light bends, use something that doesnt or we can atleast control how much it bends

if it is same length then they have no argument, if it doesnt reach then you dont have an argument

im an observer, dont believe either one i want to see someone actually using his head in avoiding a "conflict" to their results

everyone is going "i dont believe what you guys say or show" and "you dont know what ur talking about (vague reason #52) is the reason why ur wrong"

someone make it happen, a thread or something that wouldnt put strain on the poles is better i guess

It's not that easy. The formula to compute the difference (delta s) of the length (s) of the rope at the bottom and at the top (h) of the sticks is:

delta s = s * h / R

where R is the radius of the earth. On a distance of 5 km and a stick height of 1 m you get on the globe a difference of the rope length of 0.78 mm. It is impossible to measure this difference with a 5 km long rope because there are no ropes that are stiff enough.

But there is a simpler way to get the shape of the earth.

How far is the distance from the north pole to the equator? e = 10008 km.
How do we compute the circumference of the equator on the flat earth and on the globe?

FE: U = 2 * e * pi = 2 * 10008 km * 3.14159 = 62882 km
GE: U = 2 * R * pi = 2 * 6371 km * 3.14159 = 40030 km

How big is the measured circumference of the earth? 40030 km!

So I come to the conclusion that the earth is a globe!
