Even if the sun were 4,517,820 miles away from the earth, wouldn't it appear to always be the same size, given that it's supposedly so far away? But the sun, in reality, gets smaller in appearance as it goes away from us, and this indicates to me that the sun is not far away at all, but quite close and above the earth. It's not absolute proof, but just evidence to me.
Thanks. This video debunks the notion that the sun never gets smaller when it's setting. Sometimes it does. Sometimes it doesn't ... although I've seen a guy who made a video showing that it gets a little bit smaller no matter what, even if it's not "smaller enough" to make it obvious, where he took still shots and measured the size of the sun.
So, it's clearly demonstrated that things can get magnified when viewed through the atmosphere. As objects get lower on the horizon, you have to look through MORE atmosphere to see it. But what kind of atmospheric distortion would cause the sun to APPEAR to get smaller? Only thing you can say is that when it was higher in the sky, it was being magnified, but then when it got closer to the horizon it was magnified less and less ... but that's the opposite of what we normally see, such as with the moon being larger near the horizon.
David Weiss has taken some video from a drone where the sun never sets but merely fades away.
I've seen video from the weather balloons (those at about 120,00 feet), and when it's in the right position, the sun does clearly appears to be headed TOWARD the balloon and getting larger. You'd expect a lot less atmospheric distortion at 120,000 feet.
And, then, it's been pointed out with those weather balloons at 120,000 feet that from one end of Kansas to another you would expect 120,000 feet of curvature, the same amount as the altitude of the weather balloons. That's an enormous amount of curvature that is not evident anywhere. You would clearly see the horizon line dip below eye level.
About 16 seconds into this simulator video is what it would look like at 120,000 feet, but the horizon line remains at eye level.
That's why Nei deGrasse Tyson had to do damage control with his "that stuff is flat" video, where he had to claim that you couldn't see any curvature at 120,000 feet (where it used to be claimed that it could be seen from commercial airplanes at 30,000 feet). Now that amateur balloons have gotten up to the 120,000 feet level, they couldn't hide behind doctored NASA images anymore with the wide angle lense. So he had no choice but to claim that curvature would not be visible at all at 120,000 feet (as per the Red Bull jump).
