Title: Garlic bread and the curve of the earth.
Post by: nickrulercreator on May 01, 2018, 02:11:33 AM
Tom Scott, famous youtube scientist person, recently uploaded this video onto youtube: https://www.youtube.com/watch?v=c8W-auqg024, where he released garlic bread on a high-altitude balloon, strapped a non-fisheye lens to it, and sent it off into the upper atmosphere. While it did NOT reach space as it's so claimed in the title (Tom even acknowledges this in the beginning of the video), it did get WAY up there, about 35.8km when the balloon pops. In the video, numerous clips were shown where the earth's horizon was curved! When the horizon was in the bottom of the frame, the horizon still curved downward, not upward as it should if the lens was fisheye. Here's screenshots with the timestamps included: https://imgur.com/a/dzJq2MH (this one shows the curve just before the balloon popped at 35.8km). https://imgur.com/a/Xk0z04O (this one shows the curve just after the balloon popped at 35.5km).

Notice how neither photo has the horizon filling up more than half the frame, and yet the horizon still curves away from the middle, rather than toward it if it was fisheye?

Now, I know some of you will say "oh well where is the full unedited video. Why didn't he upload that? It MUST be fake then."

Well, here you go then: https://www.youtube.com/watch?v=YKAblynZYhI

And for MUCH of the time you can see curve. Not fisheye. Not some act of perspective. Real, authentic, curvature of the earth.

The "curve" most everyone seems to want to look for to distinguish a globe from a flat earth is (I believe) a false quest. Here's why:

When looking from high above either a sphere or a disc, the "horizon" of either transcribes the base of a cone. If the viewpoint is the apex, the angle from horizontal in all directions is a 2D circle, either the circumference of a sphere (or spherical cap) or circumference of a disc (or some smaller circle on that disc).

From the surface of the base, the lateral line is "flat" but it surrounds you in all directions. It "curves" toward you radially as you turn 360°. As you increase height over the base, it'll keep doing that, but you'll start to see the "curve" of that arc of the circle. It's not the "dip" of the horizon left or right because the angle looking down doesn't change. 

(http://oi63.tinypic.com/2rh5uvc.jpg)

Even when you can see the whole of a flat disc or whole of a globe, you still don't know which is a disc and which is a sphere, unless you can determine relief in the z-axis (the same axis as height) or you can gain an oblique angle, in which case the 3D disc will reveal itself while the sphere will be retain symmetry.

The "curve" that matters in distinguishing sphere from flat isn't along the transverse of a horizon. It's the "dip" toward and away from the viewer, not left/right.

The right honorable Samuel Rowbotham didn't understand this either when he incorrectly presumed this should be an attribute of a rotund earth in Experiment 7 of "Earth not a Globe"

(http://www.sacred-texts.com/earth/za/img/fig18.jpg)

Likewise, globe defenders claiming to see the horizon curve from high altitude aren't actually resolving the dispute either. The horizon being straight (or not straight) across the horizontal is not a marker of globe/flat.

Is there anything wrong with that contrary argument?

You went out of your way to state many times that the lens wasn't a fish-eye. While this much is obvious (you're clearly responding to an argument about very different kinds of "space" photography, but I'm not very surprised that you'd try to conflate these to make your argument sound "stronger"), you can very clearly see the extent of curvature change within seconds as the camera pans up and down.

You can also see moments at any altitude that share the same extent of curvature - even comparing "just barely off the ground" to "high up in 'space'"!

Gee, oh gee, I wonder why that might be. Since it's clearly not optics, as you so strongly asserted with 0 evidence, it must be that the curvature of the Round Earth physically changes depending on how we look at it.

I get your point but from the cloud patterns it looks like they are wrapped around a globe. A flat painting can be made to look 3D using perspective in the way it's drawn so it's possible that this is a disc but it gives the appearance of a sphere.

The craft was seen by thousands leaving Cape Canaveral going East, two sets of these videos were seen of it passing over Australia in an easterly direction toward the Pacific, with perfect matching between what was seen from this craft and the weather satellite over the Australian region, and witnesses with cameras saw the exit burn, where it left Earth orbit, from the West coast of California.

In the same way that I saw the ISS crossing my sky with 90 minutes between passes; nobody saw this craft changing direction, nor going westward at any time. All footage is entirely consistent with a craft travelling Eastward to get back to where it started from.

All reasons other than (or complement to) the “curve,” because that curve is circumference arc - which both circle and sphere possess - and not horizon dip, which a sphere has but not a circle.

Would you mind providing a screenshot of this? Some evidence? Perhaps a timestamp even.

I'm not wrong. If the lens was a fisheye then the curve would be going toward from the center of the frame no matter what, but this doesn't happen.

