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

we stil dont know

!!

"reeeeee"

So this is fake?

This is basically what caused Isaac Newton to drop his right club banger @Toastlawine

. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. ... So, scientists study the path and speed of these waves through the earth to decipher boundaries and the materials that make up the layers.

People knew things would fall to the ground

But Isaac newton wanted to know why

By looking at the time of arrival of the main set of waves, and how the frequencies of the waves are arranged within the set, scientists can learn about the density and other properties of the layers. The relative differences in arrival times of the S and P seismic waves at several recording stations tell scientists about the different speeds those waves were traveling at, which in turn gives information about the density of the material the layer is made of, and how thick the layer is in several directions.
