This has been bugging me for a while. I'm just not seeing how the case for a flat Earth is any stronger than that of a round Earth. Both appear to rely almost completely upon the work of other people, or questionable experiments. Just what is the actual case for a FE?
"It looks flat"
I see this a fair bit, although it appears to be both the weakest plea and a fall back for some. Not only is this highly subjective (I look out my window and it appears anything but flat; welcome to hill country) but the given math for a round Earth means simply looking flat doesn't rule that out. It comes down to a sort of 'debate' between which one feels is simpler. A sphere, or a flat surface. While a sphere might be mathematically simpler, our daily lives seem to suggest flat is simpler at times. Either way, this doesn't seem all that universally compelling.
"ENaG/Bedford Level"
Here is where I'm personally starting to run into some problems. Not only was this experiment at a time before images could really be done to properly capture everything, but the location has produced a fairly wide array of results from different people, including one using it to conclude the Earth is concave! But really, why should we trust ENaG any more than any other literature? Has any member of the Society actually recreated the experiments described herein? If you have not, how can you trust them? Why are these experiments trusted more than others? It seems these should be treated with the same amount of caution and skepticism as any other set of experiments, but they don't seem to be.
"The Bishop Experiment"
This is an interesting one. I've come across a fair number of threads about this one as I've been back browsing, and there are a disturbing number of things not quite holding up to close scrutiny. Pictures have been shown, but many don't match what has been pointed out, and there's the issue of a much closer beach visible from the same location. This also unfortunately suffers from the problems pervasive to a number of similar experiments, in that the air over water is in a near constant state of flux, and cannot truly be measured for a proper control. An issue for much of ENaG as well. This one seems like it could be a useful tool, but it seems to need better documentation.
"Zetetic Cosmogony"
Been reading some of this recently, as it too is listed under 'experimental evidence' on the Wiki here. I haven't seen much in the way of experiments in this book at present, merely quoting the words of others. Which once again raises the question of why we should believe both their words, and the conclusions being drawn about them. If there's something more tangible in here, I would be appreciative if someone could point me to it. But I see much of the same statements as ENaG makes mirrored, nearly all without even an apparent attempt to document showing them, unlike ENaG.
"Lady Blount"
Here is stated to be a close repeat of the 'Bedford Level' experiment. The wiki calls this 'one of the first to peer review' that bit of work. The description provided however seems wholly unsatisfactory. We are told about a sheet seen from one end of the canal at the other. That the sheet is even seen reflecting in the water. But we don't know the height of the sheet, nor do we know how much was seen. The claim is that there was a picture taken, but this is not provided on the wiki.
This appears to be it, but it too isn't particularly satisfactory. Once again we are left with trusting the words of another.
Based on all of this, I have to ask one small question. What makes any of these 'better' than the sources for a globe Earth? Every one is at best a written personal account with no useful visual evidence. Even The Bishop Experiment has issues with both it's documentation, and evidence. Simply trusting these sources seems the same as trusting the sources which describe the Earth as round. Am I missing something? The zetetic approach here, to me, would say that one cannot be sure of the shape of the Earth. That's obviously not a very compelling conclusion, and if I have missed something or you feel I'm misrepresenting something I would encourage leading me in the correct direction. I've attempted to be as neutral as possible in my observations and statements here, but I'm only human.
