My apologies if similar topics have already been discussed. I get buried in a sea of information when reading through the threads!
I have been attempting to provide definitive proof to a friend that the Earth is indeed a spinning ball. Unfortunately, he will not accept any information provided by Nasa nor from any other space agencies, as he is convinced they are all in on the Grand Ruse! So, I decided to do a test of my own here where I live.
I have seen the island of Ibiza off the coast on a number of occasions, and had been waiting for a clear day to take some photographs and perform some calculations (with the help of metabunk's Earth Curve Calculator.)
As I understand it, at a 90km distance from the mainland, a noticeable portion of the bottom of the island should be missing due to curvature, approximately 133 meters, in accordance with spherical mathematics, and accounting for standard refraction.
The day finally arrived and I took a number of shots at an initial altitude of 140 meters. The island was clearly in view, and landmarks made it possible, with the help of Google Earth to calculate altitude of different parts of the island.
The peak on the far right of the island has an altitude of 415 meters. The lowest point of the saddle to its immediate left appears to be approximately 210 meters in height.
At 210 meters altitude, minus 133m allowing for curvature/refraction, only 77 meters of the saddle should be visible. It was hard to determine whether this was the case, so I later descended to an altitude of 85 meters and took another picture of the island.
This change in altitude means that approximately 200 meters of the island should be hidden from view! The highest point of the saddle is at best 210 meters, yet in the pictures, far more (is not all) is seen. In fact, based on the height of the peak to the right, it appears the entire island is in view, though some of the island is clearly obscured behind a white band of atmosphere just above water level.
In the picture below, the white band appears to have thickened. This I imagined was due to my lower vantage point (85m), and thicker atmosphere.
While trying to come to terms with these numbers, and the apparent lack of curvature, I happened to notice that in a number of my photographs I had also captured an additional island to the left of Ibiza. Imagine my shock when I realized that it could be none other than Mallorca!
The distance to the nearest point of Mallorca from where I was standing was 202 km!
When I ran the numbers through the Metabunk curve calculator, my jaw dropped. At at an initial altitude of 140 m and a distance of 202km, at least 1644m of the island should be hidden from view! This is hard to come to terms with give that the highest point on Mallorca is Puig Major, clocking in at 1364m altitude.
This means that the HIGHEST point on the island should be COMPLETELY hidden behind approximately 300 meters of curvature. How can this be? Not only is the island not completely hidden, but a fair portion of the rest of the island can be seen!
As I examined the photographs more closely I discovered that to the right of the darker portion of the Island of Mallorca could be seen sections of the island that are at least an additional 30km further away. This distance brings the 'refracted hidden' number to 2336m, nearly a kilometer lower that the highest peak on the island!! Please explain to me how this can be?!?!
While I was not able to see these portions to the right of the island of Mallorca from the lower vantage point of 85 meters, the darker section of the island was still clearly visible (1863 refracted hidden).
These numbers do not even take into account the rather large section of the island (vertically) that can be seen in all the photos.
Help!
Kind regards,
Mike
