This would be true if the earth had no atmosphere. In reality due to atmospheric refraction, more of the ship would be visable to the observer in the lighthouse. How much light would be refracted would depend on air temperature, pressure and humidity.
So you see, light refraction allows us to see further round the earth than the maths says we can, NOT because the earth is flat.
That's so funny. Yeah I've heard of it before. Just goes along with all the assumptions people believe thanks to scientists. To believe in the sphere Earth you really have to believe a lot of assumptions based on scientists' studies.
And this is a "mirage"
Mirage of Chicago skyline seen from Michigan shoreline
Yes, correct this is a type of mirage. Because light waves are bent around the earth due refraction.
If the Earth was flat, light rays that bend down would soon hit the ground and only nearby objects would be affected making these types of mirages impossible.
I see you are finally coming round to understanding the Earth is round.
Not so much. The most reasonable explanation looking at the Chicago skyline from the Michigan Shoreline would be to believe you're actually seeing Chicago because the Earth is flat. Remember Occam's Razor? "among competing hypotheses that predict equally well, the one with the fewest assumptions should be selected."
A person who believes in the flat Earth and sees a city skyline from 60 miles away, doesn't have to explain anything.
A person who believes in the globe Earth and sees a city skyline from 60 miles away, they have to explain....
The flat Earh person has to explain MUCH more than the global Earth person because they are assuming every scientific experiment that has every taken place and been proved is wrong, because of the domino effect.
You see that's the very problem flat people have, and why their position is impossible to stand by.
They cannot explain flat earth without sweeping other scientfic proofs out the window, which in turn sweeps other scientfic proofs out the window, which in turn sweeps ............................., in the end they are questioning how we think atoms work. Hundreds of thousands of experiments over thousands of years rejected and thrown in the bin. Good luck with that.
