James wrote: You claimed LET is superior to SR because it can explain WHY the local measurement for light is always c. To do this you must invoke an ether. An ether which you claim is real. O'Barr (globarr) comments: Might you also be able to see some of your own biases? The ether is not used just to explain why c is a measured constant. The ether is first of all used so that the speed of light could have a fixed absolute velocity at all points in space. There does have to be something everywhere in space to cause this to happen. Otherwise, the velocity of light could not be independent of its sources, etc. And second: The ether is used to cause the rates of clocks to vary with their velocities, at all points in space. And this is not just an assumption. The rate of a light clock will produce the exact math function that is required, exactly, automatically! And so if one clock works this way, why not all clocks? We have never seen one clock be different than another as far as their basic functions work. There does have to be something, at all points in space, to cause these things to happen. And third, there has to be something to cause the length of rulers to change with their velocities. And again, this is not just an assumption! We can take what is known about electro-magnetic properties, and use the diameter of an equal potential sphere to represent the changes in the lengths of rulers, and get the exact math function needed. And there does have to be something everywhere in space to cause these effects. And then 4th: We can show that the combined effects, of a constant absolute velocity of light, with the changes in rates of clocks as automatically seen in a light clock, and the changes in the lengths of rulers as automatically found in an equal potential sphere, along with the proper syncing of such clocks, automatically resulting in a constant measurement of the speed of light. And thus, at this point, we have SR math, when we add the correct sync to the clocks being used. And you want to call the ether as just a way to make c a constant? All these things are a beauty to behold, 10 times more beauty than what you have in SR, and all these independent but correlated effects that naturally result in SR math is in itself a strong suggestion that it is all real and is the way it is! Everyone of these things are found to exist! So yes, the ether is used to do what you say, but it is not just a word. It is not just a word used to give an explanation. It is a most complete science, with full justification for saying what the rates of clocks would be, for saying what the lengths of rulers should be, and in explaining then why we can measure the speed of light to be a constant. You made it sound as if it was just an excuse. It is a science, and you should be more honest in at least saying as much as we do know about this science! Obviously, we need to know more. But we do know much, and the ether is not, as I said, just a word or just an excuse! James wrote: Every attempt to detect a 'real' ether has ended in failure. Gerald L. O'Barr wrote: And this is all so incorrect! Can you tell me one experiment where LET ether was tried to be detected and it was not detected? You are saying things here not because of any science that is known or exists, but you are saying this to put false concepts into people's minds! I know what the ether is, and you will never be able to confine it, to box it up, to weight it, to do anything with it at all. And there is nothing in LET that says anything like these things are possible! So your thoughts up above are unscientific, and I expect to hear from you a retraction! James wrote: "If you use a false premis [the ether exists in nature] to explain WHY something 'IS' [why the local speed of light is always measured to be c] your explanation is false." Your conclusion that the 'ether exists in nature' because it has never been shown to not exist IS unscientific. Fools logic. O'Barr comments: Yes, if a false premise were used, any explanation based upon a false premise would normally be assumed to be false. The question, however, that is being addressed, is the premise false or not? To determine if a premise or a theory is false or not, is the purpose of science, and scientific testing. So what test has been made to falsify LET? Until this science has been accomplished, then scientists should not go around and say that there cannot be an ether. It is not just this, but the ether, producing the exact same math as SR, means that the LET ether is just as well established, scientifically, as SR. In fact, considering all the other things that LET can do that SR cannot do, such as provide us real physical understanding of what is really happening, and doing all this in a simpler 3-D setting, we find that LET is far superior to SR. Also adding to LET favor, LET provides for us full and complete causes and effects, it is a doable approach, with the simplest of kinematics, with no breaks in symmetry, no jumps in time, with no physically impossible 4-D spacetime continuums, etc. In fact, in every way possible, LET is completely superior to SR. The only advantage that SR has is that it, being just math, might be easier to use, and it might have one less step in deriving it. But LET does not prevent anyone from using SR math, since it is the same. So there really is not one thing lost by using LET. It is all gain! Thanks for reading. Gerald L. O'Barr |

Thus if you always assume the ether frame to perform your calculations then you will be able to derive the lorentz transform from Lorentz premises of: Galilean relativity with absolute simultaneity, and physical resync of rulers and clocks. The moment that you set K in motion wrt the ether frame all bets are off. This is what the gedanken proves, that is, that the lorentz transform forbids an absolute ether. This is something that Einstein saw , that he failed to formalize a proof of the difference between his theory and Lorentz doesn't change a thing. I see that you won't deliver the goods... And why should I continually repeat what I've already related to you. "There are infinitely many ethers". I don't recall that. And in what article did Einstein state that? I like to see the context.

