Technically, since he says that he was born in 1998, wouldn't that mean that he is alive and living somewhere in... Florida... right about now? Now, if he did give us his real name, which I doubt is true, would he be traceable?


Just some random thoughts from the peanut gallery.

Actually that "therapist" was me. I was just trying to lure him out into talking so I could verbally corner him, but he wasn't biting. I'd love to have a crack at debunking him, but alas, the chance is gone *shrug*

I just thought if you were really interested in talking to him you could use 'PM'. I knew it was you though because I read your name off pretty well.

Hmm, you're really vicious with the debunking aren't you? Heh, I wouldn't treat it that seriously!

Actually though appearances may decieve, I'm an avid supporter of "valid" alternative theories. It's people such John Titor with too much time on their hands who detract from the valid claims, in much the same way fanatical abortion clinic bombers detract from the pro-life cause. With people like him around, it's no wonder the scientific community won't even contemplate subjects like UFO's due to it's attraction of fanatics.

90 percent of what's out there is bunk. It's the other 10 percent I'm interested in. There's always a little "science" in science fiction.

"when all possibilites have been eliminated, whatever remains, however unlikely, must be the truth.

Oh and I did contact Pamela, and invited her here to discuss JT, but she never responded. Perhaps because I wasn't a "believer"...

I have the ability to travel through time, The possibilities are completely endless... first thing on my to do list.. go to an internet forum and post to people about the ability of time travel without giving them any actual shred of proof, or describe factual events in detail...

come on guys... i mean if you could time travel... is that how you would spend your time in the past??
 
  • #58
I know, he never explained why he came onto the forums very well. I'm a skeptic but a entertaining story he paints. I hope he isn't some psychotic delusional but just some normal headed prankster. That would be funny then. Hopefully one day he comes out and admits it. Of course if I'm wrong, it would suck a lot because I'm happy being a fat lazy slob in a rich capitalist country. Except, I'm not fat.

PS Zantra where did you go? And who is this pamela character?

Original Titor Files

Hi All,

I am one of the original people involved with John Titor when he began posting on the Art Bell site.

Someone contacted me and told me that folks here doubted that the files we have were "original" or posted "way back when".

As the Chief Admin for the Anomalies Network (retired) I can assure you that the files we posted were originally from the Art Bell site and our own files are at least 3 years old.

Thus, rest at ease about the posts being "faked". They were not.

Our time travel section is the original section as it started several years back.

Thanks.

Hi Rick,
First, thanks for posting. Have there been any serious efforts to debunk this guy? For example, I suspect that his time machine GE/C204 is a mobile receiver unit used by the military.
 
  • #61
yes. on anomalies.net, what appears to be a serious physicist picked apart john's claims and concluded that the claims are not sufficiently grounded in currently understood physics. i suppose the ultimate conclusion is that john is a faker. i believe links to this counterargument have been posted by zantra earlier in this thread on PF.

i know this is illogical of me, but i reserve the right to doubt logical arguments no matter how impeccable the logic is. what would really prove it to me to be negative would be if john came to me (or i to him) with his supposed machine and it didn't work.

to give an analogy, suppose a time traveler went back to 1935 with an F-16. he writes letters to aero people saying that he is a time traveler with a machine capable of supersonic flight. they would come up with convincing arguments to prove that is impossible; the lay person would accept their impeccable logic which says breaking the sound barrier is impossible. if the time traveler isn't willing to demonstrate his machine to at least the aero people, if not the general public, then the whole thing is essentially a waste of time.

forgive me for not trusting either john or the physicist.

cheers,
phoenix

PS Zantra where did you go? And who is this pamela character?

I'm still around. Been on vacation for a while. Pamela was the most connected to the John Titor story. Apparently he was communicating largely through her for various things such as the pictures that were posted. She's one of the moderators on anomalies.net
 
  • #65
Yes indeed, John Titor was, at least in my mind, sufficiently debunked. By a Dr.Robert Browne from Duke university. People were going crazy contacting people about this. Even Stephen Hawking was asked about this, though I don't think he replied.

Then apparently Pamela, who was the only contact JT used, and Darby, another moderator, received information from a "friend of a friend" of the person who was portraying John Titor, confirming that it had been a hoax that got out of hand. I guess in theory there's still a possibility that he's real. About the same way there's a possibility the loch ness monster still exists.

