This is the theory proposed by Atkinson as he menacingly lambasted Einstein's EPR theory (Einstein- Podolsky- Rosen scenario). It is seemingly anti-intuitive that someone could go back and murder their grandfather and therefore return to find themselves non-existent (referred to as the grandfather paradox).
Prof. John Thaler argues that that the Theory of Relativity might permit 'closed timelike curves' that allow time travel, but the famous 'grandfather paradox' proves the whole thing is impossible.
The movie 'The Butterfly Effect' made famous the notion that if you go back to change a past event (backward causation), it causes fractures in the time-space continuum, resulting in new outcomes which are totally unpredictable.
However, backward causation implies a static account of time in the sense that there is no objective becoming, no coming into being such that future events exist on the par with present and past events. It means that the future is real, the future does not merely consist of unrealized possibilities or even nothing at all. Unfortunately, reality is far different and more complex.
Time is nonlinear and non-local.
Everything is in a flux; time, space as
well as energy.
One of the more persistent and logically-cohesive arguments is that there is a physical signal being sent between two photons (the theory of photon entanglement) that are entangled which allows them to operate as they do. What Albert Einstein called 'spooky action at a distance', or 'passion at a distance', involves not going faster than the speed of light but going backwards in time.
It is believed that photon entanglement happens not only in isolated physics experiments in the lab but in every living thing in the universe, including the human brain.
Jack Sarfatti remarks in the Journal of Cosmology that different parts of the brain can locally decode messages from other distant parts without having to wait for classical electrical and chemical signal keys to move slower than light.
This would give the brain a capacity to
hold two types of records; one based on sensual perception and the
other on amnesia (memory).
If there was such a thing, wouldn't we expect physical traces of changes, or memories that conflict with past events, such as was hypothesized by people who remember the 9/11 event.
Some whistleblower testimony exists about purported chrononauts, ones as famous as the current president of the USA:
However, verbal testimony can be disputed, slandered, suppressed or even eliminated.
physical evidence still fails to exist, unless we consider such
anomalous evidence as
20,000 year old screws and
modern watches in
This theory is the background behind
existing quantum key distribution networks (QKD). In other
words, photon entanglement and time travel do not exist, but their
applications in mainstream science are, ironically, commercially
Daryl J. Bem (Cornell University) notes recently that the cause of psychological retrocausation may be due to a phenomenon known as 'psi', which involves unknown processes of information or energy transfer that are currently unexplained in terms of known physical or biological mechanisms.
Bem showed that students were able to guess at future events in a frequency that was well beyond mere chance, in others, it appeared that the future was directly influencing the present. The existence of 'psi' phenomenon is backed by other experiments such as changes in heart-rates in remote viewers during experiments between two isolated patients.
Psi may well underpin transtemporal
phenomenon throughout the universe.
If time travel were possible, one could argue that the past would have been re-written and the Titanic would have been saved from disaster by benevolent chrononauts.
Of course this assumes that the Titanic was an accident rather than a premeditated act of sabotage, and that intention vs. premeditation affects time passage via time portals.
To quote the Buddhists,
Time must be viewed as a polynomial phenomenon, i.e. time has infinite lines of possibility that co-occur at once, in symphony and are changed by personal intent, choice or non-choice.
It is interesting to muse that if the Titanic had been saved from sinking, the passengers would have had an uneventful sail to America, would have disembarked and White Star Lines would have pulled J.P. Morgan (underwriters) with it into insolvency.
No one would have recorded the sinking of the Titanic, and the event would have been wiped from the historical records. We would have no record of the anomaly and therefore it would not have existed.
Thus, on this new timeline, we would be
none the wiser about insurance scams, chrononauts and the whole
mystery of retrocausality.
