Well, it seems the mathematicians have finally, possibly, figured out a way for their `time equations' to filter actions like that out of the equations. Time travel theory avoids grandfather paradox - http://www.physorg.com/news198948917.html (my thanks to Bruce Duensing for sending me this link yesterday). And, if you go to the link - you can see the equations and hear the convoluted logic employed to justify the mathematical possibility.
But, I am here to say this - IT DOESN'T MATTER - that math provides such a scenario. And, the reason is tangled up in two of the reasons I presented two days ago: 1) we live on a planet 2) actualization provides realness as Phenomenology overrides `math potentials'. ---------- Let me explain the best I can.
First, let me say that IF we didn't live ON a planet - that I'd probably be willing to accept `math answers' to the time-traveler saga - but we do live on a planet. OUR space (body) is directly tied to this other object - our planet. But, if it didn't - if somehow we were a `freely occurring space' (maybe like we will be AFTER we are DEAD) - with NO TIES to outside phenomena (the entire motion of our galaxy in our particular location) - then, and only then, perhaps `time' wouldn't matter.
But, Phenomenology provides a basis for actualization of space - a determinism to spaces - turning our local reality for a singular observer (like a human) into a `not-able-to-not-be' AS the moment of NOW. Indeed, EVERY actualized space-moment is `not-able-to-not-be'. And that `not-able-to-not-be' is what `provides realness' to our experience; and to even the `sperm' of our grandfathers.
We simply - CAN'T GO BACK - to realness. Realness IS ONLY an attribute of the NOW; of the `not-able-to-not-be' for the observer-experiencer. The not-able-to-not-be's of the past EXISTED but DO NOT EXIST (to return to). `Closed time-like curves' - do not reverse the Earth's motion in some sort of `running the film backwards'. Earth's motion is in a `frame of reference' to `other spaces' and ONLY has NOW as it's attribute.
The `Earth', and placement of that Earth to our grandfather, is not only NOT HERE - it is NOT NOW. That here and that now - RAN OFF the structure of phenomenology as it provided `realness' to existence. And, the fact that mathematicians can use equations to show that the past has/had areas that prohibit CHANGING THE REAL is hardly surprising to a Phenomenologist as myself - as the actualized, determined, past WAS the real.
So, I will end today's post the same way I ended the post two days ago - It is good that the past can't be changed - because - IF it could - it wouldn't have been real. And, since REAL is only an attribute of NOW - the fact that mathematicians have solved the Grandfather Paradox - Doesn't Matter.
