The Grandfather Paradox

So, I happened to be reading a book the other day and it mentioned the Grandfather Paradox. I was surprised to see that what i believed is actually a theory that many people recognize. It's called the "Many-Worlds theory". The theory states that the paradox isn't a paradox at all.

Every time you make a decision, an alternate reality gets created. If you decide to write in black ink, a reality is created where you use blue ink. So once you kill your grandfather, you are immediately in an alternate reality where you've done it. You no longer exist in the original reality that you came from.

I thought the grandfather paradox was that if you went back in time to kill your grandfather that you would no longer exist in the future, thus you would never have been able to go into the past and kill your grandfather which means that you would have been created and could go kill him.... etc.

This continues in an endless loop.

It basically means that time travel is impossible because all effects of the past would be negated by their future effects and you would be stuck in a loop.

I suppose that the many-worlds hypothesis counteracts this because instead of getting stuck in said loop, you create a whole new universe. Would you be stuck in the past in the new universe?

In the future of that specific reality that you killed your grandfather...you wouldn't exist. But you'd create the reality where you did, and exist. You'd never be able to get back to that first reality, though. You don't exist there.

parallel realities are part of another dimension there are some good videos and books that explain all other dimensions up to the tenth dim. another video is called God 2.0 which talks about how God is just the randomness and string of all events because its everything.
check 'em out.
