If it were the case that the Earth was a sphere what differences would you expect to see?

The equation confirmed by trig. The curve is .666 feet times the number of miles squared. I never ever see that. This would be 66.6 feet in just ten miles. Many lakes are that wide. Yet on a calm day I can lay down by the water and see the other side. No curve at all.

I became a Flat Earther when I saw Norfolk Harbor from 40 miles away. No 1200 foot curve existed. I saw the sailboats all the way down to touching the water all over the Chesapeake Bay. Not one was blocked by any curve and the water looked very flat. It was a very calm day. A very clear day. Very abnormal for around here.

Brief question where are you getting the 666 feet figure?

I use the equation A^2 + B^2 = C^2. It confirms 8 inches times miles squared. 8 inches is .666 feet.

Tilt of earth is 23.4 or 66.6 degrees. Speed of earth zooming around the sun 66.600 MPH. Yes a lot of 666 in the claims of a ball earth.

They never say 66.6 degrees because people are too smart to buy 666.

How do you utilize the equation exactly?

Also you said 666 feet times miles squared earlier

I use A = Radius. B = distance. The Square root is taken to get C then I subtract the radius to get the curve.

It is in miles so I multiply to get feet.

0.666 feet.

Should have added the 0 to make it more clear the decimal point.

0.667 if you round correctly

Or 0.666666666...

Isnt C = 2piR the circumference equation?

It is

Pi is not used.

It is just a triangle.

Why would you use a triangular calculation to calculate a curve?

Because it is easy way to confirm the 0.666666... feet per miles squared. I only did it a few times. It is something like 0.6661 or something like that. I just said 0.666 because that is a symbol and it is very close to it. I would never care about the thousandth I could be off in the calculation.

You know that that formula describes a parabola and not a circle?

lmao you used the Pythagorean theorem

Yes but I want a triangle not a circle.

I don't even know how that relates to the curvature of the earth

That parabolic equation is known to be false and using the proper (Sine) formula you can get it closer

If you assume the Earth is perfectly flat all that formula would give you is the distance between the point you're looking at and whatever distance you set as the radius

Or use a readymade calculator like this https://www.metabunk.org/curve/

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

So whatever point you were looking at compared to an unspecified point below you

don't know how this is mildly related to the curvature of the earth

You go down to the center of the earth. The radius it is called. You go out for however many miles it is. Use google earth or something to see. So two sides of a triangle at a right angle. Then C is the distance from the center of the earth up to meet the line of sight. That will give you the curvature you should see.

line of sight is not perpendicular

lol no you don't use the Pythagorean theorem to find the curvature of the earth

It would absolutely be. The curve would be below the line of sight.

h = r * (1 - cos a) is accurate for any distance

@mineyful Yes doing that would prove the earth is a ball. Don't do that. Is that what you are saying?

The Earth's radius (r) is 6371 km or 3959 miles, based on numbers from Wikipedia,
which gives a circumference (c)of c = 2 * π * r = 40 030 km

We wish to find the height (h) which is the drop in curvature over the distance (d)

Using the circumference we find that 1 kilometer has the angle
360° / 40 030 km = 0.009°. The angle (a) is then a = 0.009° * distance (d)

The derived formula h = r * (1 - cos a) is accurate for any distance (d)

Why should we not show that the earth is a sphere?

@mineyful Do you not understand almost no one would understand how calculus is used to get that formula. Few take college calculus. However most people in High School take math and would understand Pathagriums theory.

My son knows very little about math. But he knows that.

that's trig
