The Mechanism of Falling Object: no gravity

AI Thread Summary
The discussion centers on the mechanics of falling objects and challenges traditional views of gravity's role in free fall. It references Galileo's experiments, which suggest that objects of different masses fall at the same rate, implying a distinction between gravitational and inertial mass. The argument presented posits that falling objects are effectively weightless during free fall, maintaining their initial orientation and position until they encounter resistance, such as the ground. This perspective suggests that the motion of falling objects is a passive response to the curvature of time-space rather than a direct effect of gravity. The theory argues that gravity is not the cause of attraction between bodies; instead, it is a result of time-space curvature. The discussion concludes that the observed behavior of falling objects may serve as a test for existing theories of gravity and general relativity, proposing a new understanding of mass, weight, and motion.

The mechanism of falling object is always an interested topic. Almost all physicists think that gravitational force acts on object and makes it have weight and free fall. Here a very simple experiment negates the above parlance.
Galileo demonstrates that different mass bodies increased their speed at the same rate (Stephen [1]). Galileo phenomenon implies that there may be two different mechanisms that govern it. One is the equality of gravitational and inertial mass based on facts that object has weight (Einstein [2]). Another is that falling object is not governed by gravity. Under this condition, falling object must be weightless and stay on how it is left in falling process. So, falling object is passive.
Let us see a very simple experiment.
A object, a solid iron ball (diameter is 4cm) with a long handle (diameter 0.5 cm and length 15 cm), is kept on balance by hand at angle 0,60,90,120 degrees with vertical line respectively in air showed in Fig. up-up A, B, C, D. Release the object, and then it is free falling. The angles of object in space are always not changing in free falling process showed in Fig up-down A, B, C and D. The object stays on how it is left. Its solid ball with big mass does not go further downwards than handle with less mass. When the process of free falling object is blocked by floor, it falls down on it at once because of weight showed in Fig up-down E.
Obviously, the object is weightless. Its weight does not exhibit, until it meets resistance. If it has weight in free falling process, the ball part with very big mass is very heavy and must be more downwards than light handle.
Weightlessness, unchangeable state and Galileo phenomenon are three properties of free falling object. Weightlessness verifies that Galileo phenomenon is not a direct consequence of the equality of gravitational and inertial mass.
Time-space or field of anybody is spherical. Its curvature direction points to center. The curvature direction of time-space of two bodies is always opposite. This is the reason why they attract each other. In their closing process, they respectively move from other’s low curvature to high. In a word, the motion of them is the direct consequence of time-space curvature contraction. Gravity is not the cause of attraction between two bodies. Any force including gravity is an index of resistance (Zhai [3]).
The time-space of the Earth is very big, but that of an iron boll employed in experiment limited. So, the Earth can be seen as a fixed body, the phenomenon of falling object is just the result of its time-space converging at center.
In this way, the curvature surface of time-space of the Earth on which object stays converges at its center. Object that follows the motion of time-space curvature surface falls showed in Fig 2. The motion of falling object is passive one. This is reason why object in falling process is weightless and continue in rest or motion. So, it is easy to understand why the acceleration of falling object does not concern with mass.
When object meets resistance, it gets behind the curvature surface motion of time-space that moves continually. So, weight that resists the change in height may be seen as an index of mass inertia, not gravitational force, because the change in quantities of mass only causes the change in weight, not in gravitational acceleration determined by curvature and curvature intensity of time-space (Zhai [3]). The change in weight is equal to that in inertia. This is reason why inertial and gravitational mass is equality and exactly proportional to one another. Weight is a direct consequence of passive motion of object that is blocked.
The converging motion of time-space at center is accelerated one. So, the object that follows it gains the same acceleration, then kinetic energy and momentum.
Any object or body that has three properties may be called free one. For example, gyroscope, spacecraft and instrument in it and Moon that can be seen as free object relative to the Earth. .
Obviously, here a very simple experiment demonstrates that falling object is the direct result of the converging motion of time-space or field at center, not gravity. The mechanism of falling object is the touchstone to test gravity and general relativity theory. My observed result and theoretical discussion may be a complement to Newton’s theory.

I am not sure that it is worth replying to someone who confuses the first and second names of the author of one of the most famous popular-science books. However, what I think you are trying to say is that, if a gravitational field gradient is sufficiently intense (or if an object is of sufficient extent) then different parts will fall at different rates. Well, obviously they would. This does not contradict Galileo.

Gallileo never said anything like that! What do you think "weightless" means?
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
