How do we know what's in the middle of the earth? No one's

Not a rock doctor, but I'm pretty sure you can estimate the density of layers of the earth via seismic refraction.

>inb4 someone posts scribbly seismic lines
>those prove nothing

well let's all move on then

It's possible that the people who live down there have a shield that renders them invisible to that type of detection.
Science is about seeing, not data, and until someone drills down there and SEES what it is, NOTHING is known.

I love this bait.

>>7844839
this

when a seismic shift occurs somewhere, you can measure the resulting waves of energy from triangulated positions, and this has become the standard because we have come to understand that the door is dense
the seismic activity is interrupted by a dense core, otherwise you would be able to measure the energy at an even spread all over the globe
but that's not what happens.. the strongest seismic activity occurs in positions in triangulated positions, inferring an object of interference

I hope you don't mean that.

I know you're a troll, but I love this subject of geology

this is how "scientists" would be fooled into thinking the earth wasn't hollow

>>7844859
Except it wouldn't.

There are also other ways the Earth is probed, like neutrino absorption measurements (these days it is even possible to detect the presence of the Moon by the absorption) and low frequency radio waves.

Not many geologists in here, right?

>>7844859
I'm going to believe this just for the hell of it. Nerds getting triggered are just a bonus.

I know you are an idiot

>Realistically, it could be hollow and have a bunch of dinosaurs living down there.
Yes. If gravity, biology and science in general are totally ignored, that is completely realistic

>>7846230
Those fields are null and void because they're based on the incorrect assumption that the earth is not hollow.

How do you know what's in the Middle East? You haven't been there, right? Realistically, it could be arabian nights and have a bunch of genies and rocs living there.

Are you retarded? If the earth was hollow then earthquakes would be impossible you stupid fuck.

>>7844830
Nobody knows, probably gnomes and shit building oils.

It could be the underground people fighting wars and dropping bombs on each other.

>>7844879
so how are we able to detect earthquakes on the other side of the earth? Where the vibrations go through the earth?

>>7847112
If you flick a hollow ball you can still feel the vibrations from the opposite side.
