Does the sun change size.

Hello again
I just spend a day viewing the sun through a sheet of Mylar. I viewed the sun about every 3 hours from sun rise to sun set. The sun never changed size from sun rise to sun set. Does this mean, in the flat earth theory, the sun changes size to your own perspective so that it can remain the same size while doing this disk orbit? or is there a different explanation.

I just want to point out that there is no electronics or mirror on a sheet of Mylar. All it does is block out 99.9 percent of the suns light to make it safe for viewing.

Well, from what I have seen, the simple answer is, no.  Of course within a degree or so of the horizon, especially at sunset there is often distortion that changes the shape.  Same for the moon.
Don't ask me how it might be explained with a moon 3000 (or whatever) mile above.

It does keep the same size, but is magnified by the atmosphere. Somehow. I still do not know how and by what factor. I asked about the details here: http://www.theflatearthsociety.org/forum/index.php?topic=65388.0#.Votapo-G_F0 No answer yet.

Thanks for that response. At least they try to answer it.

Some kind of magic air magnification, which only affects the sun, and whatever the atmospheric conditions are, it will magnify the sun exactly the amount to keep it the same apparent size.

That's about it really. 

How do the flatties know this phenomenon exists?  Well, the sun stays the same apparent size all day long doesn't it?   

I think it's safe to say that we've won this debate.

Won what debate?

This one. Unless you care to defend your position.

What was the claim that I was supposed to refute?  The one that the sun never changes size?  It was a troll claim, and you fell for it, lol.

It should change size if its going around us like a giant halo. As it moves away from us it should shrink in size. And actually I forgot where but some flat earther said that it does change sizes.

At 93000million miles away the rotation of the earth should have no effect on the size of thesun but it changes in size significantly.Just look at how far away it looks and sunset then look at it miday. Also weather balloons taking pictures at the same time of day,but different times of year show the sun higher in the sky then sometimes just above the earth.
Sundials, were designed when the world thought earth was flat,non of them would work today on a globe because the angle of the earth effectively changes through 46%every 6 months the one on a temple in India is accurate within 2 mins if used correctly.
Hold a stick up right on the earth tilt it through 46% and see if the angle of the shadow changes at any time of day provided the sun is shinning.Whe sundials don't work the earth may be a globe.How simple is that test,if the shadow doesn't change position it a globe.Whatch someone from this globe earth site rubbish the claims without one constructive comment.Eric Dubay said this is a bogust site he's right.

It may change in size as viewed from a particular point on earth.  I suggest you contact someone else who is viewing at their midday to see what they observe.

should I just take pictures of it through out the day through my Mylar and post them. I'm pretty sure that would show the sun staying visibly the same size all day. Then again if I did that the response would be that I edited them.

Evidence, please.

Just look at how far away it looks and sunset then look at it miday.

The Sun and Moon look larger close to the horizon than they look when high in the sky. It's an illusion. Take some photos and measure. They're the same actual size. Do you have any objective data that says otherwise? But why would the Sun and Moon appear larger (because they're closer) when they're setting than overhead, anyway? That's the opposite of the FE explanations I've heard here.

OK? And...

Sundials again? You never replied in the thread you started asking whether sundials would work on a globe (they work just fine).

The change in the Sun's declination is closer to 47° over the course of a year, but whatever. The non-perpendicular angle of the Earth's axis to the Ecliptic is the largest, but not only significant, component of the Equation of Time, which is needed to convert apparent solar time to mean solar time. It amounts to about 10 minutes difference at the extremes. To claim "sundials wouldn't work" because of this is a bit of an overstatement, to say the least.

the one on a temple in India is accurate within 2 mins if used correctly.

Within 2 minutes of what? Apparent solar time? That's not hard to do with a well-designed and sufficiently-large sundial. What does "used correctly" mean in this context?

Hold a stick up right on the earth tilt it through 46% and see if the angle of the shadow changes at any time of day provided the sun is shinning.Whe sundials don't work the earth may be a globe.

Do you think the shadow wouldn't change when you wave the stick around if the Earth were flat? If it were spherical? Why?

How simple is that test,if the shadow doesn't change position it a globe.

On what basis do you say this? You do realize that a good sundial has the gnomon aligned with the Earth's axis of rotation, not just in some arbitrary direction, don't you? There's a reason for that. Do you know why?

Whatch someone from this globe earth site rubbish the claims without one constructive comment.Eric Dubay said this is a bogust site he's right.

Your claims get "rubbished" because they're, well, rubbish. That's all. If you have questions about the answers you get, ask them.

Sundials, were designed when the world thought earth was flat,non of them would work today on a globe because the angle of the earth effectively changes through 46%every 6 months.

Not true!  They work fine on the Globe!
Primitive Sundials were constructed without reference to the globe, but after the work of Abu'l-Hasan Ibn al-Shatir (over 600 years ago) they were certainly based on a global (though not necessarily rotating) earth, as the stationary globe was widely accepted then.

Sundials do come in a number of types.  But in all of these making the gnomon parallel to the Earth's axis means that the sundial time is unaffected by the season.

• In the usual flat garden sundial the base is horizontal and the "gnomon" fixed in place at the time of manufacrure. This means that the gnomon points north - south at an angle to the horizontal equal to latitude where it installed. In practice a limited number of  different sundials are manufactured for various  latitudes. See in: https://en.m.wikipedia.org/wiki/Sundial#Sundials_with_fixed_axial_gnomon
• There is also the equatorial sundial which is described in https://en.m.wikipedia.org/wiki/Sundial#Equatorial_sundials

But, the bottom line is that all sundials work on the Globe earth.  The rules for setting up sundials simply do not work for the flat earth with sun circling above.  Yes, on the north pole it would work with a vertical gnomon, but just try it on the equator with the gnomon horizontal!

I suppose you do realise that in your flat earth model the sun moves from circling over the Tropic of Cancer in the northern summer to circling over the Tropic of Capricorn  in the southern summer.

This reference is interesting, showing that the "modern" sundials were first developed in the middle east:

The idea of using hours of equal time length throughout the year was the innovation of Abu'l-Hasan Ibn al-Shatir in 1371, based on earlier developments intrigonometry by Muhammad ibn Jābir al-Harrānī al-Battānī (Albategni). Ibn al-Shatir was aware that "using agnomon that is parallel to the Earth's axis will produce sundials whose hour lines indicate equal hours on any day of the year." His sundial is the oldest polar-axis sundial still in existence. The concept later appeared in Western sundials from at least 1446.[9][2]

It should, like this diagram is telling us:
