Wow! Questions questions questions! Ok, let's see. I'll give you some quick answers here in order.
1. Mylo - no. Our Timeline's are broadly similar, but not identicle. (and we call them 'Worldlines'). I don't know what you were told in the realm of this Titor mythology, but my Time Displacement Unit doesn't automatically confirm the displacement differential between worldlines unless specifically analysed to do so. As I said, I am not an engineer, but was told there would like me a .4 or .5 variance, or 'percent' if that's an easier term. For instance, a .1 variance would indicate a Worldline that is very similar to the one you're leaving; as to be almost identical. So .5 is pretty much broadly similar, with some significant events differing around the globe. To be clear - yes, we had a WW1 and WW2, and the allies won, the Nazi's (Axis powers) lost, just like here.
However, the last few years of this Worldline do differ from mine somewhat. For instance, right now your Russia is still a Republic. On my Worldline, in 2008, Russia declared a state of high alert, Vladimir Vladimirovich Putin assumed a new term as President but quickly formed a coalition with Communist Party of the Russian Federation and Russia was effectively a communist state again from 2009 onwards.
2. Paula - the toughest thing, it seems to be, for people to believe that someone who has travelled from another Worldline is indeed who they say they are, is the lack of proof. People want pictures of future dome cities (we don't have those!), or a video of a time machine zapping into existence from thin air. These things are all technically possible, but can you imagine, right now, what it would do to your world should you suddenly have 100%, unequivocal proof that, for want of a better term let's call them "Time Travellers", were visiting your world? The knowledge that people from 20+ years from now are zipping in and out? First, it would change the way you think about yourselves, as the reality of Time Travel did for my society. It would raise questions of religion, science, personal freedom. Not to mention the fact that, by 2037, this era is considered one riddled by corrupt governments, run by Freddy politicians, who rarely had the best interests of the majority at heart.
I think we both know that if I was to come to you with pure, hard evidence of my technology and what it could be used for, not only would my assignment be put in jeopardy, but my very freedom as well. I'd give it an hour or two before MI5 or some other branch of British Intelligence was kicking down my door. The truth is - anyone who is truly in my position would of course want to keep you guessing. I'm sorry, but no genuine time traveller is going to be stupid enough to unleash unarguable proof of his ability to traverse worldlines, until he was literally moments from escaping your Worldline forever.
3. Yes Titorite, I have heard of Rife frequency generators. I'm surprised you would bring such an unsupported technology up. I'll happily confirm for you - no. In 2037, we do not use Rife machines to treat cancer or any other ailment. Those generators produce low energy waves and I can tell you, trying to blast diseased cells with electromagnetic frequencies does nothing for the treatment of disease. However, I can tell you that by 2032, we had virtually perfected medical Nonotechnology for a wide range of treatments and that it is nanotechnology which is going to make the most significant impact on both the medical field and the human lifespan in the future. Also, no. I have not been asked to retrieve anything from this timeline other than pictures, video footage, and to scribe my own personal observations and reports on events and current world affairs.
Please understand - I'm not comparing myself to this John Titor character, because IF he was real, he clearly worked differently. The entire reason I was sent here, was specifically because this Worldline differs in area's from my own. In my field, we consider it not as helpful to study Worldlines almost identicle to our own. We know what happened there and how it turned out! My work is the study of 'alternate history', if you will. How events in our past night have turned out differently, and what the governments and oeople of your world here and now are doing differently to what we did, and how that is changing the course of events for you, as opposed to my own history.
4. Finally, PaulaJedi, I don't subscribe to the multi-Worldline theory theoretically, our science has proven it to be true! Universal wavefunction is a scientific reality in 2037, and has been in fact accepted since 2033. For every quantum event, another universe branches off. Everything that can happen, does happen, in an alternate quantum reality. Of course, entering the past would itself be a quantum event causing branching, but we now know that when someone engages in temporal displacement, the timeline or Worldline accessed by the time traveller is simply another timeline of many.
This is why we still have strict protocols regarding our interactions with other worldlines. Nothing I do here can affect the future of the Worldline I came from in any way, but it could still affect yours. It's a moral and ethical concern really. Just because we are safe in the knowledge that our travelling back cannot screw up our own futures, it doesn't give us a right to screw up yours.
Phew! Did I go a bit long there?
