diging down is a way to know what is down there

and that surprised those who did it

Wym it doesn’t verify anything? That’s like saying you can’t know that water has a different density from air solely because it refracts light

Idk if I’d say it surprised anyone. We knew it’d get hot and the logistics would get increasingly more and more strained

i know its hard for you to grasp the fact that people make stuff up for money

Nonargument

or other reasons

@RadRhys we aren't propagating earthquakes although some think the HARP machine causes some of them do to it's use. Rough origins of earthquakes is not knowing where they come from what causes them and what they do other then the destruction they cause to our man made structures so what you have said is we really don't know anything at all about them. Carry on

what about all the water they found

Which body?

I don’t care about cause rn, that’s not within the bounds of the discussion. We’re specifically looking at why we can detect P waves going back to the surface.
And yes, knowing the origin is literally knowing where they come from.

one problem here is some are thinking earth is a flat disk

we don't what is underneath

what if it looks more like this?

i.e. large mass of known shape/size under the flat surface

thats just another story @Flat Earth PhD

Now we’re getting into Occam’s Razor. What’s more likely, an untestable mirror of sorts that would reflect P waves and change their speed, or P waves traveling through the Earth?

stories are not evidence

true but the point is we can't assume we know anything about the shape

under the surface

if you know nothing about something say nothing

That’s not an argument

That’s not even a defense

@Flat Earth PhD did you run the moon test with a photovoltaic cell yet?

I gotta go now, I’m done eating and this is my vacation

@RadRhys you don't know where they come from it is just an educated guess. They measure the strength of them when they occur but that doesn't tell you the what, the why, or how to prevent them. SO you know nothing other then their best educated guess which hasn't change in umpteen years. Don't bring up ridiculousness then. Yes it is okay when you get schooled on your own model to retract and refrain from using it as a defense and you can simply concede a point by saying you don't know something. We do it all the time. Give it a try.

@Sassy Undeniably it has changed

Quite recently, in fact

To explain the phenomena we see

What parts of it.

Plate Tectonic theory appeared in the 50s

Was only actively adopted in the 70s

Yeah Theory means you don' know and so you have a best educated guess so it is not a fact like I said

No

Theory means model

what is a model?

I know we just going to break down the word soup

Scientific terminology is not the same as colloquial speach

What is a Model definition please

A model is an explaination which describes why we see the phenomena we do
