Tse - 20 Mar 2006 15:27 GMT "The Lorentz Transformation for Velocity"
It is recognized that Special Relativity provides the Lorentz Transformations for Length and Time and Mass between reference frames having a relative velocity. What is too often not recognized that, in so doing, it provides the transformations for all other physical quantities! These remaining transformations may be determined by applying the conventional Lorentz Transformations to accepted physical equations.
Since a velocity is equal to a length divided by the time required to traverse that length, the Lorentz Transformation for Velocity must equal the Lorentz Transformation for Length [1/(1-V^2/C^2)^0.5] divided by the Lorentz Transformation for Time [(1-V^2/C^2)^0.5]. The Lorentz Transformation for Velocity is therefore equal to 1/(1-V^2/C^2). (As incredible as it may seem, the writer has received a communication from an individual who asserts that a Lorentz Transformation for Velocity cannot be determined by dividing the Lorentz Transformation for Length divided by the Lorentz Transformation for Time even though velocity is defined as length divided by time! I suspect that this individual is a PhD who has a vested interest in maintaining the intellectual status quo. If he is a physicist he is in the wrong line of work, I understand that Walmart is hiring.)
This transformation yields a conclusion which is in conflict with the current understanding of Special Relativity. Present dogma asserts that the velocity of light is the same in all velocity reference frames. If one considers two reference frames, A and B, moving at a relativity velocity V with respect to each other, one finds that an observer in A measures the velocity of light in his own reference frame as its conventional value of C and the velocity of light in B as having been reduced by the Lorentz Transformation for Velocity. Similarly, an observer in B measures the velocity of light in his own reference frame as C and the velocity of light in A as having been reduced by the Lorentz Transformation for velocity. While superficially this may seem to be a contradiction, the difficulty vanishes when one factors in the effects of the limit on the velocity of information transfer imposed by the velocity of light.
We are forced to accept the conclusion, however, that the velocity of light changes as a result of a change in velocity and that this change in velocity is concealed by a change in the size of the units of measurement for velocity (length/time) making it appear that the velocity of light is the same in both reference frames. In terms of unchanging units of measurement, the velocity of light does differ between reference frames which differ in velocity, it only appears to be unchanged when it is measured within each reference frame. It may be stated, therefore, that Special Relativity requires that the velocity of light be a "constant" but cannot be constant between reference frames having a relative velocity. This conclusion is consistent with the Lorentz Transformation Aether Theory which asserts that our velocity with respect to the Aether is indeterminate.
However, one may derive more information from Special Relativity. Consider two velocity reference frames, for example Earth and Mars. (See http://einsteinhoax.com/cf42.gif.) A rocket is located on Earth and three identical clocks are in use. One clock is located on Earth, one is located in the rocket, and the third clock is located on Mars. The observer on Earth and the observer in the rocket report that their clocks run at the same speed and that the clock on Mars runs slower due to the relative velocity between the two locations. The observer on Mars reports that the clocks on the Earth and on the rocket run slower than his clock.
After the readings have been taken, the rocket takes off and travels to Mars and stops there. The observer on Earth notes that the speed of the clock on the rocket has slowed to the speed of the clock on Mars while the observer on Mars notes that the speed of the clock on the rocket has increased to match the speed of his own clock which is faster than the speed of the clock on the Earth. The observer on the rocket does not notice a change in the speed of his clock, but since he is familiar with Special Relativity knows that the speed of his clock has changed as a result of his observed change in velocity but that he cannot observe that change in the speed of his clock. He observes that the change in velocity of his rocket has occurred and that the speed of the clock on the Earth has appeared to slow and the speed of the clock on Mars has appeared to increase. This observation does not bother him or the other observers since all are familiar with Special Relativity.
Consider what this thought experiment has shown. It has shown that not only is it impossible to measure our velocity with respect to the Aether and hence it is impossible to assert that the Aether does not exist, It has also shown that Special Relativity requires that there be an absolute velocity reference frame (i.e.- the Aether). In the Rocket Experiment all three observers report that the speed of the clock has changed as a result of the change in the rockets velocity. The observer on Earth asserts that the speed of the clock on the rocket has slowed, the observer on Mars asserts that the speed of the clock on the rocket has increased, and the observer on the rocket asserts that the speed of his clock has changed but that he cannot observe that change. There is one item of information that all three observers agree on. The speed of the clock on the rocket changed as a result of the change in the rocket's velocity.
