| Bjoern Feuerbacher <[Only registered users see links. ].uni-heidelberg.de> wrote in message news:<[Only registered users see links. ].uni-heidelberg.de>... Ok. Let me focus on this particular paragraph first as it is the core of his other comments. He stated (below after it is the complete text where it is acquired. He emailed the first chapter of his book to people): "Consider the situation where an object is simply too heavy to move, despite all efforts to push it. There is no question that one could expend a tremendous amount of effort and energy attempting to move the object, yet never actually manage to move it an inch. However, applying the Work Function as a "work detector," it calculates that zero work was done. A tremendous amount of force was applied to the object, but the object was nevertheless moved zero distance, and since work equals force times distance, the Work Function calculates that zero work was done. If this were further taken to mean no energy was expended, we would have a worker who is exhausted from attempting to move such a heavy object, yet who is considered to have expended no energy. Of course, this is obviously a serious misapplication of the Work Function that brings nonsensical results, yet this is precisely the logic used to justify the gravitational force, as we will see shortly. The Work Function is only designed to help organize and qua ntify situations where a force clearly moves an object through a distance, but is not meant to function as a generic "work detector" that further tells us whether any energy was expended by an arbitrary event." Now the complete text: "(Error) The Work Function - A Flawed Explanation Physical labor typically involves moving heavy objects or material from one place to another. The heavier the object and the further it is moved, the more energy must be expended in the process. The Work Function is merely an attempt to describe this fact using a simple equation - originally designed to help engineer mechanical devices that use energy to do work, such as steam engines that burn fuel to move trains. This equation is written as W = F d, which is read as work (W) equals force (F) times distanc e (d). That is, the more force required to move an object, and the further the object is moved by that force, the more work is done in performing this task. The Work Function can be a very useful tool in analyzing and quantifying the amount of work done by a given process or machine, and has served engineers well for over a century. However, serious problems arise when its use is extended beyond its design intent. Its original purpose was as an engineering tool to compute how much work is done when a force moves an object across a distance, which also corresponds to how much energy was expended, since an equivalent amount of fuel must be used in the process. Th is all seems quite reasonable; however, over the years the Work Function has undergone a subtle and surprisingly deceptive transformation into a "work detector," whose result is taken as the final word on how much energy was used in any given process. This is such a subtle yet powerfully deceptive transformation that it needs to be clarified with an example: Consider the situation where an object is simply too heavy to move, despite all efforts to push it. There is no question that one could expend a tremendous amount of effort and energy attempting to move the object, yet never actually manage to move it an inch. However, applying the Work Function as a "work detector," it calculates that zero work was done. A tremendous amount of force was applied to the object, but the object was nevertheless moved zero distance, and since work equals force times distance, t he Work Function calculates that zero work was done. If this were further taken to mean no energy was expended, we would have a worker who is exhausted from attempting to move such a heavy object, yet who is considered to have expended no energy. Of course, this is obviously a serious misapplication of the Work Function that brings nonsensical results, yet this is precisely the logic used to justify the gravitational force, as we will see shortly. The Work Function is onl y designed to help organize and quan tify situations where a force clearly moves an object through a distance, but is not meant to function as a generic "work detector" that further tells us whether any energy was expended by an arbitrary event. Now, to complete the improper transformation of the original Work Function from a simple engineering tool to a generic "work detector," it has evolved from its original form of W = F d to its current form W = F d cos(theta). The additional term here, cos(theta), is the cosine function, which transforms any angle from 0 to 360 degrees into a value that lies between -1 and 1. Therefore, the original result from the Work Function calculation is now multiplied by a value between -1 and 1 that corresponds to the angle (theta) between the direction the object is pushed and the direction it actually ends up moving. If the object simply moves in the direction it is pushed, which is the usual case, this zero-degree angle between force and movement results in the work calculation being