If you consider the whole concept, it's brilliant, yet flawed at the same time. Go to one of the few places on the internet where you could convince people to take you seriously as a time traveller, then construct a very solid story as you go, complete with very believable psuedo physics, then skillfully manipulate answers to your questions to aviod making specific immediate references, while making broad predictions about the future that are close enough to take seriously, but not close enough to be tested while it's still an issue. Kind of reminds me of the John Edwards debacle. Psychics operate on many of the same principles. Not sure what the picture of the time machine was. Old military gear is the common theory. The rest of the pictures could have been creatively edited with photoshop. If I had the time on my hands, I could probably create a picture of me standing next to the time machine.

Putting aside the validity of this whole issue...

...if he's the true thing, this is EXACTLY the sort of attitude they would want people to possess, so he would just "go away".

Regardless if he's true or not, the underlieing message he brings is a fair warning for us right now to be mindful of how we conduct ourselves in the future. If he's not...then who cares. Let people decide for themselves, and if they want to believe, they can create a religion or something.

I tend to agree. However, the links that tend to note he's a hoax have been erased or otherwise censored. Is this by design? Most likely.

It is such a devilishly brilliant concept, and the implementation was very convincing. I'll tell you why.

His dialogue is very forward and down to earth. Whoever was posting this honestly believes in himself, his beliefs, even his history. He's either a whack job, or the real thing.

He makes no promises. Which gives him a convenient out, should things not happen. Considering that genetic convergence of 1% of or less can create birth abnormalities and changes, I can imagine what a quantum divurgence of 2.5% would create.

His whole mission is so ludicrous, it's believable. And directly unbelievable at the same time. Easy to dismiss...which gives it some credence. I've seen situations where old, obsolete hardware is powering multi-million dollar facilities. Basically the thinking is, if it ain't broke, it works, why fix it. Pencil detonator's for explosives are akin to this...there are fancy great new electronic detonator's, but they don't always work. 3 Pencil detonators are guaranteed to work. Don't ask me how I know that, I'm ex-Military.

The purpose for him retrieving the machine is not to use it...BUT that it is simply a tool that can read some arcane code. Given the state and the politics of the world, experts are probably few and far between and backyard mechanics are probably here and there. However...you would think that there is something more to the issue. The US Military is embarking on this mission...you'd think they'd have someone that can code in the various languages this machine can interpret and translate...UNLESS there are other languages not acknowledged. Or, of course this is entirely by design. A harbinger.

He's not a scientist. He's a soldier. Take a soldier. He can shoot his rifle, he can clean it. He can even take it apart. He can even be told the physics of how it fires, reloads...etc. But does that mean he'll retain it all? Will he be able to argue the exact tenets of theories, equations, and crap. A lot of the science that is supposedly debunking his own science is premature, and some of it is wrong. But it's where we are now, and we won't be any more advanced until we reach into the future ourselves...at one time we thought the world was square, the center of the universe, and man would never be able to fly, let alone land on the moon...

John Titor's story threatens people. It gives them a glimpse of something uncomfortable, and gives it to them in a meaningful, purposeful way. It also threatens the government. Believe me.

We don't have the specific science to 100% discredit him, and given our advances in science in the last 40 years, who's not say our entire quantum world won't be turned upside down. Tesla was an amazing man. You should do some research into him and the general inaccuracies in the current electro-magnetic theory. If he lived today, he may very well be a John Titor. www.cheniere.org

We also have no indepdent, verifably way to confirm if his science is flawed. According to him, at or about this time (3 years into

With 2.5% divergence...September 11th very well may not have happened, or the previous nuclear disasters may have overshadowed this. It's 25 years in the future, after all. Do you remember the Boer Wars? Grenada? Panama? Even the Gulf War? Thus because he does not come up with exacting and relevant conclusions, doesn't mean he's a hoax, either. Given the issues in the Middle East, I would say that's the first step of him being on-track.

Where do we go from here? True or not, I'm leaning a little bit to the hoax side myself...however if his road map falls out, it'll be interesting to see what happens. His message is a warning for all of us.

If he's wrong, even better...but what will the alternative be? It could be worse.
 
  • #68
Well for those who still hold a degree of acceptance for his claims, there's nothing to do but sit and wait for 2005. Waco/Ruby Ridge type incidents occurring, and escalating until we are engaged in full civil war in 2008 is kinda hard to miss. Of course there were also those proclaiming doom and gloom surrounding the millenium, and it didn't happen. Nothing to do but wait.
 
  • #69
There's a bit of leverage in this scenario. Even if we don't see it, there is going to be some sort of cataclysm. Even this 2015 cataclysm seems to come directly out of left field and probably isn't even related to the "civil war".

