That level foundation has the exact same curvature as the Earth does for that radial distance from the core. This is one of the things I studied in Physics class lo those many years ago. You can take a slab of poured concrete as big as you wish, the example IIRC we used was a football field with a concrete surface that would have padding and astroturf laid on top for football games. Anyhow you have a 120 yard long slab of concrete. You can go over the entire surface with a level or roll marbles on it or whatever method you need to convince yourself it is flat and level. Then you set up the two goal posts exactly perpendicular to the field and you use a square to prove they are at a 90 degree angle to the field. If you put a laser pointer waist high on one of the goal posts and aim it at the opposite goal post on the other end of the field again using the square to make sure the laser is firing at a 90 degree angle where does the spot of light appear on the other goal post? If the slab of concrete is perfectly flat and both goal posts are perfectly straight up at 90 degrees on a flat earth the spot would appear at the same height on the target goal post. However it does not, it strikes the opposing goal post several inches higher because the curvature of the earth makes the other goal effectively a few inches lower on the horizon.
As for link you can post to YouTube or news or even to blogs but don't get carried away and don't try recruiting people to mob some other site.
