This Flat Earth Deception post shows that we can use the Earth Curve Formula to mimic a planet so large that it is essentially flat on top, to prove that the Earth is not flat.
Here is the Earth’s Curve Horizon, Bulge, Drop, and Hidden Calculator, which people use to try to prove that the earth isn’t curved.
This is the default setting of the globe earth with a radius of 3,959 miles, which shows that if your view height is 6 feet, then your horizon line is 3 miles away. And that’s pretty much what we see in real life.
Most photos from flat earthers are taken from an elevated position, which extends the horizon line; so just plug the estimated height of the elevated position into the Metabunk Earth’s Curve Formula, and you will see that the horizon line matches up; proving the curved Earth.
In the below calculation I used the Advanced option to add 7 zeroes after the planet radius, to mimic a planet that is so big that the flat top is bigger than the supposed flat earth.
And it shows that if your view height is 6 feet, your horizon line is 9,482 miles away.
Now of course your eyes can’t see that far, but a good telescope would be able to see across the flat plain to be able to see that far.
The point is that if the earth really were flat, then you would be able to see much, much further than 3 miles.
Californians should be able to see Hawaii with a telescope, or Mt. McKinley, which is 20,000 feet high. From atop of Pike Peaks, which is 14,000 feet high, I should be able to use a powerful telescope to see all of America.
But the reason that we can only see to the horizon line is because the earth is curved.
