In the 1945 paper by Wheeler and Feynman, Interaction with the Absorber as the Mechanism of Radiation (Rev. Mod. Phys. 17, 157 - 181 (1945) for the first time aspects of charged accelerated particle and its EM waves of a retarded type (propagating forward in time) and advanced (propagating backwards in time) type were studied.
Both waves are acceptable solutions to the classical Maxwell equations and there is nothing the relativistic Quantum Mechanics interpretations that forbids waves propagating backwards in time.
Recently a paper in the cognitive psychology field has been published on the subject of retrocausality (ref. 1), which is term a psychologist would use to define possibility of "advanced wave flowing backwards in time" concept in physics.
The normal theory of causality in the mind-world interaction makes use of forward flowing causality where one event precedes another, in the experiments quoted in the paper however, this causality is inefficient to explain results of the experiment. The result points to innate and strange ability of the mind to interact with the world where the concept of forward flow of time is challenged!
Quote from the paper:
Retrocausality in REG (Random Event Generator) experiments. In 1979 the PEAR (Princeton Engineering Anomalies Research) laboratory was established under the direction of Robert Jahn, Dean of the University’s School of Engineering and Applied Sciences.
The purpose of this laboratory was to replicate and study the results obtained by a student which showed anomalous mind/machine interactions when using REG systems.
PEAR and a consortium of other universities have replicated these results. The anomalous mind/machine interaction which is observed is very simple: REG systems produce ultra-precise gaussian distributions, but when a subject tries to distort these distributions only by the expression of his intentionality, statistically significant deviations are observed.
Even more fascinating is the fact that those distributions which have been produced before the subjects’ expression of intentionality show an amplified effect.
The statistical significance of these “retrocausal” amplifications is p<0,000000001 (Jahn, 2005).