One event, the change in speed of the rocket, has caused the speed of the clock on the rocket to change. Since there was only one causal event, there can only be one result, the speed of the clock must actually increase or decrease, it cannot do both! In order for that conclusion to be true, there must be an absolute reference frame for velocity. The classical Aether, which cannot be proven not to exist, must exist!
Two objections have been raised to this argument. The first is that it involves acceleration and Special relativity does not include the effect of acceleration. This argument is meaningless since no acceleration occurred when observations were being made. The second argument involves the speed of communication between the Earth and Mars. This is a foolish argument since the observations were all made prior to the start and after the finish of the experiment. The observers could have communicated by pony express without affecting the conclusions. NOT ONLY DID SPECIAL RELATIVITY NOT ELIMINATE THE CLASSICAL AETHER, IT REQUIRES THAT THE CLASSICAL AETHER EXIST!

Chris - 21 Mar 2006 10:48 GMT Facinating. Additionally this velocity transform shown that as the rocket's observed velocity approaches c the true velocity given by the transform approaches infinity.
This makes it appear that all this Einstien stuff is because we use light as our measuring stick by assumption, the special theory of relativity is in fact like perspective and the effect does not really exist.
The mass does not increase during acceleration and there is no twin paradox. You may travel to the stars in a couple of days and come back just as normal for a two day trip.
However the general theory is different and it does appear that near massive objects strange things happen as the space-time matrix contracts as if in a negative hill. When you look at the special theory you get the same effect, the length gradient of the line space v time projects on to space or time by making the path up the slope shorter than the space or the time axis projection and so the diagram cannot be drawn.
I was leucotomised for pointing this out by a criminally insane man calling himself a doctor, his name "Richard" and he lives two streets away. Please Mr psychiatists go away and become a roadsweeper and forget all about your nonsensincal brain theories.

Do Do - 24 Mar 2006 17:08 GMT THE DUAL VELOCITY THEORY OF RELATIVITY (From a book published in 1976)
Vertner Vergon Email: avergon@verizon.net
The special theory of relativity enjoys its unusual status because certain conclusions were made by Einstein that a rational mind has difficulties digesting. There is a saying that many physics theoreticians are correct in their mathematics but err in their interpretations.
The object here is to correct Einstein's misinterpretations and clear up some of the misunderstandings. Rather than analyze the said misinterpretations, we simply present the proper interpretations and let the reader draw his own inferences.
First, we must recognize that what happens to length, mass, energy, momentum and time is simply an observation. These parameters in their own co-ordinate system do not change. There they are known as "proper".
LENGTH
Let us consider length, say the length of a rod. As its co-ordinate system approaches the speed of light, the length of the rod appears to foreshorten. Next we recognize that length and distance are synonymous. We also recognize that velocity is distance/time. Therefore, we are drawn to the conclusion that if the observation of a length contracts, so does the observation of a velocity.
So what we have, then, is the dual situation of proper length and observed length -- and likewise, we have proper velocity and observed velocity, thus, the dual velocity that is the subject of this writing.
We shall refer to the proper velocity as "Newtonian" for that is what it is -- and the observed velocity as "relativistic" because that is what it is.
Next, we note (after proper investigation) that as the velocity of the moving co-ordinate system approaches infinity, the observed relativistic velocity approaches c. The relationship can be written as
V x sqrt(1-v^2/c^2) = v, where V = Newtonian velocity, v = relative velocity, and sqrt(1-v^2/c^2) is the Lorentz transformation -- for which, henceforward, we shall use the letter, R. Thus we have V R = v.
MASS AND MOMENTUM
Amongst other things, this posit clears up the old bugaboo of relativistic mass which was inferred from the expression for relativistic momentum, p: p = mv/R
In this expression, as v goes to c, p goes to infinity. And it was concluded that since v had the limit c, the only way p could go to inifinty was if the mass, m, increased. So Einstein concluded.