For if no particular state of motion can be ascribed to the ether, there does not seem to be any ground for introducing it as an entity of a special sort alongside of space. But the physicists were still far removed form such a way of thinking; space was still, for them, a rigid, homogenous something, incapable of changing or assuming various states." [...]"But it must now be remembered that there is and infinite number of spaces, which are in motion with respect to each other. The concept of space as something existing objectively and independent of things belongs to pre-scientific thought, but not so the idea of the existence of an infinite number of spaces in motion relatively to each other. This latter idea is indeed logically unavoidable, but is far from having played a considerable role even in scientific thought." The above two passages, when taken together in their common context, yield the unavoidable conclusion that "There is an infinite number of ethers, which are in motion with respect to each other". IOW, Einstein's double statement "there is an infinite number of spaces" and "space and ether are just different terms for the same thing" is logically equivalent to "there is an infinite number of ethers(spaces)". Though he didn't actually write down this statement, he certainly did make that statement loud and clear, it being the heart and soul of both of the articles from which these passages were extracted. I suppose the reason that he never stated it using the term "ethers" was that the word "spaces" was less ambiguous, more exact, and besides the use of the word "ether" in that statement might have been wrongly assumed without further clarification to indicate the "luminiferous ether", a concept that he was in fact attempting to discount with these two arguments. Richard Perry This was derived from the transform. IOW Einstein was stating outright that the lorentz transform is contradictory to the premise of an absolute ether. He thought so little of Lorentz's view that he purposely avoided the subject, not even making reference to him in his papers. It seems to have never occurred to you to track down the source of his disagreement. Richard Perry Harald |

Subsequently it is only a theoretical construct, much the same as 'curved spacetime'. LET doesn't explain WHY we observe physical phenomena any more than any other theoretical model. It may be useful for making theoretical predictions which can be tested empirically but it doesn't explain WHY the local speed of light is always measured to be c [or any of the other WHY's for physical phenomena you've mentioned]. Now maybe if the ether is actually observed as physical phenomena...? You might actually have a real argument. James |

Still, as Einstein himself stated, it's the logical consequence of his own interpretation. Thanks for the citation. Harald Richard Perry This was derived from the transform.