multiplied by 1, since cos(0) = 1. This means nothing changes from the original Work Function when force and movement are in the same direction. However, if the object somehow managed to move completely sid eways despite a forward push b eing applied to it, this 90-degree angle between force and movement means the resulting work calculation must be multiplied by 0, since cos(90) = 0. Therefore, the work done in this scenario would be calculated as zero. This modified Work Function, W = F d cos(theta), is said to calculate the amount of useful work, since only the amount of work done in the direction of the force is considered to be desired and therefore useful work. This is how the Work Function is taught today, which now sets the stage to explain why the previously mentioned violations of the laws of physics by Newton's gravitational force cause no particular concern for most scientists. First, the issue of objects being held to the planet's surface by a force that has no known power source is easily dismissed by noting that an object held down by the gravitational force does not move. If the object doesn't move, there is no work done according to the Work Function, a nd therefore no energy is expended and no energy source is required to explain how things are forcefully held down by gravity. The serious law violation that results from gravity forcefully holding objects to the planet's surface with no known power source suddenly vanishes. This is the same flawed logic used earlier, which left our worker exhausted after trying unsuccessfully to move a heavy object despite having apparently expended no energy. Yet, of course, both the work er and gravity must expend energy in these examples. In similar fashion, the modified Work Function is used to justify the tremendous energy required to hold our moon in orbit, again with no known power source. Since the moon is actually traveling past the Earth in a straight line but is continuously constrained in its orbit by the gravitational force pulling it down toward the planet, this is considered to be a situation much like an object that slides sideways when a force pushes forward. The angle between the direction of the moon's travel past the Earth a nd the direction of gravity pulling down is the same 90-degree angle as in the earlier example of the sideways-sliding object, meaning the Work Function must be multiplied by 0. This gives the result that the gravitational force does zero useful work and thus expends no energy in constantly constraining our moon from flying off into space, removing the need to look for a power source. Once again, a serious violation of the laws of physics suddenly vanishes. Yet, a person who m ust constantly struggle to cons train a heavy, speeding rock into traveling in a circle on the end of a rope might disagree with this zero-work, zero-energy conclusion for orbits. Finally, there is the situation where objects fall straight down. Surely the Work Function would have to give a non-zero result here since the direction of movement is in the same direction as the downward pull of gravity. Indeed, the Work Function does calculate a positive amount of work, which should mean energy has been expended by the gravitational force, requiring an energy source be identified within the Earth that is drained by an equivalent amount if this event is to remain within our laws of physic s. Since there is no such energy source known to science, we must either admit that Newtonian gravity cannot be scientifically explained, or arrive at some further justification. Indeed, an additional logical abstraction has been invented for this type of situation to avoid the search for a power source, which runs along the following lines: In order for an object to drop from a given height, work had to be done earlier against the pull of gravity to lift it to that height in the first place. Since this upward lifting could be considered negative work from the perspective of the downward-pulling gravitational force, the positive work done by gravity when the object falls could be considered to cancel with this earlier negative work. This zero overall work then corresponds to zero net energy expenditure, and thus we are once again saved from loo king for the energy source for gravity. Of course, this abstract exercise overlooks the physical reality that the falling object must still somehow drain gravity's unknown energy source, and no known theory states how lifting the object earlier would have charged this power source in order to compensate for this later energy drain. Further, this explanation implies the existence of such a mysterious and currently unknown power source, which is the very issue it was invented to avoid. So the "energy balance" in this logic is a meaningless abstraction that merely diverts attention from the physical law violation that gravity somehow pulls objects to the ground while expending no energy. Once again, the reason this logical conundrum has arisen in our science is due to the deceptively subtle, yet powerful difference between using the Work Function to describe clear situations where a force moves an object through a distance, and using it as a generic "work detector" in all