The Science of Changing the Past
The Science of Changing the Past
by Cynthia Sue Larson
Some of the world�s top physicists are currently working on experiments, which if successful, will allow us to better understand how we can change the past, and how we are, in fact, already changing the past. The concept of retrocausality first sprang into public view following discoveries in the field of quantum physics back in the 1940s, and has recently experienced a resurgence of popular interest. At a symposium of physicists assembled to discuss retrocausality in 2006, physicist Daniel Sheehan of the University of San Diego commented, "To say that it's impossible for the future to influence the past is to deny half of the predictions of the laws of physics."
Philosophers were among the first to point out that we had fallen into a double standard fallacy of thinking differently about the past and future. In our highly symmetrical and exceptionally elegant natural universe, it seemed odd that events could take place in space in all directions, yet time would only move in one direction. Oxford philosopher Michael Dummett established the logical requirements for the process by which reverse causality could take place, which contemporary philospher Huw Price amended. These requirements simply indicate that: when A causes E, it can be possible to detect whether the event E occurs before the time that event A occurs in such a way that not only is E detectable, but it's detectable without disturbing the circumstances under which A causes E.This roughly translates to, You can change the past as long as you're stealthy enough to observe the way things used to be, and make a change without being caught.
With such simple logical requirements for retrocausality, we can expect to be able to look for and find evidence of retrocausality all around us. It might appear in the form of otherwise inexplicable events such as spontaneous remissions of inoperable tumors, as people notice cancer vanishing without standard medical treatment. We can expect to see things like parking spaces being just where we need them, when we need them... because we have already asked for a space to be cleared in advance of our arrival. We can ask for mistakes we've made to be fixed in the past, so we need not cry over spilled milk when were open to experiencing a situation in which the milk was spilled... but now its not.
A brand new retrocausality experiment is just beginning at the University of Washington, where physicist John Cramer is working with colleagues to show how light might appear before it is transmitted. Cramer's experiment is particularly noteworthy, since he is known as the originator of one of the most interesting interpretations of quantum mechanics, the transactional interpretation. The transactional interpretation proposes that events take place on the quantum level when they are established as a kind of standing wave which forms when there is a kind of handshake between retarded (forward in time) waves and advanced (backward in time) waves. While we normally observe retarded waves that move outward away from emitters in a past-to-future causality direction in much the same way as ripples move away from a pebble tossed into a pond, Cramer described that there also exist advanced waves which transfer energy, momentum and other information from the future to the past.�
Another exciting experiment in retrocausality is underway as Physicists Stephen Hawking and Thomas Hertog's conceptualize a 'top down cosmology' view of the universe having begun in every possible way, with the most probable pasts being determined now. This experiment will monitor background radiation from the Big Bang, noting how many Big Bangs may be observed. In contrast with the assumption that time must always flow in one direction from past to future, this new cosmological model depends on the retrocausality idea that effects can precede causes on all levels of reality, not just in the quantum realm. The theory of "top down cosmology" presented by physicists Stephen Hawking and Thomas Hertog describes how the universe can be viewed as having had no single unique beginning, but that it actually began in every possible way. Hawking and Hertog suggest that countless alternative worlds existed at the time of the creation of the universe, meaning that we can now picture the universe in its first moments as a superposition of all possibilities, something like watching an infinite number of movies playing simultaneously. Referring to quantum experiments that have consistently shown how quantum particles exist in both wave and particle form, essentially covering all possible paths, Hertog clarifies: "Quantum mechanics forbids a single history"
The potential for paradigm upheaval with the advent of retrocausality is perhaps the biggest shift in scientific thinking to come along since the Copernican Revolution. A world view in which we can influence the past can encourage people to start holding hope for not just a better tomorrow, but also for a better yesterday, without nearly so much angst and stress... since being able to change both the past and the future puts an entirely new light on conscious creation. People who've made mistakes can seek ways to undo them, and entire communities can join together to reduce global problems like pollution, crime, over-population and global warming.�
