Do you think there is one? I don't like believing in things that aren't supported by math and/or intensive observation, so I don't
does anyone have any info on concave earth?
never heard of it til now
I dunno

@Alexxx come here
yeah ok
it is the right thread this one
ok... draw a straight line on a flat earth model and try to get back to your starting point
watch it
no name calling
no ad homs
see rules at the top
if i by a straight line you mean for me to head east and keep the same distance to the north pole, i can do that. its the same on a globe model (except the equator) where all straight lines are actually circles
thin ice <@!356085459186614273> cool it
what you ask for cant be done except north south on a flat earth
stick to the topics
but how is that conclusive? it is the same issue on a globe model also
no
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.