situations. In fact, in the case of Newtonian gravity, not only has the Work Function been misused as a "work detector" but also as a "force authenticator." That is, not only is it used to alleviate concerns about law viol ations by calculating that the gravitational force does no work and expends no energy, but it is put to this use in order to help justify or authenticate the very existence of the gravitational force. After all, any theory involving a force that violates our most fundamental laws of physics is unacceptable as anything other than a purely abstract model of a still unexplained physical process. It cannot literally be taken as the proper physical explanation since this is precisely why our laws of physics exis t - as a litmus test or sanity test for such proposed new ideas. The Work Function is simply intended to describe the work done by known forces as they move objects, but here it is being used in an attempt to authenticate the existence of the previously unknown force introduced by Newton - a force that is otherwise scientifically unexplainable. This misapplication of the Work Function essentially creates a loophole in the Law of Conservation Of Energy, corrupting the original purpose of both of these concep ts. This Work Function discussion shows the type of logic that keeps most physicists from acknowledging that Newton's gravitational force violates the Law of Conservation Of Energy. However, once the flawed Work Function explanation is exposed and removed, there are simply no excuses remaining for this unexplained force. The rationalists of Descartes' time had good reason to see Newton's gravitational force as a return to the magical thinking of the past. Perhaps in Newton's day it was reasonable to expect that future generations of scientists would find a scientifically viable explanation or even a true power source for the gravitational force. However, three centuries later we have found no answers, instead opting to turn a blind eye to its violations of our laws of physics by installing a flawed logical justification for this force into our science. Regardless of its original purpose, the Work Function has now been incorporated into our science in such a manner that most scient ists clearly believe a zero-value result from its calculation always means there has been no expenditure of energy. This has led to the logical oversight that gravity need not expend energy to hold objects to the planet, since there is no motion involved, nor to constrain the moon from speeding away, since the pull of gravity is perpendicular to the moon's orbit. This state of affairs exists because we very much want to believe in this force. For centuries it has been the only reasonable explanation we have had, and in fact, it is still the only compelling and intuitive physical explanation for falling objects and orbiting moons even today. The official position in science today does state that another viable explanation exists in Einstein's General Relativity Theory of a "warped space-time continuum," but this does not address our everyday experiences and seems far off the mark compared with Newton's intuitive gravitational force. And indeed, as shown in the following chapter where the new principle is introduced, gravity can be explained in a simple, intuitive, and scientifically viable manner - but without appealing to either an unexplained force or an abstract and largely incomprehensible "warping of space-time." -------------- cinquirer note: The author above also attacks the laws of gravitation. But let's focus on the work aspect first. His argument being that not only moving object from position ot another requires work but also steady position such as a man lifting a 10,000 ton car. Even if no distance is made, he exerts work. Use his words above when arguing point by point. c |

This is a fine example of why argument by analogy is a logical fallacy. You'll see the crackpots and woo-woos doing a lot of argument by analogy. Learn to spot it, learn to recognize when and why a conclusion doesn't follow from the argument. When you strain against an object too heavy to lift, sure enough, no matter how much effort was put into it, no work was done on the object. If it were, it would have gained potential energy, or frictional heat would have been generated. The person doing the pushing has neurons firing, muscle fibers twitching with actin and myosin sliding across each other, ATP used up to fuel the effort. Work is certainly done internally, hidden by skin. But still no work done on the object. Momentum is still conserved, energy is still conserved because the wasted effort creates heat, entropy marches inexorably on. There's no law of conservation of effort, and there's no law that says the work done on an object is equal to the work done by the person pushing the object. Gravity doesn't use up energy on an immobile object because gravity doesn't have muscle fibers, so making an analogy between the energy expended by muscles and the energy expended by gravity is fallacious. To head off the next round of questions, gravity doesn't have an internal combustion engine, either. -- "Let us learn to dream, gentlemen, then perhaps we shall find the truth...

