lol, you are claiming that refraction only works in one direction. Discussing this with you is like explaining relativity to a child.
You really seem to enjoy acting like a broken record.
This has already been explained to you.
For the same situation, refraction only works in one direction.
If you change the situation, you can have it refract the other way.
From what is known about the atmosphere, typically light will refract downwards making things appear higher.
It is only transient events which have light refract the other way. That cannot explain the everyday occurance of sunsets.
You are asking me to make guesses
Well thanks for admitting you have no idea.
See, the real scientists (and even plenty of lay-people) know how refraction works.
And that is the key difference.
The things you ask us to explain, you have no better idea/explanation. Meanwhile the things we ask you to explain are well known and verified in real science.
We know that light bends towards the normal of a higher refractive index medium.
We know that for air, the refractive index is related to density such that more dense air will have a higher refractive index.
We know that in general, the air is less dense the higher you are.
All of this will lead to the conclusion that, in general, light will refract downwards through the atmosphere and thus make objects appear higher.
That is not how Zeteticism works. We do not just make guesses; we make observations, analyze the data, and draw logical conclusions based on the best data possible.
That is nothing like what you FEers do, that is pretty much what real scientists (those that conclude Earth is round) do.
You FEers make a guess, that Earth is flat, then make more and more guesses to try and explain away observations.
If you were going to make observations, analyse the data and then draw logical conclusions, you would have concluded that Earth is round.
This thread is on perspective and the effects thereof.
We can make observations, of numerous objects of known size and position, and find that they shrink the further away they go. We can even fit these to formulas, where their apparent angular size is given by 2*atan(s/2d), where s is their real size and d is the distance to them. (it gets more complex when you aren't viewing them straight on.
We can then apply this to the sun (with an appropriate filter to remove glare). We note that it remains roughly the same size.
This indicates it must remain roughly the same distance away from us.
Thus the best conclusion based upon that is that from our perspective, the sun is circling us, or a point near to us.
By taking these observations from various places on Earth we conclude that the distance to the sun must make the distance as you move around Earth insignificant.
This, combined with different time-zones leads to the conclusion that the sun can't be travelling over a flat surface.
This is what real zeteticism would lead to.
