If boats or any object go over the curvature of earth how comes we can't see this curvature they are going over or hidden behind?Go to this website with earths curve calculator https://www.omnicalculator.com/physics/earth-curvature scroll down and find the diagram with the curvature and an object hidden from curvature,  where is the big hump of curvature hiding the bottom of objects? Or whole objects? I know you are going to say earth is too big to see the curvature but then objects ain't going over the curvature you can't have it both ways.

If someone can show me on a small scale an object going over a curvature without seeing the tilt or the curvature then that would disprove my point.
