Analysis of the Electric and Magnetic fields generated by a moving dipole source shows that contrary to expectations, the speed of the fields are dependant on the velocity of the source in the nearfield and only become independent in the farfield. I addition, the results show that the fields propagate faster than the speed of light in the nearfield and reduce to the speed of light as they propagate into the farfield of the source. Because these effects conflict with the assumptions on which Einstein's theory of special relativity theory is based, relativity theory is reanalyzed. The analysis shows that the relativistic gamma factor is dependent on whether the analysis is performed using nearfield or farfield propagating EM fields. In the nearfield, gamma is approximately one indicating that the coordinate transforms are Galilean in the nearfield. In the farfield the gamma factor reduces to the standard known relativistic formula indicating that they are approximately valid in the farfield. Because time dilation and space contraction depend on whether near-field or far-field propagating fields are used in their analysis, it is proposed that Einstein relativistic effects are an illusion created by the propagating EM fields used in their measurement. Instead space and time are proposed to not be flexible as indicated by Galilean relativity. A paper arguing this proposal is available for download at: http://folk.ntnu.no/williaw/walker.pdf William D. Walker William there have been suggestions that the recently confirmed negative refractive index materials also imply superluminal propagation for near field light waves. Supportive of this idea, but not proving it, is that in one experiment the light cone from negative refractive index materials at radio wavelengths has been found to move backward. It is well known that a superluminal signal will appear to move backward when observations are made of it with c light signals. It seems to me that FTL transmission of near field waves should be easy to test for long wavelength radio waves. Say if you created radio waves hundreds of meters long then the near field also extends to a distance of hundreds of meters. Your papers tested phase differences as an indication of superluminality, but a true test would really test the time of transmission. The speed c is 300,000,000 m/s. This amounts to 3.3 nanoseconds to traverse 1 meter. Then a few hundred meters distance would take in the range of a microsecond to traverse for a standard light signal. This is well within the timing capabilities of equipment available at most universities to determine if the transmission is indeed occurring faster than c. The distance of a few hundred meters is also easy to arrange for the distance between transmitter and receiver. The antennas also would have to be a quarter to a half the wavelength but could be made vertical: Very low frequency. http://en.wikipedia.org/wiki/Very_low_frequency Low frequency. http://en.wikipedia.org/wiki/Low_frequency#Antennas Note that for a convincing test you would need to prove the round trip time is less than that for c. This is because other prior experimental indications of superluminal tranmission, which resulted in for example a light pulse appearing to exit the test equipment on one end before it had entered the front end, were interpreted as only being due to early precursors of the entering pulse creating the full pulse at the exit. See for example the explanations of these prior experiments he Light pulses flout sacrosanct speed limit Peter Weiss Science News Online Week of June 10, 2000; Vol. 157, No. 24 , p. 375 http://www.sciencenews.org/articles/20000610/fob7.asp Light Exceeds Its Own Speed Limit, or Does It? By JAMES GLANZ New York Times, May 30, 2000 http://partners.nytimes.com/library/...ics-light.html It might be sufficient to simply have the signals be bounced back to the origin point for a convincing test. But better would be to have a separate receiver generate and transmit back a separate near field signal on reception of the first signal of a quite different character, wavelength, polarization, etc., to ensure there really was signaling being transmitted from one place to another. The negative refractive index materials are complicated to make at visible wavelengths because the materials have to be constructed at the nanoscale, smaller than the wavelength. But they are easy to construct for radio wavelengths, which is why they were first confirmed for microwaves. They should be even easier to make for wavelengths of hundred meter lengths. And if your suggestions are correct we wouldn't even need these special materials since you say near field waves routinely travel faster than c. I noted that in your papers as well as in discussion of those previous indications of apparent FTL transmission there was much discussion of the "conflict" with causality. It is important to realize that even true superluminal transmission of signals does not have to imply signaling back in time. This is because the experimental results supporting relativity can be fully explained as light traveling faster than c in one direction and slower than c on the reverse direction, so that the average speed is c. There has been no experimental confirmation of the one-way speed of light. All experimental methods to determine the speed of light actually have been round trip observations. This fact has been well known to researchers in the foundations of relativity but apparently has not filtered down to the general physics community. See the discussion of this topic he Conventionality of Simultaneity. http://plato.stanford.edu/entries/sp...e-convensimul/ Bob Clark |

