Assuming that time travel does exist...Is there any way that we might be able to ID a traveler?

Question

We as a society are quick to dismiss anything that we have no direct knowledge of. We love to point fingers and label people kooks and the like. How do we know if there's a way to positively ID someone that is indeed a time traveler (assuming that time travel exists?)

Look at the story of John Titor. Who knows what's real? How would you be able to tell?

Answer 1

A time traveler will always be able to tell you what you are about to say.

Did I say that?

Answer 2

It is impossible to travel into the past. Any slight fluctuation in the retroactive (backwards) course would create another time line. And since you are a new presence to the past that has elasped, your very being would create another time line. The elasped past is naturally "timelocked" and cannot be accessed. All time travellers must therefore be strangers from other time lines....

But that does not mean you could not travel to a time line that was very similiar to time lines that transpired in the past. You could visit a place where the civilization of Rome was present, or go back to the days of the Stone age. It would be very similiar, but not exact. It is required to be only off by one fluctuation. These fluctuations must occur while a person is in transit, or from their own body and mind. When a person arrives at a time line that was elasped, he creates a new time line at the point of his entry. There is no such thing as a situation where the past can destroy the future, that is determinism. With such a model, you arrive at paradoxes where someone "MUST" do something in order to satisfy a time line. One example is when a person plays a part in past events where their participation is essential to a resolution of the events, but the person knows beforehand that they were involved. This negates free will and is a fantasy. It assumes one past, one present, one future. Multiple universe theory explains that there is no paradox needed---paradoxes are resolved by the many worlds theory.

John Tidor was a stranger from another time line. There can be no other conclusion. He cannot know what events will happen in our future because from his perspective, they have not happened yet. When he arrived here, he created a new time line, and new events would happen in his future....

He could come from the future, A FUTURE, rather than OUR FUTURE. He also may have travelled to A PAST, rather than HIS PAST.

As for ID'ing a time traveller, you might want to check his technology or take a peek at his method. Could be useful.
