    I'm damned impressed with Birunis 1% margin of error. Hard to believe, since it it would require a precision to a hundredth of a degree in the measurement. But maybe.

    The problem with asking people to go up on a mountain to measure the angle of the horizon is that tall enough mountains are rather inaccessible to most people, and anyway we don't have astrolabes at hand. I propose the following equivalent experiment, to be carried out in an airplane with simple and cheap tools from the hardware store.


    --------

    Experiment:

    Measure the radius of the earth from a regular passenger air plane.


    Required materials:

    Air plane
    Tape measure
    Level
    Social skills
    An assistant (optional)

    [​IMG]

    Procedure:

    Acquire a window seat. In the diagram, your seat is on the left.

    Film (or look at) the horizon out of the window at the opposite side of the plane.

    Measure the horizontal distance from the camera to the opposite window. This is the length a in the diagram. Use your social skills to make the other passengers not get annoyed with you.

    When the horizon coincides with the bottom edge of the window, measure the vertical distance of the camera lens (or eye) from the level of the window edge. This is the length c in the diagram.

    Use your level to make sure the plane was level while you did this.

    Use your social skills to get an altitude reading from the pilot.


    The radius of the Earth is 2 * altitude * a^2 / c^2

    If c = 0, then the earth is flat, and the "radius" is infinite. If c>0, the earth is not flat.

    c > 0

    The spinning looks uncomfortable.

    That's not evidence, fool. There's no measurement. We don't know at what height the camera is mounted, and to which degree the plane is level.

    That's not evidence. There's no measurement. The apparent curvature is mostly caused by the camera lense. Note that in the end of the video, at ground level, he points the camera straight up, and the sky looks like a small disc.

    I thought Aeoli was being rhetorical rather than factual, answering Doompony's obvious handwaving with something even more blatant and handwavy. Good times. :)

    You're a fool for not being able to see the obvious. The spherical earth is a bunch of crap. 120,000 feet up and the horizon still at eye level? Not possible on a sphere.

    You still believe in the Sun, right? Here's how the Sun would work under the Flat Earth model, and there are some mismatches between the model and observation. For starters, if the sun just circles overhead like a tetherball, the sunrise and sunset would be in different directions then they are. Its path in the sky would be different. Since the sun does not move as predicted in the Flat Earth model, something is wrong with the model. (It's probably because Earth Is A Time Cube, but that's beside the point right now.)

    I deserved that. Never heard of a fisheye lens before. I got overconfident in my perspective and it made me careless.

    Thanks for pointing this out, I was jumping around in the video and didn't notice that part somehow.

    Nope, I just done fucked up and now I gotta take my medicine.

    Compare to increasing water pressure as depth increases.

    Boneflour, I'm not interested in replying to you because all you're doing is copy and pasting other people's material and saying "explain this then." Why should I invest the time to try and convince someone who has no interest in the topic beyond trying to make out I'm stupid?

    What about diverging crepuscular rays huh, did you ever think of those? Oh wait; it's just that atmospheric refraction does it, just like it makes long distance proofs, it's magic and does everything.

    Rhetoric is not evidence. Careful measurement is evidence.

    What do you mean, eye level? If I look up, the ceiling is at eye level. If I look down, the floor is at eye level. If I look at the horizon, the horizon is at eye level.

    Also Moonpony:
    Man, that is a good question. Why are people engaging with Moonpony despite this constant insulting of their intelligence?

    We must have some real Nobilids that are dedicated to discussing ideas even in spite of multiple, repeated personal attacks.

    My position is that I have nothing invested in you... and it would be easy to treat you like a fucking joke based on your shitty behavior... but I went out of my way to (semi)seriously engage with the actual topic to give you an honest shot. And also it's damn good TV.

    You've responded by projecting your own behavior onto me, and saying the ideas I brought up aren't worth your time.

    *posts 3 hours of other people's Youtube explanations*
    *something like 60% of the entire thread is copy pasting sourced material*
    *has infinite time to reply to Mycroft*

    I dunno man. Maybe hold yourself to your own standards?

    That said, it's my actions that will define me in the eyes of others, not my personal narrative of things. Everyone can see what we're actually doing. It may even be easier for them, because other people aren't as invested in the stories we tell to ourselves. Everyone can look at our actions, and get an idea of what's really going on.

    You get what you give, you started out trying to bring me down and carried on that way, I don't see why you're complaining that I've treated you exactly as you invited.

    9 pages - Flat-earth holds more gravity than regular earth, hehe. He keeps pulling you all in.

    Well then.
    We all know aliens crashed in 1947 because they flew Over the earth where the gravity is instead of Under it where there is none.
    A classic noobilid mistake, what you want to do when you travel in space is to set your flying thingamajing to the right force-frequency, tune in to that gravity of where you want to go, imagine coordinates, and make sure your craft is able to block all other gravitational pulls, and you will simply be ferried to the moon for example, its quite simple actually. All you need is a simple knudge like a boat in a stream and off you go, no need for any thrusters really. Not underwater currents, not air currents, but gravity currents. Simple!

    You don't want to crash into the edges of all the flat flying objects out there.

    OK, the earth is not flat. I am convinced now. But what about the Caribbean? Jewish invention?

    "The Caribbean doesn't exist, no desperate buccaneeers sail it, no corvette ever chases them, no puffs of cannon-smoke ever roll across the waves. Pure invention..."
