Spheres have centerpoints.

Earth has never been described as an ellipsoid, its roughly spherical with a small amount of deviation at the equator. Even so, both ellipses and spheroids have center points.

A mechanical pulling force? Its literally the basis of the pulley, which has been used for thousands of years, you can easily measure it and its done in every physics 101 class.

Give me an example of a unit of "volumetric mass density". If I can use any unit I'll just use chickens per martian dog bone.

try to learn your model before you defend it

a pully does not have a pulling force, you push the rope towards yourself or the ground
its only described as pull rhetorically, there is no pulling force
please go back to highschool

An Earth ellipsoid is a mathematical figure approximating the Earth's form, used as a reference frame for computations in geodesy, astronomy, and the geosciences. Various different ellipsoids have been used as approximations.

In other words it's a convenient model not a description of the Earth's shape, please read your own sources before you defend it

Wicca-pedi says "The Earth has a rather slight equatorial bulge: it is about 43 km (27 mi) wider at the equator than pole-to-pole"

Describing a 27 mile bulge as simply due to "convenience" is actually a Flat Earth point that your model is basically just a mathematical abstraction you mistake for real.

Your doing great at proving the Flat Earth, nice job.

Let go of the pulley and see what happens to your package. The fact that you have to expend energy to move against gravity means it is a mechanical force in the opposite direction

Let's say you want to "pull" a drawer open - you need to put your fingers on the inside of the handle and "push" it towards you.
Claiming pull was involved is a simple rhetorical reference to keep you uneducated about actual physics.
I see why this topic triggers so many, it really exposes who the uneducated are.

So things you've run away from just today include that gravity does mechanical work, that you don't understand thermodynamics, and that gas is perfectly capable of having a border without a physical barrier

When you let go of the drawer it does not slam shut , when you stop pushing against gravity it pulls you back to the ground. Point the drawer up and pull on it and then let go and you'll see that the drawer now slams shut
