Leena,

You're absolutly correct about the observer in a "reverse time" universe thinking that time was progressing foreward. Time, afterall, is relative to the observer.

Einsteinian physics has this same set up. If you are traveling faster then people around you (we're talking much faster...not just relative earth speeds), time changes. For you, time is the same, but for those people observing you, you would have slowed down. However to you, those people who are traveling SLOWER then you have actualy "sped up" in time...and would age quicker.

Quirky? Yes, but's it's been proven to be true using atomic clocks in orbit (and traveling far faster then syncronized clocks on earth). They will actualy move slower...but to the astronaughts, they are keeping perfect time.

So time is relative to the observer, moreso, if we are traveling backwards through time...which who knows...we could be, those in a reverse time universe wouldn't know that they are traveling backwards.

Let that cook your noodle for a while.
