they have to be divergent in order to originate from a point sun and reach two wells

that little ms paint drawing you made

you only pretend they aren't when you pretend the sun's rays are entirely parallel

ye

that would cause divergent rays too

it would affect the divergence is more what i should say

all rays that aren't from an infinite sun and parallel, are divergent

also i couldd see your point that, if you can say they're roughly parallel

https://kpharri.wordpress.com/2013/02/05/the-suns-rays-are-parallel/

then you could say their divergence could be roughly unaffected at one point

that's fine, until the fact that the wells are separated

so it's different portions of atmosphere, each which can refract differently

so the result is still unpredictable

yeah, that link is pretending that the sun's rays are parallel

like, you can see from his diagrams that they aren't

but that, you know, close enough

but ye if we're being honest about the physics

the issue is that the rays will travel through 2 different parts of the atmosphere

so parallel or not, they'll get refracted differently just bc it's 2 separate bits of atmosphere

and that can affect divergence and everything else and put it all out of whack

i.e. in terms of the well, light above one well gets bent at another angle than at the other one. and experiment broken

ye eratosthenes was a good start, but now modern science and technology provide better and more accurate experiments to prove the earth is round

it's because of these points we don't use sticks to prove the earth is round

yeahh that makes sense

but the modern proofs have become so inaccessible

that it's actually possible to question if they're legitimate

butyeah we can agree on the sticks at least

why is it inaccessible

@raspberry ^

@Alexandre like, cavendish is the main one

so, we're supposed to be able to see two iron balls attract

except then nope...gravity's too weak, you have to do it in a restricted setting in a university or govt lab

What about foccault's pendulum

The Earth is not round or flat, it's a cube

@GreenPixel it's an interesting approach but funnily enough i've heard the same thing about that

from globe earthers at least, that it's too small and sensitive to friction to carry out

i feel like things along these lines are worth testing though

Its definitely hard to achieve on one's own, but it is much more publicly accessible and visible that cavendish I think

There are several large ones around the world that are open to visitors

Although there's always the motor argument

it does feel more approachable. for looking for/disproving the earth's rotation i feel like something similar could work
