##### Revised: concave and convex spotlight
« on: January 17, 2012, 09:41:02 PM »
when high altitude photographs are taken and people point out that they can see the curve of the planet the general response is that what the observer sees is the area where the suns light reaches and we are infact looking at the illuminated area of the earth. beyond the light are just parts of the earth that are not visible because that is where it is night.

figure 1. high altitude photo taken in the day

as we can see here the illuminated area has an edge that is convex in shape as expected. this is because the light from the sun works like it does in figure 2.

figure 2. artists impression of the light shining on a flat earth

that is where the term spotlight sun comes from. it is not to be taken litterally but its just the term used to explain that the sun illuminates a round area just like a spotlight does.

figure 3. dawn photo taken from a high altitude

however in figure 3 we now see the light from another angle and now it looks as if the shadow is convex and the 'spotlight' is concave in shape.
as sunrises and sunsets happen simultaneously we must concluse that the spotlight effect is both concave and convex at the same time depending where the observer is.
we also observer the same thing on the moon and possibly other celestial bodies, but i have not witnessed these myself.
the experiment can be repeated using a sphere of any size using a direct light source pointing and one half of the sphere. when the observer walks arround the sphere they can observe that the light observed from directly behind it casts a convex shape, but if the observer walks round and observes the area where the sphere is mostly in shadow and only a thin area of light is allowed to be seen they will observe that the shadow is now convex and the light has become concave on its outer edge. this is roughly drawn in figure 3.

figure 3. artists impression of simulated day and sunrise as observed from a high altitude.

the real life images used are from a satellite or as some will say a NASA high altitude plane disguised as a satellite. either was the same pictures can be seen from weather balloons. these pictures are chosen as they show what im trying to discribe quite clearly and high altitude aircraft or weather balloons tend to still have haze distorting the far edge of the visible earth because of the atmosphere.
i have yet to come up with any conclusions as of yet but so far the only time i have been able to reproduce the phenomenon is when i have used a sphere are a test model.
another way to check the results would be to launch my own balloon and not the area that is furthest from view. then check the times beyond that and calculate where the light terminator actually is. but i do not have the means unfortunately.

You're too kind. You made your point well enough the first time. You've made a clear case for the FEers to answer. Good job!

I've always challenged the FEers to tell us how the curve appears at the RET-predicted location and angle while FET just mumbles. Your attack here is better and well presented.

Any Zetetic will tell you the sun is not a spotlight.
Please ignore this in the FAQ, i dont know who wrote it,
but they were not using the Zetetic Method,
also ignore anything to do with a massive conspiracy, also not Zetetic.

Thank you for your post, if we get enough outcry, the powers that be here will remove it.

You clearly didn't read the post:

that is where the term spotlight sun comes from. it is not to be taken litterally but its just the term used to explain that the sun illuminates a round area just like a spotlight does.

The OP never contradicted your assertion that the sun is a sphere rather than a literal spotlight.

Do you deny the assertion that the sun only illuminates round areas? Yes or no.

so no opinions at all. i was eagerly awaiting the usual comments but i havnt even had one of those. isnt this proof of bendy light atleast? would seem the only real explanation if the light was shining on a disc. dam now im even debating with myself. what a looser... : /

firstly reguardless of what others have said this is not an attack on anything. i wanted to discuss what is observable and how this is applied to FET. perhaps PP you will be willing to provide some of your own thoughts on the subject? do you really think it is caused due to bendy light or refraction? can you perform an experiment for this? i was also thinking of thorks whirlpool theory too.

"You seem to already know the answer. Why bother the others?"

isnt this an area for debate? also what does your statement imply? what is the answer that i already know? i think i may have the answer as this experiment can be duplicated using a sphere very easily. but i thought my findings were thought provoking atleast.

i believe the lack of witty remarks from the fes may imply that there isnt an answer to concave and convex spotlights, thats fine. worth some serious disscusion though dont you think?

do you think figure 3 could be an effect similar to this?

if you look at the image for a few moments you will see what i mean. the 'spotlight' is at a great distance so it would look very thin. would it not?

edit* i didnt explain that very well. what i mean is figure 3 almost looks like its curve bends both ways perhaps?

Personally, I support the belief that the area illuminated by the sun is many times the size of the Earth, kind of like this:

This is absolutely not to scale. Just an illustration of the concept. With the right scaling, the lit area is quite similar to just half the Earth, and the dark area on the Earth is concave. That seems to be consistent with most pictures I've seen. It makes for some inconsistency with RET, but RET should not be assumed as default.

