It isn't my video. I am simply showing your argument is the wrong way to go. You can see light houses 200 miles out at see. This dismantles the point you are making. You can also see a ship on the ocean go over the horizon looking like it has disappeared by the curvature UNTIL you use a telescope and the whole ship comes right back into view.
I know that. What I meant by “your video” is that you posted the video link and then claimed it addressed my point—that you cannot see New York with a telescope from 200–300 miles out in the ocean on a clear day. I then provided the transcript, and you still have not explained how that claim was actually covered in the video.
Now you’re claiming that lighthouses are visible from 200 miles out at sea. There are no lighthouses that are directly visible from that distance. At most, light may reflect off high-altitude clouds that are tens of thousands of feet above the ground, but the physical lighthouse structure itself would not be visible.
According to the USA's National Geospatial-Intelligence Agency, which maintains a global archive of navigational beacons (i.e., the "List of Lights, Radio Aids and Fog Signals"), the lighthouses installed with the brightest lights active as of Sep 2022 are two sites in Brazil: both the Abrolhos Lighthouse on Ilha de Santa Bárbara, the largest island in the Abrolhos archipelago off Bahia, and the Ilha Rasa Lighthouse, south of Rio de Janeiro, have flashing white lights rated with a nominal range of 51 nautical miles (94.5 km; 58.7 mi). Both lighthouses are maintained by the Brazilian Navy.https://www.guinnessworldrecords.com/world-records/69033-greatest-ranged-lighthouseIt's worth noting that "nominal range" relates to the maximum possible range for a light on a clear day and does not take into account prevailing weather conditions which might impact visibility (the "luminous range") or the curvature of the Earth/position of the observer (the "geographic range").Now you’ve made me extract frames from the video I posted in DaVinci. Thanks for the extra work. Notice how the cabin of the sailboat disappears below the horizon due to the Earth’s curvature.
