    Gravity Threads are Real

    To say something is possible means that you have some evidence for its existence. I don't see any evidence for gravity threads. There is clear observational evidence of various individual falling objects creating parabolic paths through the air. And the fact that everything free falls back to Earth suggests a force coming from the Earth. But where is the evidence that Earth creates gravity threads? When I asked about this, you said it hasn't been discovered how Earth creates them, but we know about them because of the way things move. Isn't this arbitrary? Why not imagine projectile elves that live in every object and guide it according to elven magic, which happens to make parabolas that fit with the math? That seems just as possible as gravity threads which mysteriously emerge from the Earth.

    Gravity Threads are Real

    What's wrong with the theory? It appears to be missing a spool. For the thread to take the shape of a parabola, the spool would be needed to unwind the initial thread and provide the initial involute. If only a portion of the entire involute is considered, it might get conflated with a parabola. The more developed involutes more closely resemble a spiral. Rather than traveling along the thread, what is being described is the endpoint, and the course it makes as it becomes unraveled from the spool, where if properly wound, serves as an excellent example of a helical coil. The specific gravity, in this case, might be derived from the weight granted to the original development in the vacuum of having left out the spool around which the original thread was packaged and subsequently unraveled from thereafter.

    1. I’ll begin with the most serious mistake and continue with the less serious ones. The premise of your “theory” is that the possible trajectories an object can take in free fall are in fact real. You call them “gravity threads”. In your view, an object follows a path by “attaching” itself to the “thread” corresponding to the object’s velocity. Until and unless the reality of the gravity threads is established, any speculations about details, e.g. how it would work in different circumstances, are absolutely useless. In the absence of a solid justification of your premise, your “theory” is neither true nor false, it is simply arbitrary. This essential objection was already made by MisterSwing - but you failed to comment on it, which is unfortunate... Besides, yours is not a theory, it is a hypothesis - at most ! 2. You did not justify the necessity of revising the classical Newtonian theory of as applied to free fall: non-concordance with observations, possible gaps in the theory and so on. In the classical theory the various trajectories are potentialities, only one will be taken in reality, depending on the initial velocity (value and direction) and the strength of the gravitational field. 3. You say nothing about how it would be possible to prove the reality of the “gravity threads”. 4. If the trajectories/“gravity threads” are real, it should be possible to observe them. For this they should interact with our senses or instruments, and thus they probably have to possess some energy. Because you postulate an infinity of such “gravity threads”, you have an obvious problem: one will need an infinite energy to create them (at least a continuum infinity of the 6-th order!!) 5. I will also mention one of the least important mistakes. You write that “in space above the Earth and within the Earth's influence, Threads all follow parabolic arcs”. This is false: even in the absence of any other force beside the Earth gravity (such as air resistance), the parabolic arcs (y=Ax+Bx2) are only approximations - namely second order approximations. Even in the ideal case, the true trajectories are (almost) never parabolas. Details – on demand. PS: wrong is also your question addressed to the audience: “What’s wrong with the theory?”. This question is wrong from the point of view of the onus of proof rule.

    The Foundation for Economic Education recently published an article about millionaire Bernie Sanders with the title, "Bernie Is a Capitalist, Whether He Likes It or Not." Although this may be true of the first of the following dictionary definitions of the term, it is patently false about the second: 1. a person who has capital, especially extensive capital, invested in business enterprises. 2. an advocate of capitalism. 3. a very wealthy person. I would emphatically add that it's debatable, to say the very least, that "he deserves that money." It is his property, under capitalism, and he did gain it by trade. To that extent, it is proper that he has the money. But he did so while advocating an immoral and impractical -- a vile and deadly -- ideology. In that sense, he "deserves" that money in the same sense that a chiropractor or a fortune teller deserve whatever they receive from others, and he should thank his lucky stars for the remnants of capitalism that are allowing him to get away with it. I do, believe it or not, for reasons analogous to criminals sometimes walking free in our justice system: It's the price we pay for the protection of the rights of the individual being the default in our government. Or which, like private property ought to be default, but which Sanders and his ilk want to finish turning into "51 percent of people choos[ing] something, and the other 49 percent have to go along." This article, sadly and tellingly, does not convey outrage or even alarm that this is an increasingly accurate description. The piece does contain other interesting information -- such as a link to the instructions Sanders could follow to volunteer for income equality, were he sincere about his advocacy of the same; and it does indicate that socialism calls for government coercion. But it misses a big opportunity to make a case against Sanders that would really hurt: a moral one. As Ayn Rand once pointed out to FEE founder Leonard Read: Image via Wikipedia, public domain.The mistake is in the very name of the organization. You call it The Foundation for Economic Education. You state that economic education is to be your sole purpose. You imply that the cause of the world's troubles lies solely in people's ignorance of economics and that the way to cure the world is to teach it the proper economic knowledge. This is not true -- therefore your program will not work. You cannot hope to effect a cure by starting with a wrong diagnosis. The root of the whole modern disaster is philosophical and moral. People are not embracing collectivism because they have accepted bad economics. They are accepting bad economics because they have embraced collectivism. You cannot reverse cause and effect. And you cannot destroy the cause by fighting the effect. That is as futile as trying to eliminate the symptoms of a disease without attacking its germs. [bold added] (Letters of Ayn Rand, pp. 256-257)FEE would have done better to point out that Sanders, like many others who have become the first kind of capitalist -- including many who truly deserved their fortunes, like Bill Gates -- are far from being the second kind. More broadly, they could have noted that unless more of us become the second kind of capitalist, there won't be any of the first kind for much longer. -- CAVLink to Original