As you said, it is likely a proof of bendy light. Sorry if I seemed aggressive, it just looked like you're trying to bait people into something here.

It could be a nice topic, but the discussion should probably be more specific. I would imagine you're getting no answers because it's hard to tell what exactly you're asking. You seem to be saying that the apparent shape of the Sun would have to do with how it illuminates the Earth, but I see no reason why you'd say that.

Please do tell us what pictures your model is consistent with. For example, do you have any pictures taken in the Arctic Circle in December?
Do you agree that the U. N. Logo map of Rowbotham is approximately correct.
If so, can you explain how the area of the Earth inside the Antarctic Circle receives little or no illumination in June?
If not, please provide the map you use to test your 'belief'. Thanks.

I'm sorry, but I can't do it, because I haven't taken your remedial course in using the search function yet. You, however, seem to be quite proficient in the technique. An exercise for the reader.

For example, do you have any pictures taken in the Arctic Circle in December?
I don't personally have any, but with this model I would imagine the Arctic circle to be mostly, if not completely, illuminated. I've never been there, though.

Do you agree that the U. N. Logo map of Rowbotham is approximately correct.
Approximately. I prefer a Polar Lambert projection, though. I'll find a picture in a moment.

EDIT: Here you go:

Of course. Orbits are elliptical, not circular. However, this is part of the reason why I support NASA's little Polar Lambert map, rather than Rowbotham's.

I see. You don't have any evidence. I think we're done with your model then. Please do stop back when you have done any science.

@PP no i wasnt baiting at all. its pointless anyway, happens constantly. the post is all about the spotlight shining both a concave AND convex shape on the earth. but this depends where the observer is standing. it was just something i couldnt comprehend in FET and it was something worth talking about. it has nothing to do with orbits really either. we all know that from the earth we see the sun go round it. the the lit area and the shadows that im concerned with

No you don't. Stop being so misleading. Every time you post your map, you should include a huge disclaimer stating that you do not support the idea that Earth is a disc, approximate or otherwise. You use the same distance transformations as do the creators of the Lambert projection, and you use magic to explain why the distances can be the same as on a globe yet still map to a physically flat plane.

Unfortunately PizzaPlanet's the only one who has attempted to respond to your OP, so this is the only track available to this train right now. It's not necessarily going anywhere promising, but it's not derailed.

The map argument isn't unrelated to the thread at all. You see, PP's claims about what is the true physical shape of the Earth are critical to his response to this thread because it makes a huge difference when you realize that the circle representing Earth's surface in his sunlight diagram is actually what he claims to be an optical illusion and not a physical object upon which light can shine. Not to mention the whole concept is completely incompatible with the bizarro bendy sun theory he uses to explain the disc-Earth optical illusion in the first place.

In the middle of the lit area, wherever that would be.

Also, zerg is getting it backwards - he thinks the Earth is a sphere that looks like a disk, when it's more or less the exact opposite. He also thinks my magic (which is elementary optics, merely with the inclusion of bendy light) is "worse" than his magic (universal gravitation, a magical theoretical force that for some reason is taught as if it were proven). Let's just stick to the topic and hope he trolls elsewhere.

Gravity is readily visible.  We may not have an explanation for why mass distorts the universe around it, but we know that it does.  Gravity is not theoretical, its just not fully understood.  But we use it to fly our space ships,  we use it to make accurate predictions for many things.  Gravity as a theory works well, in fact its never been proven false.  We just keep changing our theory of how it does what it does.

I thought that even the FE theorists, (certainly Rowbotham) accepted that the Sun is always in the zenith of some place on Earth. In fact, all ideas of bendy light until now accept that when sunlight comes from the zenith it comes vertically down, without bending.

In this diagram it is perfectly clear that the Sun will appear to be very close or (if you believe in bendy light) under the horizon for everyone on Earth. But I can tell you, since I live close to the Equator, that the Sun passes close to the zenith at noon every day. Every day that I look it is up there, and any day that the Sun were close to the horizon at noon the long shadows would be quite evident.

As always, every new "theory" from these people creates more problems than it solves, and in cases like this one it does not even solve anything.

Which means that it's not above the equator where it is observed every equinox, correct?

No.  The effects of gravity are readily visible.  Gravity itself is quite elusive.

No, you don't claim Earth is a disk, you claim it looks like one. Explain how Earth can be physically shaped like a disk if S1 and S2 are equal lengths. You can't. It's geometrically impossible. Instead, you say that Earth is a magical shape that somehow manages to be two dimensional. You refuse to draw that shape.