Those that were suppose to see these comments did see them.) Gerald L. O'Barr (globarr) wrote: . . . Thanks for correcting me in such a kind way! more deletes by O'Barr James wrote: If LET makes the exact same predictions, wrt physical phenomena, that SR makes then LET hasn't been falsified as a theory. Gerald L. O'Barr comments: This is correct. In terms of the math, SR and LET have the identical math, and thus their math predicts the exact same math answers. The interpretations of what the answers actually mean are, of course, different. But having the correct answers is the same. Thus, on a scientific basis, you cannot falsify LET without at the same time falsifying SR. And you cannot support SR without also supporting LET. This is one of the most interesting facts of science that has ever existed, that two theories that appear to be so opposite, are really the same theory! And yet the SR experts will not allow such facts to be presented and discussed and understood! As said, the problem comes in that SR experts are not generally willing to agree to these things. They do not allow such a statement to be made in the FAQ. They do not address this fact in the literature, although one reference was given where such a statement was made at one time. So it is unscientific to teach people that SR proves that there cannot be an absolute reference frame. The fact that it can be ignored is not proof that it is not there. And it is unscientific for people to say there is no ether. What tests have shown is that there is, so far, no ether that produces the effects of a mechanical wind pressure that can be separated from gravity or electrical effects, etc. And there is no absolute space where rulers and clocks are unaffected by their motions in space. These things can be shown. But the ether used in LET cannot be disproved to exist, and will never be disproved as long as SR is correct. James wrote: The discussion wasn't whether LET has been falsified as a theory. It was whether LET is superior to SR for doing science. Gerald L. O'Barr comments: Obviously, it might depend on what research you are doing. If you are doing SR research, you are not likely to be doing much to find an ether. LET would be superior if your research was to find the ether, or properties of the ether, etc. In those research areas where you are only testing the math results, and trying to find limits, it does not matter which theory you might use. But to know where to really expect your actual limits, then LET might give you a better understanding of where these limits might be. What you need to know is that using LET will never hurt your efforts. All the math and math symmetries are there in LET, everything you have in SR is contained in LET or in LET math. And the physical base to LET can give you better limitations to guide you than SR alone. James wrote: Your argument is LET explains WHY certain physical phenomena [I won't list them] is observed. To do this you must invoke the ether but the ether has never been observed as physical phenomena. Gerald L. O'Barr comments: Your choices of words seem so interesting. The ether was not observed as it was expected to be observed. Is this what you wanted to say? We did not find the ether blowing things over, or mechanically moving things around. Is this what you wanted to say? But the effects of the ether are seen everywhere! Every photon that moves away from a source at the identical velocity, no matter at what changes in velocity of the source moves, is an effect of the ether that is directly observed at all points in free space. The fact that moving clocks slow down, at the specific rate of a light clock; and the fact that lengths change, at the exact rate calculated in LET; makes the effects of the ether to be obvious. And the measuring of the velocity of light to be c is a direct effect of the ether. Thus, the effects of the ether are everywhere, exactly as expected and demanded by the theory! It cannot be seen more directly than this! James wrote: Subsequently it is only a theoretical construct, much the same as 'curved spacetime'. Gerald L. O'Barr comments: I am sorry! This is not true! LET is a physical theory, where the physical acts of physical objects are scientifically specified, and then the results of these acts are analyzed and properly put together to form a math relationship. Thus, when the math is finally achieved, the physical reasons why the math works is clearly and specifically given, and it is the physical base that then defines the math, gives or established the limits to the math, and allows anyone to understand what is physically happening so that the math answers can be correct applied and understood. In SR, you start only with math (c is a math constant, and math equations must maintain a common form), and you end with math. At no time can you really tell what really physically happens, and what real limits might exist in the math, or what the math really means, other than it is what will be measured if you use certain tools in a certain way. James wrote: ... LET doesn't explain WHY we observe physical phenomena any more than any other theoretical model. O'Barr comments: It is true that for all theories we have so far, all have an end to their explanations, and a point where further explanations will be necessary. But when you are comparing different theories, it is unimportant that all theories have such a common end. What is important, is which theory takes us the furtherest along the way! LET is a deeper based theory than SR, providing to use one step lower into our reality than SR. And thus, LET is superior to SR! James wrote: It may be useful for making theoretical predictions which can be tested empirically but it doesn't explain WHY the local speed of light is always measured to be c [or any of the other WHY's for physical phenomena you've mentioned]. O'Barr comments: The very reason why anyone believes in the ether is because it does tell us why c is a measured constant. First of all, it tells us how and why c is always an absolute constant, something that must be in order that all these correlations can exist, and then LET explains step by step why this absolute constant can be measured to be a constant in different moving inertial frames. How did you miss all this? James wrote: Now maybe if the ether is actually observed as physical phenomena...? You might actually have a real argument. O'Barr comments: Well, certainly, if you could put some ether into a bottle, and compress it, and weigh it, and check its color, we would not be having this argument. But you are being unscientific in this point unless by theory you show that LET requires its ether to be physically observed in some way, and then you can show that it is not seen the way the theory says. Until you do this, you are being unscientific. The ether and/or its direct effects are seen in every way required by the theory. And thus it is unscientific not to accept the ether as being a viable theory. QED! And you are not unscientific, are you? Thanks for reading. Gerald L. O'Barr + Remove 3 dots for e-mail. |

You only think it is impossible based on preconception. That's what is meant with "paradox"... It is a verifiable fact of nature. FYI, O'Barr fully agrees with what will be observed. Here's another one for you: it's an observable fact of nature that when you look at me at a distance through a magnifying flass, you observe me as upside down and shrunk. But it's not observable that I *really* shrunk, nor does it make sense to say so! ;-) wrote in message oups.com... I did not prove your point. Your point is from your perspective 'it is impossible'. There is no ether [this is a fact of nature]. Actually, since the magnifying glass here is causal as is the ether, "there is no ether" is also certainly *not* a "fact of nature"... If you use a false premis to explain why something 'is' your explanation is false. If you postulate something [ether] to construct a theory which makes verifiable predictions then that can become a useful scientific tool. Now lets ask the question which theory is actually used in scientific research, SR or LET? If LET was more useful than SR it would be used [regardless of what Harald thinks]. Assuming that with "LET" you mean Lorentz' explanation of SRT, what do you think is the difference for use? Cheers, Harald |

