There is no evidence for advanced waves because almost no effort has been invested to detect advanced waves. From one rare attempt; Schmidt (1980) A search for advanced fields in electromagnetic radiation: 2.8 THE NECESSITY OF A DELIBERATE SEARCH One may ask whether advanced effects, if they do exist, would have already been observed, in the course of human experience. The presence of local absorber, whose response would cancel advanced effects, is rarely avoided inadvertently. In earth-based radio or light communications the line connecting transmitter and receiver, when extended in both directions, almost always intersects absorber. Even if this were not the case there are two reasons why advanced effects might not be seen without a deliberate search " First, the advanced signal arrives in such close time proximity to the retarded signal as to require a deliberate effort to distinguish the two. Second, the intensity of the advanced signal, as a fraction of the retarded, is given by the fractional absence of ultimate absorption. So, in the case of p a r t i a l absorption, any advanced signal would appear attenuated and might require deliberate signal processing techniques (integration) to detect. Finally, one must never forget the power with which paradigms direct the work of scientists (Kuhn, 1970). Anomalies encountered in work peripheral to an experiment tend to be discounted unless they interfere with the goal of the experiment. All of these considerations argue for a deliberate search for advanced effects. Unfortunately, in his attempt to detect advanced waves Schmidt did not take into account the influence of the receiving antenna (a half-wave dipole) on the cancellation of advanced waves from the transmitting antenna (for that exact direction of radiation, as I pointed out in the paper I provided in my first post and in the reference 14, which is the reproduction of the Schmidt experiment in 2017 in the modified configuration, in which the influence of the receiving antenna was taken into account, as well as the influence of water vapor in the troposphere and absorption of interstellar hydrogen, which Schmidt also did not take into account). -- You received this message because you are subscribed to the Google Groups "Everything List" group.
