If somehow I go to past and kill my grandfather before my father was born then I did I kill my grandfather?

[Daichi]

This is a paradox which have puzzled me for years. Anybody have any possible explanations?

You just created another universe where your dad was never born, and neither are you. It has to be that way because you cant have no origin. You need to have been born to kill your grandfather. So your universe isnt effected. Its like the whole thing with Trunks going back to kill Cell. His world didnt change, but there is now a universe where the z warriors defeated cell.

The only other explanation is if by going back in time you removed yourself from time and now exist outside of time, meaning you arent effected by changes in time or at least the time stream that affects your own birth.

Yes, if you kill your grandfather, you have killed your grandfather.

...I either don't understand what you're asking or you messed up your question half way through.

His question is essentially that if he killed his grandfather before his father was born, he can't exist since there's no one to give birth to him so if he didn't exist, did anyone kill his grandfather? It's a paradox. I agree with what Cupcake said.

 

[PrincessFelicie]

Then the answer is we just can't know yet. Ask again once time travel has been invented and someone tries it out.

 

[ChubbyLiv]

Of course you did, the moment you kill your grandfather, you'll slowly die with him, slowly disappearing into nothingness. Because at the same time, you killed the possibility to be born.

That's if you're blood related. Who knows maybe your father was adopted. Yup, the future will change, but there's a possibility that you'll exist, somehow.

Depends on which theory about time travel you apply.
1. The paradox you mention
2. Multiverse - You killed your grandfather, which only created another parallel universe in which you never existed, but your original timeline is still intact.
3. The past is set and cannot be changed - no matter what you do, it won't change the past because it all already happened. Either you fail to kill your grandfather before he impregnates your grandmother, or the person you killed was not your biological grandfather.

 

[Sabruness]

Yeah, what Cupcake said. Either that or the universe implodes as soon as you kill him because the paradox breaks the system.

Multiverse theory. This is possible but we never know. Some people say Mnadela effect happens because other universe sometimes collide with other universe creating the illusion that something exist whereas there is no such thing. To be honest this quite interesting.

 

[Daichi]

There is one more scenario where this paradox exist. It goes like this, you are a upcoming writer but you don't know what to write. You have a time machine and you went to your future self and took a copy of book written by you which is successful. In the present you publish that book and become successful. Now the question is if you got the copy from future and simply copied it then who created it in the first place?

 

[Mihou]

Still yourself.

Nope. Your grandmother got her sperm from elsewhere.

 

[AliceShiki]

Time paradoxes are well... Paradoxes. They aren't supposed to make sense.

No need to give it too much thought.

 

[Assurbanipal_II]

I don't see the issue with this conclusion. Where is the paradox, Daichi?

 

[Kldran]

Someone made a video game with time travel. It's an RTS. In that game it is possible to send a unit back in time to destroy the building that created it before it was created. Due to the game using time waves to propagate changes, doing so causes the timeline to alternate between the one where the unit is made, and one where it isn't.