And yet the SR experts will not allow such facts to be presented and discussed and understood! As said, the problem comes in that SR experts are not generally willing to agree to these things. They do not allow such a statement to be made in the FAQ. They do not address this fact in the literature, although one reference was given where such a statement was made at one time. So it is unscientific to teach people that SR proves that there cannot be an absolute reference frame. The fact that it can be ignored is not proof that it is not there. And it is unscientific for people to say there is no ether. What tests have shown is that there is, so far, no ether that produces the effects of a mechanical wind pressure that can be separated from gravity or electrical effects, etc. And there is no absolute space where rulers and clocks are unaffected by their motions in space. These things can be shown. But the ether used in LET cannot be disproved to exist, and will never be disproved as long as SR is correct. Within the context of relativity, SR and GR, there are no absolute reference frames. So when teaching the theory it makes sense to state this. What tests have been conducted which show that the ether, and or an absolute frame of reference exist? James wrote: The discussion wasn't whether LET has been falsified as a theory. It was whether LET is superior to SR for doing science. Gerald L. O'Barr comments: Obviously, it might depend on what research you are doing. If you are doing SR research, you are not likely to be doing much to find an ether. LET would be superior if your research was to find the ether, or properties of the ether, etc. In those research areas where you are only testing the math results, and trying to find limits, it does not matter which theory you might use. But to know where to really expect your actual limits, then LET might give you a better understanding of where these limits might be. What you need to know is that using LET will never hurt your efforts. All the math and math symmetries are there in LET, everything you have in SR is contained in LET or in LET math. And the physical base to LET can give you better limitations to guide you than SR alone. James wrote: Your argument is LET explains WHY certain physical phenomena [I won't list them] is observed. To do this you must invoke the ether but the ether has never been observed as physical phenomena. Gerald L. O'Barr comments: Your choices of words seem so interesting. The ether was not observed as it was expected to be observed. Is this what you wanted to say? What I wanted to say I actually wrote. Once again: Your argument for WHY certain physical phenomena occur, in nature, is because there is an ether. My argument is that you can't explain why physical phenomena occur based on a experimentally unverified theoretical construct. You can predict what will be observed but not WHY it is observed. It's obvious that we are going to have a different opinion so I'll conclude by saying its been a pleasure. Janes not find the ether blowing things over, or mechanically moving things around. Is this what you wanted to say? But the effects of the ether are seen everywhere! Every photon that moves away from a source at the identical velocity, no matter at what changes in velocity of the source moves, is an effect of the ether that is directly observed at all points in free space. The fact that moving clocks slow down, at the specific rate of a light clock; and the fact that lengths change, at the exact rate calculated in LET; makes the effects of the ether to be obvious. And the measuring of the velocity of light to be c is a direct effect of the ether. Thus, the effects of the ether are everywhere, exactly as expected and demanded by the theory! It cannot be seen more directly than this! James wrote: Subsequently it is only a theoretical construct, much the same as 'curved spacetime'. Gerald L. O'Barr comments: I am sorry! This is not true! LET is a physical theory, where the physical acts of physical objects are scientifically specified, and then the results of these acts are analyzed and properly put together to form a math relationship. Thus, when the math is finally achieved, the physical reasons why the math works is clearly and specifically given, and it is the physical base that then defines the math, gives or established the limits to the math, and allows anyone to understand what is physically happening so that the math answers can be correct applied and understood. In SR, you start only with math (c is a math constant, and math equations must maintain a common form), and you end with math. At no time can you really tell what really physically happens, and what real limits might exist in the math, or what the math really means, other than it is what will be measured if you use certain tools in a certain way. James wrote: ... LET doesn't explain WHY we observe physical phenomena any more than any other theoretical model. O'Barr comments: It is true that for all theories we have so far, all have an end to their explanations, and a point where further explanations will be necessary. But when you are comparing different theories, it is unimportant that all theories have such a common end. What is important, is which theory takes us the furtherest along the way! LET is a deeper based theory than SR, providing to use one step lower into our reality than SR. And thus, LET is superior to SR! James wrote: It may be useful for making theoretical predictions which can be tested empirically but it doesn't explain WHY the local speed of light is always measured to be c [or any of the other WHY's for physical phenomena you've mentioned]. O'Barr comments: The very reason why anyone believes in the ether is because it does tell us why c is a measured constant. First of all, it tells us how and why c is always an absolute constant, something that must be in order that all these correlations can exist, and then LET explains step by step why this absolute constant can be measured to be a constant in different moving inertial frames. How did you miss all this? James wrote: Now maybe if the ether is actually observed as physical phenomena...? You might actually have a real argument. O'Barr comments: Well, certainly, if you could put some ether into a bottle, and compress it, and weigh it, and check its color, we would not be having this argument. But you are being unscientific in this point unless by theory you show that LET requires its ether to be physically observed in some way, and then you can show that it is not seen the way the theory says. Until you do this, you are being unscientific. The ether and/or its direct effects are seen in every way required by the theory. And thus it is unscientific not to accept the ether as being a viable theory. QED! And you are not unscientific, are you? Thanks for reading. Gerald L. O'Barr + Remove 3 dots for e-mail. |