But it puts every one on the same page.

Hi Rick,
First, thanks for posting. Have there been any serious efforts to debunk this guy? For example, I suspect that his time machine GE/C204 is a mobile receiver unit used by the military.

Iva - some "debunking". Not really anything serious I would say. Most folks have taken a "side" in the issue and most generally I would say everyone has an opinion, scientific or not, but rarely has anyone posted (anywhere to my knowledge) anything other than firm "opinions". My own included in that for that matter.

Pesonally, I have spent a lot of time going through his previous posts of the first couple of years when I wasn't actually involved in communication with him, and I took some of his material and set up an "experiment".

I'll give a few details here.

First I ASSUME for the sake of argument that John Titor IS a time traveler, and second that he is "telling the truth" about everything he says.

Secondly, we took his statement of "I will NOT make ANY predictions" to heart, and assume he makes no "predictions.

Thirdly, since the first and second things above we're assuming are true, we asked questions of him. People asked things like "What is your world like".

Those answers while not "predictions" per se, are statements of "fact" as "he knows it". In other words, if he IS from the future, and he IS telling the truth, and his time line is NOT MUCH different from our own time line, it stands to reason that anything he is telling us is reasonably OUR FUTURE (with some deviation, of 2.5% or so - more on that later).

Thus, we have statements of "fact" about what something is like in the future. This defacto becomes a "prediction" - not in the traditional sense, but a prediction nonetheless.

I took about 100 statements he made and listed them as "predictions". These were statements about how such and such a thing was, or will be, about the nuclear war, the "Waco-like incidents" and so forth.

No where did I find anything about stockmarkets, 9/11 attack, or something like that. Just random, real statements about what the future is like from his personal point of view.

My hypothesis is "John Titor is a Time Traveler" and the proofs will be in the statements, at least on a semi-scientific study of those things he said.

For instance... if 97.5% of the list comes true, then without any doubt in my mind I can say "John Titor is a time traveler". If anything less than that amount comes true, say 85%, then we can say "John is likely a time traveler". If 50% or less comes true we can reasonably say "John was NOT a time traveler".

Here is where I got the numbers.

In the discussions of the time machine there were some "deviation factors". The further you traveled from your origin (2036) the greater the deviation. At 76 years from your point of origin, the actual "time line deviation is 2.5%". Without having much further information than "things start happening differently" (one of his statements which comes to mind) and "the further beyond 76 years, things get weird" (to paraphrase since I don't have the actual material in front of me) I can ONLY make a wild assed assuption here.

That assumption is that any given thing has a 100% chance of happening "again". And the further you drift from a given time line, the more changes will happen. That is, things WON'T happen as they did in say, our time line. (I hope that is clear).

I took 2036 - 76 and that gives me 1960. So if he traveled back to 1976 then things would have been "weird". So, we will assume WORST CASE. That is, he has at least a 2.5% deviation "factor" from his actual time line. That means of 100 RANDOM things in his time line only 97.5 of them will occur as he leaves his time line (left it, is going to leave... whatever!).

Ok... So... IF John is a TT, then all of the things on that list I typed up long ago ought to occur.

The problem (one of many) is that many of those things were somewhat subjective. That means that even if this were a true scientific experiment (which it is only as close as I could get given the circumstances) then if he is a TT they will come true. At least 97.5% of the 100 things will. Anything LESS indicates that he probably is NOT a real time traveler.

About the Time Machine... I am a 26 year military veteran. I'm a radio guy by trade. I'm familiar with nearly every sort of radio system the USAF uses anywhere, and most of the Army's gear. I'm familiar with a lot of other radio gear because I've been involved in radio for well over 30 years personally.

In the images we received that were from John, of the time machine, there were things in the images I DO recognize. One is a small yellow box with a big dial on it. That was a geiger counter. I was very familiar with that particular device because I had several of those in some of my old tactical gear many years ago.

As for the time travel "device" itself... I have been unable to find ANYTHING that even comes close - except the external box itself. Someone else (whose name escapes me) actually found a box like that, painted green, made of high impact plastic and is precisely what the military uses to house certain types of gear. Generally gear is transported in them, and not installed as this TT device appeared to be.

In other words, I do not personally believe that the time travel device is actually some other piece of gear that has been modified to look as it does in the images. In other words, it isn't some piece of gear that was made for some other purpose.
Whether or not it is REAL - I can't say. I CAN say though that if I wanted to reproduce a device that looks like that thing, and appears to have some functions, I could do so. I am an electronics engineer.

