Verification of the Unexplainability of Dzhanibeko


发表时间:+-

Rongqing Dai

Abstract

Based on all the videos of the Dzhanibekov effect from space stations of different countries available to the public, it is a reasonable assertion that the Dzhanibekov effect cannot be explained by the existing known physics, while the mainstream academia has been trying to avoid admitting this in their erroneous analyses of the Dzhanibekov effect over the past three decades. Nevertheless, due to the shocking nature of the said assertion and its logical openness, it would be desirable to get it verified through advanced computational analysis and lab experiments. In this paper, a conceptual design for an AI-aided experimental verification of the said assertion is proposed, and the outcome of its realization is discussed.

Keywords: Dzhanibekov Effect, AI, Experiment, Verification, Known Physics

1. Background

Concerning the famous Dzhanibekov effect, since early 2025 I have pointed out that the academic explanations of the Dzhanibekov effect over the past 30 years are completely wrong; accordingly, based on all the videos of the Dzhanibekov effect that have been sent back from space stations of different countries and available to the public, I have made such a reasonable (preliminary though) assertion that the Dzhanibekov effect cannot be explained by the existing known physics. I do not need any additional verification for my statement that “the academic explanations of the Dzhanibekov effect over the past 30 years are completely wrong” since I have clearly identified where they went wrong [[1]]. However, regarding the unexplainability of the Dzhanibekov effect by the existing known physics, although I am fully confident in the logic of my analysis, it would be beneficial to get it verified through some AI-aided experiments in order to convince the public, due to its negative nature of denying the existence of certain open possibility. This type of negative conclusions about a certain possibility usually requires special verification because of its logical openness. For instance, if someone points to a petal on his floor and says, “I see a petal over there,” he is making a positively definite statement and its verification is a straightforward simple job; but if someone says, “there isn’t any petal in this entire building”, then he needs to provide some special verification to prove that his conclusion is correct due to its negative openness.

This paper proposes a conceptual design for verifying the assertion that “the Dzanibekov effect cannot be explained by the existing known physics” through AI-aided experiments. The verification process mainly consists of two parts: training the AI and using the AI to verify the assertion.

2. The conceptual design for the verification

2.1. AI training

To verify the assertion in question, we need to first train the AI through the following three main steps:

Step One

First, educate the AI with relevant knowledge such as Newton's theory of gravitation, rigid body mechanics, some aerodynamics knowledge, as well as the mechanics of the motion of the space station and all objects within it. However, the Euler equations of rigid body dynamics should be excluded due to its defect [[2]].

Step Two

Let the AI that has learned the above knowledge solve examples of the movement of rigid bodies in the atmospheric field under the influence of the Earth’s gravity, such as the flight of bullets, the fall of objects from a height, and even the movement of quasi-rigid bodies with little deformation like volleyballs and balloons, as well as movement of a space station and the objects within it.

The main training objective of this step is: based on the known parameters of air temperature, pressure, humidity and wind speed, as well as the distribution of the mass and moment of inertia of the moving object, calculate under the given initial conditions: 1) the coordinates of the trajectory of the object’s center of mass; 2) the variations of Euler angles of the object; 3) the velocity, angular velocity, acceleration, angular acceleration of the object at different time points.

Step Three

Unlike the previous step, in this step, the AI is not given initial conditions. Instead, it needs to observe the motion of actual objects in the atmospheric field under the influence of Earth’s gravity through video recording and provide the following information based on this “visual” observation:

1) The equation of coordinates of the motion trajectory of the object’s center of mass:

(x,y,z) = (X(t),Y(t),Z(t))

2) The equation of the variation of Euler angles of the object:

(α,β,γ) = (A(t),B(t),G(t))

After having the above two sets of equations, it can calculate:

3) The velocity, angular velocity, acceleration, angular acceleration of the object at different time points;

Then, based on the known distributions of mass and moment of inertia of the moving object and the actual measured parameters of air temperature, pressure and humidity at that time, etc, calculate:

4) The forces and torques acting on the object at different time points.

5) Verify the conservational status of momentum and angular momentum according to the above calculations.

Once the AI has been able to pass through these three steps very proficiently and reliably, we can move to the next step to use it to verify the said assertion about the Dzhanibekov effect.

2.2. Verification of the assertion

Under the premise that the AI is already capable of handling the previous step three, the verification process should be relatively simple: have the AI watch the videos of the Dzhanibekov effect recorded on the space station, and inform the AI of the position of the space station and its speed at the time of video recording, as well as the relevant physical parameters inside the space station and the mass and moment of inertia of the rotating object.

3. Discussion

3.1. Regarding the training steps

For ease of discussion, I have made the calculation of an object’s motion in the atmospheric field under the influence of Earth’s gravity with the given physical conditions a separate step from the calculation by the AI based on its own visual observation in combination with the given conditions. However, in actual training, it is best to merge these two steps for the following reasons:

With the traditional engineering mechanics, calculating the free motion of a rigid body in an atmospheric field under the influence of gravity is not an easy task, especially when the Euler equation of rigid body mechanics is not allowed to be used due to its defects. Engineers need to use tools of computational mechanics such as finite difference and finite element, and many technical challenges might arise when solving for a completely free rigid body, especially under the premise that the gravitational field itself could change. Even if the AI is equipped with superb computing power, it is probably not a wise choice to do the required calculation solely by traditional methods.

