Yes, it's true, lucky you.  chuckle.gif
I thought FE was quaint too, when I first saw it in 2015. I figured it was some Amish rejection of modern science. Or a Luddite religious notion.
And then.
I looked at the math and physics and optics.

And now I can't believe how naive I was to ever accept the spinning ball in space vacuum. I grew up with sci-fan, read all the books from A.E. van Vogt on and was a Sci-Fi Book Club member. Now I see SF writers as brainstormers for the NWO. They make up bs and then it's put their propaganda in textbooks. Predictive programming.

I gave her a link to the math to calculates the curve properly, but she's stuck on a flat earther's bogus equation. Someone told me the flat earther's math is actually based on archaic surveying approximations.

Sorry about the poor quality image.
But . . . . .
My math is the same as your math.

Did you even read your link???

Here is your link.

Accurately calculate the curvature you are supposed to see on the ball Earth.

Distance:                                  Kilometers                                               Miles                             Calculate

Distance
1 mile0.0001
3 miles = 0.67 feet
2 miles0.00051 miles = 2.67 feet
5 miles0.00316 miles = 16.67 feet
10 miles0.01263 miles = 66.69 feet
20 miles0.05052 miles = 266.75 feet
50 miles0.31575 miles = 1667.17 feet
100 miles1.26296 miles = 6668.41 feet
200 miles5.05102 miles = 26669.37 feet

ONLY when you are measuring down from that horizontal line on your graph !

You ARE NOT walking/flying/driving/sailing out into space when you are FOLLOWING the curvature ARE YOU ? As you would be if you were to follow that horizontal line !

Tell us, what are the curvature readings FROM YOUR GRAPH once you get past the 3 o'clock position on that graph ?

Correct. The math will not work after a while. You will be entering negative territory.

So what is your point?

There are many online algorithms to measure earth curvature.

This one lets you plug in observer height, target height, and distance to determine how much bulge there should be.

blink.gif You are STILL measuring from the horizontal line up in the sky ! You are measuring DROP OFF by doing that !
If I asked you to measure a beach ball, would you draw a straight line above it and measure down to the surface in a hundred places and then find a math solution or would you wrap a tape measure around it ??

I am not, repeat NOT, measuring the curve on a beach ball.

I am measuring the drop from sight. Which is a straight line.
Why are you belaboring the point?

Can a 1450-ft. tall building be seen from 50 miles away?
8 x (50x50) =  20,000 inches ÷ 12 = 1666.666 ft.

No!
is the answer. Risky Rob's link corroborates that figure.

Yet Chicago's  Willis Tower is clearly visible from across Lake Michigan.
Conclusion: there is no ball.

''I am measuring the drop from sight. Which is a straight line.''

NO, you are NOT ! From eye height, about 5 foot, you are looking DOWN at the horizon line !!!!!!!!!!!!!!

It boggles the mind why grav can't understand that crucial point you just made.

OK, y'all are right and the whole world that measures drop from sight is wrong.
Observer height is always included in the calculation. Always. In some cases photographers place their cameras a few inches above the ground or water.

By the way, the horizon is an optical illusion, which is another thing the AK will dispute. In optics, all lines of convergence meet at the vanishing point. When zoom lenses are applied, the vanishing point moves further away.

My last post about what is common knowledge.
Since no one will address if Chicago should be visible or not from 50 miles.
Which is the main point. Which - why is everyone avoiding it by quibbling over a non sequitur?

All your counter points contain non sequitur, CGI and optical illusion - what's there to quibble over?

Hmmmm, 50 miles at 8 inches per mile is 400 inches. 200 inches the camera side of the horizon and 200 inches the buildings side of the horizon (as the horizon is at the halfway point)  So, the lower 16.5 FEET of those buildings will be hidden from view from 50 miles away AND ONLY IF THE CAMERA IS AT THE WATER LEVEL !  NOT up on the bank and taken at eye height as that photo of yours was !  Show the un cropped photo YOU DO HAVE that shows the vegetation AND the water level at least 6 or 7 feet below the camera !

Get on a plane and fly to the edge with camera in hand.
Prove it.

Anyone?

Let's see it.