On the other hand, the schematics I saw, limited as they were had some very interesting aspects to them,and from both an electronics engineering standpoint and physics standpoint they were well drawn (or thought out) and DID indeed APPEAR to come from scans of an original manual.

Other than that, I can't say for sure they were real or hoaxed. If they are a hoax, they are well done.

Now... for the record... and published for what amounts to be the "first time" even though I've said this in chat rooms...

Personally, I do not believe John Titor was a time traveler. I believe he furnished a well done "history", or "psychological study" of the human mind though. He was either a very good SF writer, who was practicing on the rest of us normal humans, or was doing this out of sheer need to attract a large amount of attention. Apparently he did.

On the other hand, being open minded, I will say that until someone proves it absolutely to have been a hoax (with honest records, and hardware - say, the time machine itself) then I will not close out the possibility in my own mind that he was real.

A "true debunker" will have an eye for finding pieces of the puzzle that do not fit, not showing the guy was "an idiot" or "anyone that believes him is an idiot" etc. I've seen WAY too much of that over the past few years. Instead, a real honest to goodness "debunker" will find the parts of his "science" that are wrong. So far, I've not seen anyone do that, not anywhere. Then again, I've not seen everything written on this subject yet and it grows daily. Perhaps we will never know... for sure.

Opps... saw a mistake.

In my previous post I said:

So if he traveled back to 1976 then things would have been "weird".

Should read:

So if he traveled back beyond 1960 then things would have been "weird".

(If he only traveled back to 1978, or 76 or so, then things would be exactly the same in his time line and the one he "landed in".)

For those of you who missed this, someone contacted many scientists. One who actually bothered to reply was a physicist from Duke University, and he went over the flaws in his explanation of the workings of his time machine, and the inheirent flaws in such a device

This is his response, posted pretty recently.

By the way I don't like what Titor is doing. He appears to be practising mass hypnotism on people. He gives a few 'prophecies' of things that Titor knew would probably happen anyway. Then he describes a simple way to build a time machine. Some people want to believe in a time machine so badly that they go along with his suggestions that he knows the future and they expect it to really happen. Other people are shocked into suggestability by fear of the future.

I believe Titor's secret agenda is to start a war. Be careful about being taken for a ride that ends in disaster!

Tidor said he had personal rules that he followed unless they conflicted with his secret agenda.

Tidor said that building a time machine was the best way to start a war. (I don't see how he could have known that since he said the machine was built in 2034 and there was no war from 2034 to 2036).

Tidor gave a description of how the time machine was built. He seemed to be telling us how to build one.

He said that we would be better off if half of us were dead.

He said that he would not try to stop the war but we could yet probably wouldn't.

He said that in 2036 that people hated us.

As TT0 he said he personally hated us. He even blamed us for the death of his fiance who died of cancer.

I used the term mass hypnotism because that appears to be the effect he is having on some people. Would you prefer the term psycological terrorism? Tidor was very smooth in answering questions and covering up inconsistancies. Saying things like they use manual typewriters because computer printers did not work well on 12 volt batteries. The lifestyle he described in 2036 sounds like a struggle to survive. Living in tree houses and fishing for a living. How could they be developing the technology needed for building time machines?

Do you choose to believe that Titor's story is true and that he is a real time traveler?

I believe that he is conducting a well prepared experiment to see if he can change the future.

May be that Titor is just trying to influence the 2004 election. If so what party do you think he is favouring?

That sounds better at least than Titor trying to start a war on purpose.

i don't think the best way to start a war is on discussion forums.

i would blackmail a (group of) translator(s). so the next time the dude says "we come in peace" the translator can say "you will kneel trembling before us and obey my brutal commands," although it might be confusing as to why there were so many more words in the translation than the original... I'm sure such loose ends could be tied up.

Time Travel it's bout as logical as space travel

It is possible that a person was sent here to prevent some great catastrophe, but let's just be real. B.S military documents and pictures of some contraption you would find in radioshack(a well stocked Radioshack). We are sceptical by nature that's why there are Physics Forums. Our future military would have sent more stuff with him than a manual. Time Travel Yes Titor No.

But if?

But if that Apache Pilot fley back in time to WWII With information from the future the craft itself would be evidence. John Titor Had a shot Gun(not even a good one just some old chrome sawed off pump) and a Corvette. I can soup up a vette. Also he would know how his vehicle worked so he could fix any problems that would prevent his return trip. At least Smart Guy would.

I guess it would be fun to live in the imagination. As long as you were able to return back to the real world. Then you would not need a time machine.