    Gravity Threads are Real

    The basis for the involute is a spool (cylinder) from which an actual thread endpoint could be used to 'describe' an arc as it is unwound, shifting the 'gravitation thread' into a different context. It would take a pretty short portion of a parabola to superpose it on an involute and identify it as visually indistinguishable. Math is derived from reality. And like many other concepts learned, having used them for many years without issue, the initial formation of one, two, three, is lost back in childhood, and even with the guidance of a Pat Corvini, can be difficult to reclaim a clear notion of the relationships involved, and more difficult to explain to others. As math moves beyond the measurement of straightforward counting, the 'what' gets harder to separate from the "how".

    The math leads to Galileo's experiments with projectile motion, right? The parabola is therefore a relational existent between the object and its trajectory. A gravity thread represents the reification of a relational existent that has been separated from its object. Without the cannonball flying through the air, there is no objective basis for the parabola's existence.

    To bounce off this... What is your educational background in physics? My main comment is I'm wondering about the foundation this is based on. I really am curious.

    A great mind once said: "Things having possible attributes or properties can always be mentally inverted with a background of attribute or property having a propensity to manifest as a thing."

    The ax^2+bx+c is the form Newton and Galileo used from the framework of the historical point in time which they made their observations. According to a long lost ancient Pythagorean text, the exact shape of the gravitational threads would have also been dependent on whether they had been formed by being cut or being rolled.

    I'll begin with some specific items: 1. I am puzzled by the use of "infinite" to describe the threads. Do you mean they are "without a limit" or "impossible to count"? If they have a limit, perhaps using "innumerable" in the beginning would help. I notice you used that adjective in the end. 2. Why do gravity threads emerge from points in space? What causes them to emerge and how? You say Earth creates them, but how? 3. How does an object attach to a gravity thread? What does "attach" mean here? 4. When an object shifts from one thread to another, what is its thread status while in transition? Is it attached to a thread even while shifting from one to the other? 5. You say that "absent other influence" an object is attached to its "perfect gravity thread." But isn't an object always influenced by Earth's atmosphere, unless you place it in a vacuum? So, under normal circumstances, would the object ever be attached to its perfect gravity thread? More generally, when I think of gravity, I think of Isaac Newton. What do you think he got wrong, if anything?

    This "theory" is a joke, sorry. E.g. “SOMETHING out there needs to be guiding objects as they fall…” Are you the author of this "theory” ? Besides, reminds me strongly of the disastrous Theory of Elementary Waves by Lewis D. Little, enthusiastically embraced, then abandoned, by some Objectivists. It assumed that “something” is guiding particles, namely mysterious but ubiquitous “elementary waves”. So – here we go again…

    I suppose in every endeavor of his life he generally had been able to size up the competition, adapt, and respond as need be, or at least understand. Here he must have felt a little in the dark. Knowing Dagny's past lovers might give him just a little more insight into who she is, what makes her tick, what she likes, and who, in her memory, he may be in competition with, whether she is conscious of that comparison or not. Being strong and confident generally means a man knows his worth, but working out how a woman responds to him and whether that is consistent with his self view or whether he needs to update it, himself, or her view, is still an exercise worth doing. Please note that Hank was not perfect by any standard... he was always on a personal journey. and in any case being reflective and introspective as well as sensitive to a very close relationship could only help in his goal to understand and improve himself and likewise understand and improve his relationship with Dagny. So asking about past lovers as such is not always a sign of weakness, it depends much on the motivation for doing so, both emotional and cognitive.
