Or is it just a plot for a movie.

There were a few shows on Coast To Coast A.M about this guy, photos of his 'time machine', logos and symbols.

sense none of his predictions have come true, i would have to say no...unless he changed the past....

Wait...you mean there wasn't an American Civil War in 2005?

This was just some guy goofing off on Internet Forums about time travel.

I got the following from the Wiki link you provided:



Well, that pretty much sums it up don't you think?

If John Titor truly was a time traveler who understood the Many Worlds interpretation of QM then he'd know better than to even remotely think that he could predict the future for any individual since everyone's future is ultimately different in the Many Worlds interpretation of QM.

Yet, he continued to spout predictions anyway? What sense would that make?

Also, if the Many Worlds interpretation is correct, then from the same reasoning, when he traveled into the past he could not know if the past he travels to was the same as the "past" that led up to his "present" time.

In fact, if the Many Worlds interpretation of QM is correct then any sort of "Time-Travel" would be totally pot luck. In other words, even if you could travel into the "past" it wouldn't necessarily be a "past" that had anything to do with your "present" time.

So as soon as the Many Worlds interpretation is tossed into the mix then the very notion of "prophecy" or predictions of future events goes right out the window because it would be impossible to predict which future any particular person is going to experience since everyone experiences all possible "futures".

Although, I must confess that I personally don't buy into the Many Worlds interpretation of QM to begin with. There are many problems associated with that idea, and in the end, the only reason the idea was "invented" was to "salvage" a notion of pure "cause and effect" without violating the limitation of the "Speed of Light".

Just to save those ideals, we end up with every possible future that can be imagined actually unfolding.

That's a big price to pay just to save a "Newtonian sense" of Cause and Effect.

There are far better interpretations that also save a "Newtonian sense" of Cause and Effect. The most popular of those being the "Hidden Variable" interpretation which simple allows for "Faster than Light" knowledge to propagate "Throughout" the universe. Although not necessarily "Through" the fabric of spacetime. In other words, if this is done through some extra dimensions that exist "Outside" the normal 4-dimensional spacetime of Relativity then such super-luminal communications would not violate Relativity.

In any case, Titor cut his own throat when he suggested that the "Many Worlds" interpretation is correct, because that would automatically make it impossible for him to "predict" anything. Yet he did give predictions thus violating his own scenario.
