Why can we see objects, that mathematically we should not be able to see?
Is it possible to have a decent discussion without people losing their shit?

Two examples :
October 16, 1854 the Times newspaper reported the Queen’s visit to Great Grimsby from Hull recording they were able to see the 300 foot tall dock tower from 70 miles away. On a ball-Earth 25,000 miles in circumference, factoring their 10 foot elevation above the water and the tower’s 300 foot height, at 70 miles away the dock tower should have remained an entire 2,600 feet below the horizon.
In 1872 Capt. Gibson and crewmates, sailing the ship “Thomas Wood” from China to London, reported seeing the entirety of St. Helena Island on a clear day from 75 miles away. Factoring in their height during measurement on a ball-Earth 25,000 miles in circumference, it was found the island should have been 3,650 feet below their line of sight.
There a numerous current day examples too

The distance between Grimsby and Hill isn't 70 miles, it's more like 25km

I assuming 'great Grimsby' is not the same as The english town of Grimsby.
A few quick searches show it might have been a rich guys house
n/a Rockran 2017-01-03
It's referring to the Grimsby dock tower. Located in Grimsby.
Your quote even says "they were able to see the 300 foot tall dock tower"

The wording is fine. The problem is you.

Go to Google street view in Genoa - Can't see the island.
Well that was easy.

I'm not sure if that (google street view) counts as scientific evidence.
n/a Rockran 2017-01-03
Not sure if just saying you can see the island without anything to back it up counts as evidence, scientific or otherwise.

Downvoted as you've been spamming this sub with these false examples from 200 years ago. Solve this and you win: Why is the North Star not visible in the Southern Hemisphere?
Your move.
n/a 435435435 2017-01-03
Oh no down votes
74) From Genoa, Italy at a height of just 70 feet above sea-level, the island of Gorgona can often be seen 81 miles away. If Earth were a ball 25,000 miles in circumference, Gorgona should be hidden beyond 3,332 feet of curvature.
Thoughts?
n/a EricCarver 2017-01-03
Why is the North Star aka Polaris not viewable in the Southern Hemisphere? Answer this simple question if you are not a shill and truly believe in flat earth. Or are you bot, bro?
n/a 435435435 2017-01-03
Yeah I'm a bot. Beep beep.
Your star question is unrelated to the op unfortunately
n/a EricCarver 2017-01-03
It is directly related if your point to the OP is this is a flat earth. Or are you not saying that? What is your point, 4353?
n/a Rockran 2017-01-03
Why can we see objects, that mathematically we should not be able to see?
Are you taking into account object height, observer height and atmospheric refraction?
n/a 435435435 2017-01-03
Yes, the height of the thing and the observer above sea level is taken into account.
I find 'refraction' in regards to the atmosphere somewhat suspicious. I the argument said reflection allows the observer to see items like building or mountains around the curve of the earth? Sounds odd
n/a OffMyFaces 2017-01-03
So you don't believe in refraction either?
How do you explain how the telescopes flat earthers use to see ships 'beyond the earth's curvature' work then?
It's ironic they claim refraction can't be the reason they see the ships, while using a refracting telescope to look at the ships.
n/a 435435435 2017-01-03
I didn't know what it was until yesterday. I said it sounds weird to me. To be able to see something that not there. Over the curve of the earth. Via Light retractions or some crap.
If we are win technical I did Nae say "I dont believe it"
n/a OffMyFaces 2017-01-03
Yesterday you didn't know what refraction was. And now that you've heard of it you think refraction 'sounds a bit weird'.
And that's your basis for thinking thousands of years of science is wrong?
And you need a curvature calculator because you can't work out 8 x distance2 - but you think hundreds of thousands of scientists have got their maths wrong?
n/a 435435435 2017-01-03
I had some concept of refraction in general not 'atmospheric refraction'. Pls do forgive my ignorance.
"thousands of years of science" is just lame hyperbole.
n/a TheMadBonger 2017-01-03
Unfortunately noone likes to talk about the math aspect of it. I tried this same topic a week or so ago and got the same "flat earth retard" comments it always brings.
You might be interested in this, it uses math and works with a 25000 diameter earth.

