Flat Earth Theory / Re: Perfectly flat bridge vs round earth
« on: December 10, 2013, 02:36:22 AM »
Hey everyone 
If the bridge is perfectly flat, it would also appear perfectly flat. It's just that if you presume a round earth, as you walk along the bridge, the earth's gravity vector will turn more and more, pulling you not just towards but also alongside the bridge. So the bridge would only slope according to the reference frame of up and down as created by gravity.

would it appear flat or would it appear to gradually slope upwards?