Thinking about Titor ...

In my unlearned opinion, Time Travel is impossible and will always be (confined?) in the realms of Science-Fiction and flights of imaginary fancy.

TT is like the Fermi Paradox concerning the existence (or not) of ETs. If Men from the future can travel backwards in time then they would surely be here by now. Of course, this doesn't take into account the possibility of multiple timelines!

Some points to consider against the likelihood of TT:

1. Fact - The Universe is continuously expanding. Theory - The connections between superstrings must be expanding accordingly.

The atomic structure of a Time Traveller from the future would be comprised of 'larger' superstrings. Therefore, his very appearance in an earlier (smaller superstring) era would create a shift in the universal equilibrium, with possible devastating results for all.

2. Fact - As space expands, the Solar System is continously moving - and pretty darned fast too! Any Time Traveller coming from even a few days into the future (let alone three decades as Titor claimed) would find himself stranded in space (unless his Time Vehicle is a spacecraft too - and not many Corvettes are!).

3. Fact - The Time Traveller is comprised of matter. Matter redistributed by consumption/absorption et cetera from other external sources (we are all made from starstuff!). This matter would exist in a different form prior to the Time Traveller eating it. This different form would exist in the Time Traveller's past (our present). Which means upon appearing in our time, identical atoms would suddenly exist in two places at once! Paradox! Our universe would suddenly contain MORE matter than it did a moment before. Since matter and energy are inter-transferable, this would destabilize the universal equilibrium, again with untold bad results.

4. Fact - Nature likes balance. Moving matter/energy through the timeline willy-nilly would go against the grain. Chaos would surely result, and we all know nature cleaves to order. Theory - No Creator in His right mind would allow it. I wouldn't!

what's your definition of time travel?

ever heard of time-dilation in special relativity? perhaps you have but that doesn't fit your definition of time travel.

to me, "proving" a feat is impossible based solely on a finite amount of past experience is risky. in other words, arguments like feat X has never happened in the t years I've been observing the universe implies that feat X will NEVER happen. i'd be much more inclined to think it may be very unlikely but not neccessarily impossible.

does "event A is impossible" mean that P(A)=0?

if P(A)=0, A is still possible. for example, consider flipping a coin infinitely many times. consider the event that all results are heads: A={heads, heads, heads, ...}={a_n} where a_n=heads for all n. P(A)=0 but it is still possible that it will always be heads. actually, any outcome has probability 0. {heads,tails,heads,tails,...} also has probability 0 but it could still happen.

i'm guess that by impossible, you mean that literally.

... mmm.

My references were strictly restricted to the macro-universe side of the time travel fence.

Time is relative - so in a sense everyone and everything is time-travelling in it's own subjectivity.

I didn't literally mean that because I (or we) had not personally witnessed a time traveller in our years of observation that that was my 'proof' discaliming time travel.

What I meant was, that if you think of time as a two-way street then someone ought to have traveled back in time to our era by now and proved it's eventual invention (or discovery) in some far future.

It's common sense, as I see it.

Surely, if time travel was a reality in the future then surely some unscrupulous individuals would steal the technology and use it for their own ill-gotten means. This is the nature of Man. Since our history so far has not recorded any such events (that we recognize as such) then it is fairly likely to say that no-one has traveled back in time to any period prior to our present - or else we'd have evidence to some degree or another.

this is an argument stephen hawking mentions as well.

i'm not sure how old mankind is. in other words, I'm not sure how long homo sapiens have been around. and how long we've been using language, tools, etc...

but let's say that homo sapiens has been around since year x. i would guess that (2003 - x)>15000 but I'm not sure.

let's pretend, for a moment, that time travel, back and forward, is possible and it gets invented in the year 2003+y, y years from now. the set of times for which mankind will have existed by then is
[x, 2003+y] which is the same as [x,2003]∪[2003,2003+y]. the age of mankind by then will be 2003 - x + y. just for the sake of making a calculation, let's say that the probability of a time traveler coming from a year in [2003+y,∞) to any specific year in [x, 2003+y] is equally likely. to say it will be more likely to come in [1900,2003+y], for example, is to guess what time travelers would be more interested. although by that argument, it's also a guess that any time travelers would be interested in the interval
[x,2003+y] and not something before that. so let's for the moment pretend all years in [x,2003+y] are equally likely to receive visits from a time traveller in [2003+y,∞). then the probability that a time traveler will visit any particular year, decade, and century are given, respectively, by
P1=1/(2003 - x + y),
P10=10/(2003 - x + y),
P100=100/(2003 - x + y).

