I Have Solved the Grandfather Paradox

hi all
i have answer against you
if i killed my grandfather i do not exist but what is going on if i kill your grandfathers?????
i can travel to past ,i exist now ,also u are,insist of my grandfathers i will kill another man so is there son or daughter exist here????it is the answer 4 all that say if i killed my grandp so i do not here ????????

if i had more time i would explain thi sto you but i will be back to do so. you all have the idea of time wrong

Ha!!! the grandfather paradox!! well, why your grandfather, and not your father? and i think killing is a little extreme, all that you would have to do is alter reality a little so that you are not concieved, the death of your grandfather isn’t the only or best way to do this. anyway, no one has built a time machine or developed any other way of time travel that i know of so the point is mute. but it’s fun to discuss. really i think the best way to accomplish the goal of never being born is to alter another persons history so that they in fact become the ones who interfere in your conception. that way, you don’t have to be directly involved in your non-birth.

There is no possible way to travel back in time. If one were to have a reason to travel back into time, such as to murder Hitler before the Holocaust, then if one were to fix the problem or reason they had to go back in time, there would have been no reason to go back in time in the first place. This causing the person with the reason to travel back in time to have no reason to travel back in time in the first place, so then they would not have built the time machine to go back in time and thus did not go back in time so the whole thing would start all over.

Even if it were possible: a man traveled back in time and killed his biological grandfather before the latter met the traveller’s grandmother. As a result, one of the traveller’s parents (and by extension, the traveller himself) would never have been conceived. This would imply that he could not have travelled back in time after all, which in turn implies the grandfather would still be alive, and the traveller would have been conceived, allowing him to travel back in time and kill his grandfather. Thus each possibility seems to imply its own negation, a type of logical paradox.

See the Novikov self-consistency principle and Kip S. Thorne for one view on how backwards time travel could be possible without a danger of paradoxes. According to this hypothesis, the only possible timelines are those which are entirely self-consistent, so that anything a time traveler does in the past must have been part of history all along, and the time traveler can never do anything to prevent the trip back in time from being made since this would represent an inconsistency. In laymen’s terms, this is often called destiny.

Hi All. I have studied the GP (Grandfather Paradox) for years and the whole point of this paradox theory is the following:

1. Let’s suppose the grandfather builds a house when he is 20 years old. I enherit the house long after he is dead, but travel back in time to kill my grandfather at the age of 19. When I return to my “contemporary” time will my inherited house physically exist or not ?

2. I have a printed photograph on photographic paper, in my photo album, of my grandfather, father and myself, that is 3 generations. If i then decide to travel back in time and kill my grandfather at the age of 2 years old, would this mean that my photograph is not physically in my photo album ? and if it is will the image of all 3 generations be there, even if the photograph has been made before the people who are on it have ceased to exist ???

We need to look alot further further into this paradox !

does not dose

try this one for size

what if you hired some one else to go back in time to kill your grandfather.

you wouldnt exist and since you don’t exist, that means you never hired that guy to kill your grandfather.

You can’t solve a paradox, that’s why it’s a paradox.

You can show why it isn’t a paradox after all though.

Actually, if you accept the theory of alternate time lines, you wouldn’t disappear. An example, perhaps.

Let’s say that Point A leads to Point B. Then, let’s say you create a Time Machine at Point C. You use the Time machine to travel back in time to Point B. At Point B, you kill your grandfather. You then create an alternate time line. At Point C, you would still be alive because that is the “future” in which you DIDN’T kill your grandfather. However, at Point D (new point that you just created by killing your grandfather), you wouldn’t be born. However, you would still be there. Nobody would know who you are, but you would be there. This defeats most of the purposes that we have for going back in time. Why go back in time to stop your ______ from dying when it wouldn’t change line ABC. Btw, I’m not sure if this is right, after all, i’m only 15...

If any of this is incorrect, I’d be glad to have a conversation about it.

........................no.

I thought the movie Back to the Future answered all these question and solved this riddle.

why would anyone want to kill their father or grandfather?

In the name of Science.

Accually there is a way to travel back in time. If you were to enter a wormhole as it passes through a solar flare then you travel through time. Also if you could travel past the speed of light in either direction then you can travel through time. In a way astronauts are time travelers cause they travel 25,000 k/m an hour when they are in space thus slowing down there age progrestion. the faster you travel for long spans of time the slower you age.

This is the quote i ment to respond to not the other. Sorry about that.

But if you kill your grandfather, you wouldn’t be born, if you’re not born, how the heck do you kill your grandfather?

Hope no offence is taken.

Time is a not a 1 way but a 2 way. You can travel back and forth.

So the question is what happens if you killed your grandfather back in time. Of course you would cease to exist, but put it to this way. If you traveled back in time and killed your grandfather, how can you travel back if your already dead?

there is 2 way

1. Everytime a single change happens in the time stream, a parallel Universe is created without interfering with the original universe. This is plausible because scientist says that there are infinite universes. So that means you can change time as much as you want.

2. This one is kinda tricky. Lets say you killed your self back in time. That means your were already dead. So THAT IS IT! Your already dead, you dont even exist. This is also plausible because there can be an infinite chances of other people being born. Which in turn there are infinite way of not to exist.
