Hm

One I've seen talk about recently is electromagnetism

Well I would actually think: As long as the flat earth doesn't work in my head I shouldn't believe it is flat. But the thing is that it just has to be since I've never seen any curvature. I spoke to people and they say I have to go higher up but I can't see it on a mountain either...

why does "gravity" matter?

things fall down at 9.8m/s^2

so what

But there has to be a reason for that right?

but so what? more than likely you and I aren't going to confirm it.

And it doesn't work the wayy you learn it at school on a flat earth

it's irrelevant w.r.t Earth's shape

why not?

nobody says it's a thin disk

we don't know what is underneath

because you are pulled towards the center and someone standing eg in Australia would stand at an high angle

no

we have no clue what the mass distribution is

under the surface

so you cannot make any predictions.

right.

so forget about it

funny how we used the nuke tests to probe the earth's content

worry about the things we CAN see and measure

we've only drilled 8miles

p and s waves were doing some funky things

irrelevant

around the world p and s waves from these blasts keep chaning velocities at the same depth

focus on finding/measuring curvature

we were able to keep detecting these changes in velocity

and there were several places where we observed this

fun stuff

angles of them bouncing off were really interesting too

let me see if I can find some diagrams

irrelevant

assumptions on top of assumptions

direct observations from measurements just because it doesn't agree with you doesn't mean you can throw it away

we have no clue what is under the surface

yes. bcs it assumes you know what is underneath

and we don't

lol we didn't

it wasn't until like the 60's we knew

that's the point
