Experiment Shows, that Group Velocities for Ultra Low Frequency Voltage Signals in Short Coaxial Cables Can be Significantly Faster Than Light

Authors: Steffen Kühn

Recently, during the experimental testing of some basic assumptions in physics, it became apparent that ULF voltage signals in coaxial cables with a length of only a few hundred meters exhibit very anomalous behavior. In particular, they seem to propagate significantly faster than light. The basic idea of the experiment described in this article was to determine with a dual-channel oscilloscope the delay that occurs when the first input is connected to a signal source via a short coaxial cable and the second input to the same signal source via a long coaxial cable. It was observed that the delay between the two channels does not only decrease as expected with decreasing cable length, but that when falling below a certain frequency the delay becomes so small that the associated phase velocity exceeds the speed of light. It is also remarkable that even band-limited signals such as music tracks or speech can be transmitted several times faster as with the speed of light without noticeable loss of quality. Should the observations described here be confirmed, this would be proof that information can be transmitted faster than light.
