Earth from space in YouTube videos

There are a lot of YouTube videos showing the earth from space, thanks to a weather balloon or something similar, now how you, flat-earth believers explain this? NASA conspiracy? Here's one: #ws" class="bbc_link" target="_blank" rel="noopener noreferrer">Toy Robot in Space! - HD balloon flight to 95,000ft You can clearly see the earth curvature. So that's a lens effect? or maybe that theory you are developing about the light curving upwards?...

You're looking at the spot of light the Sun shines upon the Earth's disc.

Then I think that illusion of inward curvature should not appear when the camera is shaking, right?

Then I think that illusion of inward curvature should not appear when the camera is shaking, right?

What makes you think that? The curvature is not an illusion. There is a difference between RE and FE curvature. RE curvature is due to the land mass itself being round in shape. FE curvature is caused by the viewing of a lit circle. Take a flash light and shine it on a wall. The flash light makes a circle of light on the wall. You're looking at a portion of that circle in the posted video.

I always thought that's because the reflector shape, in flashlights it's generally circular, but with a square shaped one it should be a square, like the monitor, the form of the light projected by it is a square.

In the flat earth model:
- the Sun is a sphere
- the Sun acts like a spot light

However, look at your light bulb at home, the light scattered in all directions. Are you suggesting some other mechanism for the Sun to give light?

Okay, I'm not sure why you thought any of that was relevant.

In the flat earth model:

Depends on the model.

- the Sun acts like a spot light

Pretty much.

However, look at your light bulb at home, the light scattered in all directions. Are you suggesting some other mechanism for the Sun to give light?

Are you suggesting a single street light (the Sun) can light an entire city (the Earth)?

Given that the earth is a plane, and the sun acts like a spotlight, then why in some places is night and in others day, you may say "Because the spotlight is not big enough to cover all the flat earth" then it should follow a circle shape, not one like this: http://www.daylightmap.com/index.php that can be got using the Mercator projection as the light comes hits bowl shaped like in this image: http://sos.noaa.gov/ftp_mirror/land/day_night/full_year/media/thumbnail_big.jpg(Big image). It's very interesting that people believe in a flat earth and I respect your toughs as some people believe in god and some people does not, I'm asking this questions to understand how you explain this phenomena with a flat earth.

Of course the day-night terminator is going to look fairly linear when you're looking at a Mercator projection, but it is well known that Mercator is not an accurate map. For example, Greenland is definitely not half the size of the continental U.S., but it looks that way on the map. The NASA image is a computer generated image and nothing more. It is not real nor does it represent reality in any way, shape, or form.

I could have sworn there was a picture showing the terminator on a flat Earth in the wiki, I'll have to look around.

Which model of the Sun is the correct model for flat earth?

If the Sun is a sphere, it will not act like a spot light that gives you a clear line of day and night.

You can try to experiment it with a small light bulb in a dark room. Although the light fade out as the distance increased. There will not be a clear line between the light and the dark.

A spot light, or an enclosed street light as you mentioned can gives you the effect of a clear light/dark line. However, in that case, the light source is no longer a sphere that gives light in all direction.

Therefore, you can't have the Sun as a sphere and the Sun acts as a spot light at the same time. Unless you are telling me someone covers the Sun with a lampshade.

0:23-- Horizon is concave when viewed from the ground.
0:32-- Horizon incredibly convex. From near zero altitude.
0:35-- Horizon again concave after recovering from extreme convexity 3 seconds earlier.
...
...
2:54-- Horizon concave from extreme altitude.
3:00-- Horizon again convex.

Which of these am I supposed to believe represents the actual view of the horizon 

Ski is correct. A lot of these people who send high altitude balloons to the edge of space are using a wide-angle or fish-eye lens on their camera to get a wider view of the scene to keep the horizon in the frame as the camera shakes around. This results in false curvature.

So in the hundreds of videos showing earths curvature, they are all using fish eye lens... without a flat earth standardized model, there are a lot of inconsistencies, while there is a standardized round earth model. You guys need to standardize it if you want to convert non believers into believers.

They generally seem to use fish-eye lenses to provide a spectacular field of vision. And the effect is quite lovely. On the rare occasions that a standard lens is used curvature is either non-existent or nominal: certainly not indicative of a sphere.

So in the hundreds of videos showing earths curvature, they are all using fish eye lens...

Not all of them, but the ones that people post on this website are, since they are deliberately selecting the videos on Youtube with the most curvature.

I'm looking forward for a response to the above.

The sun is a spotlight in the sense that its light is limited to a circular area upon the earth. But this does not imply that the sun is a flat disk or only shines light in one direction. The sun is a sphere. It shines light in all directions around it. It's just that light cannot travel for tens of thousands of miles across the surface of the earth without being impeded by the thickness of the atmosphere. The sun is also very close to the earth. Natural perspective limits its visibility across great distances.

If this is the case the Atmosphere would have mysterious magical properties - it seems to completely block the sun's angular beams when viewed from the surface of the earth-plane, as well as be completely non reflective outside a defined ring when viewed from above.   

Its almost as if it does not follow any pre-defined laws of nature, but rather a life force that consumed photons for sustinance - or reality conforming to the whims of a Diety.

You are not answering the following:

You can try to experiment it with a small light bulb in a dark room. Although the light fade out as the distance increased. There will NOT be a clear line between the light and the dark.

But the youtube videos always show a clear line of light and dark.

A spot light, or an enclosed street light as you mentioned can gives you the effect of a clear light/dark line. However, in that case, the light source is no longer a sphere that gives light in all direction.

Perhaps you can demostrate some experiment that illustrate a clear light/dark line without using a lampshade?