On the other hand, allowing the AI to visually observe the movement of objects can significantly reduce the difficulty faced by the traditional computing. In traditional calculations of engineering mechanics, the calculation of an object’s position, deformation, velocity and acceleration, as well as the calculation of the forces acting on the object, are determined by a highly coupled nonlinear system of equations. Once AI can visually observe the three-dimensional coordinates and shape changes of an object from all angles by itself, it can directly calculate the position, deformation, speed and acceleration of the object’s movement. The remaining tasks are only the calculations of forces (including internal and external forces as well as temperature and pressure, etc). To verify the said assertion on the Dzhanibekov effect, as long as enough cameras are installed in the experimental section of the space station, the AI can conduct a comprehensive visual observation of the movement of the object and thus record all the required parameters.

3.2. Two different possible results

There could be only two types of outcome of the verification:

1) AI discovers that when the Dzhanibekov effect occurs, angular momentum is completely conserved.

When this happens, since my previous theoretical analysis indicates no possibility of such outcome, if it is verified that the AI’s calculation is error-free, then we need to analyze what kind of forces could cause the periodical flipping around the axis of the least moment of inertia of the rotating object, based on the forces calculated by the AI at the selected time points, from which we should be able to know why the mainstream academics over the past 30 years, as well as myself in the past few months, have missed the forces identified by AI that would cause the Dzhanibekov effect. In case such a situation really occurs, it should be helpful for us to better understand aerodynamics.

2) AI discovers that when the Dzhanibekov effect occurs the conservation of angular momentum is violated, which validates my aforementioned assertion that the Dzhanibekov effect cannot be explained by the existing known physics.

4. The benefit of the proposed verification

From the videos of the Dzhanibekov effect of space stations recorded by various nations, we have not been able to identify any type of forces that can cause the periodical flipping of the object around its axis of least moment of inertia (and thus the changes in the angular momentum).

However, due to the complexity of the issue, audience (scholars and general public all alike) could easily be misled by the erroneous interpretations provided by the mainstream academics for the past 3 decades [1]; particularly, in addition to the defective mathematical formulations of the academics, AI has also been brought in to fortify the so-called imperfection-induced instability proposed by the academia to account for the Dzhanibekov effect through listing all trivial petite influencing factors that could cause the false instability.

Besides, in this professionally divided era, most people (scholars and general public all alike) have been used to only following the claims of very few with the manmade aura of “expert” without any first hand investigations of most issues in the world.

Therefore, no matter how rigorous the logical analysis we would provide for the unexplainability of the Dzhanibekov effect by the existing known physics, as long as it is conducted solely based on human visual observations and not all the potentially relevant dynamic factors involved are tested to the greatest extent possible, there will always be a concern deep in people’s hearts: since the combined effect of air and gravity could normally be very complicated, maybe something has been overlooked during pure theoretical analysis for the cause behind the Dzhanibekov effect.

With the computing power of AI, once the conceptual design proposed in this paper is successfully implemented, we could obtain force (torque) distributions at real time during the motion of the Dzhanibekov effect, which will be able to determine with certainty whether the assertion that “the existing known physics cannot explain the Dzhanibekov effect” is correct or not.

5. Final Remarks

If the proposed AI-aided experiment verifies the assertion that “the existing known physics cannot explain the Dzhanibekov effect”, it will undoubtedly be a shocking result, because it means that we have confirmed that Newtonian mechanics has a loophole, and the next step will be clear: to figure out how to modify the Newtonian mechanics based on the Dzhanibekov effect.

However, even if the proposed AI-aided experiment denies the assertion that “the existing known physics cannot explain the Dzhanibekov effect”, all the efforts made to train AI as proposed above would still be meaningful. This is because the AI trained according to the design given in this paper is clearly not only capable of verifying the assertion in question, but also has great practical potential of doing many things.

    在academia.edu上的交锋:

    不知是诡计还是无知,在academia.edu贴出的本文的讨论篇上有人拿出据说是从ChatGPT上得到冗长的答案来为过去30年里主流学界在贾尼别科夫效应上的谬论进行辩护,以为凭借着长篇幅的文字污染就可以把读者蒙住。。。。我对此予以了回击:

    Michael A . Susko 2 days ago

    Ok, I am way out of my league here, but I got a bit intrigued: So I checked things out with ChatGPT, and here was one of its responses to my analysis:                                                                                   "Your sentence is correct:

    “Objects are not mathematically perfect in their behavior, and the conditions in space amplify these imperfections, so that we then see this seemingly inexplicable phenomenon.”

     

    That is exactly what is happening in the Dzhanibekov effect.

