Flat Earth Theory / Re: FE Gravity

Can someone explain how the sun and moon revloves in flat earth model (I saw it on the faq but dont really get it). What forces are causing the sun and the moon to move like that, there is nothing in the center so there is no centripital force pulling it

I am sorry that sound confusing, what I mean was that when the mass of the body is the same, the force of gravity act on them equally, and the force is proportional to the weight. If the object has more mass then, the total force that act on the object is higher compare to the one with lower mass, this doesnt change the fact that gravity act on object equally. Imagin putting 1 kg weight on a scale and 2 1 kg weight on the scale. The scale will show more weight on the one with 2 1 kg weight. If you were to drop all of them at the same time, the acceleration of all of them will be equal, if you merge all of them together doesnt change the total force acting on it or the total mass. And you will get the same acceleration if you use the formular F=ma

I think you are misunderstanding inertial resistant, inertial resistant is the object trying to stay at a constant velocity, when gravity acts on a body of the same mass, they will have same inertial resistant, if an object is made up of more atom or atoms of higher molar mass then the inertial force is higher the reason why they fall with the same acceleration is because gravity does not apply a constant force on the object as a whole, but it act on every matter that made up the object ( proton, nuetron,electron) and gave them force proportional to their mass .And inertia is not related to the weight of the body. And what you see on a scale when you weight the body is not the inertial force, its the normal force which was cause by gravity pulling the body to the surface and the surface is pushing back at the same force. The body that consist of more matter will have more weight because gravity act more on it as a whole.

How does gravity pull object down to the earth at the same rate and ignore the fact that bodies have different inertial resistences to being moved through space?

It's easier to roll a marble versus a bowling ball, for example. All bodies exhibit internal resistences when they are moved through space.
So what you dont understand is why objects of different mass have the same acceleration under gravity. The thing is gravity acts on an atomic level which means it pulls every atom down towards the center of the earth, every atom in the object gets acted on by gravity equally. This is why the difference in mass does not effect the acceleration due to gtavity. To put it simply, (if air resistance is negligble) if you drop an 2 object of equal mass of lets say 1 kg, they would fall with the same acceleration,  now if you have 3 object of mass 1 kg and drop them all at the same time, again they would all fall with the same acceleration. Now if merge 10 of the 1 kg mass together, they would fall with the same acceleration as the 1 kg mass because all 10 of the 1 kg mass gets the same acceleration.  In terms of math, (acceleration due to gravity is 10 to keep it simple) if you drop a 1 kg mass using F=M A  F=1×10  F=10 so the weight is 10N for every kg, if the mass is 10kg F=10×10 = 100N, the weight is 100N, which is equal to the weight of 10 1kg weight. Hence I claim that gravity act on every object equally.

this brings up an important point...

Why does the universal force act in different amounts on different objects?  If I drop a 1kg and a 10kg ball off the ground. They are both falling towards the earth. So clearly the universal force is not acting on them but is acting on the earth. But if I dig its not acting on the earth underneath me. is there a big metal plate at the bottom of the earth that the universal force acts on?

it also seems to act on random satellites, the moon, the sun, and they seem to accelerate the same amount. Are all objects in the universe that accelerate equally massive? When an asteroid hits the earth, does the force automatically increase to maintain the constant acceleration? How is it regulated?

The more I think about it the more confusing it gets? is all of nutonian physics wrong?