Strictly speaking, Work = I[(F).(R)] where I is the integral sign, F and R are vector quantities of force and displacement, and . is a vector dot product. Thus a work done by a variable force acting in 3 dimensions is equal to I[FxRx + FyRy + FzRz]. In other words, a force acting in the y direction only affects the displacement in that same direction. Work can also be expressed as a change in kinetic energy, Kf - Ki, or W = 1/2mVf^2 - 1/2mVi^2. Of course! Energy is DEFINED in terms of Work. Energy is the ability to do work; consequently there is an intrinsic relationship between the two quantities which much always exist. Without work, there is no energy; without energy, there is no work. This is such a subtle yet powerfully Effort is not energy in a Physics sense. Right. And it makes sense, even if you consider work in a non-physical sense. If you are trying to push an object, but aren't getting anywhere, you aren't doing work (actually, in all likelihood a small amount of work would be done by muscular movements internal to the person). You're just pushing a wall. Do you think anyone would get paid for pushing against a block that's too heavy to move? Change work to banana. All the Physics still applies, but his argument no longer has any logical merit because the work he is talking about above is not banana. Playing semantics with words and definitions isn't logic. Not with the present definition of energy... Again, this is a grade school definition of work, but its roughly correct. Which law? It doesn't violate conservation of energy, because conservation of energy is defined in terms of energy which is defined in terms of work. Not with the present definition of energy. Energy is defined in terms of work. None of this is relavent, since he isn't using his terms properly. In any event, energy isn't "expended." I don't ever recall hearing that Physics required things to have power sources. Power is just a rate of change of energy. Actually, gravity probably does some work on the moon. The moon's orbit is ellipical (as are all heavenly bodies) not circular (though very close), so at certain points the object would be speeding up or slowing down. However, work is an integral, so while at places the object will be speeding up, in one complete revolution, an equal and opposite negative work will also be done. In a given interval less than an entire revolution, work would be done however. Again, I ask which law of physics states that things need power sources. Which law? Newton's third law would be what they are experiencing. They are applying a force to cause the rope to spin, equal to V^2/R. The rope is applying an equal and opposite force on their arm. Neither force is doing work, however. Gibberish. Laws of physics say nothing about energy sources. Newtonian gravity isn't perfect, General Relativity expands on it in many ways. However, in the cases we are dealing with, classical Physics explains the results consistently, accurately, and effortlessly. The problem here is that the author has no concept of how Physics works. What is this obsession with power sources? If anything, a power source for a force like gravity would be more likely to violate conservation of enegy than anything else. Energy is an abstraction. It has no "source." It is an intrinsic property of objects that are moving or want to be moving (eg are constrained from doing so) Again with the power sources. Take a first year Physics course. Energy balance means nothing. My heavens, the last 200+ years of scientists have worked really hard to cover up this conspiracy. Amazing how many inventions were based upon these flawed principles, but still manage to function. It's as if no law is being violated at all... Which laws? Newton invented the concept of forces (more or less). He introduced a lot of "unknown forces" such as normal forces, friction, gravity, etc. The work function, however, was developed AFTER Newton's Laws by Joule, almost 100 years after. That means that it could not have been a justification for gravity, because it was not invented. Conservation of Energy is defined in terms of Energy which is defined in terms of work. (My, I seem to be repeating myself) There is one simple problem. The work function does exactly what it is supposed to. It's predictions are very reliable, very accurate, and very easy to verify. GR is not "another explanation" for gravity. It is an expansion on the basic rules of the gravitational force. Unless I am very much mistaken, GR predictions coincide with those predicted by Newtonian mechanics for things like planetary motion. I would be interested in seeing how this "scientifically viable" manner corresponds to the evidence. In short, as I've stated in several places above, "The Final Theory" is not a Physics book, nor is Mark McCutcheon an authority on even the most trivial elements of physical law. He plays with definitions, uses faulty logic, twists the facts, and invents concepts (power source, etc.) that have no physical significance in order to justify his claims. He's a crackpot. A. |