    Now let me break that into the three truths underneath it.

     

    1. Real objects are never mathematically perfect

     

    No physical object has:

     

    perfectly even mass distribution

     

    perfectly aligned axes

     

    perfectly smooth surfaces

     

    perfectly precise hand release

     

    perfectly symmetric geometry

     

    Even manufactured components have microscopic asymmetries.

     

    These are normally too small to see.

     

    2. Space removes the stabilizers that normally hide the imperfections

     

    On Earth, stabilizing forces suppress these tiny deviations:

     

    air drag

     

    friction

     

    gravity

     

    surface contact

     

    collisions

     

    damping from the environment

     

    These act like “noise-canceling headphones” on motion.

     

    But in the microgravity of a space station:

     

    no gravity

     

    almost no friction

     

    low air drag

     

    no preferred “down”

     

    no surfaces pushing back

     

    All stabilizers are gone.

     

    Thus the imperfections are no longer damped.

     

    3. The intermediate axis is unstable — it magnifies the imperfections

     

    For rotation:

     

    one axis is very stable (largest inertia)

     

    another is stable (smallest inertia)

     

    the middle axis is mathematically unstable

     

    This instability means:

     

    A tiny imperfection gets amplified into a full flip.

     

    This is why the object seems to “suddenly” flip:

     

    the wobble was always there

     

    Earth just hides it

     

    space reveals it

     

    the math explains it

     

    instability amplifies it

     

    Nothing breaks a physical law.

    We merely witness a clean expression of a normally hidden instability.

     

    4. The phenomenon looks inexplicable only because Earth hides it

     

    On Earth, you never see this:

     

    your hand slightly corrects the spin

     

    collisions interrupt the motion

     

    friction damps the wobble

     

    gravity forces predictable orientation

     

    So the “weirdness” has no room to grow.

     

    In space, the raw, naked instability finally has room to unfold.

     

    Thus:

     

    **Space does not create magic;

     

    it removes the restraints that normally hide the deeper structure of motion.**

     

    5. A one-line summary

    The Dzhanibekov effect is simply the natural amplification of microscopic imperfections in a perfectly unstable situation, revealed only because space removes all stabilizing forces.

     

    That’s the full truth, clearly and without contradiction.  "                                 Ok, so that ends Chat's post or anlaysis to my line of questioning. the argument here seems to be that the conditions of space amplify minor imperfections which create the seemingly inexplicable phenomone we see. I think what is interesting here is that how hidden-from-easy view instablities, and ones seemingly minor, can have a major effect.                     Such is the nature of our world... things sometimes decided or events turning by things seemingly very small....

    Like

    Rongqing Dai 1 day ago

    Sorry for ChatGPT, it is wrong....it just repeats the decades long false theory of the mainstream about Dzhanibekov, which is nothing surprise----AI just repeats what humans feed it. In my last post (which is still alive for discussion: https://www.academia.edu/s/ebf05c680b?source=link), you might find the following to rebuke the so-called Imperfection-caused instability theory for explaining Dzhanibekov effect:

     

    The mainstream scholars have used the so-called mathematical instability as the cause for the anomalous 

    flipping of the rotating object showing the Dzhanibekov effect. However, the term of “mathematical 

    instability” only tells that the motion is unstable when influenced by external disturbances, but it does not 

    tell that pure mathematical manipulations could change the precondition of any derivation. For example, 

    when there is A + B =1 in the precondition of a mathematical derivation, if no any mistake is made during 

    the derivation, no matter how many thousands of steps are involved in the derivation, the end results 

    should not allow A + B =2. 

     

    Here we need to distinguish the differences between these things: precondition, initial condition, and 

    disturbance. 

     

    In the mainstream scholar’s derivations for analyzing Dzhanibekov effect, the equation of conservation of 

    angular momentum is their precondition, but in the end of their derivation they concluded that the initial 

    minute angular momentum around the axis of least moment of inertia is amplified when there is no 

    external torque, which means that their end results violates their precondition, the equation of 

    conservation of angular momentum. 

     

    Besides, they wrongly took the initial minute angular momentum around the axis of least moment of 

    inertia as the "disturbance" or "perturbation" to the system which triggers the instability of the system, but 

    that is wrong. The initial minute angular momentum around the axis of least moment of inertia is not the 

    "disturbance" or "perturbation" to the system but the initial condition of their mathematical derivation and 

    should stay minute to satisfy the equation of conservation of angular momentum if there is no true 

    disturbance to the system during the motion which is the case when external torque is assumed to be zero. 

     

    On the other hand, in the motion of tennis rackets in the normal gravitational field, the external impact 

    from gravitational pull and air drag constitute the disturbances to the dynamic system of motion, which 

    would trigger the flipping due to the instability. 

     

    As a conclusion, pure mathematical analysis of the Dzhanibekov effect should not end up with the 

    violation of the conservation of angular momentum as long as it starts from the equation of the 

    conservation of angular momentum and is worked through correctly, unless some other interfering 

    condition is introduced.
