A Question About Horizon
« on: March 19, 2020, 01:28:32 AM »
So, this is a question I haven't seen brought up on this forum. Pilots of high-altitude airplanes can approximately tell which altitude they are at by flying horizontally and looking at the angle at which they see the horizon.


In that formula, 'r' is the radius of the Earth, around 6'000'000 meters, and 'h' is the elevation you are at in meters.
So, if you are at the Mount Everest, 9'000 meters above the sea level, the angle at which you see the horizon is 3.14 degrees, but that's probably not perceptible there because mountains hide the horizon. However, if you are at 30'000 meters, where some airplanes fly, it's 5.7 degrees, and that's perceptible. But how is that possible if the Earth is flat?

When i looked out the side window of a plane i remeber seeing things fade awway without a clear horizon. Some people say you can see the curvsature from the cockpit, nasa disagrees w/ seeing curvature from that height, as you probably know.

I am not talking about curvature. I am talking about the angle at which you see the horizon. At or near the sea level, it's 0 degrees, the horizon is at your eye level. When you are in an airplane, the horizon is visibly below you, it's not at your eye level, even though you don't see the curvature. I've been on an airplane and seen that.
You also see sunset later than people on the ground do, though I haven't done that experiment.

The horizon is always below my eye level. I've never experienced otherwise. Unless my "horizon" is a mountain range or some kind of hilly, blocked terrain.
I saw a slight haze in the hotel bathroom this morning after I took a shower, have I discovered a new planet?