This is 2D "curve", like the curve of a circle.

It's the 3D "curve" that we want to detect, and that is the "curve" way/toward the viewer in all azimuths. You can't see that curve in 2D. You need to infer it from other phenomenon or from multiple perspectives (stereoscopic) or other clues, like shadow, relief, etc.

The curve of a circle (such an an arc on the circumference of a spherical cap or that of a flat disc) is different and doesn't help distinguish between flat and sphere.

You are wrong. This effect will be present in any camera lens currently in existence - a wide angle lens will exaggerate that effect, not introduce it. Also, how did you establish where the centre of the lens is in this footage?

So it's impossible to take a picture/video of the flat earth because it will always look like a globe?

If that's the case what defining feature from a shot like this would prove a flat earth? I've yet to see any ice walls in experiments like this.

Yes, I know that ANY lens will, but what I'm saying is that he did not use a wide-angle lens. If he did, there'd be extreme exaggeration. His lens had a very, very small fisheye effect. This can be known by looking at the horizon at the beginning of the video. There is almost no curvature unless the horizon is at the extremes of the frame. At the point of the video where the balloon pops, theres curve no matter where the frame is.

I determined middle by connecting the corners. Draw a line from top left to bottom right, and the same from top right to bottom left, and the intersection is the middle.

Seems unreliable. It sounds like that would establish the centre of the image you're viewing, not of the area covered by the lens.

Wait, how does the garlic bread help the experiment design? It just seems like something you'd do to make the test more (pardon the pun) digestible and spreadable to the young "meme" culture. You're highlighting information that emphasizes an easy, wide-spread message over the rigors of the scientific method.

This isn't science, it's propaganda.

They would only differ if someone had cropped the image between shooting and display, surely?

Well, it's not unreliable because it find the middle of the video frame.

We'd have to know if Tom cropped the video to determine where the real center is, then. I'm doubting he cropped it though.

In other topic you have difficulty seeing curve, now you have no difficulty seeing curve. ??? For me actually other way around. Previously saw curve easily. Now I have difficulty seeing curve.

Anyway, so that we can look a bit closer here some stills from movie. So we can see and observe what we can gain from our knowledge. After all we need to be shown to accept something as truth, so what exactly are we shown here lens effects and all?

I think one way to debunk this would be doing the flight at sunrise/sunset. If you can fly a balloon right over the terminator line on Earth, you'd still see the curve on Earth on the side lit up, but that shouldn't be possible if the sun was a spotlight. If the sun was a spotlight, you'd see the circle of light curve away from you to the horizon on both sides (around the sun), you wouldn't see the actual horizon curve. I'll try to make an illustration later if I can. Not sure how to describe this any easier.

Finally drew it. Here's crude representations of what should be seen:

(https://i.imgur.com/fLZWPlD.jpg)

Above is a RE model. The top left illustration is a view (if facing North from directly above) of sunlight hitting Earth, with the arrows representing light. The shaded side is the night side, and the circle on the terminator line is the location of launch of the balloon (or rocket or whatever). The illustration along the bottom is what should be seen from a non-fish eye camera. The horizon, curved, is curved regardless of where the light is. It's curved all around. The terminator line is a straight line. It does not turn relative to the camera.

(https://i.imgur.com/BUGtnYx.jpg)

Above is a FE model. The top left illustration is a view (facing from directly above) of sunlight hitting Earth. The non-shaded area is the light coming from the spotlight sun, while the shaded area is night. The circle on the terminator line is the location of the launch of the balloon. The illustration along the bottom is what should be seen from a non-fish eye camera. The horizon would appear curved only where light is due to the circle curving around the sun, but the terminator would also appear to curve to the right or left, depending on your orientation (the terminator line would encircle the sun). This isn't seen, ever.

I apologize for the not-to-scale, crude representation of the models. I do not know how to do 3D modelling in software, so if someone could (using accurate scales), that would be infinitely helpful.

This is a great video, thank you. You can clearly see the terminator line is not curving around the sun, but with the curve of the earth and in a straight line.

I made this image for comparison of curvature.
(https://cdn.pbrd.co/images/Hi5AFA1.jpg)

Mostly this video just shows that there is curvature, we can see curvature, which goes against the core princible of flat earth 'the horizon doesn't curve'.

The only thing done to the images is changing the color levels to create lines in the gradient. This easily shows the transition and curve of the gradient (if any), and can easily be done in free image editing software, such as Paint.NET which is used here.

Of course the horizon curves. The horizon wraps around you in a large circle 360 degrees. If the horizon was dead straight you'd have to be able to see further away from you at 45 degrees than you would looking straight ahead and there would be no horizon behind you ... it would be parallel to you. Does the earth fall away at the edges? Your garlic bread doesn't convince me that it does. You want ball like curvature, not dish like curvature.

