as one leg is longer then the other you always walk in circles

ok then use a plane

They do

10000 miles straight lines

@da multicoloured lizard take a globe model, like the ones in school, and but some rope around 2 points, any points. is that a straight line or a semi circle?

ofcourse its not a perfectly straight line - because youre walking around the curve

so your test is inconclusive and anyway cant be done with walking

it can be done with walking and swimming but it takes ages and you will have to have incredible strength to do it

so i cant actually do it, it is more of a thought experiment, right?

how about an actual test that i could do?

its not a though experiment, i just dont have a plane

cmmon lol, proving a globe shoudnt be that hard, right?

all i ask for is a test i could do myself. like actually do. is there such a test?

One of the best documented methods for determining the Earth's roundness was first performed (to our knowledge) by the ancient Greeks. This was achieved by comparing the shadows of sticks in different locations. When the sun was directly overhead in one place, the stick there cast no shadow. At the same time in a city around 500 miles north, the stick there did cast a shadow.

If the Earth were flat then both sticks should show the same shadow (or lack of) because they would be positioned at the same angle towards the sun. The ancient Greeks found the shadows were different because the Earth was curved and so the sticks were at different angles. They then used the difference in these angles to calculate the circumference of the Earth. They managed to get it to within 10% of the true value – not bad for around 250 B.C.

Another piece of evidence for a globe is the difference between the night skies in the northern and southern hemispheres. The view is completely different because the Earth beneath you is pointing in a different direction. If the Earth were flat, the view should be the same. This can be made even easier by simply comparing when it is night and day in each country.

You can observe the planets as well. They all rotate, and watching over the course of a few days gives a clear picture they are spherical rather than flat. The chance that most of the planets are spherical but the Earth is flat seems very unlikely.

ok, can you name the greek guy that did that test without wiki? just curious

no because i dont have complete knowledge of the last 2250 years

are you gonna try and disprove me because i dont know the exact name of a philosopher

Eratosthenes

no lol

ok, great

i will only point out that according to NDY that test also works just fine on a flat earth and with a close local sun

(neil degrasse tyson(

so i guess the question then becomes: how do we know if the sun is small and local or big and far away

hes given proof the earth is round, if u believe that, u should believe other stuff he said

no, he just said its round lol saying aint the same as proving

but once again, how can we tell if the sun is small and local or big and far away? how can we test for that?

if it is small and local, we would be able to fly a drone up to it

well not if its 5000 miles up

thats still local btw

so why isnt all of earth lit up?

well the sun could still project light like a normal torch does, right? a torch on a wall would still only project light in a small circle on a wall and not on the entire wall...

maybe there is another way

so all ur doing is making assumptions yet complain when i dont have evidence straight away? the level of hypocrisy is unreal

no im saying there must be a clearer test for that

an easy observation maybe

my torch is not as bright as the sun, yet during the night i can see the rays travelling through the sky. so why cant we see the rays of the sun coming down during the night?

well we do know the atmosphere bends light. so at night when the sun is further away from us, the atmosphere could block us from seeing it at all because the very dim light would be bent away

prove it bends light

ohboy

difraction?
