>>18643547>You can describe pressure by the movement of particles
No you can't. Pressure is force over area. In a planet with no liquid mantle, solid all the way through, there is a great deal of pressure, but no movement.
Pressure is a rather fundamental concept that you don't seem to understand very well. Like force, acceleration, gravity, and so on. School children should understand these things.>We're talking about two different approaches to explain the world
We're talking about two different models. One model explains the world, and all observations. The other fails miserably and isn't even an internally consistent model.>you can't determine the radius of a flat plane.
My local pizza place sells pizzas by the radius of the flat plane, 14", 16", and 20". If you mean depth (again another simply concept you should be able to understand), yes, that's measurable too.
