Why does the Earth and its surface move in such a way that could create normal force they is more ore less equal anywhere you stand? Why does nobody else see a problem with ignoring that?
This is high school physics not a mystery.
Gravity on earth results in an acceleration of 9.8 m/s^2 towards the center of the earth. That result in a downwarad force that in my case is about 180 lbs. As you have probably noticed we are not in the center of the earth. The reason I do not move to the center of the earth there must be a force that equals my 180 lb force in the opposite direction, that is the normal force. Where does this mysterious force come from? When I stand on a piece of steel for instance my weight causes the steel to slightly compress by deforming the molecular bonds, the resistance to the deformation of the bonds is a force agains my feet. The steel or whatever material will compress until it matches the force pushing against it. If the force is too much for the material the material will break.
The normal force is not just about gravity. Push against a wall. In other words put a force against the wall. Do you go through the wall? If not then the wall must be pushing against you at the same force as you are pushing against the wall, this is the normal force. Suspend a board between 2 saw horses, put a wieght on a board and the board will bend a certain amount. The weight does not move after the initial deflection because the board is developing a normal force in the opposite direction of the force of gravity. The stressed bonds can easily be seen by the deflection of the board. Increase the weight on the board and the board will deflect farther until the normal force equals the weight.
When you throw something "up" in the air, all of the acceleration happens before the ball leaves your hand. From that point on, what you witness as the ball "going" up in the air is the ball moving slower than the Earth in the opposite direction you threw it. However, the ball is NOT moving any slower in the direction perpendicular to your throw and the Earth isn't moving in a straight line away from the direction you threw it, so the ball collides with the Earth again. It collides in roughly the same spot it was thrown from because it still has the same speed as that spot in all directions except "up". Actually, the ball has a greater speed in one of those directions because you're actually throwing the ball in a diagonal vector away from the surface which is not completely against any of the major directions the Earth is moving in. The ball will come back down even without gravity.
I am presuming that you accept the fact that that would happen on all places on the Earth's surface - so even if everyone on the planet threw a ball upwards at the same time they would all see the same behavior (i.e. a return to Earth.)
Given that, how can the Earth be moving towards all the balls that are in the air at the same time? Do you claim the Earth is constantly expanding to "catch up" with the ball?
Because depending upon where you are on the surface, you can only throw the ball "up" in a direction that is away from the center.
"Up" is relative to where you are, it is "down" on the other side of the Earth.
Correct. And thus the Earth must be moving away from its own center, in all directions, constantly, for your claim that "the Earth moves to meet the ball" to be valid. No amount of mathematical jiggering will allow you to avoid that basic principle.
Correct. So the balls on the "down" side of the planet would go flying away.
if that were the case the rotation of the earth would throw us off the planet like rain drops on a spinning basketball
jiveabillion you are really and truly not making any logical sense. It is not that we do not understand what you are saying - it is that we can not believe you are saying it because it is complete illogical nonsense. There is no need for me to reply since your mind seems to be made up and no amount of counter evidence seems to make any difference. I will check back in after your talk with the physicist. I fear you will simply believe that he can't understand you either when he tells you your ideas are wrong.
It's impossible that either tensors or fields to make sense to you in light of what you've already said. Further, even if you did understand it, it completely contradicts what you've said here.I'm willing to accept tensor field theory, it makes sense to me.
We don't need anything more than general relativity to explain gravity (as it applies here) certainly not the random ideas you have offered. None of them have anything to do with the causes of gravity.What I am saying is that if we have curvature of space-time and inertia and the momentum from the movement I described, we don't need mass attraction to explain gravity.
In general relativity "the movement of the earth" is not in Euclidean space. You are giving us nutty "causes" which are all in Euclidean space (your vector calculations for example). You can't get there from here.You might ask, "What about the Cavendish Experiment that showed mass attraction between two non-moving objects?". The Cavendish Experiment can be explained with tensor fields and the movement of the Earth.
That's absurd.My issue with that experiment is that it was done on a non-inertial frame.
Not quite. However that statement proves that you aren't sure what the term means. The pendulum us simply a device that responds to both gravity and the rotation of Earth.Foucoult proved that the surface of the Earth is a non-inertial frame.
If what you were saying were even remotely true, then a person's weight at the poles would be substantially different at the equator which of course is not correct.You have a constant movement around a sphere that will cause a very small, but measurable amount of acceleration. Then you have the tension on the surface and structure of whatever you are suspending the lead balls from. Whichever small ball is closest to one of the tensor fields caused by the larger ball will move towards it at a rate dictated by the constant acceleration of the Earth's rotation and the inertia of each ball. It basically only measures the inertia of a known measurement of mass. Of course that information is useful for estimating the gravity of a planet, it's pretty much the same thing, but it doesn't mean that mass is actually attracted to other mass.
According to your beliefs, there is no interaction between a body above its surface. Therefore this whole premise contradicts your main idea.Even the GRAIL gravity maps could be explained this way. Anything that causes pressure between the surface of the Earth and a satellite will cause variations in the "gravitational field". It could be radiation pressure, since radiation is absorbed by more dense material and reflected by less dense material, it could create a measurement just like what they map with the GRAIL satellites.
If that were even remotely true all of orbital mechanics would have been wrong, Newton would be unknown, and you would be basking in the praise heaped on Newton, for having finally explained these strange orbits, which would be entirely different than the ones that actually occur.Hell, that could even explain the eccentricity of orbits if both the center of the Galaxy and the Sun are "competing" forces where the planets both reflect the radiation pressure and block it from pushing other planets and moons towards and away when they get between another planet or moon and the center of the galaxy or the Sun. That would be interesting.
The Earth doesn't just move to meet the ball, the ball also moves to meet the Earth.
Have you even looked at a model of the Earth since you started contributing to this thread?
It doesn't matter where you throw it from, the Earth does not move in exactly the opposite direction on the same vector of your throw.
No no no. Why would they go flying away? They have momentum to stay with the Earth.
Do things go flying out of your hand when you're traveling at a steady speed in a car? NO.
If you toss a ball up in moving car, does it come right back down? YES.
Why? Basic Netwonian mechanics says that once something is in motion it tends to stay in motion (same direction, same speed) unless another force acts on it. So if you throw it away from the Earth it keeps moving away from the Earth unless another force acts on it. What is the other force?
Yes.
Right. For your system to work the Earth would have to move in roughly the same vector of your throw. It does not.
No, you have just given it momentum away from Earth by throwing it.
Correct. They stay there, due to the product of friction and the normal force provided by gravity. Remove gravity and the object would slowly float away since the Earth spins. Of course the car would float away too, so you'd have to postulate a car on rails or something. The only way to avoid this would be to drive the car at ~1000mph directly west to exactly oppose the spin of the Earth.
Yes, due to gravity which overwhelms all other forces by several orders of magnitude. I thought you didn't believe in gravity though.

Just forget it. You obviously can't keep track of 2 things moving relative to each other in your head. If you would, you would see that an object thrown would impact the Earth again as their paths intersect.
Edit: It isn't gravity that overcomes anything. It's the momentum the object still has in the direction that is, at the time of impact, towards the center of the Earth.
If something falls from 100 meters and takes 4.51 seconds where is the point where it lands 4.51 seconds from the time it started to fall?
Right. But you postulate a thrown object whose direction is AWAY from the center of the Earth. What changes it?
