gravity is the curvature of space-time

light gets affected by gravity and it has no mass

Also, to further AstralSentient's point, we know Eratosthenes calculated the Earth's Circumference in 100BCE and was only 66km / 0.16% away from the currently accepted polar circumference

ok what makes objects fall to earth in the globe model its mass attracting mass due to mass

How about, sh*t falls (in a predictable relationship), no theory or explanation needed.

ok but thats not the globe model though

in the globe model objects fall down because mass attracts mass to mass its why the moon orbits earth and the earth orbits the sun its how all the bodies in outerspace were formed. i would say mass attracting mass is critical to the globe model thats all

I don't depend on models, those are abstract, idea based.

eratosthenes calculated the circumfrence then chris colombus goes 2500 miles and thinks he almost circled earth i doubt it

no proof of eratosthenes

plus everyone knows 2 wells or 2 sticks int he ground would work with a flat local sun and a sphere earth with a far sun

Too bad 'flat local sun' is based on nonsensical unverified theory and fails to match reality.

so how did he prove the circumfrence if it would work with a flat earth and local sun

Oh, you brought up models of the flat Earth, wonderful

I just want to know how they manage to break physics

It wouldn't

You know, having a light source projecting through the same fluid, yet not to the same distance

neil degrasse tyson said erathosthenes experiment would work on a flat earth with a local sun u should bring it up with him

He said it wouldn't

he said it would

And that magical straight line down the middle that is the divider between day and night

Nope, he said it doesn't

he absolutely said eratosthenes experiment would work with a flat earth

u didnt watch the video then

Lol

he said it wouldnt work with 3 sticks or 3 wells

Oh,

eratosthenes didnt use 3 wells though

So you admit he did

he said 2 wells or sticks works on sphere or flat earth

But not 3

So it fails altogether

eratosthenes didnt use 3

If he did use 3, the flat earth couldn't explain it is the point

maybe

but he didnt

so now we debunked eratosthenes

So? It doesn't depend on whether he used 3, just that using 3 disproves flat earth

what is next

it doesnt disprove we dont know 3 would or wouldnt work

Uh, yes we do
