Hey guys, I'm thinking up some time travel science fiction ideas, but I don't know if I've made it overly complicated.

​

If you have a spare moment, could you guys read this, see if it make sense and feedback to me?

​

Ok so let's say we have Person A...

​

Person A is 25. The current year is 2026. Person A goes back in time, 26 years ago to the year 2000, and stops a car accident from happening. What they don't realise is they accidentally change so much that Person A's parents never meet, so they are never born.

​

They go back to the year 2026. Person A sees there is no records of Person A anywhere - they do not exist anymore. But how are they still alive (questioning the whole Grandfather paradox)? They soon realise they have haven't changed their original timeline; they just created a branched timeline instead.

​

Let's call the original timeline, Timeline 1 and this new branched timeline, Timeline 2.

​

They hypothesise that Timeline 1 still exists and maybe still continuing on, just without Person A. Maybe they could be a missing person in Timeline 1.

​

Person A comes up with an idea on how to return. The only way to get back to Timeline 1's 2026 is go back to the point it all changed.

​

To do this, Person A goes back to the year 2000 to prevent their past self from changing things. Let's call Person A's past self YPA (Younger Person A). Person A tells YPA of the consequences of changing time and convinces YPA to go back to 2026 without changing anything.

​

Once YPA time travels, Person A goes back to 2026 - now back to Timeline 1!

​

HOWEVER, when Person A arrives back to Timeline 1's 2026 they also find YPA - the exact version of themselves they had just convinced to not change time...

​

Let me know if you guys follow, or it's just overly complicated for the sake of it.
