Time travel is a quantum impossibility. While I do believe that viewing the past and possible future, I can't accept the idea that one can
travel backwards in time.
Think of time in this way. There is one past, one present, and an infinite number of futures, some of which are nearly identical, others of which are
entirely unrecognizable. Possible futures are constantly changing from moment to moment with each action of every living thing on the planet. Allow
me to rip an example from the television series, Heroes. Hiro Nakamura is a time-traveller; a version of himself from the future went back five years
in time, and averted a holocaust. His timeline ceased to exist, but his actions which changed the past remained. This in itself is an inexcusable
paradox, which, though ficitional, adequately illustrates why one cannot change the past.
Beyond that, consider the more destructive paradox which would follow. Sticking with my previous example, lets say another Future Hiro came back to
change the past. He succeeds, and creates a new future. In that future, another Hiro comes back to change the past. He succeeds, and creates a new
future. Do you see the pattern? The space-time continuum would virutally disintigrate as the infinite possibilities of the future converge on one
timeline. I know I'm not explaining it very well, but I hope you can understand my meaning. I think we may even be able to move forward in
time, since the future isn't written; a future-traveller would simply be forced to return to the exact point of his departure to ensure that he
doesn't become trapped in a timeline which won't exist. It would be dangerous, but theoretically possible. But moving backwards, if possible,
would be ultimately detrimental.
That being said, I think the philadelphia experiment was a failure in the sense of creating a time machine. I theorize that they accidentally created
a dimensional craft of poor stability, but I can't prove that. Hence, I think this fellow who claims to be selling time machines is full of it.
Whatever he made, whether functional or not, can't possibly be a time machine.
