Hello, My friends and I have had about a 3 month dicussion going regarding time travel.We have to get this right. Its also something they have been debating on their podcast. The question or arguement is. In the movie "Back to The Future" Marty goes back in time from 1985 to 1955.which after many events he must go back to the future. The arguement is that according to our friend Ully he, Marty CANT go back in time because he goes back to HIS present. But what we argue is that hes going to the future of that time line from 1955. He says the movie title is wrong because Ully says that Marty goes back to his future. Since he cant Return to the future because it isnt his future. We argue his goes back in time in that universes timeline. Then in that time line goes back to the future after the 1955 event. To a future moment of that said timeline. Not martys life.
