The Grandfather Paradox

The most mind boggling paradoxes of all time; the grandfather paradox deals with the repercussions of time travel.

The grandfather paradox is a paradox of time travel in which inconsistencies emerge through changing past.

A person travels back in time to the past and kills their grandfather before the conception of their father or mother, which prevents the time traveler’s existence. HERE LIES THE PARADOX.
The first solution to this famous paradox is that when you go back in time to kill your grandfather, you’re not going back to your own history, but a copy of your history, and everything you do in this version of your history will affect the alternate future of that universe, not your own.

Think about it. All your atoms are scanned and destroyed in the process, because there’s no cloning allowed in quantum mechanics. Then all that information about you is teleported to the new location, where a bunch of new atoms are used to build a whole new you, complete with memories, personality quirks, and that oddly shaped birthmark on your left butt cheek.

Basically, if you go back in time and kill your grandfather, you don’t exist, so your grandfather can’t be killed. So there are two realities happening in parallel here. While all of this is 100 percent hypothetical, because no one’s actually gone back in time to test this out, we do have evidence of two separate realities happening in parallel.

  1. Unless you go back in time – kill the grandfather and find out his wife was pregnant at the time with his baby or was pregnant at the time with her lovers baby and after her husband is dead she’s like phew got out of that mess and says it was his baby so her mother in law never knows. The paradox is mind bending when you start trying to work out logistics – great post!!

  2. I am with the two separate realities happening in parallel. Onecomment and a question. Comment, I think we live a parallel existence now. One on the inner and one in the outer, primarily due because the outer needs to behave in order to survive, while the inner is eternal, no need to invent behaviors.
    Question, why can’t we clone in quantum mechanics?
    Thank you for your time and post!

    1. In biology, cloning means having exact same DNA. In quantum mechanics cloning means to replicate the object to the subatomic level. The rules of quantum mechanics say that cloning the entire object all at once and cloning it piece by piece should produce the same result, but when you do the math that doesn’t happen. And moreover in quantum mechanics cloning u have clone every single particle and predicting the momentum, velocity etc. of all the particles is pretty much impossible.
