Read it. Do the problems. Then come back. [EL] Most probably he did, and this time he is back. But to your disappointment he came back disgusted, which is not exactly what you were hoping for. If you just want to spout nonsense, its plainly obvious that you have taken to attempt to learn about what you are denouncing, which makes it easy to ridicule you. If you make an honest attempt to learn the material, and then spout nonsense, it may be more interesting. Shaun [EL] I agree that he did not present mathematical arguments, which is very consistent an attitude of one who resents the theory. What you need is a dirty devil called EL to **** your mind out and then put it back in rational order to regain your ****ing sanity. Of course "time dilation" as a wording would best be the name of a quantity which is the inverse of velocity. The magnitude of velocity reflects the concept of "faster" in direct proportionality, and the magnitude of "time dilation (the inverse of velocity) reflects the concept of "slower". The "er" suffix is what makes the issue a relativistic issue because sentient healthy scientists must produce a complete sentence describing "A is faster than B therefore B is slower than A, when their velocities are measured with respect to C as the distance travelled by each over a unit of invariant common time interval, and their dilations are measured with respect to a C-D invariant interval unit of space as the time interval magnitude they need to traverse that distance". I have no problem accepting good techniques and formulations in any theory of relativity beginning with Kepler onwards. Unlike Robert, I would not reject ALL of SR and GR because of some contradictions and confused ridiculous claims made by either, but rather put it into a distillation column and extract the pure water while discarding the ****. Robert does have a good point, which you failed to address like a scientist would do. Usenet has two diametrically opposite types of lunatics. One of the two types is really ignorant and post ridiculous nincompoop. Another type, and please pay attention, is a pseudo-scientist and a pretender who knows how to cut and past from the mainstream dogmatic text and only wishes to look like he was the defender of the true science. That type has no argument either and his post is empty and useless. To give an example, just read your post to which I am replying. EL |

[EL]
I applause your responsible response Kees. You replied like a true scientist who understands relativity. Robert made one fundamental mistake and that is the title of the thread. The mistake he points out is not that of SR but that of ignorant pseudo scientists who pretend to know what they talk about. Robert seems to have the Twin Paradox in mind, which we both know to be waffled nincompoop because SR does not handle the accelerated frames required to reach the velocities of travel. Hence, the conclusion of one returning younger than the other is a joke or a cute catch at best. I am sure that Professor Einstein never meant The Twin Paradox literally but he was trying to stick out his tongue like the cute witty clown he was to explain relativistic effects on remote observations mediated by light. You also pointed out in your numbered points, that Robert was correct (partly). I have to conclude that SR and its teachers seem to have failed miserably to teach what they know to be a fact. That is why Robert posts such a post, because if you and others did not fail in that mission this post would have never been posted. So let us not be too hard on honest knowledge seekers and try to find our defects and why we fail to explain relativity properly. The problem is that the scientific community is littered with arseholes that mix jokes and science and one may not be clever enough to distinguish if they were kidding or teaching science. Time dilation would be much easier to explain if we taught that it is the inverse of velocity. Period. EL "Kees Roos" wrote in message ... "Robert Calvert" schreef in bericht ... Answer a few simple questions if you can: Two clocks (a and b) are placed 100 light hours apart and are both synchronized. Then the clocks are accelerated toward each other at the same time and at the same rate until they both meet. Then they stop at the same time and at the same rate of deceleration. Will we find that clock (a) has recorded more elapsed time than clock (b)? Or will we find that clock (b) has recorded more elapsed time than clock (a)? If either of these first two scenarios are correct, then I would have to wonder what sort of magical spell would favor one clock over the other. If both clocks read the same elapsed time, then we would have to conclude that relative motion cannot produce time dilation since both clocks were obviously in motion relative to each other during the experiment. Why don't you just try to calculate what SR predicts for the scenario you present? If you would have done so instead of just guessing, you would have seen that SR predicts that: 1: The elapsed time during the experiment for both clocks (a) and (b) will be the same, so your third guess is correct. 2: Both clocks (a)and (b) will observe time dilated in the other's frame, as well as in the original stationary frame. So, your conclusion that relative motion cannot produce time dilation in SR is incorrect. I challenge you to make this calculation and see that the rest of your article is rambling about a conclusion you reach on results which are not SR's. Hint: Simplify your scenario by assuming instant acceleration and calculate when and where each event in your experiment happens relative to each of your two clocks and relative to the original stationary frame. Acceleration which is not instantaneous will yield the same qualitative results, but the calculation will be more complicated. You don't show that SR is dead, just that you don't understand it.

