At 45,000 feet one can see the curvature of the horizon.
Looking curved and being curved are two totally different things.
If I was going to form beliefs based entirely on my visual cortex's limited ability to interpret clouds of electrons then, when looking in this mirror I would honestly believe my legs were suddenly grossly deformed and rush to the hospital
Just because the girl's legs look long and deformed does not make them long and deformed.
At 45,000 feet at night, one can see cities hundreds of miles away. Can you see cities hundreds of miles away from the ground?
NO. The FE explanation that is most plausible is that at sea level the atmosphere is much more dense than at 45,000 feet above sea level.
In the thinner, much less dense high altitude atmosphere, light is less hindered by refraction and other chaotic atmospheric conditions and can travel further.
This is why when you go just a few hundred yards below the water you can no longer see any sunlight. Light can't travel as far in water. If I was going to make my mind up based entirely on what I see I would say the sun stops existing once you go deep enough in the water then comes back when you surface.
False. I have seen Oklahoma City from 40,000 feet above Omaha. That's about 400 miles. 40,000 feet is about 8 miles. So a triangle with a height of 8 miles and a base of 400 miles will describe an angle of a little over 1 degree. using a little trig, from my vantage point, the last 50 miles to OKC is through air that is 5,000 feet and below. Denver is at 5,000 feet. Standing on the ground at Denver looking east, one cannot see a light source 50 miles away. Air clarity has very little to do with this.
Do you have any evidence to back up this claim that atmospheric conditions have very little to do with that?
What if it's foggy? What if it's misting? What if the pollen count is much higher than normal? Based on my own personal observations things like that have a very significant impact on what you can, and can't see. I'm not even considering things like atmospheric pressure, humidity, temperature, wind speed etc.
Let me present you with some evidence:
1:32 PM at 64.7 degrees the opposite shore is visible.
1:41 PM at 64.9 degrees the opposite shore has set behind the horizon again.
Same day, same time, same place, same cloud cover, same weather, same wind, almost the exact same temperature and an entire town goes from being visible to not being visible.
Based on the logic of things being visible meaning the earth is round and forming an opinion based entirely on your brain's ability to form an image out of a cloud of electrons: do you believe, based on the evidence above that the earth alternates between being round and flat?
