And that way, hilarity must ensue... I also believe I may have mentioned something about Time Travel being simply murder on the tenses. One never knows where one is with the silly business. You are, however, perfectly correct. And in no way shape or form, in anything I may have describes do I suggest anything any different. Please Register or Log in to view the hidden image! Quite the contrary. Travelling backwards through Time doesn't place anyone in "The Past" - merely just a point in Time & Space which, chronologically speaking, proceeds that one, originally, the Time Traveller leaves and thinks of as being "The Present." This is one of the reasons notions concerning Time Travel rapidly become such a pigs ear - one never knows where one actually is. Certainly, if a Time Traveller begins their journey at 12:10 am on August 29th 2006 and arrives ten minutes earlier (as in the diagram above) his pocket-watch (an essential piece of kit for any gentleman Time Traveller of distinction) is ten minutes ahead of everyone else's, his experience tells him that if the purpose of making this journey is to win a wager concerning a coin, the outcome he believes he has already witnessed and knows to be Tails (sorry about the devaluing of currency here by the way, I literally don't appear to have anything on me at the moment with a monetary value exceeding exactly one penny) - Everything as far as the Time traveller is concerned informs him that where he is is ten minutes ago in "The Past." The problem is he isn't. Physically speaking, when one Time Travels, one leaves the present and arrives in the present - when and where in Time & Space doesn't matter a damn. Your arrival point, it doesn't matter what it says on either clock or calender, is always the present moment as far as where you arrive is concerned. Consequently, events may unfurl exactly parallel to how a Time Travellers knowledge of "History" is concerned - or they may unfold differently. The exact outcome of the wager is absolutely no more certain than it was the first time around, it is only the Time Travellers own perspective of things which makes either him or her believe otherwise. Reality both can and may beg to differ. To travel through Time is only to travel from one given point in the fabric of Time & Space to arrive at another - chronologically this arrival point may proceed the point in Time & Space one may originally have started out from but all one is ever doing is moving between two separate points in Time & Space. One never arrives in "The Past" - what happened is indeed fixed, immutable, unchanging and unchangeable. Nevertheless Time Travel has physically placed the Time Traveller at a point in Time & Space that chronologically conforms exactly to his or her understanding of that point in time they, as a Time Traveller, can only regard as being "The Past". To travel forward, either with the flow of or through Time to the point in Time & Space which, chronologically speaking, conforms to the point they originally left - events as they actually transpire as far as reality is concerned are simply what happened. A Time Traveller may view the outcome as being somehow either "wrong" or else "different" - of course in practice this is simply not at all the case, but the Time Traveller, with their unique point of reference as such an individual, will suffer the consequences of such "change" uniquely compared to everyone else. The world and reality around them, whatever happens, will carry on just fine - but the Time Traveller, from the moment they first travelled back through Time, remains out of place. Literally, because they are exactly so. For a Time Traveller, travelling purely for the sale of travelling back through Time, there is no going back to where they originally started. It's a one way ticket. The very best one could ever hope for, in returning to what corresponds to being the point in Time & Space they originally left, is finding a reality with a history of chronological events so exactly parallelling that which their own particular experience of "History" dictates should be there as to make negligible difference. This, once again, is getting to the nub of why Time travel for the sake of travelling back through Time is so supremely and utterly useless. If y'can't use it to correctly anticipate the outcome of the simple flip of a coin - what can you actually use it for? When viewed and applied in the context of facilitating interstellar travel on a viable basis, Time Travel is the side effect that makes that notion a viable undertaking to strive for in the first place. But Time Travel just for the sake of travelling back through Time...? Y'can't even use it to win the Lottery. Being randomly generated a quick jaunt into the future may reveal indeed exactly what each winning number is going to be - but travel back to apply that knowledge and, just as in trying to apply ones knowledge of the future to win a single coin, the actual odds of the numbers Time Travel has revealed to you being the exact same ones that come up when you endeavour to apply the knowledge remain exactly no different than had you never gone to the bother. 1/14,000 against. The odds of a coin coming up one side over the other - 50/50. Go to Las Vegas all you want, as a Time Traveller one is no more likely to win than any of the other punters there. It never matters quite exactly what ones knowledge of "History" informs them. Nothing I've stated in any of these posts either constitutes or is proffered as providing any form of physical prohibitation to the idea of Time Travel whatsoever - quite the contrary. Fix yourself up something that can get you from one star system to the next and back again and still find someone alive enough to give a rip you actually sent out there in the first place and that is essentially everything anyone will ever need to facilitate Time Travel in that specific sense of setting out to displace chronological Time. If using worm-holes are your particular bag, it's as good a way as any. The point is, affecting Time Travel in this specific "travel back in Time" sense is useless, utterly, and pointless beyond reproach to undertake. Only an idiot, providing they had the means, would actually do it and consider the venture even remotely sane... But then again, last time I checked. The world apparently remains full of idiots and we remain the exact sorts to look back at our predecessors and consider ourselves actually smart simply because we can work the appropriate buttons on a computer. Quite why that should remain likely to change particularly in any given future I have not the slightest wit to discern. Time has always been more than merely replete with more than its fair share of idiots. Who knows, perhaps some of them are actually from it... A Please Register or Log in to view the hidden image! An eminently appealing notion, and I have the crowfeet around my eyes just to prove it. But nevertheless, factually inaccurate. Time is what happens.
