You might want to try an earth curve calculator since you don't know the formula.

Earth Curve Calculator

According to the calculator, looking from ground level (0 feet) to an object 60 miles away, would result in 2,400 feet of the object being hidden, not 40 feet. Your calculation has us living on a slope, not a sphere.

(60^2 * 8)/12 = 2,400 feet

Try it out for yourself. That calc matches the earth curvature calculator, which in no way reflects reality.

Who ever made that up is completely stupid, the curve of the earth is not eye sight, it is 8 inches per mile of ground curve not your eye sight.

Could you give me an address or link to a thread?

I don't understand your point.

I was commenting on the fact that people in the northern hemisphere see one set of stars and people in the southern hemisphere see a different (consistent) set.

In the flat Earth model all people in the southern hemisphere are on the outer edge of enormous flat disk, but see the same stars.

It's been a while since I've seen looked at those arguments, but if I run across them again, I'll post it for you.

Yes the earth rotates east to west not north to south, our solar system is part of the Milky Way Galaxy that has billions of stars all around our solar system.

Not one of those mentioned the actual curve rate of 8 inch per mile, again line of human sight has nothing to do with the actual curvature of the earth.

Correction some did mentioned the curve at 8 inches, the only things those calculators are measuring is human sight prospective.

Edison Trent · Nov 10, 2017

True the higher one goes above the earth you will see more of the curve of earth, but. That does not mean the rate at which the earth actually curves at 8 inches per miles changes, those calculators will calculate a person's perspective if they travel that distance above the earth nothing more.

None of them are made by flat earth adherents to the best of my knowledge.

Just for reference, here's where you calc is insisting we live...

Haha funny picture, but 8 inches a mile curve is in direction, but at the North Pole and South Pole the curve is alittle less do to fact that our planet is not a true sphere it's called a oblate spheroid,

Your mistake is that you think every mile after the first will behave the same when being viewed on a ball. Sight has everything to do with the calculation when the problem pertains to viewing an object 60 miles away.

The only reason you get 8 inches in the first mile is because the 'miles' portion of the equation is 1, and 1 squared is still 1. The values escalate as the miles increase because the other numbers aren't the square of themselves.

The mistake you are making is all that viewing is just human prospective is what those calculators are doing, sight has nothing to do with the actual object shape, 3D art is just an example you can't see in this photo the picture is drawn on a flat surface, no matter how hard you try and think it's flat it looks 3D

Edison Trent · Nov 10, 2017

The same applies when looking at the horizon at ground level, it appears flat, because your mind cannot comprehend standing on a 3D ball earth and actually see the height, width, and circumference of the earth, so your eye sight will flatten out the horizon.

Umm, wow, ok. I guess I'll let you get back to your math homework. You should start with a tangent, and work up from there.

I knew you would come to your senses, and realize the earth is a sphere it only took a little 3D street to show you, you can't believe everything you see, your brain needs info of the height, width, circumference to actually know what your seeing is right. It's eye to mind perspective.

The formula is not squared, it is 8 inch curve per mile straight ahead every mile.

Say a tall building is 240 feet tall and it is viewed from a distance of 60 miles with no obstructions, the person can only see 200 feet of the building,

8x60=480 inches
480 = 40 feet

That woulsd explain my being able to see the Gateway arch in St. Louis from a hill by the Mississippi River, 50 miles south next to the town of Festus, but it doesn't sound correct in that the visibility should decrease faster than the distance increases because the further you go, the faster you descend... the first mile is is gradual, but the gradient descends faster further out.
I found the squared formulae online, but here is a new one I just found with a remark about the squared formulae at the bottom:

What about this? Does it look good to you?

What I have noticed with all these curve calculators are that they are figuring eye perspective not the actual curve rate of 8 inch a mile, that doesn't increase it is a steady 8 inch per mile, so in 10 miles there is 80 inch of curve over that length of the sphere earth, that would be 6'8" of curve arch over the whole length of 10 miles. If your on a hill and looking at the gateway arch, you would see more of the arch because your elevated and looking down at it, so the earth's curve will have less of a obstruction of view.

Please do.

You have to understand that this leaves me very dubious of your comment: "That's actually Flat Earth 101 stuff. If you don't know their answers to these things, you aren't educated enough in the debate for others to take such an opinion seriously."

I understand why we see the stars we do from the surface of the globe... what I don't understand is what you are trying to explain to me?

Honestly, I don't care what your suspicions might be. In matters like this, I don't make it a priority because I figure if someone really wants to educate themselves about a thing, they will take the initiative and do it, or at least attempt it. But if they don't, then it's not a priority to them, and therefore not a priority to me.

Agreed if person only asks negative questions and does no looking for answers themselves... I consider it a passive form of trolling.

Shemjaza · Nov 14, 2017

I asked for an explanation of physical phenomena which I have never seen consistently explained within the Flat Earth framework.

I'm happy to engage and examine the expansions or evidence.

Within the heliocentric model the Earth rotates around an axis slightly off perpendicular to plane of its orbit around the sun. This causes the appearance of the sun rising and setting and accounts for changed day length and seasons over the course of the year.

That's a simple 101 explanation for sunrise.

Let's have a conversation, without sarcasm and sneering.
