In this paper the results of four different experiments on heart rate pre- stimuli reactions are presented. Results show that even though subjects guess randomly, a strong pre-stimuli difference in the heart rate is observed during the presentation of the color stimuli, later selected and shown by the computer. All four experiments have confirmed pre-stimuli reaction of heart rate, and have shown new characteristics of the effect. The first experiment shows strong differences in HR measured in phase 1 for the blue and the green colors when selected by the computer in phase 3. The second experiment shows strong differences for all the colors and also when numbers are used. The third experiment shows the absence of the effect when the feedback, the selection operated by the computer, is not shown. The fourth experiment shows the retrocausal effect on all colors, the learning effect described by Damasio and an interaction between these two effects. Introduction The solutions of Klein-Gorodon’s equation (quantum mechanics relativistic wave equation), which can be considered the fundamental equation of the universe, depends on a square root: ܧ ൌ ඥ݌ ଶ ൅  ଶ  Klein-Gordon’s equation relates energy (E), momentum (p), m (mass) and Schrödinger’s wave equation (ψ) Square roots always yields two solutions, one positive and one negative: 1. the positive solution describes waves and causes which propagate from the past to the future; 2. the negative solution describes waves and causes which propagate backwards from the future to the past. In the 1930s the negative solution was rejected as it was considered incompatible with our experience of time which moves from the past to the future. However, as the mathematician Roger Penrose points out in his book “The Road to Reality” (Penrose, 2005) “Usually physicists tend to reject as unphysical 1 antonella.vannini@syntropy.org 2 ulisse.dicorpo@syntropy.org
