Talk:Grandfather paradox

message: The below paragraph doesn't make sense to me... The first sentence is particularly confusing. Can someone please shed some light on this or consider rephrasing it?
"One variant of the grandfather paradox is that when the traveller kills the grandfather, the act took place in, or resulted in the creation of, a parallel universe where the traveller's counterpart never exists as a result, but his prior existence in the original universe is unaltered.[citation needed] In other variants, the actions of the time traveller have no effect outside of their own personal experience;[citation needed] for example, in the novel The Men Who Murdered Mohammed by Alfred Bester.[citation needed]"

message: I think I have a solution for grandfather paradox. Once you go back in time and kill your grandfather you actually kill him and remove your own existence as well, that is your grandfather will dead and you will not be born, end of the story. So the paradox of "whether you went back in time and killed your grandfather or not, or whether you were born or not" doesn't apply. So there is no argument of " you go back in time and kill your grandfather, thus aren't born, thus you cant go back in time and kill him, thus your grandfather isn't killed, thus you are born so you can go back in time and kill your grandfather and so on", because as I said when you go back in time and kill your grandfather this will be the end for both of you.  — Preceding unsigned comment added by Mohammad Zuaiter (talk • contribs) 10:57, 22 September 2017 (UTC)

message: There is nobody who have undergone something like Grandfather paradox, hence can't be predicted. May become as a theory from paradox, "as future is not carved in stone". Shivanesh77 (talk) 15:20, 24 August 2018 (UTC)
replies: text: Please discuss the article. Your two short sentences contain several mistakes (for example see history of general relativity for amazing predictions that were made before anybody has "undergone something like them") and they don't directly address any problems with the article.

message: There's a new article (Baumeler et al, Reversible time travel with freedom of choice, 29 October 2019) which concludes that "consistency with local operations is compatible with non-trivial time travel". Likely worth mentioning it in this article. --Chris Howard (talk) 20:29, 3 November 2019 (UTC)

message: The thing is, if you go back in time to kill your grandfather, that means you never existed. If you never existed, you can't go back in time and kill you grandfather, so he's still alive. If he's still alive that means you get born. If you're alive you then will kill him, which means he's dead and you're back at the beginning of the cycle.
