if the earth is flat, people in south(people over the equator) should see the Polaris like the people in the north do. But they actually don’t. Can someone please explain this?

Or is it that the flat earth has an oval surface, so the people in south have their vision blocked by the curve? but is it curved that much?

thanks a lot.
This is simply not true.

Some evidence to support this point would be lovely, alternatively just concede that you can't possibly make such a definitive statement ?
What evidence would you like?

Can you see your neighbor's back door?

Why not?

Something in the way?

No...my written statement stands.
Kangaroo logic might be sufficient to make some sort of claim, but certainly not to disprove the OP.
I'm not trying to disprove the OP as he never wrote a truthful statement to begin with.

The ability of humans to perceive objects is roughly limited to 350 km, regardless of the shape of the earth.

The OP wrote that people should be able to see Polaris from wherever they are standing on the earth if the earth was flat.

That statement is just flat out false.

The sun is 150 million km away and I can see that.  Your statement is just flat out false.  This is a fun game isn't it?
The Sun is a lot closer than that, according to many sources.

I have performed a similar triangles measure of the sun.

I believe it is approximately 5,000 miles away from my location during the summer months, at around 10:00 am.

But, really I find all of  this quite rich!

Here, AATW writes:

Does his happen with Polaris? No.
But here, he flips the script and starts arguing with...himself:
Of course it is - the observed magnitude is. The further you are from a light source, the dimmer it appears.
Shine a torch right in your eyes and it's uncomfortably bright. Observer it from 50 yards and it's much dimmer and smaller.
So, which position are you arguing again?

It's quite simple. In RET you are no further from Polaris at the North Pole than you are at the equator.
Because in RET Polaris is over 300 LIGHT YEARS away from earth. So a few thousand extra kilometers here and there on that scale makes no difference, you would not expect to see any difference in apparent magnitude.

If FET claims that the stars are much closer though then you would expect the magnitude to dim the further south you go as the difference in distance would be significant. That isn't what is observed.

I'm not claiming anything. You said

Once you are far enough away from an object, you can no longer see that object.

So if your claim is that we can't see Polaris from the southern "hemisphere" because you're too far away then you should surely be able to provide some data which indicates that the further south you go the dimmer Polaris gets until it can no longer be seen.
In fact what we observer is that the further south you go the closer to the horizon Polaris gets until it can't be seen because it is "under" the horizon.
RET has an explanation for that observation. Does FET?

Yeah I wrote that.

That statement is undeniable fact.

What data do I need to provide that Polaris would get dimmer?

Even the Sun gets dimmer as it moves farther away...

Yeah, and I have provided it here.

Well it would help if I knew what FE model you were talking about

I'm going to respond as if you are talking about this model or some model which is relatively similar to this.

1. The place you are calling south pole does not exist in this model. Can you please mark on this map what point you would like to consider the south pole. This is the biggest problem with answering a question in these types of models because you are trying to compare a single square miles to a circle composed of thousands of square miles which are thousands and thousands of miles apart.

For the sake of trying to give you a few possible responses i'll just say that the south pole can be any random point on or around the outer perimeter.

2. You can't see the star from the outer perimeter because of the way the light refracts through the vacuum then dome and atmosphere (for models that have a dome)
3. You can't see the star from the outer perimeter because of the way the light refracts through the vacuum of space then the atmosphere (for models that don't have a dome)
4. You can see the star from the outer perimeter
5. No one has been to the outer perimeter (for a large numbers of different reasons depends on the subset of this model) so no one knows if you can see the star from the outer perimeter or not.
6. You can't see the star from the square mile randomly picked as the south pole because the RE south pole is on the opposite side of the circle.
7. You can't see the star from the outer perimeter because it's too far away.
8. You can't see the star because of limitations to the human visual system.

i did not say south pole, i said people in the south, and that “in the south” means “over the equator”. but that’s alright, i guess in that map, the south pole would be the circle line.

so if you can’t see the Polaris in the south in FET, it may be because of refraction?
i would like to know how it refracts, the way it goes. i’m not able to simulate it by myself because i don’t know what a dome is. is it the curve? or something else. i really like to know about the FET model, even if (maybe you)and i don’t agree with it.

If the figure is relative to objects not emitting their own light, then why is it relevant, seeing as Polaris does in fact emit its own light.

