It sounds like you are parroting mister bob orci. Who, I am confident to say, doesn't know what he is talking about in this regard.
Based on what you've written in this thread, you have no clue what you're talking about either. So it all evens out.
The difference between past trek and imposter trek is that past trek worked with science, I.E relativity (which, contrary to your belief, is still the most applicable version of how time travel may be possible) not against science, as bob orci and company seek to do.
