^^^ Those videos do show a minimum horizon distance based on landmarks (Google Maps) and, the margin of error from using approximate camera height is too insignificant to effect the outcome. Refraction is also too insignificant to affect the outcome. We are left with one and only one conclusion, that the Earth is flat.
A gyroscope proven to react to a 15°/hr rotation can't detect any Earth rotation and this is proof we are not rotating.
The 1887 M&M experiment shows that the Earth has a velocity of ZERO! The 1939 D&P replication of the Sagnac experiment falsified relativity and the Earth's velocity remains at ZERO!
It can be proven that NASA has Masons hanging from wires and bouncing around zero-g airplanes. They landed a foil wrapped cardboard box on the Moon and took composite/airbrush photographs of Earth from the lunar surface of Los Vegas. They're a fucking propaganda agency that puts out WWE tier adult entertainment with free atmospheric refraction tables.
What are you trying to say? People use sight for all kinds of things, because sight shows us what is there. But when things seen aren't depicted in such a way that we can determine what is there, we don't know what is really there, even though we have some sort of idea of what might be there. Your video is a work of crude art, not verifiable science.
Your silly video shows what it shows... a jumble of artistic colorations, some clear, some not, of... well, anyone can go watch it. It doesn't express measurable distance to any points from any points in any way. If you want to believe what the added writing says, that's fine. But we can't tell from the video if the writer made a mistake or not. The video is completely useless for determining distances to the horizon, even if it wasn't edited.
If you think the video expresses something like horizon distances in a more-or-less scientific way, you really need to go back and learn what science is all about. And if, based on this scientific understanding methodology of yours, you think that you are able to determine what M&M and Sagnac show, you are really missing it... especially if you accept them but reject all the findings of other scientists, along with direct observations.
How in the world dense are you? The gravity of your situation is pushing/pulling you into the position of being real funny farm material. Come on out of your dream world into the light of reality... like you can tell from that video what the distance to the horizon is... not. How in the world silly can you get?
Btw, gyroscopes aren't sensitive enough to detect the slow turn of the earth. How do we know? Take a kid's string actuated gyroscope and set it off. Notice how it twists and turns on its pedestal as it loses speed. With relation to the slow turn of the earth, you might need something as sensitive as an atomic gyroscope, like an atomic clock can measure rate of change very accurately. Your gyroscope interjections are totally useless for detecting movement of the earth.