| [Only registered users see links. ] (Gregory L. Hansen) wrote in message news:<bpjt6a$uqu$[Only registered users see links. ].indiana.edu>... He is talking about orbits of planets. I think let me mention the following to put what he stated in perspective. The following text came before the above text was shared. Anyway. This author gives out the first chapter. His web site is [Only registered users see links. ] "- 1 - Investigating Gravity The Theory of Gravity Gravity as One of Four Basic Forces in Nature Gravity is one of the most fundamental and familiar forces of nature. As such, before discussing gravity in particular, it is important to clarify what the forces of nature are considered to be and how they relate both to Standard Theory and to our ultimate quest for understanding. Although Standard Theory is a composite of many sub-theories, some of which were listed earlier in Figure 1-1, most scientists believe the search for the Theory of Everything is a quest to understand and unify what are currently considered to be the four separate fundamental forces of nature: Gravity - the familiar attraction between all matter, first described by Isaac Newton. Electromagnetism - the closely related phenomena of electricity and magnetism, as well as electromagnetic radiation such as radio waves and light. Strong Nuclear Force - a powerful, short-range force thought to be holding atomic nuclei together. Atomic nuclei have many positively charged protons in close proximity, which should strongly repel each other and cause the nucleus to fly apart according to the theory of Electric Charge. Therefore, the concept of an attracting Strong Nuclear Force between protons in the nucleus was introduced to explain how the nucleus is held together in apparent violation of Electric Charge Theory. Weak Nuclear Force - another nuclear force, considered to be much weaker than the Strong Nuclear Force. Phenomena such as the random decay of populations of subatomic particles (i.e. radioactivity) were difficult to explain until the concept of this additional nuclear force was introduced. It is currently believed that these are the four fundamental forces in nature, and that, in essence, they are merely different manifestations of one single underlying force or principle that has so far eluded science. To discover this underlying force or principle would be to arrive at the Theory of Everything since, at a glance, it would show the single underlying cause for every observation, belief, and theory in science today. Such a unified understanding is expected to transform the patchwork of separat e abstract theories in Standard Theory into a much simpler, coherent whole that shows a true physical explanation for everything, sparking a scientific revolution. The new theory discussed throughout these chapters suggests that while this vision is the proper intuition, there are several reasons why success has eluded us so far. First, since we obviously lack the deeper understanding that we are seeking, we cannot be certain we have properly identified the fundamental forces of nature. If, for example, our theory of Electric Charge is an imperfect model of the true underlying principle behind many of our observations, then our current model of proton behavior as posi tively charged particles that always repel each other may not be an accurate description of the nucleus of an atom. Instead, it may be perfectly natural for protons to cluster together when in the nucleus of an atom, according to an undiscovered principle in nature that may have been misunderstood and represented as a "positive electric charge" upon protons. That is, in many situations protons may behave as if they literally possess our concept of a "positive charge," but th is behavior could also arise from a very different principle - one that causes them to naturally cluster together when in an atomic nucleus. In that case, the concept of a "Strong Nuclear Force" keeping the nucleus from flying apart would be a completely unnecessary fabrication, and our attempts to find a unifying theory would be based in part on a force that doesn't even exist. Our current goal of unifying these four forces may be based on such flawed assumptions from the st art. Secondly, much of our current and largely mathematical approach to finding a unifying theory may be straying from the original spirit and purpose of the quest. The goal of a new and deep physical understanding of our universe may be in danger of merely becoming an exercise in mathematical manipulation of our current equations. Since arrival at this deep physical understanding is expected to yield a common mathematical framework for all the forces of nature, it is often assumed that if we simply pursue this mathematical end result directly - using our current models - we will achieve this deeper understanding. However, this approach may be unsound since it assumes we have correctly identified the fundamental forces of nature and simply need to rearrange our mathematical models. Yet, if this turns out to be an incorrect assumption, then such an approach would only achieve a largely meaningless mathematical link between flawed models of the physical world. This approac h also risks trivializing our search for dee per physical understanding into an attempt to achieve a mere mathematical goal, bringing no deeper meaning. We may expect mathematically unified models to emerge once we achieve a deep physical understanding of our universe, but this does not necessarily mean this deep physical understanding will emerge by mathematically unifying our current models. It is possible that this approach may provide some useful insights, but it may also result in little more than contrived mathematical relationshi ps between esse ntially the same equations modeling the same limited physical understanding we have today. For the reasons mentioned above, the discussions of this new "theory of everything" in the coming chapters do not strictly follow the format of a mathematical unification of the "four fundamental forces" in nature. In fact, there is very little math and only loose references to these forces amidst a broad and rich discussion of science in clear physical and common-sense terms. The discussions do, however, begin with the first of these forces - gravity - showing the numerous problems with our current gravita tional beliefs, and leading to an introduction of the new unifying