Being "pretty sure" refraction makes something look bigger and or smaller...
I am
absolutely certain that refraction can make something look bigger or smaller. I am
pretty sure it
usually makes the sun look smaller during sunset.
...sometimes is a far cry from being absolutely certain the Sun doesn't ever change apparent size during the course of one day, which would be impossible if it was 93,000,000.
I didn't say the sun doesn't ever change apparent size. I said refraction
can cause
slight changes in apparent size.
You can keep hand waving as much as you want, but your effort to somehow make this something incompatible with FET is ignoring the fact that it is also incompatible with RET.
The slight changes in apparent size (15% decrease) demonstrated in the video is incompatible with the 50% decrease in size predicted by FET.
The slight changes in apparent size demonstrated in the video is completely compatible with RET, when taking into account the following factors:
1. bad measurements by the video uploader
2. crappy filter that doesn't block out the glare
3. refraction (probably not a significant factor in this video)
I have no idea how any of this is "hand waving". It seems pretty clear cut to me. Did you pause the video at 1:44 and 2:12 to observe the bad measurements? Did you notice the large amount of glare compared to a better filter like
this?
