If u went back in time and shot your grandfather before he had your father as a child what would happen?kbubba92

its not a dream its hypotheticalkbubba92

You would just disappear.TheHimura

nothing would happen, because you would kill him dissapear but then if you dissapear then you wouldn't be able to go back from the future to shoot him so you would come back...maybe.

Very interesting question. I believe that if you went back and shot your grandfather, you would still live on as the present is ever-moving, thus why you continue to exist. I've always been the one to subscribe to the idea that what you change in the past won't affect your present. The past would move along a different timeline, but yours would carry out as it always has.JustPlainLucas

Then you would never have gone back in time to shoot your grandfather because you wouldn't be born.Devouring_One

Or maybe your trying to kill your grandfather would end up with him getting laid. Awesome.

If you think about it, there has to be mutliple timelines.  How else can you explain being able to go back and shoot your grandfather?  If it was a constantly updated timeline, you would never have existed had you shot your grandfather, thus your grandfather would have never been shot.

If his grandfather dies before the father is born, then the time traveler cannot be born. But if the time traveler is never born, how can he have traveled back in time in the first place?

I like thinking about stuff like this, though.

You might create an alternate reality where you don't exist, you might end up being your own grandpa (*wink, wink*)...or you might just shoot the wrong guy...

Then you would never have gone back in time to shoot your grandfather because you wouldn't be born.Devouring_One

but then if u never were born u never couldve killed your grandfather 

Well seeing as time travel is impossible, no matter what tech level we are at, you would just be a man without a family.

Now we live in 10 dimensions, while only being aware of 3. The 4th Dimension is time, and thus can't be changed, no matter how hard you work, you can go back in time. You can however travel to another universe where things are slightly different from our own universe. You could shoot your grandfather, but nothing would happen to you, because you grandfather had you in the other universe.

So basically, if you went into the other Universe ( let's call it B ) and shot your grandfather, nothing would happen to you, because your original universe ( A ) is still effective, you just aren't currently in it.

So no matter what happens in B it fails to affect A.

Go here if you want to learn about our dimensions, it really does make sense: Link

It's impossible for that to happen because you would cease to exist after your grandfather died, meaning that you would never have existed in the first place, so you could never shoot your grandfather in the first place.

Time travel doesn't exist, BTW.

Well, let's suppose it was possible to travel back in time:

Since you are there, you'd already be in an alternate history to begin with.  You would actually be the product of a timeline that no longer exists except in your memory, except that in some sense it does have to exist or you couldn't have travelled back in time to begin with.  So while everything else has essentially moved backwards in time, you have not.  Basically the new "past" is not actually your past.  If it was, you would not be able to be in the past in the first place, because you would remember the past that you are actually helping to create, which is itself another paradox.  The new modified version is actually, from your perspective, the present and future.

If you shot your own grandfather, it would prevent a genetically identical person to yourself (presumably with the same name and similar personality, as long as you didn't directly interfere) from coming into existance.

And since paradoxes logically cannot happen, it would seemingly have to work that way (again, assuming "time travel" was actually possible).

I don't believe you can make a hypothetical about something that isn't even theoretically possible.  If it weren't possible with today's technology, but there was sound evidence to point as what could happen then you could extrapolate further, but as it is there is no reason to believe that what you just said could even possibly happen, so no one has a clue as to what would happen if it did. 

As for the single/multiple timelines, Theoretically there couldn't be only single timeline but time travel still be possible.  That would mean essentially that time is an illusion as everything would happen at once and it would be impossible for someone to not create a time paradox at one point or another, thus nullifying existence for all time.

Side note: You (TC) should probably look up the term "paradox". 

I guess you would cease to exits. But you would not be able to exist in the past so you would not be able to kill your grandfather which would cause you to stop living...but if you were to be able to send a message to the past (There is a machine that is said to send messages to any time which has the machine, so from now on we can send messages to the past as long as the machine exists in that time hyphotheticaly) you could tell someone to kill your grandfather..but since doing that would make you non-existent you would not be able to send the message......phew. If you go half way every time, you will never reach the end (This is actually true you will never reach something if you go half of what you did before everytime, 100 yard field, you go 50 yards, you go 25 yards, you go 12.5 you go half of that and so on) If you must "Love thy neighbor" and they try to actively kill you, if you are killed you can no longer love them, and if you restrain them, that is not considered loving them anymore.... my head hurtsTermite551

Do you want to shoot your Grandfather or something? Should we be alerting the care police?