principle behind a new theory of gravity that resolves these problems. Once this new principle is established, it does indeed ripple through the rest of Standard Theory in the chapters that follow, not only redefining our concept of the "four fundamental forces," but redefining the complete patchwork of theories in science today in clear physical terms. The Trouble with Gravity Newton's Theory of Gravity is undoubtedly one of the most universally recognized and accepted theories in all of science. It has become so deeply ingrained in our thinking and our science over the centuries that this theory has largely become synonymous with the very phenomenon of gravity itself. It is almost inconceivable today to separate our everyday experience of gravity from Newton's proposal of an attracting force emanating from all matter; yet, as shown in the following discussions, Newton's theory a ctually contains many unexplained mysteries and scientifically impossible claims. Such problems should prevent any new theory from becoming widely accepted as fact, leaving it only with the status of a proposal or hypothesis; however, the compelling nature of Newton's proposal combined with the lack of a more viable theory has meant that it has largely escaped such scrutiny. ? Newton's theory of gravity does not explain why objects attract one another; it simply models this observation. ? There is no known power source supporting the gravitational field that Newton claims to be emanating from our planet and from all objects. ? Despite the ongoing energy expended by Earth's gravity to hold objects down and the moon in orbit, this energy never diminishes in strength or drains a power source - in violation of one of our most fundamental laws of physics: the Law of Conservation of Energy. ? These mysteries and violations are overlooked today because of a flawed explanation that arises from the improper use of an equation known as the Work Function. ? Every effect explained by Newton's theory of gravity today is accurately modeled by non-gravitational equations that existed even before Newton. ? Newton's gravitational force is actually an entirely redundant and superfluous concept providing no additional usefulness and having no proven existence in nature or scientific support. Newton's Error - Violations of the Laws of Physics Gravity is one of the most familiar and important phenomena in nature. Although it has always been known that something obviously causes objects to fall, it wasn't until Isaac Newton (1642-1727) that we had a clear model of this something as an attracting force emanating from all matter in a manner that is precisely describable via an equation. Newton also claimed that this very same attracting force was responsible for the orbits observed in the heavens, making our universe as comprehensible and predictabl e as a clockwork mechanism for the first time in history. This was such a monumental achievement in Newton's day that it set the stage for other models of forces described by equations in similar fashion ever since. Although today we commonly speak of such forces, it is often overlooked that modern science still has little or no solid phsical explanation for many of them. The legacy of theories and equations that compose our body of scientific knowledge today works rather well, making it easy to forget that these are largely abstract models - not solid physical explanations. Newton was the first in a long line of scientists to produce explanatory models for various classes of phenomena, which can be very compelling an d useful but cannot be fully explained in physically meaningful and scientifically viable ways even today. In fact, there was a strong undercurrent of resistance to Newton's gravitational force concept when it was introduced, since it seemed to represent an almost magical force at a time when solid rational thought was finally beginning to prevail over the mysticism and superstition of ages past. Today, largely as a result of the scientific acceptance of Newtonian gravity, we have grown accustomed to the idea of unexplained forces reaching across empty space to affect objects at a distance in some equally unexpl ained manner. We have even grown accustomed to the fact that many of these forces (gravity, magnetism, electric charge, etc.) have no known power source. However, in Newton's time such concepts were only known in stories of myth and magic. To philosophers such as René Descartes (1596-1650), it had been a long journey for society to shake off the mysticism of the past and finally enter a welcome era of solid rational thought and debate. In fact, Descartes himself had an earlier and widely accepted physical theory of orbits that claimed the planets were dragged along by an invisible material, known as the ether, which presumably swirled around the sun. Although this theory had its own problems, in this era of rationality many considered Newton's idea of a completely unexplained force acting across empty space to be an unwelcome return to the magical thinking of the past. Newton realized this fundamental problem with his theory of a gravitat ional force, and never claimed to be able to explain it. However, the compelling and rational nature of his accompanying mathematical model soon solidified the force of gravity as a physical reality and a scientific fact that continued to grow in acceptance for centuries, being the predominant theory even today. It is important to note, however, that although it is generally recognized that Newton's gravitational force lacks a proper physical explanation, the much larger issue - that it violates the laws of physics - has gone almost entirely unnoticed. This point will be clearly illustrated, beginning with a reminder of one