Watched it many times. Lots of miraging. The shoreline visually vacillates upwards and downwards. Refraction cause all kinds of visual anomalies. But that's not the same as an object moving further away and disappearing over the horizon, from the bottom upward.
I agree 100% that it's not the same. But you must admit that, in a situation where an object is moving further away and disappearing over the perceived ocean horizon from the bottom upward that there can be all kinds of visual anomalies affecting the path the light from the object takes before hitting the eye of the person observing the object.
Sure, but the exact same visual refractive anomalies have to be present for each and every sunrise and sunset for every observer around the world. Hence the word, 'anomaly'.
Yes, watched the video. Yes, the shoreline vacillates up and down due to refractive miraging. Did the shoreline disappear from the bottom up, stay that way for 12 hours and then rise again back into view? The timelapse has literally nothing to do with the "sinking ship effect" other than the fact that refraction can pull things up and push things down.
Since we both agree that refractive mirages and other visual anomalies can pull things up. As demonstrated in the video these optical issues are "pulling up" the water between the shore and the observer. causing the shore to disappear, from the bottom up. Over larger distances this refraction effect would be larger because the light would be interacting with more things like air molecules, water vapor, particulates etc on a much larger scale. It's the FE claim that this "pulling up" effect (that we both agree can happen) is happening when an observer sees a ship traveling away disappear from the bottom up.
Yes, the pulling up effect
can happen as well as a pushing down effect. But the point is, why does a sunset go down, bottom to top and a sunrise reveal itself from from top to bottom, separated by 12 hours or so, like clockwork? Why does a ship going over the horizon go down, bottom to top and when coming back over the horizon reveal itself from top to bottom? What magical refractive property knows when to mirage an object up and then mirage it down?
Again, the sun is a great example of the sinking ship effect. Today, if I'm standing on the sand at Ocean Beach here in San Francisco looking west out over the Pacific at sunset, I'm seeing a 3000 mile high, 32 mile wide FE sun disappearing completely bottom to top below the horizon by some means of a refractive mirage anomaly? And I see that same anomaly everyday? At exactly the time our apps predict?
As well, today at sunset, the 3000 mile high, 32 mile wide FE sun I'm seeing disappear, I'm actually able to see it without the aid of any magnification even though it's 7200 miles away from me over Australia:
A few hours later if I brought my telescope along, I should be able to pull the sun back into view even though it's now over Africa. But I can't, there's something in the way.