But in the light of dual velocities, we see another explanation. Instead of R modifying m, (m/R) it modifies v, (v/R) -- and we see that v/R = V. So it is the Newtonian velocity that goes to infinity.
TIME
We start our examination of the time dilation concept by going to its source -- Einstein's paper, On the Electrodynamics of Moving Bodies. We refer to his gedanken experiment of moving clocks. One of two identical clocks remains at rest while the other moves away and returns. When Einstein perceived the difference of the clock readings in his calculations, he stated the moving clock "was slow by ...". The immediate perception by the public was that he meant if a clock was "slow by" - it had to have run slower. He also said the moving clock was "behind" the inertial clock by ... . These two statements do not mean the same thing. If one clock is running slower, then it is running slower, and that has only one meaning.
On the other hand to say one clock is behind the other is open to alternative explanations, eg, the moving clock could have traveled a shorter world line -- or may have traveled faster than observed. In either case the clock would maintain its normal (proper) rate but for a shorter duration than the inertial clock and thus be behind. At any rate the accepted version is that the clock ran slower and thus was born the concept of time dilation which led to the famous Twin Paradox.
We see here the answer to the problem is that the moving clock traveled faster than observed. The clock in the moving system kept proper time but did so for a shorter duration than experienced by the stationary clock because its velocity (Newtonian) was faster than the observed relative velocity. To conclude that the moving clock kept proper time (which it does) and dilation (slower) time simultaneously is a reductio ad absurdum.
We shall illustrate -- and in doing so, we shall also illustrate the existence of super c velocities. We assume a co-ordinate system that travels at the rate of 1.732 c. By VR = v we see the relative (observed) velocity to be .866c. {R can be obtained from V by sqrt{1/(1+V^2)}.
We set the conditions as follows: The traveling system ,S, will travel a distance of 1.732 light seconds (LS). Since the velocity is 1.732 LS/sec, the clock in the system will record the transit as taking one second. One second up and one second back equals 2 seconds for the round trip. The observation in the inertial system is different. There, the observed velocity (relative) is .866 LS/sec, and the round trip will occupy 4 seconds -- two seconds each way.
However, that is not the way the inertial system actually observes. One has to take into account that in observing a moving co-ordinate system, the time for radiation to transmit the record of it has to be included. So the actual subjective description can be mathematically described as follows:
( where c=1) v_ diverging = v/(1+v), v_converging = v/(1-v). Thus in our illustration the subjective observed velocity in recession is .4641c -- and the transit time is 1.731 LS/.4641c = 3.732 sec.
The subjective observed velocity in approach is 6.4641c -- and the transit time is 1.732 LS/ 6.4641c = .26795 sec.
Adding the recession time to the approach time gives us a 4 second round trip, for the inertial observer whereas it is 2 seconds for the moving observer.
One last consideration. Now that we have established super c velocities, what are the complications?
Let us, as a means of clearer illustration, use the Twins example. We shall call them Astronaut and Astronomer.
We see that to the Astronaut the round trip is two seconds, whereas to the Astronomer it is four seconds. (Let us transpose seconds to years).
What happens when the Astronaut lands and strolls over to stand shoulder to shoulder with the Astronomer? He must necessarily see the same as does the Astronomer. What would that be? And would that violate any laws of physics? He realizes that although only two years have elapsed for him, it has been four years for his brother, the astronomer. To illustrate further, we can imagine a similar situation. We contemplate a galaxy a million light years away. It is agreed that as we observe it, we observe it as it was a million years ago - we are looking into our past.
