Question: So I saw the movie and understood most of it but at the end the man that tried to stop the ferry from blowing up dies in the car. So this means that he duplicated himself. So if they use that machine, could they keep using it to duplicate people?

Chosen answer: He does not duplicate himself. He travels back in time to a point where his past self exists, so there are 2 of the same person. One simply has a few more hours of memories. Yes, in theory by traveling back in time this way, he could create a situation where there were many of him at one time.
