So I was in the shower today...

[Agamemnus]

You'd still have a pull to one side, but the opposite side is also pulling on you just as much; that's why you wouldn't move, not because there is "low" gravity.

What's your point? You're just proving what I've been saying. The effect of the forces cancelling out is low gravity.

Forces cancelling out doesn't equal low gravity. Let me state this one more time. The reason you don't feel anything at the center is because you are being pulled by gravity, but from all sides.

You're hopeless. What do you define low gravity as then? THERE IS LOW GRAVITY because if you measured the gravity effect on particles, it would be LOW..

You don't add up the forces because of the reasons I mentioned and I'll mention some more, too: friction, the permeability of matter, magnetism. If you hit a ball with force X, which is moving at force Y, and that ball hits you afterwards, the total force is not force X + force Y. Don't lecture me about learning concepts either.

I'm just trying to help here. Do you want or not want to learn why there is pressure at the center?

No, I don't want to learn why I am wrong, because I am right.

So? The force will be small at the center because gravity will be low. Just because everything forces towards everything "below" it doesn't mean that you can somehow add up the forces. You're going to lose a lot of that force from simply the density of matter that stops the force, from magnetism, and also from the much smaller force in the center and near the center.

You don't just "lose" force. It has to go somewhere.

Newton's 3rd law: For every action there is an equal and opposite reaction.

That's just a vocabulary identity. Yes, you do lose force, from the total force of gravity on an arbitrary sphere of matter in the center on those items. There is no law that says "force is transferred with 100% efficiency between one particle to another".

If the density of the matter is blocking the force, then it is also pushing back on the force. This is what creates the pressure. Gravity pulls on the matter, the matter has nowhere to go, so it pushes back on itself. Now you might reply "but since there is low gravity at the center, then it's not pushing back on itself as much." But remember, there is gravity at the center, lots of it. But it's not really the center that creates the pressure. Consider the crust of the earth. With it being that high, which direction do you think it is being pulled? Downward I would hope. This massive amount of matter is pushing down, so is the mantel. Now even if there was 0 gravity at the center, what difference is that going to make? There's still a massive amount of matter pushing towards the center. This will definately create some pressure.

That pressure will be created at that point where it is "pushing back" (not really pushing back), not at this arbitrary sphere farther "down".

I never said there was NO pressure, either. (I think)
