Because the earth is an oblate spheroid. A globe. Easy answer.
If you feel that it isn't clear, feel free to help rewrite it to make a better distinction between the actual sun and the visible sun.
If you feel that it isn't clear, feel free to help rewrite it to make a better distinction between the actual sun and the visible sun.Sorry to be so late posting this, but maybe you could explain why there is any "distinction between the actual sun and the visible sun" other than some slight refraction when the sun appears on the horizon?

You posted what appears to be light projected onto the atmosphere. Please explain why the outer edges of the sun are dimmer than its center.Are you saying those are not pictures of the sun?
I do believe that is the sun. I am asking why the outer edges of the sun are significantly dimmer than the center of the sun like a projection on a movie screen.
The Sun's surface, the photosphere, has a temperature of around 6000 degrees, but the outer atmosphere, the corona -- best seen from Earth during total solar eclipses -- is several hundred times hotter. How the corona is heated to millions of degrees is one of the most significant unsolved problems in astrophysics.
"Why the Sun's corona is so hot is a long-standing puzzle. It's as if a flame were coming out of an ice cube. It doesn't make any sense!"
Tom, how is that relevant to how sunsets work in FET?
The failure of science to explain what exactly? Science is about learning and working towards understanding what we don't yet know. Or is that irrelevant to you as well?

It is not irrelevant to me at all.
Science is working towards better understanding. I agree. We explain the inconsistent brightness better in our Wiki as being a cause of a projection upon the atmoplane, whereas RET cannot explain it.
If you want to challenge it, then we expect you to explain this under your Round Earth Theory.
I wouldn't say that "projection upon the atmoplane" is an explanation. As evidenced by?
I disagree. FET explanations need to stand on their own merit, regardless of any perceived failures of RET.Tom, how is that relevant to how sunsets work in FET?
The failure of science to explain this is entirely relevant.

Avoiding the topic is a submission of defeat. If you guys are unwilling or unable to explain or defend your RET, then I may as well be writing to myself.
What exactly is the topic we are to be defeated by?
You have not explained anything other than to declare it to be inconsistently bright. Why is the sun inconsistently bright? Why should the temperatures of the sun's corona, photosphere, and core be so different?
It does address it. Projections are inconsistently bright.1. LoveScience DID give you the RE explanation for it on the previous page. If you didn't understand it try reading it again, or ask for clarification.
You refuse to address this for your RET, while simultaneously claiming that your RET provides the better explanations. If it does, explain it.
Where did LoveScience solve one of the "most significant unsolved problems in astrophysics"? Please quote it for us.He explained why the sun is inconsistently bright, which is what you were asking. That's not the same thing as why the outer parts of the sun are hotter. If you wish to provide an FE explanation for why they're hotter feel free, but I suspect you don't actually think they're hotter under the FEH.
I don't see a quote where one of the "most significant unsolved problems in astrophysics" was solved. Please quote it.The mystery is "Why is the corona hotter than the center" not "Why is the sun inconsistently bright." I don't know how to put it more plainly. We know why the sun is inconsistently bright:
The inconsistent brightness of the sun is a mystery in Round Earth Theory. See the article posted on the previous page. If you are claiming that the Round Earth Theory provides the better explanations then I expect you guys to solve this mystery.
Tom, regarding your question...QuoteI do believe that is the sun. I am asking why the outer edges of the sun are significantly dimmer than the center of the sun like a projection on a movie screen.
The answer I have provided elsewhere but I will say it again. This is a well known phenomenon we see in 'white light' called limb darkening. The Suns 'surface' is actually a layer of its atmosphere known as the photosphere. Looking in the centre of the visible disk we are looking directly down into the lower levels of the photosphere where the plasma is hotter than in the upper levels. Hotter is always brighter on the Sun. At the edges we are looking more obliquely across the upper layers only where the plasma is cooler and hence darker. This gives the effect of limb darkening.
When observing the Sun at specific wavelengths such as Ha and CaK we are looking at light emissions coming from the chromosphere (sphere of colour) The chromosphere is above the photosphere and is normally invisible without special filters apart from during a total solar eclipse. If you look closely at photos showing totality you will notice the reddish prominences looking like flames arcing away from the solar limb. These are coming from the chromosphere.
The chromosphere, though much hotter than the photosphere is emitting light only at specific wavelengths and therefore the darkening effect is much less.
"Why the Sun's corona is so hot is a long-standing puzzle. It's as if a flame were coming out of an ice cube. It doesn't make any sense!" - David H BrookThey are NOT the same thing.
The explanation given by LoveScience is that the plasma is cooler there, and therefore darker. I have some doubts that a scientific journal or the field of Astrophysics will accept that explanation and consider this matter solved. Do you think that they would consider it solved based on that?

