Air Ship From 3000 C.E.
Mac Tonnies has stirred up some controversy with his CTH - crypto-terrestrial hypothesis - over at his blog, Posthuman Blues. Other UFO theories have been mentioned by commenters, including the idea that UFOs come from our future, i.e., mankind advances to the point that it discovers how to travel through time.
Of course, the argument has been made that time travel could never be possible because of the paradoxes involved. For example, you couldn't go back in time and kill your grandfather before your father was born because you would never exist in the first place.
I just left a comment at Mac's blog and I'm also posting it here so that it's less apt to be lost in the insurmountable sea of information that is the Web.

Here's my speculation on time travelers and UFOs:
In the future time travel is possible as long as you don't try to change history. As soon as a time traveler attempts to affect a past event, they are negated, cease to exist.
So a time traveler must fit into what already has happened. He would check the historical record and then morph his time machine into what has already been reported. If he wants to check out the USA in the 1890s, he could make his machine look like one of the mysterious air ships spotted during that period. And if there's a report of an air ship crew talking with someone, the time travelers could dress for the occasion and just say their lines from the historical "script."

You’re overlooking the many worlds interpretation of space/time.
With the many worlds or multiverse interpetations you don’t have to worry about paradoxes such as what happens if you accidentally change history or anything because every possibility at every instant of time exists such that a time traveler can go back in time and kill his grandfather and not impact the timeline the time traveler came from. The bad part is that the time traveler would probably never be able to get back to the exact timeline he left from due to the uncertainty principle. Of course this doesn’t really matter since all you need to do is get close enough to your original universe so that everything is the way you remember it.
But if too many time travelers kept creating alternate universes / timelines, wouldn't that create instability after a while and the whole mess would either blow up or collapse in on itself?
Of course, this is all speculation.
ThanX for your comment.