In the nearfield the fields propagate with infinite speed and in the farfield they propagate at speed c. Do atoms emit photons with infinite speed? Please explain to me how this violates relativity theory. The analysis I have present in my paper: http://xxx.lanl.gov/pdf/physics/0603240 discusses the propagation of the EM fields created by a oscillating charge. At distances much less than one wavelength the fields propagate with infinite speed and as they propagate away from the source they reduce to the speed c. Photons come from a quantum mechanical description of EM fields. Although photons are known to propagate at the speed c in the farfield, their propagation behavior in the nearfield is poorly understood. In the derivation of Einstein relativity theory, propagating EM fields are used to measure the location of points from a stationary frame to a moving frame. This is done by measuring the time delay of a propagating EM field from one frame to the other. Since the time delays very near the source are instantaneous then it can be shown that the Lorentz transforms reduce to the Galilean transforms there. This can be seen by substituting infinity for c in the Lorentz transforms. In the farfield the time delays of the fields increase to light-speed time delays and the Lorentz transform applies there. A more detailed analysis is presented in my latest paper: http://xxx.lanl.gov/pdf/physics/0702166 The dilemma is that the space-time transformations should be independent on whether near-field or far-field EM fields are used in the analysis. My proposal is that Einstein relativity theory is a illusion caused by the EM fields used to measure the space time effects in moving reference systems. Space and time are actually inflexible as stated in Galelian relativity and only appear flexible when far-field EM fields are used to measure the space-time effects in moving reference frames. When near-field EM fields are used, time dilation and space contraction effects will disappear. |

You may be right that a modification of relativity will be required that allows superluminal speeds (as I argued this will not require causality violations) but time dilation effects have been confirmed for round trip measurements, which do not have the shortcoming of needing light speed c time synchronization. So time dilation will still be required. Bob Clark |

Bob My proposal is that The Galelian transformations are what are real and that the Einstein relativity transformations are useful in only calculating the illusion of time dilation and space contraction. Space and time are actually inflexible and only appear inflexible when propagating EM fields are used to measure their effects. If you use near-field EM fields to measure the space-time effects on a moving frame then no time dilation and space contraction effects will be observed. But if far-field EM fields are used to measure the space-time effects on a moving frame, then time dilation and space contraction effects will be measured, but the effects are not real. Time and space are not really changing, they only appear to change because of how we make our measurements. In between the nearfield and farfield gamma will change in a continuous way enabling the *apparent* time dilation and space contractions to be calculated. Refer to my lasted paper for a qualitative look at how the relativistic gamma changes continuously from nearfield to farfield: http://xxx.lanl.gov/pdf/physics/0702166 William D. Walker |

Bob Clark Bill, perhaps you can answer this question for me. More convincing tests would result from longer distances between transmitter and receiver, perhaps longer than millisecond travel times for normal c light signals, where the near field light waves beat these travel times. For this you would need wavelengths at hundreds to thousands of kilometers to detect the near field effects, with the c light signal travel times at milliseconds or longer. I'm still talking in regards to something that could be easily accomplished by university physics departments or amateur radio HAMS. My question is could you make the transmitter size be much smaller than the size of the wavelength? Perhaps for example by using widely separated elements that are each small in comparison to the wavelength? This page which discusses PC based reception of very low frequency waves suggests the receiving antenna can be much smaller than the wavelength: Very low frequency. "PC-based VLF reception PC based VLF reception is a simple method whereby anyone can pick up VLF signals using the advantages of modern computer technology. An aerial in the form of a coil of insulated wire is connected to the input of the soundcard of the PC (via a jack plug) and placed a few metres away from it. With Fast Fourier transform (FFT) software . in combination with a sound card allows reception of all frequencies below 24 kilohertz simultaneously in the form of spectrogrammes. Because PC monitors are strong sources of noise in the VLF range, it is recommended to record the spectrograms on hard disk with the PC monitor turned off. These spectrograms show many interesting signals, which may include VLF transmitters, the horizontal electron beam deflection of TV sets and sometimes superpulses and twenty second pulses." http://en.wikipedia.org/wiki/Very_low_frequency This page also suggests the receivers for extremely low frequency and very low frequency waves could be quite small: Ultra Low Power ELF/VLF Receiver Project. http://www-star.stanford.edu/~vlf/ulp_reciv/ulp.htm The question is how small could you make the tranmitting antenna for wavelengths hundreds to thousands of kilometers long? You would also have to put the transmitter at a high height for a straight-line transmission because of the curve of the Earth. In this case you wouldn't want to repeatedly bounce off the ionosphere because that would detract from the speed of the transmitted signal. If the transmitting antenna could be made small you could perhaps use high altitude balloons, something many universities have done experiments with. Or perhaps you could put the transmitter at the top of a mountain or high plateau. If the method of widely separated elements for the tranmitter would work then we can imagine more advanced tests at wavelengths of hundreds of thousands of kilometers long carried out by spacecraft where the transmission time for c light signals would be seconds and longer and see if the near field light waves can better these transmission times.
