We are all time travelers - as we are all traveling through time in a linear fashion. Oops. And unfortunately - I do not believe there is a test one could administer to see if a purported time traveler is telling the truth. In this day and age, almost anything can be faked.I think the major flaw in my test is that no one knows if there was any collusion between you and I making it appear that you passed the test. Of course you and I know the answer to that. With the odds being infinity to one against you. And then there is the sudden reversal of you claiming now that you are not a time traveler. Most time travel claimants want everyone to believe them. But not you. Oops!