of the most fundamental and unbreakable laws of physics - The Law of Conservation Of Energy. (Law) The Law of Conservation Of Energy Energy can neither be created nor destroyed, but merely changes from one form to another. This is one of the most fundamental and unbreakable laws of physics, serving as a test for the scientific validity of any proposed theory or invention. If a proposed theory or device either uses or produces energy it must draw on an existing power source to do so, merely transforming energy from one form to another in the process. For example, the stored chemical energy in gasoline changes to kinetic energy as it is "used up" to accelerate a vehicle. In accordance with the Law of Conservation Of Energy, the chemical energy in the gasoline does not actually vanish, but is converted into another form of energy - the kinetic energy of the vehicle's motion. Similarly, the kinetic energy of the vehicle did not simply appear out of nowhere, but was converted from an existing chemical energy source - the gasoline. Although we commonly refer to power sources being drained, what we actually mean by this is that the energy from a given power source is converted into another form o f energy elsewhere. This is the law tha t tells us perpetual motion machines are impossible since they are considered to be devices capable of producing or expending energy continually without draining a power source. There is no such thing as "energy for free" in our science. Free energy devices violate our most elementary laws of physics. Also noteworthy, once it was realized that energy (denoted by the symbol E) and matter (denoted by m for mass) can change form back and forth, modeled by Einstein's famous equation E=mc2, the Law of Conservation Of Energy included matter as one of the energy forms. The explosion of an atomic bomb, for example, does not actually create the enormous amount of energy in its explosion, but is considered to release it by converting its original core of matter into energy. Therefore, in all things the Law of Cons ervation Of Energy must be upheld. (Violation) Newton's Gravitational Force Violates the Law of Conservation Of Energy There is nothing in Newton's gravitational theory stating that the force of gravity weakens as it expends energy. The mass of the moon exceeds one percent of the Earth's mass and would fly past the Earth and off into space if not forcefully constrained by gravity to circle the Earth, according to Newton's theory. Yet this tremendous continual effort expended by Earth's gravitational field is not considered to diminish the strength of this field at all - millennium after millennium. Returning to the vehicle analogy, when a car increases its speed it is said to accelerate, which is only possible by drawing on a power source, converting its energy into the car's increased speed or kinetic energy. Turning the vehicle in a circle is another form of speed change or acceleration, involving a constant, forced change from its natural straight-line direction of travel. This continuously forced circular direction change is known as centripetal acceleration, and also requires energy to maintain t his constant diversion from the natural straight-line path of objects. Likewise, the natural forward momentum of the moon would carry it away from our planet and off into space in a straight line if gravity were not forcefully pulling it into a circular orbit moment by moment. Yet this tremendous energy expenditure is not balanced by a conversion of energy from any known power source. This is a creation of energy from nothing - energy for free - rather than a conversio n of energy from one form (a power sour ce) to another (circular centripetal acceleration). This situation is a clear violation the Law of Conservation Of Energy. Gravity also forcefully holds down all objects on the surface of our planet, which would drift off into space otherwise. In fact, the pull of gravity holds our very planet together, creating tremendous crushing forces within the center of the Earth. This has been going on for well over 4 billion years, yet no known power source is being drawn upon to support this tremendous ongoing energy expenditure. This mystery is further deepened when we consider that not only is there no drainage of energy from a power source to support the effort expended by the gravitational force, but in fact there is no power source at all. A gravitational force is considered to emanate from within each atom of matter, adding up to the tremendous overall gravity of the Earth, yet we still have no explanation for its endless power source despite having created detailed atomic theories - and even having split the atom. This is a t extbook case of an impossible free energy device. This discussion naturally raises the question of why such a fundamental violation of our laws of physics doesn't generate intense scientific concern, curiosity, and investigation. Why is Newtonian gravitational theory simply accepted and its mysteries left uninvestigated? This question brings a curious mixture of responses. One answer is that science has responded to these concerns by accepting a very different explanation of gravity proposed by Albert Einstein (1879-1955) known as General Relativity Theory , which will be explored further in later discussions. However, Einstein's theory offers no solutions to these problems either. In fact, these violations are not generally acknowledged as the reasons for accepting Einstein's alternate theory of gravity, nor are these violations even generally acknowledged at all today. Perhaps more curious is the fact that even though General Relativity Theory is generally accepted in academic circles as the proper description of gravity, it is