The NASA paper you cited is talked about the heat of the corona. We typically don't view the corona in an everyday sunset.
"The corona is usually hidden by the bright light of the Sun's surface. That makes it difficult to see without using special instruments. However, the corona can be seen during a total solar eclipse."
The corona is not relevant to the discussion.

I can say his explanation seems logical to me at least, but that's about it. Last I checked you weren't either of the aforementioned entities either, so from what knowledge do you claim to know what they would accept?

It's talking about the cool outer photosphere, and how odd it is that the corona is so much hotter. The outer photosphere is the dim areas we saw in the images of the sun. Directly relevant.
The core and corona of the sun is so much hotter. Why?
Tom, if the outer photosphere is the dim area in question, then why is the unseen corona relevant?The explanation given by LoveScience is that the plasma is cooler there, and therefore darker.

The corona can be seen every day with a coronagraph. It can be seen as easily as using a solar filter.But can the corona be seen during a sunset?
You have not explained why the photosphere is so very different than the corona and the core of the sun.This is the Flat Earth Theory forum and this thread is asking how sunsets work within FET. If you wan to know how the RE sun works, then I suggest you start a new thread in the appropriate forum.
Comments such as:Yes, in the same way that demanding RE explanations in a thread asking for an FET explanation is an admission that you can't explain your own theory.
"irrelvant"
"Doesn't matter"
"It's just cold, okay?"
... are all admissions that science cannot explain it's own theory. I expect you to keep this in mind the next time you try to assert some sort of superiority. Keep in mind that you can't explain your own theory.

The angle of the sun measured at different times of day and in different places proves a round earth, as you know. No theory, fact, nothing to defend.I disagree.

I am asking why the outer edges of the sun are significantly dimmer than the center of the sun like a projection on a movie screen.The duller "outer edge" in that photo is not the sun but just flare in the atmosphere and not removed by the "welding glass" filter being used.

Dr. Brooks says that it is an unsolved mystery that doesn't make sense under the theories of the RET sun.I fail to see any connection between the photos of the sun and any mystery about the temperature of the sun's corona.
Will you show that he is wrong and that it does make sense?
Or, will you continue to present unsolved mystery as fact that we need to disprove?
Yes, Tom's claim seems to be that the sun stays the same size because it is in fact a projection on something in the atmoplane. The problem, as I pointed out in my earlier post, is this turns a LOT of the FE hypothesis on it's head. It's no longer possible to say how high the sun is, the standard 30ish mile diameter is now wrong, it now needs to be a more focused light source in order for the entire sky to not be lit up, and it does nothing to help explain how a sunset happens or why it doesn't change size during the day (under this paradigm it should actually grow LARGER throughout the day). But he remains hung up on apparently not being able to grasp that the corona (which isn't generally seen) being hotter than the surface of the sun, has no bearing on why at least some images have parts of the sun seemingly brighter than other parts.Dr. Brooks says that it is an unsolved mystery that doesn't make sense under the theories of the RET sun.I fail to see any connection between the photos of the sun and any mystery about the temperature of the sun's corona.

No-one here is a solar expert but there is plenty written on the topic, such as:
Why is the Sun's atmosphere hotter than its surface? (https://www.wired.co.uk/article/sun-coronal-heating-mystery)
Strong Evidence For Coronal Heating Theory Presented at 2015 TESS Meeting (https://www.nasa.gov/feature/goddard/sounding-rockets/strong-evidence-for-coronal-heating-theory-presented-at-2015-tess-meeting)
And "science" is quite prepared to say that many things are not yet solved.
On coronial heating, there are hypotheses which explain it, but to my limited knowledge, none that could be called "the theory" as yet but I could easily be wrong.
But in the end, this has nothing to do with the topic, which is "How do sunsets work?"
I posted a few photos as evidence that the sun's angular size does not change from solar noon to sunset, apart from some slight reduction in height.
That does not fit with any flat earth explanation of sunsets.
The sharpness of the sun's image does not seem to fit with any explanations in "Magnification of the Sun at Sunset".
Where did LoveScience solve one of the "most significant unsolved problems in astrophysics"? Please quote it for us.
I am not talking about that glow on the outside of the sun in the 12 o'clock image. The sun is inconsistently bright.

I don't think my questions have been answered so far, or maybe I simply overlooked it. It feels like this discussion has gone astray.1. The sun only 'shrinks' at sunset. Both pages are correct. The size doesn't change during the day, then at sunset the sun appears to vanish/shrink.
1. Does the visible Sun-disc shrink or does it not shrink? Which Wiki-page in the FE-Wiki is correct and which one is false?
2. Within the FE-model, what causes the visible Sun-disc to suddenly (over the course of a few minutes) appear and disappear at sunrise/sunset?
