For the whole world to see "posthuman" will not answer my question because he knows the earth is not a globe.
This whole discussion here has proven to everyone with out any doubt the earth is flat. People who claim to believe the earth is a globe will not let us know how long of a distance we would be able to see from on top of a tall mountain till the curvature of the earth dips below the horizon line?
If you truly believe the earth is a globe, If you stand on a tall mountain with a view of great distance, how long of a distance do you believe you should be able to see till the curvature of the earth dips below the horizon line?
