomical measurments, their is always the ultimate way to make sure the Earth isn't flat. Just start walking in one direction, climb over some mountains, swim over the oceans, and some day hopefully you will return home, the same place you've started your journey.

Answer 2

The modern stuff -- pictures from outer space -- doesn't count. You're no astronaut. The Greek stuff (Eratosthenes) only works if you're a scientist who knows about angles and things.

That leaves the ship sailing away from port. It disappears below the horizon ("hull down"). That works for ordinary people like you & me -- but only if you live by the sea.

If you stand on the highest hill (or mountain) around, and look as far as you can in any direction, even using binoculars, there's a limit as to how far you can see. The higher up you are -- even in an airplane at 30,000 feet -- the farther you can see, but there's a limit nonetheless.

By looking around in all directions, it might seem that you're at the center of the whole world. But you know that's not true, so the world must not be flat.

Does this make sense to you?

Answer 3

The other way that ancient Greeks showed the earth was round was by measuring the angle of the sun above the horizon at noon, then traveling north or south an repeating the measurement of that angle.

Answer 4

Send an e-mail to the astronauts/cosmonaut aboard the International Space station. They'll tell you, because they have seen it with their own eyes -- everyday!

Answer 5

Satellite images are pretty convincing...
