so the line floats but you would do it over the water anyways

30 pound test and the 4 miles weighs say 10 pounds tops

No, even with high tension there is still sag

is it strong enough idk

Small, but not flat

Hm..is there a formula that could be used to calculate the amount of slack depending on distance, tension and material?

@jeremy think of a doable experiment

@Bannebie yes there is

it cant be optical since we know illusions take place have to be physical

something to prove the curve physically not by what we see

K so no lasers, and not flat objects.

yes 4 mile flat object

What's left

None exists

we cant make something ?

How

How do you make a flat surface

Esp that large

their is a spaceship orbiting earth with humans living on it we went safely to the moon and back

we cant make something straight and flat for 4 miles

I mean that's the limits of materials

i have no idea how to make a flat surface im not gonna lie

So this isn't a realistic method of proof

if u threw me in the woods and said make a flat surface

if i had tools i could make a flat surface

The problem isn't that it's flat, the problem that four miles is huge

i undestand

Largest surface plate from mitutoyo is 144 inches long

cant we make some superstrong lightweight material

a 3d printer ?

So you have an impossible bar here. Why did you not set this bar for the flat Earth claim

AAAAAAA

i dont believe flat earth either

PUSH MY FINGERS INTO MY EYES

besides the 4 mile straight flat object though i think them letting us explore antarctica freely would prove it

now u guys are gonna say we can explore antarctica at our own free will i know
