Actual Changes to the Past

Actual changes to the past is a far more difficult concept to wrap ones head around than is the idea that alternate pasts already exist and only some of us have a recollection of them. Both concepts require an agent of causation which today is not widely accepted by the scientific community nor the totality of people who assert they are the beneficiaries of selective knowledge.

For some people the explanation for differing memories is that they themselves appeared in this reality from a different timeline. While this is a lofty and romantic notion, precisely how many ME examples did it take to bring them to that conclusion? Is it a preponderance of examples that helped form their conclusion or is it a feeling that it must be so? A lot of people assert they remember the ME namesake, Nelson Mandela dying in prison in the 1980s but when pressed for any details such as the date, they are absent an answer.

The opposite condition is also an explanation. In that variation, in is not the observer who made the transitions between realities but the events themselves. To those observers the alternate events and conditions are only represented in their memories but not in any remaining physical artifacts.

This brings us to the variation where a single coherent past is actually modified by some (as yet) unspecified agent of causation. The LHC at CERN is one alleged cause. A superior alien civilization is another. Our future selves as time travelers are also suspect. Even ancient earthly civilizations residing inside a hollow earth are hypothesized as the instigators. Lastly, mere quantum perturbation might result in a spontaneous modification of what was originally manifest and some people escaped knowing about the change.

"My biggest smack in the side of the head was digging out my old copy of Springsteen's Born in the USA to see that it indeed is now a red visor cap in his pocket not his signature red bandanna."

Realizing that all matter is really energy waves until an observer observes them makes the next explanation plausible. Every two (or more) waves which interact with each other encode their own natures in each other. Waves move in the three ordinal directions (x,y,z) and one of time (present into the future). Waves also move in the negative ordinal directions. There is nothing to stop them from moving in a negative time direction also.

How far back they have an impact has never been fully explored, although physicists know waves do this. They also know future events help determine the causative events which made the future what it is (will be.)  ME experiences may be a manifestation of backward traveling Event Waves which mix with the "immutable past" and alter it in small, medium and large ways. We only see the changes to things which we have recent memories of with to compare. for example we can discuss the apparent changes of a word in the Bible because we have a Bible to go look it up in. But in a Retroactive Event Modification wave removed an entire chapter from the bible, we could only speculate on its name and what it said. We might go looking at the list of "Lost Books" of the Bible that were proposed but never approved as possible candidates.

So now at this point in time each person must choose his/her own explanation for what they believe.