"Robert Calvert" wrote in message ... snip I can't help but notice that none of you knuckleheads have answered my questions in a logically satisfactory way. All I've seen so far from you Relativity worshipers are flames and non sequiturs. Ask an illogical question; get an illogical answer. What I posted was neither a flame nor a non-sequitur. I simply observed that your question has a premise that has no been demonstrated to be true. GR proves to us that clocks cannot be "synchronized." You must first *disprove* that theorem before your questions have any basis in logical discussion. Extraordinary claims require extraordinary evidence. You are the one claiming (against the data of GR) that clocks can be synchronized. Prove it. We are waiting. Tom Davidson Richmond, VA |

"Len Gaasenbeek" wrote in message ... For an explanation where Special Relativity went wrong also see the first and last of my Selected Papers titled: "Helical Particle Waves", and "Time Dilation: Fact or Fiction". Interesting theory. But instead of light adjusting it's speed in rout, I think that, when a photon leaves it's source, it's already traveling at c relative to whatever object is destined to absorb it. We may actually live in a universe in which photons whiz past us at many different speeds. [EL] Past us! We neither live in vacuum nor in solid glass. Indeed light propagates in many speeds of (c/n), where "n" is the refractive index and n = 1 (reads equal to or greater than ONE) But it may also be the case that we'll never be able to capture any that are moving faster or slower than c. [EL] Capture! We do capture electromagnetic waves moving at (c/n) all the time empirically, so getting poetic is not science Robert. This theory is based on the idea (I don't know if it's true or not) that light never leaves it's source without first having an "electrical connection" with it's destination. Robert [EL] Wrong, light does not "create" the "connection", which is rather there all the time. Vacuum is nothing else but an electromagnetic medium that pervades spacetime continuum. The source, which might be 15 billion light years away, may very well disappear long before the destination have emerged from chaos into order or simply come into existence. We must satisfy the rules of logic along with respecting our arbitrated standards or science would fail miserably. What remain are the technicality of procedure and the quantitative formulation of relations that we need to establish into a discipline. If "scientific theory" had no applied merits then its destiny is the garbage bin. EL |

I wouldn't exactly go so far as to say that SR is all bogus just because of the twin paradox. But when you find a group of people who make a claim that you know to be logically inconsistent, you can't help but question their competence and honesty. And you can't help but wonder if they're just telling you a half truth or if they're pushing a complete and total fraud. I can imagine that certain aspects of relativity are valid. But it seems to me that if anybody conjured up an SR like theory that could resolved the twin paradox, it would have to be so radically different that I don't think it would be entirely accurate to call it SR. This is why I believe that SR is dead. Robert |

Tom Davidson Richmond, VA Tom, the universe is a continuity without a time dimension, thus concurrent existence is correct. In that concurrent existence changes of state take place. Those changes of state can take place faster or slower depending on velocity. That is really all SR tells you. You don't know squat about what SR tells us.

