Where can i find proof that the curvature of the earth is not visible to the naked eye at sea level?

Question

OK i have been asking this for a couple of days heres the details i know when you are at sea or a desert it appears that the horizon is curved but i propose that is an optical illusion caused by light bending there has been many answers with varying information for instance ppl have said that you can see 15 miles 26 miles a hundred miles a couple of hundred mile someone even said you can see about a thousand miles what i want is some concrete evidence that when you see the horizon appears curved its not true somebody please help with some hard facts or a website link thanks:)

Answer 1

You won't find your proof because it's not true. Atmospheric refraction actually goes in the other direction, that is, it enables you to see a little further over the horizon than you could otherwise. So the appearance of ships disappearing over the horizon is real, it's just slightly reduced by the refraction. If the Earth were flat it would appear bowl-shaped.

Answer 2

the cleanest logical proof for a flat earth is likely Xenophanes of Colophon(~478bc), but he required in his proof a brand new and unique sun every day that flew away in a straight line forever(think of fireballs from a Roman candle). And the reality is different. He also thought that the earth went down forever, no other side, kind of like a flat topped column. Like I said, the reality is different
He also based much of his argument on the effect of the apparent meeting of parallel lines at the vanishing point, claiming that the plainly observable curve of the horizon was an optical illusion caused by the effect of the almost infinite distance to the edge of the earth, like I said the reality is different

Answer 3

Visible curvature of the earth is visible at a range of fifteen miles. Anything beyond that point, visually, part is lost to the horizon. This is why it can sometimes seem like the trees on the otherside of the lake is "growing" half way out of the water.

My source has a very good pictorial of this

Answer 4

this is simple if you search for our capabilities to see at a distance and you would be able to answer how far we can actually see. Also remember that been at sea lever means that you are at the level of the sea, and could easily misinterpret a fall in the horizon below sea level as a curvature.

Answer 5

Honestly, you have to accept the answers people are giving you. Go to the beach and look at the horizon on the ocean. It is quite clearly curved.

Answer 6

Sorry but, our old buddy Christopher Columbus proved a while back that the Earth is round, it almost got him thrown in jail too. Just watch the sail boat sailing away on the horizion, the mast disappears last, there is still a flat Earth society, you could join them, or become a liberal, and think that everyone in the mid east is "Just like us", and "nice", and not trying to kill us all.

Answer 7

For you to be able to say that the horizon is not curved is akin to saying the earth is flat! The maths behind how far you can see is given at this site:-

Answer 8

Distance to the horizon is a function of height of eye. See any nautical almanac for h.o.e. tables.

Answer 9

Well, let me put it this way, i don't know, but wot u could do is ask a number of people about wot they fink and see wot u come up wiv! Like a survey...
bye...

try this. or type into your search engine "science of the curvature of the earth" hope it helps
