why do folks still think the earth is a globe when basic math disproves it (and 200 other things)

Question

here is something i figured out on my own using strings and balls and basic math...but when i try to post it on craigslist to see if anyone is interested in discussing it with me..it gets immediately removed...

if anyone on this site is serious...cares about facts/truth...and wants to email me to discuss this...i welcome that...

every circle has the same "curvature" 

and you can test this out on any sized ball you have...it's the same...it's one of those extra long numbers with lots of digits after the decimal point..like pi...maybe not as long as that but idk...anyways:

if you walk from the pole to the equator (6,225.25 miles, or one quarter of the circumference), the "drop" (on the imaginary axis) is exactly the radius (3,959 miles)

so for every 1.57 miles travelled along the surface, there SHOULD BE a "drop" of a WHOLE MILE

(and we know no such drop exists)

no matter what sized sphere you are working with, if it is a sphere, you will get that 1.57 to 1 ratio

or you could say it another way:

 

there should be (but isn't in reality on this flat earth) about 0.64 miles of drop for every mile along the surface of any sphere...and if there isn't, it is NOT a sphere.

here are some more calculations:

6225.25 to complete 90 degrees

so 69.169444444444444 miles to complete one degree

 

times 360 degrees equals 24901

if you’ve travelled 90 degrees (on the sphere with a circumference of 24901), you’ve dropped 3959 miles down the axis

and you do that 4 times in all to complete the circle

3959 times 4 is 15,836 MILES (of movement along that axis to complete the trip around the globe)

24,901 divided by 15,836 is 1.57

and the “drop” is the SAME over EVERY MILE…it isn’t more flat in the beginning and way steeper/more curvy later…it’s equal…or it is not a circle….

15,836 divided by 360 is 43.988888888888889

so for every 69.2 miles to complete one degree of the circle, there should be a drop of 44 miles

Answer 1

This makes absolutely no sense.... It might be easier to start with the established principles, and post your analysis of why they might be wrong.

For example, do you agree with Newton's Laws (and their derivatives)? for example, suppose the earth were a flat disk---do you know what would be the gravitational force trying to pull it together into a ball?

email discussion?---I don't think Wyzant rules allow that. You can always hire a tutor and have the debate "on the clock".

Addendum 01/23: Humans have always defined UP and DOWN in terms of the direction that objects move when dropped or thrown in some direction. Those movements are influenced by the force of gravity (See also the comments about Newton's Laws.....)

Craigslist.....!!!???---I thought that was for buying and selling....

UPDATE:

On the spherical earth, down is defined as moving towards the center (where the center of gravity is). If you travel along the curved surface, the definition of "down"depends on your frame of reference. Suppose we define "down" to mean "going below the plane of rotation---namely the equator. Now the curves make sense---if you start at an arbitrary point and travel due south, you are going "below" the plane of rotation. there is also a horizontal component of your velocity that is in the plane of the equator. some pictures will make all this clear.....
