Thought I replied to this already.
About beers law. How light, no matter how bright cannot travel through a media for infinity. As particles (H2, CO2, water vapor, dust, etc) deflects photons, eventually the light cannot travel through it all, and we see dusk, and eventually darkness.
Think about shinning a powerful flashlight from one side of a large lake to the other, of course people on the other side can see it. But if you put the light under water, and they put their head underwater, they cannot see the light because the water media is too dense and deflects all the light before it reached the other side. Air is the same principle, just much less dense than air. But it's still why light can shine across the world.
Also, the sun is at the same elevation, it just appears to rise and set because of the laws of optical perspective. Stars are the same. They are all circling around in a perfect circle with Polaris always on the center for thousands of years. As stars get father from you they collapse onto the horizon. Just like the sun.
It's really simple.
Agree! I'm very familiar with the concept.
However, when light travels away from the viewer, it simply fades away, growing smaller and smaller until we can no longer see it. The sun does not behave this way.
Precisely! I already confirmed that in the very first sentence of my comment on this. Our line of sight is never interrupted, and yet it appears to drop below the surface of the planet long before it gets smaller/fades as a flashlight would.
Why is that?
The sun goes out of view because collapses into the horizon. It's not as small as a boat or an airplane.
The sun is always about the same distance from you. When it rises, it's roughly 4-5000 miles from your view, when it's above your head, about the same, and when it sets, about the same, so we would not be able to notice small changes in it's size because it's pretty much always the same distance from us while in our view.
Optical range is why it rises and sets. It's just optical laws of lenses and our eyes. So, just to close this point, the sun does behave as we observe, it's local and relatively small compared to the theory, some people have calculated it's about 30 miles in diameter. You would just need strong filter to see the outline of the sun and do some trig. But it's not gonna be super accurate since you are using triangle math on both sides of the sun to determine the diameter. So about 30 miles wide is close enough.
So, about the sun never changing elevation. I don't think you get it still. It doesn't change. You just perceive that it changes due to the laws of optical perspective. I tried to explain this. As objects get farther from you, they collapse onto the horizon. It's very simple, but somehow people don't easily grasp this.
Think about a row of street lamps. You are standing under one of them. You look up 90 degrees to see it. Then the one that is 100 feet away, you do t look up at 90, more like 75. Then the one after that is a bit lower. And on and on until you see about a mile down the road, and the street lamps is so low, it's almost level with the street, you are looking at it nearly 0 degrees above the horizon. And at some point, you can't see the street lamps anymore. The get too far away (plus they are small and not super bright like the sun so, beers law action happens sooner
Well, surely this changes to some degree. An object that travels a path above me will be closest to me when it's directly overhead, and further away at other points of its traveled arc. I understand that the the relative difference may not be so large, but the sun certainly isn't always about the same distance away.
If you're going to claim that though, it definitely brings into question the aspect of it setting. It seems odd that the relative distance doesn't change much, but the view we have of it changes so drastically.
Interesting! The figures I've seen are much larger, even those against current teachings. Where does this figure come from?
...Yes. This is what I've been saying from the beginning...
As objects "collapse" into the horizon, they get smaller as they get further away. We see this all the time every day. However, with the sun, it doesn't. You've explained this by saying the sun's relative distance actually doesn't change from the viewer, essentially saying the sun doesn't get further away, and we observe that it doesn't get smaller.
So, we now have the sun behaving differently from other objects, and I guess I'm still confused as to why.
These streetlamps are considerably further away as you go down the road. You said the sun stays relatively the same distance away.
Yes, I said 'about' it's because your eyes, all lenses, have a range of view. The sun comes into your view, and it's 5000 miles away. When it's directly over your head, it's 4500 miles above and when it's sets it's 5000. Just using as examples, the distance is approximate.
I've seen video of the sun fading out, beers law, but to see that you need to be miles high and zoom in on the sun with powered lens. Guess what colors you see last. Why?
i don't know of any 'teachings' because there isn't actually a FE cult like we've been told, but I'm sure you can find all kinds of ridiculous psy ops if you look for them. Im sure if I tried, I could put together an experiment to measure, so could you, it's just trig. There's a few different ways I would approach measurements, but once you figure out the curve doesn't exist you know it's not a globe and I don't care to get accurate on exactly how large the sun is because it's not important to knowing we aren't on a globe.
I have never seen "teachings" about fkatvea