Alice gets her phone and calls Bob. “Bob! There is something wrong with your clock! You synchronized it with mine, and now 333 nanoseconds slow.” Bob looks back at Alice’s clock. Bob tells Alice, “No, Alice. It is *your* clock that is 333 nanoseconds slow!” Alice tells Bob, “This is too confusing. Lets go talk to Cosmo. He has a clock just like ours, and he knows about physics.” Alice and Bob take their clocks over to Cosmo’s House. Cosmo lives 100 meters away from Bob and 100 meters away from Alice. “Help Us, Cosmo!”, they plead. “There is something wrong with our clocks, or with the fabric of space and time!” Cosmo makes sure all three clocks read exactly the same time. Run, clocks, run. Cosmo then sends Alice and Bob straight home, but he tells Alice to run and Bob to go slowly. Alice takes 30 seconds to run home. Bob takes 5 minutes to get home. Cosmo then sets up a conference call with Alice and Bob. “Alice, what do you see when you look at our clocks?” Cosmo asks. Alice replies, “Why, BOTH of you have clocks that are 333 nanoseconds behind mine. Does that mean that both of you have slow clocks, or that my clock is fast?” “Bob, what do you see when you look at our clocks?” Cosmo asks. Bob replies, “I see that you and Alice have clocks that are running 333 nanoseconds behind my clock! It looks to me like my clock is the fast one. But Alice and I can’t each have a clock that is faster than the other clock!” Cosmo explains, “No. You can’t. I see that both your clock and Alice’s clock show exactly the same time, and that time is 333 nanoseconds behind the time my clock shows.” “Now, my clock didn’t go anywhere, and nothing happened to it. We can call it the ‘Cosmo-logical’ clock. Alice, you moved your clock 100 meters in a very short time, and it looks to me like it lost 333 nanoseconds against the Cosmo-logical clock. Bob, you moved your clock 100 meters in a much longer time, and it looks to me like it also lost 333 nanoseconds the Cosmo-logical clock. “ “How FAST you moved your clock has no effect on the result. Alice, your clock lost 333 nanoseconds in 30 seconds while you were moving away from me. It seemed to me it was only running 99.999999 percent as fast as it should, but when you stopped moving away from me it appeared to resume running at normal speed.” “Bob, your clock lost 333 nanoseconds in 300 seconds while you were moving away from me. It seemed to me it was only running 99.9999999 percent as fast as it should, but when you stopped moving away from me your clock also appeared to resume running at normal speed.” “I’ll bet neither of you noticed a thing.” Alice answers “No, Cosmo, we didn’t notice.” Bob adds “What *should* we have noticed, Cosmo?” Cosmo tell them “If you had been watching my clock instead of watching where you were going, you both would have seen my clock seem to slow down by as much as I noticed your clocks slowing down. That would have been dangerous, however.” Alice says, “But I see that your Cosmological clock and Bob’s clock show exactly the same time. How can that be?” Cosmo answers, “How fast you were moving away from me determined how fast your clocks seemed to be losing time. How much time your clocks seemed to lose was determined by how far you went away from me. Since you both went the same distance, you both seemed to lose the same amount of time.” Bob says, “Cosmo, I hear you using the word “seem” a lot. What are you trying to say, or to not say?” “That is very observant of you, Bob,” Cosmo nods. “I say ‘seem’ because what is really going on is not always what seems to be going on, and *how* we see the world is limited by the *way* we see the world.” “First, let me say that the laws of physics are exactly the same for me and for each of you, whether you are moving or not. Everything in the universe has to follow the same laws. In physics that is called the ‘Principle of Relativity.’ It amounts to saying that everything that you see and know about the universe is relative to your personal point of view. Somebody else, watching from somewhere else, may see things that you do a little differently from the way you see them, but you will never see a change in the laws of physics.” “We are using light to see each other’s clocks. Light travels at a constant speed called ‘the speed of light.’ That speed is finite. Light travels at about 300,000 kilometers per second. It takes 333 nanoseconds for light to get from me to either of you. It also takes that long for light to get from either of you to the other.” “What I see on your clocks is not what is actually there at the instant I’m looking at it, but only what WAS there at the instant the light left your clocks. That light then takes its own sweet 333 nanoseconds to get to me and let me know what *was* going on with you. That is why your clocks seem to me to be running 333 nanoseconds behind.
