I have a theory. You know how in time travel back in time, if

If you really would like an answer, elaborate more.

Even if you time travel to a point before which you time traveled before, you're still on a timeline in which after you arrived, you arrived again and did whatever you did.

So if you altered the spacial timeline through back in time travel you create an alternate timeline, your original timeline still exists. you just aren't in it anymore since you changed things.

if you timetravel back before you altered the timeline you are now back in your original timeline. Which means if you just time travel back from that point you are now back in the timeline you came from.

I dunno, maybe that timeline is still created and exists and repercussions on if this is true is that time travel exists and there are currently billions of timelines and we just don't notice.

Of course, but the timeline you travel on is based on the current series of events you are on. That's why, when you travel back to the future, you end up on a different timeline. The series of events have changed.

So, the same applies when traveling back in time as well. When you go from the current future to the current past, you do it all on the current series of events. That means, as you travel back in time, there is a point at which you pass the point where you arrived before. And, because you haven't actually changed that series of events, that means you're still on that series of events. So, that's still the same future you'll go back to. All you've done is paced back and forth on the fourth dimension.

Of course, this is where the logic of most time travel fictions break down. Not because of any paradox, but because of the inconsistency in logic. If you traveled back in time and changed something, then that happened even before you traveled back in time in the first place. So, nothing in the future would change because it already happened. Even by the logic presented in Back to the Future, if you're traveling on a single series of events, then you can't possibly change anything. The point at which you travel back and change things was already on that series of events. If it wasn't on that series of events, then it's not an event that happened. Thus, you couldn't have traveled back to it.
