Agreed

i got a 6 foot one and my pool isbeing opened on the 30tth so ill take a pic of the flat water then

30km spirit level over water, show me gaps either end, flip it upside down to prove the spirit level isn't warped, rotate 90 degrees repeat, yeah I'll concede a globe

30km is too much lol just 3 miles is enough

2 miles is enough i think

You and I bot know a 3 mile or 5km level would give inconclusive results

HAHAHA

well 3 miles should be a huge gape

gap

I hiked 40km last year

near 3 mile island it would surely be a twisted result 😄

in 3 days

ok

idc lol

8 inches per mile squared over 3 miles is

whats your point @PsyClone

Stop using that cointelpro measurement right now

or are you just flexing

?

No i am not

u think its more ?

whats cointelpro

The globe model does not conform ot a parabolic y = 8x^2

the curve should be more than 8 inches ?

it's wrong, stop using it

h = r * (1 - cos a)

im not good with math

over 3 miles how much do u think the globe should curve ?

r = 6,371,000
a = d / (40,070 / 360) in degrees

so h = 6,371,000 * (1 - cos(a))

So d = 4827

big maths

a = 4827 / (40,070/360)

a = 4827/ 111,306

a = 0.0415 degrees

h = 6,371,000 * (1-cos(0.0415)

h = 6,371,000 * (1 - 0.9999997367)

h = 6,371,000 * 0.0000002632

h = 1.67684 meters

Yeah what sheeple said, because i suck at maths
