I don’t generally delve into the subject of time travel because it’s kind of hard for my poor mammal brain to comprehend.
Well, I kind of understand Einstein’s Theory of Special Relativity (or is it Special Theory of Relativity?) because I’ve read science-fiction for 45 years and have actually taken physics courses in high school and college. I get (not grok) that as an object approaches light speed it increases in mass and if an observer was on the object, time would go slower for them than the outside Universe, in essence transporting the observer into the Future.
I get that.
What I don’t get is quantum theories that speculate time travel to the past and this tanj-blasted Grandfather Paradox.
Yeah, that one. The one where the perpetrator manages to travel to the past and kills an ancestor, either purposely or accidently, resulting in the conundrum of if his ancestor dies, how does this person come to the past in the first place?
And he gives an explanation why it isn’t possible to begin with.
Just two days ago here at Barf Stew – I blasted the idea of Time Travelers –http://barfstew.blogspot.com/2010/07/time-travel-is-impossible.html presenting many reasons why it was impossible. Not only that I didn’t even use the ONE REASON the simple thinkers always trot out – the one that says – IF you could go back in time you could end up killing off your ancestry (ie:killing your father, or grandfather – why is it never your mother?) and therefore making one’s own existence impossible to occur.
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.

Hmm…one can not return to ‘the real?’
But isn’t ‘real’ a property of ‘perception?’
That’s the trouble with this stuff, nobody really truly knows anything!
But as the wise man once said, “It’s not the destination, it’s the journey!”