O'Barr (globarr) comments: In a limited way, every word you said above is correct. SR and GR do not directly use an absolute reference frame. And it is required that this be stated if you are going to teach these theories. But the error is in the science! All physical theories should be presented and taught as they presently stand within the known science. And a good college professor will be sure to do this, usually at the introduction of the course. And the known science includes LET. Thus, when SR and GR are taught without the correct science, where these stupid professors say such things that SR proved that all ether theories were wrong, they lie! When they say such things that SR or GR could not work if there were an absolute reference frame, they lie. And I see that you yourself have not been too careful here to say things as they should be said scientifically. Why is that? Why are you so afraid to simple say what we presently know? James wrote: What tests have been conducted which show that the ether, and or an absolute frame of reference exist? O'Barr comments: Scientifically, if every test made shows a theory makes correct predictions, within its error of margin, then these tests show that that theory is an acceptable or a correct theory. And therefore, for too many repeats here to be justified, every test that has shown SR to be correct, also affirms the correctness of there being an ether! QED! Again, why are you being so dense? Why are you unwilling to even say what any correct thinking person would say? Why are you being this way? Don't you want to be scientific? deletes by O'Barr Gerald L.

James wrote: What I wanted to say I actually wrote. Once again: Your argument for WHY certain physical phenomena occur, in nature, is because there is an ether. O'Barr comments: Ether or no ether, there is in LET the use of simple 3-D. This is no minor part to the theory. No one has to have an ether in order to have a 3-D approach, do they? And in the LET approach, there are absolute things, like an absolute rest frame. Do you really have to have an ether in order to have an absolute rest frame concept? And in the LET theory you use simple addition of velocities. Do you have to have an ether in order to have simple addition of velocities? For some reason, you seem to be unable to understand that this theory is a theory that includes real objects, to include clocks and rulers, and it includes their rates and their lengths, and the exact E&M that is know to exist. So the theory is a very deep and a very complete theory, and the ether is just one part of the theory. It helps to bring about certain important inter-relationships. But you really could remove the ether, and keep the kinematics by assumption, and get the exact same thing. The ether, as an actual medium, is there only because we are use to saying that it is there, not that its actual properties are used at all. It is the power of the kinematics that makes LET superior to SR, and you need to come to understand this problem much better if you are going to be scientific. James wrote: My argument is that you can't explain why physical phenomena occur based on a experimentally unverified theoretical construct.

O'Barr wrote: When two people are being scientific, there is little room for disagreements. That is why science is successful, there is most often only one conclusion that can be agreed upon when there is good science that is present. As was answered, LET is superior because it does answer questions that is not possible for SR to answer. LET is one level deeper than SR. Sure, LET has questions, just like SR, that it cannot yet answer. But you have no scientific right to ignore this fact that LET is able to answer deeper questions than SR. And this is all that is necessary to make LET superior to SR. There cannot be any difference of opinion on any of these issues! QED.

If you think your misunderstanding of the theory, constitutes a problem for the theory, you are mistaken. I'll translate it to you with slightly polarised words: - Almost everyone here rejects Einstein's explanation of what he called the Twin Paradox (one likely exception : Ken Tucker). Yup, thanks Harry, I think GR is needed to explain why clocks become asynchonized because a bit of relative acceleration is required. If two clocks t and s are synchronized then dt/ds = constant , and then the change in that constant is zero, d/ds (dt/ds) = 0 == synchronized What GR does is to define when d/ds (dt/ds) =/=0 == asynchronization, which requires some form of change in the relative energy of clocks t and s, which is quite simple to imagine, but somewhat difficult to write in equations. Like it's easy to imagine carrying a clock up a flight of stairs, well you guy's know... Ken |