not widely taught or used by engineers and physicists - usually being reserved for optional or advanced study, and mostly for rare and exotic applications. Most university science and engineering graduates know little or nothing about Einstein's theory of gravity despite the fact that it is presumably the true explanation of this phenomenon, and it is not generally used in our space programs. Newton's concept of gravity is by far the main gravitational theory used in space missions today, despite the fact that there was apparently good reason to accept Einstein's quite different theory of gravity into our science. All of this further deepens the mystery surrounding gravitational theory today, so let's take a closer look at these issues starting with the currently unrecognized law violations in Newtonian theory. The serious law violations and mysteries found in Newtonian gravitational theory have just been clearly pointed out in reference to one of our most fundamental laws of physics, yet science does not generally recognize these violations. How can this be? Why might those who are the most highly educated in physics be the least likely to acknowledge these mysteries and violations? The answer is that when Newton's theory of gravity is taught, it is usually accompanied by further instruction on how to resolve the se mysteries and violations by referring to an equation called the Work Function. Although it will be shown shortly that this is a fatally flawed explanation attempt that gives a false sense of closure on these issues, this fact is overlooked by our educational institutions today since there is no other explanation for Newtonian gravity. Therefore, all properly educated scientists have firmly learned the standard (though erroneous) logical techniques that have been taught for generations to provide ready an swers for the mysteries and violations of Newtonian gravity. This leads to the curious fact that, on the one hand, science found it necessary to search for and accept such alternate gravitational theories as Einstein's General Relativity Theory, while on the other hand, Newtonian gravity is still widely accepted by scientists. This makes the Work Function an important pivotal element in this whole mystery, and therefore worthy of a closer look." --------------------- The continuation of this is in the "work function" stuff shared in earlier thread. One can email this author Mark Mccutcheon to get the whole of first chapter. His web site ([Only registered users see links. ]) also mentions many things so try to check it out too. Let's scrutinize his stuff and see how he went wrong in his analysis of everything (if that's the case). He can learn as well as others. c |

Only if *humans* try to move it with their muscular power, work is spent. That's because human muscles aren't fixed - they constantly move around a bit, change between "pull" and "not pull" (sorry if this seems vague - IANA biologist). Only because of this feature of human anatomy, work has to be used. And that's right, as long as you don't consider what's going on in the muscles, or if you don't use muscles at all. Right. Essentially right. What the author is missing is the stuff about the working of human muscles. For example, shells have other muscles - if humans would use such muscles, they wouldn't get exhausted by trying to push the object! Right. Garbage in, garbage out. The author displays only his own ignorance here. Complete nonsense. [snip lots - I don't think the rest is worth commenting on, after this simple elementary error] I hope my explanation satisfied you. Again, if we had muscles like the ones in shells, no work would be required when one tries lifting a 10,000 ton car! Bye, Bjoern |

| cinquirer wrote: Did you understand the explanation, cinquirer? Well, today one should say "the attraction between all energies" or "the forces caused by curved spacetime" or something like that. That's not a fundamental force, that's the residual force of the strong (color) force between the quarks. Well, they do. This can be seen from the Weizsaecker formula for binding energies. There is no "theory of Electric Charge". BTW, this theory makes predictions which are consistent with experimental results. And again wrong. The weak force doesn't act only in or on nuclei. Wrong, see above. The strong nuclear force isn't believed to be fundamental. That's a hope, not a belief, I would say. Obviously right. But what he neglects to consider is that the Standard Model of particle physics is one of the best tested theories in physics ever, so we can be quite confident that we have understood these forces quite well. Sorry, I don't understand what he tries to say here - that protons have a property which we interpret as positive charge, but which is nevertheless responsible for holding protons together in the nucleus? This makes no sense at all! Err, and the idea that in the nucleus, the property which we interpret as positive charge acts somehow to hold the protons together isn't a "completely unnecessary fabrication"? Essentially he says that at short distances, the electromagnetic force acts completely different than at large distances. This is nonsense - lots of experiments have investigated already how the electromagnetic force acts at *very* short distances, much shorter than the diameter of a nucleus, and nothing like this was found. "may". BFD. Then why do the predictions of the SM agree so well with experimental results? [snip rest; sorry, it's a complete waste of time to read this drivel] He went wrong at lots of places - for some, see above. If you would learn some elementary physics, you would see this yourself! No. Crackpots are in general unteachable. (I'm speaking from experience) Bye, Bjoern |