i think it's pretty safe to assume that 2003 - x > 15000 and y > 5. this gives upper bounds on P1, P10, and P100:
P1<1/15005&asymp;0.0000666445
P10<10/15005&asymp;0.000666445
P100<100/15005&asymp;0.00666445.

for example, the probability that a time traveler visits the 21st century is less than 0.007. and this was assuming y > 5, time travel is invented only 5 years from now. it could be that y>10000 which would lower the upper bounds.

however, this is only the probability that one time travler visits a time in the interval [x, 2003+y]. there could be, of course, a googleplex of time travelers coming from the interval [2003+y,&infin;) which would raise the odds of there being at least one visitor to a random year.

the probability of there being at least one is equivalent to there being 1 or 2 or 3 or ... time travelers. then the probability of there being at least one time traveler to any given century would be approximated by some infinite series:
P100(n&ge;1)=SUM[ (100/(2003 - x + y))n : n&ge;1]. this geometric series has sum 100/(1903 - x + y) if i did all the math right. this isn't hugely bigger than 100/(2003 - x + y) since the odds of n time travelers visiting a particular century get lower when n gets larger. assuming 1903 - x > 14900 and y > 5, the probability that at least one time traveler comes in any particular century is at most 0.00670916. at most. now if y is much bigger than 5, in other words if time travel is invented more than 5 years from now, the upper bound lowers. if y>1000 then the new upper bound for the probability of at least one time traveler coming to any particular century is 0.00628931, about one-sixth as likely as getting blackjack in one game of 21.

therefore, the argument "why haven't they come yet" is not something that i put much stock in.

I guess the best answer is to just sit back and wait.

I decided to write down his predictions, if they come true then i'll start to think about it.

Nonsense!

I haven't read this entire thread yet, so please forgive me if I am saying something that has been said already.

There is one simple reason to not believe that this is true.
He claims that the multiple worlds theory is true.

If the mulitple worlds theory is true, wouldn't time travel (especially with the intention of "warning" us about the future to come) be completely pointless?

If the multiple worlds theory is true, then there are in infinite number of worldlines existing simultaneously, and an infinite number constantly being created.
If he traveled back in time, what would bring him to this particular worldline?
Why?

If every possible outcome WILL happen what is so special and significant about THIS worldline?

If he is a soldier, the military would only send him back if he had a specific purpose (such as to prevent this nuclear war), but.

Regardless of whether or not he stops this event in X worldline it will still happen in another. What is the point of creating a new worldline in which it doesn't?

Whatever he does, whoever he convinces, there will be no effect to his traveling back in time, so there would be no point.

In the many worlds scenario, you can't go back and change the past, you can just go back and create new worldlines.
It is similar to going to the beach and dropping a pinch of salt in the ocean.

The event would still happen.
He would just create a new worldline in which it doesn't.

Multiple worlds - what are the chances

one_raven: I don't agree with the "what are the chances" argument, because it's like denying the possibility of winning the lottery based on probability when you're standing there with the cheque for $1m :)

I stumbled on the whole John Titor thing a couple of weeks ago and it was a very interesting read. I tend to think (and Occam may agree), that it's most likely to be a physics grad with lots of spare time having a bit of fun with the Art Bell crowd... however if you treat him as a social observer/commentator then he raises some very valid points. Our society so needs what he described.

I'm only an armchair physicist, so I can't really comment on the whole time-travel mechanism he mentions. All I can say is that he doesn't stoop to "movie-like" time travel - brilliant spinning vortices of light, star-trek warp drives, Delorians and flux-capacitors - which indicates that (assuming he's a crank) he's put a bit of thought into his story.

Titors stated reason for "travelling back in time" was that he needed some computer thing, not to stop the war or whatever he claimed would happen by his time.

This has to be false, use common sense. Our current generation, "The Hip Generation", won't talk like this idiot did. His post would be more, like fo shizzle, ya'll be some wacked fools to believe all dis hype, you know wat I'm sayin:). Note the shortening of words and the continuing trend for language to change, his language was much too 2000ish!

Interesting.

There is also the amazingly obvious point of why on Earth any time traveller would expose himself so publicly.

Any half moron would try to avoid being discovered - not go out of his way to broadcast his existence!

I'm afraid old John was yet another false prophet - fitting for his timely arrival at the turn of the Millennium.

John Titor is a mind control technique used by the original Illuminatti to start a civil war.
Be aware.
