I encourage everyone to dig deeper. Don't just speculate and say, "it could be refraction." Dig in and figure out whether or not it really could have been.
The problem is that no one does dig deeper. They say look this picture, based on what I see, proves the earth is round.
Based on that logic, based on the time lapse shown the earth alternates from between being flat and being round throughout the day.
Thanks for pointing out the timestamps, iampc. I've added them to the Sinking Ship Refraction Wiki page.
I really wanted to find some point where there was just a few minutes apart and no temperature difference whatsoever so no one could claim that temperature was the sole cause of the data being different.
I would gladly consider marking some of these predictions/observations as RE evidence if they even attempted to outline what is happening optically. Optical variables, atmospheric variables, and things like refraction are many times outright ignored.
People continuously say this refracted observation matched the round earth predictions in a vacuum. THE EARTH IS ROUND. When literally a few seconds later the observation has been demonstrated to change.