n/a TheMadBonger 2017-01-03
So his formula did not account for the factors above stated by wile e chicken? Is that what you mean?
n/a yokothespacewhale 2017-01-03
To answer your question, no. OP did not exclude important "factors" in his formula. He, in fact, presented no actual formula and wile e chicken posted the formula op should have used.
n/a TheMadBonger 2017-01-03
That formula is used is his experiment with lasers. (An experiment we can recreate he claims with a 600$ laser). So your saying this experiment isn't even using a valid formula?
http://www.wildheretic.com/concave-earth-theory/5/
n/a KiwiBattlerNZ 2017-01-03
His?
Actually, that page you linked contains a quote from someone else that claims to have done it, and this:
That page was created in 2013. It's now 2017 and there has not been anything else added to that site saying this guy has carried out the experiment and confirmed the results.
I wonder why?
n/a yokothespacewhale 2017-01-03
whew thanks for playing backup on this one. I'm getting exhausted.
n/a wile_e_chicken 2017-01-03
The earth doesn't curve 7.98in/mile -- it curves 7.98 inches in the first mile and drops off much more each mile after that.
The equation you want is: c = (2/3) * x2 where x = distance in miles, c = curvature in feet.

How can I see Polaris(the North Star) from the Southern Hemisphere? If we lived on a globe, once I pass the equator it should no longer be visible.
n/a DominizZzle 2017-01-03
You can't see Polaris from the Southern Hemisphere
n/a 435435435 2017-01-03
You can make your own thread of those questions. I am specifically curious about the Maths seemingly showing fe evidence in this discussion:
Like this:
74) From Genoa, Italy at a height of just 70 feet above sea-level, the island of Gorgona can often be seen 81 miles away. If Earth were a ball 25,000 miles in circumference, Gorgona should be hidden beyond 3,332 feet of curvature.
n/a Tamerlane-1 2017-01-03
That still isn't true, or at least you have not supported it with evidence.
n/a EricCarver 2017-01-03
Down voted as blatant falsehood. Polaris the North Star is only visible in northern hemisphere while the south cross is as close to a comparable southern equal.
Recommendation: think critically before you make a stance.
n/a brimstone18 2017-01-03
Lol.
n/a OffMyFaces 2017-01-03
You can't.
It's not possible, because every time a flat earther is presented with very straightforward information that demonstrates why the earth is not flat they either disappear or start spouting nonsense.
It's the flat earthers who lose their shit.
Flat earther logic goes like this:
I don't understand very basic science - therefore it's all the scientists who must be stupid

Hammer collides with nail at the fore end!
n/a DominizZzle 2017-01-03
Probably because the earth is NOT a perfect sphere. There are many massive mountains, valleys, hills, plateaus, trenches, etc. that can span miles and miles past where you can see. It's like when I drove from Colorado to Kansas and the mountains gradually "set" out of my view from the bottom up. But on a flat earth I would have been able to see the rocky mountains from the next state over.
n/a 435435435 2017-01-03
Apparently the earth is a pear shape...
Kansas is flatter than a pancake too
n/a DominizZzle 2017-01-03
Kansas is flatter than a pancake but you can't see 14000+ foot mountains a couple hundred miles away? Makes no sense
n/a 435435435 2017-01-03
Funny thing science isn't it
n/a Beneficial1 2017-01-03
An interesting theory I have been playing with.
Pretend for a moment the Earth has an awareness; It has a being and a consciousness. And it is very old and will live very long.
Throughout the life of the Earth since it is consciousness, decides it wants to organize itself differently.
Kind of like us. We choose different ideas and we expand our awareness and change very frequently in what we do.
The Earth shifts too. It changes. It alters it's organization. It's been a flat, one dimensional line, it's been a three dimensional triangle, it's been a solid sphere.
What is becoming now in our paradigm shift is the Earth 's reorganizing itself with our input. It is shifting, we are shifting. Everything is shifting, and expanding.
So what does that mean?
It means as we shift so does the Earth. Our perception of it shifts, And it shifts.
Does that mean into another shape?
Not really into another shape, but formed into an intelligence that we can communicate with.
Then we will find out what it means to be Earthlings.

