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

It needs predictive power

And has to agree with all evidence presented OR be the most comprehensive model avaliable

@Sassy Undeniably satisfactory?

Use the scientific definition, please

Not the first one you find in a dictionary

I asked you what the word model meant. I did not say scientific model and neither did you so go figure

A scientific model is a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes. Scientists seek to identify and understand patterns in our world by drawing on their scientific knowledge to offer explanations that enable the patterns to be predicted.

You knew exactly what I ment

No be clear when you speak young man

There we go

That is the definition

Now

You believe it is electrical discharges, no?

So read it carefully it is a conceptual representation of a system of ideas, events or processes. So they don't know they just offer explanations

What evidence do you have for this model?