Polaris has been observed to be consistently directly overhead at the North Pole. From there, it drops by one degree in the sky until you get to the equator, where it is at the horizon. This phenomenon has been consistently used for celestial navigation for years. Sailors would use an instrument called a sextant to precisely measure the angle between Polaris and the horizon, which allowed them to gauge their precise latitude. However, this falls apart if any flat earth model is used. In the unipolar model, latitude lines are a regular distance apart, so let us use this to construct a mathematical model. If there is a star at a height of any number of units, and a viewer is directly beneath it, then it will always appear to be at an angle of 90 degrees to the horizon. If the viewer is 1 unit away, which will represent 1 line of latitude, then the height of the star does matter, so let us set it at 1 unit as well. If this is so, then the viewer will perceive the star at 45 degrees above the horizon, rather than 89. So, the height of the star must be raised. In fact, it must be raised to approximately 57.28996 units. With a latitude width of 69 miles, this works out to 3953.01 miles up. That's high, but nowhere near the RE number. However, the numbers diverge as one travels south. As the viewer moves away, each degree away results in a drop in angle that is slightly less than 1 degree, and this disparity gets worse the further the viewer travels away. At 45 units, the viewer would see an elevation of 51.8 degrees, which is 6.8 more than expected. At 60 degrees away, the viewer sees an elevation of 43.65 degrees, which is 13.65 more than expected. At 70 degrees, the viewer sees an elevation of 39.27 degrees, at 80 they see 35.59, and by the time the viewer reaches 90 degrees and should see an elevation of 0 degrees, or in other words a star on the horizon, the viewer sees an elevation of 32.46 degrees. Obviously, something is going on. This something is the sphericity of the earth.

If a similar scenario is constructed but with the viewer on the side of a circle, then an interesting phenomenon occurs. As the viewer moves over the side of the sphere, changing latitudes, the angle of the star, positioned above the North pole, can be found. If this is found relative to the viewer's horizon, or the tangent at the point that the viewer is at, then the angle is much less than the supposed angle IF the star is 1 unit above the north pole. However, in this scenario, as the star is moved further and further away from the north pole, the angle observed does not pass the theoretical angle. Rather, it approaches it. If a viewer is at 80 degrees and the star is 10,000 units away, then the observed angle is 79.899. If the star is 100,000 units away, then the observed angle is 79.990. With the RE figure of Polaris being 433 lightyears away, that works out to the star being 3.688E13 units away. This would make the observed difference tiny.

The results speak for themselves. One scenario, Flat Earth, fails in this scenario, while the other works. This is without using any fancy math, anyone with a basic understanding of trigonometry can crunch these numbers. What does Occam's Razor say?

That discussion about Polaris makes fascinating reading.  Yes the apparent brightness (visual or apparent magnitude) does vary for a number of different reasons. Some of those reasons relate to physical characteristics of the star itself (i.e. its a variable star) others due to their elevation. or angle above the horizon.

Taking Polaris specifically.  As an example of a classic Cepheid variable, Polaris pulsates. This makes the absolute magnitude vary a little as well since absolute magnitude depends on both the radius and the temperature of a star. Absolute magnitude is the apparent magnitude as observed from a standard distance of 10pc or 32.6 lightyears. That allows us to compare directly the luminosity of one star against another. Some stars appear bright to us because they are nearby (Sirius for example) while others appear bright because although they are more distant, they are also very luminous (Deneb for example).

The apparent magnitude of Polaris will be the same for all observers at the same latitude. However atmospheric extinction will also cause a dimming effect of the apparent brightness of a star to observers at different latitudes. This will be greatest for an observer just north or the equator and least for an observer at the north pole because they will be looking through the thinnest possible layer of atmosphere.

Whatever latitude you are stars near the horizon will appear dimmer. So if I am looking at a star near my south horizon at 45N say then that star will appear dimmer to me than it will do for an observer further south who will see that same star higher up in the sky.

So Totallackey is approximately right in some of what he says, but wrong in others.  His answers have been carefully worded to as to be true to an extent but also so that they suit his flat Earth belief. AATW is also right in that the differences in brightness that we see have nothing whatsoever to do with variations in the distance of Polaris from the observer.  However apparent brightness of stars drops off according to the inverse square law of light intensity.  A star equal to Polaris in absolute magnitude but twice as distant would appear to us only a quarter as bright.

This is an interesting quote from Totallackey which I note he made earlier on. I wonder what leads him to conclude it?  Across land you certainly can't see 350km. On the other hand the Moon is an 'object' which is 384,400km away and then the planets are 100s of millions of km away.  So what leads him to say this is beyond me.  It is true though that seeing across millions of km into space doesn't depend on the shape of the Earth.
