So having explained all the possible timelines, there is also one major alternative…which is:
Doc Was Wrong About Alternative Timelines
Young Doc talks of things being erased from existence. Old Doc talks of alternative timelines. Whilst we have explored how both can be true in this article, it is also possible that old Doc could just be wrong. We definitely do see what we can interpret to be changes in time at various points in the series. Objects like photos or newspapers changing and people vanishing. The alternative timeline of the Powerful Biff timeline may not be an alternative reality and may just be a reflection of time being changed.
That Jennifer can be on the porch and remember the exact events of 2015 that the audience witnessed despite her not continuing to travel with the Doc and Marty is huge evidence that time changed and evolved around her, and that she remained the same.
So maybe Doc was wrong and there aren’t multiple realities and instead there is one timeline which can bend out of shape and be tweaked for better or worse.
What are your thoughts? I’ve tried to present a balanced argument where we can examine evidence on all sides here, but feel free to put in the comments your own theories or if there are glaring holes in this argument!
