> In order for Marty to go to the future and see himself, he'd need to continue to exist in 1985 somehow. I'm not sure how to reconcile him getting into the DeLorean with Doc and yet simultaneously going back into his house to live the rest of his life normally. This is something I've mentally struggled with since the second film came out. His leaving 1985 temporally is an exit event; he ceases to exist in his own timeline. The only explanation I could come up with is that he does indeed visit an alternate timeline where Doc never created the time machine and therefore Marty never goes back in time to "fix" his father's resolve. There are hints about that; Old Marty is still unsure of himself and allows his boss to run all over him, his son took on his and his father's bad traits, etc. The only way this works is if Doc is unable to visit the same timeline going forward, and can only do so going backwards. The problem becomes, if every forward time travel event leads to an alternate timeline (as is necessary for existential reasons), and any changes made to his own past timeline also cause a new timeline to branch off, why is Doc so worried about fixing the past in order to fix the future? They aren't his past and future anymore, just ones he created by traveling through time in the first place. |

Is it possible that an inventor brilliant enough to have built a time machine doesn't subscribe to the parallel-realities hypothesis, and is unaware of how his invention really works? We'd need to answer this question to get to why Doc Brown cares so much.