You sure are hostile...

On the ground at sea level, the amount of curvature we would see is not noticeable due to the size of the earth. The horizon would be basically flat, no matter which direction you are looking. This is one of the primary arguments of the flat earth that the horizon is always at eye-level and the horizon is flat (exactly as we see it when viewed at sea level). This observation holds true on both the flat and globe earth, yet when rising to extreme heights, we expect a drop in the horizon and a visible curvature on the horizon on a globe earth, which should not be there on a flat earth.

We can accurately predict and simulate the amount of curvature we would expect on a globe earth at any given altitude, and we can actively observe that the predictions adhere to reality.
Meanwhile, the flat earth can predict nothing, it is impossible to simulate, math doesn't work with it, you need to invent new methods for perspective and ignore common sense in regards to observations, you can't make a proper map, or even a concept model which can explain the stars clockwise rotation in the south without making a whole new model only used in this single case.

If you scale your imagery to the size of earth, you would be hundreds of kilometers above the earth. If however you were straight above the surface on the gigantic earth, you would see a flat line.
Besides, in both your examples, you are looking down towards the horizon, which also indicates that the horizon is not eye-level in your examples, also a clear violation of the FE 'the horizon is always at eye-level'.

The idea of this topic is to disprove one of the primary beliefs in the FE, that the horizon is always flat.
Since you already seem to believe that the horizon should curve due to geometry, this topic isn't meant to persuade you.

Why would you expect to see further to your left or right than you can straight ahead?

(http://i65.tinypic.com/2hd1lrc.jpg)

The horizon has to curve if you can always see the same distance in every direction. This is pretty basic geometry. There is no 'basically flat'.

False.

You are trying to apply a top-down view to show perspective.
Just like your previous images showed a very high position of the camera/eye, this will of course not show a flat line when looking down on it.

Real life demonstration example:
If you have a hoola-hoop, hold it horizontally, and place your eye inside the hoop at the same level as the hoop, you will see a completely flat line.
If you move your sight further up, then of course you will see curve, but if you compare your altitude to the hoops, and scale that to the giant earth, you will see how far up we need to be to properly see curvature.
Comparing our height above the earth, to the height you would be over the hoola hoop, would probably be 1 millimeter up, resulting in seeing a 'basically flat' line from the hoola hoop.

This is basic geometry and perspective. Easily calculated, simulated and observed.

I can easily show this too you with 3D models, but I do not have time for that today.

Or take a picture of Thork's plate, but as a fly would see it. Looks dead straight.

This isn't the same. Numerous independent observers have done the same thing and seen similar results (curve). Why should this, or any, be fake?

I'll make it simpler.

Imagine the earth was a flat square ... what shape is the horizon?

Something like this? With a straight horizon?

Now imagine it is a flat disc. Still got a perfectly straight horizon?

Nope.

Only a lunatic would say "the horizon bends and therefore the earth must be a ball".

Here is me looking out over the edge of a dinner plate.

Its not a ball, is it? But it has a horizon, a curved one.

This is only true if you do this near the center of the spotlight from the sun. Otherwise the curve around you will appear much different depending on where you look. It won't appear as an equal, continuous curve as should be seen on a spherical Earth (and as seen in reality).

I agree with the flat disc principle, but you lost me there. Are you saying that in the garlic video we are looking at the edge of the earth? The curvature is the shape of the flat disc, the end of earth?

I never thought of it that way. Perhaps we should get a large telescope up there on a balloon. My wish is to see pictures of the ice wall once in a lifetime.

No, it isn't the edge of the earth, it is the edge of your perception.

If the first 50 miles is 2 inches vertical, and the next 50 miles is one inch vertical ... eventually 50 miles is a millimetre, then a nanometer to the point you can't tell how far you are seeing. It all merges into one and forms a curve around you with you at the centre.

I'm not wrong. If the lens was a fisheye then the curve would be going toward from the center of the frame no matter what, but this doesn't happen.
You are wrong. This effect will be present in any camera lens currently in existence - a wide angle lens will exaggerate that effect, not introduce it. Also, how did you establish where the centre of the lens is in this footage?

Almost correct, any lens  (and excuse my terminology, its been years) that magnifies the image does the opposite, the lines curve inward.

Did they perhaps use one of these?  https://en.wikipedia.org/wiki/Rectilinear_lens

So as said elsewhere, we simply leave the subject unknown. Could be a ball could be a flat disc, we just don't know as we cannot perceive the difference.

Is that what you mean?

But still, I think if it is flat disc as would not surprise me, we should be able to see the edge of it with a large telescope, no?

No, but that is a discussion about meteorological visibility and not vanishing points.
