Retro-Causation and The Symmetry of Time

In the macro world the physics of time appears to only move in one direction from the past into the future while in the quantum world according to the Wheeler-Feynman Absorber Theory,  time is symmetric meaning it is also possible that a object in the past could also absorb an electron from the future.

For example, in an experiment called “A Delayed Choice Quantum Eraser (Yoon-Ho Kim, R. Yu, S.P. Kulik and an Y.H Shih, 2000) uses the design of the famous Double Spilt experiment to randomly measure  the wave-particle  phenomenon through the observer effect.

This random observation occurs by creating a set of entangled photons after they have passed either of the double slits. From slit A, one particle is sent to the main detector where it measures the particle-wave phenomenon while the other entangled particle is sent through a random process which either records which slit the particle went through or erases this information. A duplicate process is repeated when a photon passes through slit B.

Remember, the measurement problem occurrs when a detector was put at the double slit location to observe which slit the photon passes through. When this was done the photons act as particles because the detection panel only showed two areas where the photons landed. And when they removed this measurement the photons acts like a wave between the two slits and creates an interference pattern at the detection panel.

The sequence of detection times were controlled by distance. The main photon detector (D0) was the shortest distance, thus all the photons at this location will be detected without any knowledge if the slit information was recorded or not. The second event which is set to a longer distance is generated by a random beam splitter (BSA or BSO) which will ether direct it towards locations (D3 or D4) or (D1 or D2). Each specific path of the photons provide the following information:

1. D1 : No path recorded (erased)
2. D2 : No path recorded (erased)
3. D3 : Path recorded from slit A (BSA)
4. D4 : Path recorded from slit B (BSB)

The experiment concluded that when no path information was recorded an interference (waves) pattern occurred and when the path information was recorded it only showed two areas (particles) where the photons landed at detector D0.

This result was surprising because how can the interference pattern disappear when the photons that followed paths 3 and 4 were measured after the photons have already been detected at D0? One possibility is retro-causation where by the future result affects a past event.

Science has ignored the deeply philosophical questions of the observer effect and has concentrated only on ways to calculate the wave-functions of quantum particles. And even if science acknowledged these retro-causal effects of quantum mechanics it would conjecture that they do not necessary translate into the macro world. However, much of this type of phenomenon has occurred as paranormal effects which are explained as Extra Sensory Perception of human consciousness. Phenomenon such as receiving premonitions and remote viewing could be explained within quantum retro-causal effects. For example premonitions can be seen as a person ability to perceive a future event. While remote viewing is gaining information about unknown targets (person, places or things) regardless of locality or time was first introduced by Russell Targ and Harold Putoff in 1974. Both respected physicist working for the Stanford Research Institute conducted research in this area and developed the protocols and training techniques for Remote Viewing Projects for the CIA, DIA and Army Intelligence in the 1970’s and 1980’s.

In the video below Dr. Garret Moddel, a physicist at the University of Colorado has explored such areas as premonition and psychokinesis discusses a general scientific model of retrocausation.


Precognition has been studied by neurologist and scientist such as Dean Radin who is a senior researcher at the Institute of Noetic Sciences. He developed a experiment where he measured the retinal eye movements of test subjects before and after being exposed to emotional images. The results of this experiments concluded there was significant statistical data supporting that precognitive retinal movement occurred before the emotional images were shown. In the 1980’s there was a meta analysis of this subject done which reviewed over 309 experiments that found precognition did occur but accounted for only a small effect.

If precognitive perceptions are possible due to retro-causation effects, then these abilities of the human brain could account for the survival of the specie by developing this trait. This trait could also be apart of a larger holographic process at the quantum level where data could be shared between species based upon similar genetics increasing its survival rate. This could explain the Hundred Monkey story told by Lawrence Blair’ in his 1975 book, “Rhythms of Visions”. It recounts the research done in Japan during the 1950’s of macaques monkeys on the island of Koshima. In 1952, they observed a group of monkeys washing sweet potatoes before they would eat them, then by 1958 they observed this trait had been adopted among most of the macaques monkeys even those on other islands. Later the skeptics claim to prove the behavior was only adopted among the younger monkeys and the spread to other islands was due to monkeys with this trait swam to those islands. What was important was not how but why this new useful information was shared within a group of genetically related animals. It is obvious that the collection of information is pivotal in the human specie to survive and evolve. Even in the modern age when the internet has taken the place of the Hundred Monkey an informational matrix is slowly becoming a physical reality in the 21st century and a tool which is speeding up our current evolution.