Should a creature from a planet in that galaxy suddenly appear, we would conclude that he came from over a million years in our past. There is no conflict with known physical laws. The question arises, what about the accepted concept that one can never chase a light beam and catch up to it? *
Consider the following: As one increases their velocity in this pursuit, the beam gradually reduces in frequency - until at the speed of light, there is no frequency at all. Note that the reduction in frequency does not alter the fact of the beam always preceding the observer at c until the frequency reaches zero. That would be c on the relativistic scale and infinitely great on the Newtonian. Thus we conclude it would take an infinitely great Newtonian velocity to catch a photon - which disappears at that velocity because the observer is keeping pace with the EM transmission. ------------------------------------------------
* CHASING A LIGHT BEAM
For an observer to chase a light beam means to chase photons that have recorded his existence and are proceeding in the same direction as he. Since c is a constant, we conclude that the photons will always precede the observer at that speed and he can never overtake them. We therefore conclude that superluminal velocities are impossible. However, we recognize that super c velocities are. We distinguish one from the other. A super c velocity is a Newtonian velocity greater than 3x10^10 cent/sec whereas a superluminal velocity is greater than light - which is potentially infinitely great. -------------------------------------------------- Above, we mentioned time dilation - another misconception by Einstein. He asserted that whether receding or approaching, the moving clock ran slower. The nightly observations of astronomers belies this.
Any known constant frequency is a clock (A certain vibration of the excited cesium atom is the new standard for the second.). Constellations and stars contain excited atoms of known, constant frequency. They are in effect clocks.
We note that, in effect, when these clocks are receding, the observed frequency slows. That means the clock is observed to keep slower time. Conversely, when the clock is approaching, it is observed to run fast. Thus, we are drawn to the conclusion that time dilation as Einstein proposed it is in error for in that concept the clock is running slower.
Not only that but in its own co-ordinate system it would have to keep slower time - and simultaneously keep proper time, as we said before, a reductio ad absurdum.
Another fact that unseats the time dilation concept is that the rate for the two systems are different. The frequency system just described is also known as the Doppler effect. Now "Doppler" is just the name describing the mechanics of it. This does not alter the fact that Doppler rate is observed time rate. I call it "Doppler time". If one examines the figures given in the illustration above, they will discover that the transit times are of the Doppler rate. When used in the Twin Paradox situation, the paradox never appears.
ENERGY
We write generically E = m a d = mv^2 (m = mass, a = acceleration, d = distance) For kinetic energy we write E_k = mv^2/2
This is the Newtonian expression and valid for very low velocities. By considerations not displayed here the factor 1/2 is replaced by 1 /R + R^2
Thus we write the expression for kinetic energy as
mv^2 E_k = --------------- (R + R^2)
It will be found this is exactly equal to Einstein's E_k = (1/R - 1)mc^2 and good for all velocities. We note that the expression for the kinetic energy of radiation is
E_k = h nu = m_photon c^2, which is of the form mc^2. The mass of the photon is derived from Einstein's m = E/c^2. Total energy is E_t = mc^2/R
We also note that in the form, E = mc^2, there is no modifying factor as there is for ponderous bodies. We take this to mean that the Lorentz transformation is not applicable to radiation (except where there is an interaction between radiation and matter in motion).
In the Newtonian case, we also note that the factor ½ is only applicable at very low velocities. In the kinetic energy equation above --- good for all velocities --- we have the factor 1/(R + R^2) replacing ½.
Note that at very low velocities, R is 1 --- and the factor 1/ (R + R^2) becomes ½. As we go up the scale of velocities, this factor goes to infinity as does the velocity.
As stated before every Newtonian velocity has a corresponding relative velocity. It should be noted the parameters of momentum, kinetic energy and transit time found in the Newtonian velocity are associated, unchanged, with the corresponding relative velocity. In short, they do not undergo the Lorentz/Fitzgerald transformation.
It is this phenomenon that accounts for much of the mystique of special relativity --- to wit --- at c velocity the energy and momentum go to infinity, while transit time goes to zero. Recall that the Newtonian velocity corresponding to c is infinitely great - and we would expect the momentum and energy to go to infinity. At infinite velocity, the transit time to anywhere is zero, so the clock in the moving co-ordinate system is assumed to have stopped.
As to length, that does undergo the transformation - which, with respect to inertial time, shows up as a reduced Newtonian velocity which is our relative velocity. (As a seeming contradiction, we note that inertial time times R equals the transit time in the Newtonian velocity, but the fact remains that transit time with the Newtonian velocity is the time attributed to the relativistic velocity.)
