    Sorry Freaky, this nails it even for you.

    I shouldn't have to point it out, but.

    According to your go-to-but-never-works-because-you-don't-know-how-it-works-or-applies, i.e., light refraction.
    Does it only work on ambient light?
    Or does it work on laser scatter, too?
    Is that light scattering up--- due to refraction caused by atmospheric conditions?

    Also...
    Why so many moving parts?
    Why so many extra points of transference?
    Simple--- super simple--- three objects between two points over flat water:

    Eye
    Camera/Telescope
    Distant (20-30+ miles) Object

    No fluctuating elevation.
    Reliance on single mechanical device.
    Basic Pythagorean math.
    Easy peasy.

    No, not with, as you said above, "scattering". And that would make no sense for a lazer beam anyway.
    Particles that scatter light (such as fog particles) wouldn't just scatter light 'up' but sideways and down thus a scattering effect would mean the lazer beam would not be seen to stay narrow, as it did in that film, but spread out in many directions and blur over a very wide area. The same is true for Rayleigh scattering from air molecules.
    The only simple and reasonable explanation for what was observed in that film is that the water surface is curved and that clearly indicates curvature of the Earth.

    Spherical right? Not round. This isn't exactly a novel finding, the ancient greeks figured this out using a stick.

    I know, I was baiting Freaky. He is a card carrying flatearther. I also knew he would be putting forth the argument that somehow the laser would shoot upwards.
    Which is funny, how the laser would shoot upwards but the boat, not so much🙂

    Ah, you mean you now know why you see those buildings across the lake?

    So what is happening optically when light bends?