I've humored this thought as well. Brian Mullen who's a structural/civil engineer who applies his knowledge to studying the flat earth theory is starting a "force the line" campaign to settle the score once and for all. However with that said, that same experiment went down under the name RECTILINEATOR EXPERIMENT in Florida at the end of the 1800s that yielded results saying it's concaved. Before anyone starts yelling it's been debunked, that is debatable albeit not the point. Point being, empirical data shows a flat plane and a physical test showed it to be concave. So a few thoughts come to mind, is the earth forever changing its shape based on thoughts, like we do formulate our own reality so if everyone believes it's a ball, it is a ball type of thing? Or perhaps it looks more like this? Either way, I truly wish we could find out before total world annihilation (regardless what shape it is)
n/a dmwil27 2017-01-03
If this in fact is a "Theory", why are we "Pretending" it has awareness? Where's the evidence for this other than something you dreamed up? I know it seems like I am being rude but, I am actually asking this question out of genuine curiosity. Also if it is so old, why does it feel to reorganize itself with our (people's) input? We would be relatively naive and ignorant to much of the knowledge this "Conscious" earth would have to begin with. Would you change drastically because of ants?

wat. i challenge you to find any object of mass similar to the earth, that has existed as long as the earth, that is not spherical. within the laws of physics that seem to hold in this section of the universe, what you're proposing is not possible. and the scales on which the earth changes and individuals members of species exist are so vastly different that the suggestion of any interaction between them is laughable. you don't even get appreciable global change in the length of time it takes a species to emerge and go extinct, in some cases. lay off the drugs, bro.

Please for the love of god write out your god damn arithmetic.
I think arc length would be better suited to this application. Assume the angle to be measured is a right angle and therefore 90degrees or (pi/2 Radians)
S=(pi/2)(3965)=an arclength of ~6228.2mi
But this is only 1/4 of the globe so we must now multiply our estimate by 4.
6228.2(4)~24,912.8 But again this accounts for the circumfernce of the earth. I do no know exactly which formula to use but I strongly believe you are using the wrong one.
n/a 435435435 2017-01-03
I am mostly using the 'earth curvature calculator' website, as my calculus is not what is used to be
n/a ButtRichard 2017-01-03
I didn't either I calculated that all in front of you.
n/a OffMyFaces 2017-01-03
You don't need a calculator and you don't need calculus. You just need very basic maths.
For curvature in inches and distance in miles it's just:
8 x distance2
n/a openlyincognito 2017-01-03
The truth appears to be they have no answer. It's just equation after equation of seemingly non sense. And when something doesn't fit add up or make sense, they just say, 'oh, you don't get it' or make up some new equation or math to 'prove' it. When they have no idea how it all actually works, just as none of us lowly pawns do, they get defensive because they suffer from cognitive dissonance rather than dig into it and challenge their beliefs. To me, there is simply to many intriguing points to ignore about our view of the earth and space. I don't think we have any clue to what the truth is and that's exactly what they want, complete confusion and two sides at odds and seemingly no way to prove it due to decades of misguiding the population.
Simple fact is the Earth's motion has never been detected, that's just one of many, many intriguing points, and if you can't even prove Earth's motion, how does any of it make sense? It doesn't. Kaku said if you are off by a factor of two in science it should be deemed wrong, he said we are off by 10 to a factor of 120 or something, the quote is something like that, I don't recall it exactly.
If we base the world view off observation, the globe makes little sense, just like you mentioned, the math that apparently is what they go by, but when it doesn't make sense based on observation, they just say, oh wait, that's because of this, that and the other thing. It's gets pretty funny after time to watch them get so defensive when all we should be doing is trying to find the truth together.
