-----------------------
A man travels back in time, he goess to see his Grandma when she was a child.He then kills her.This means that he can't have existed so who killed the Grandma? ----------------------- Depends on what theory you go by. I can't remember the name but I know one theory that would render this possible: there is more than one you existing at all times, pretty much one for each milli-second of your entire life, and each in a different realm of time. If you went back in time to kill a person, they would only be dead in that single time realm and would continue to live on in the all the others. So technically when you went back to the present she wouldn't have been killed. You could go into the past a thousand times and change a million things, but when you return nothing would have been changed because time is supposedly "separated" according to that theory. Does that make any sense? |

Welcome Elyam! Checked out the Newbies thread?
I think that makes sense. Do you mean in one parllel universe (There are supposed to me 11) because I think it involved with that after reading Universe in a Nutshell. My head is still hurting from that book! Oh I get you now! Yeah, sounds about right! |

No! Not Schrodinger's cat! I once spend a whole easter holiday trying to figure it out. I didn't really get it. I believe it's a metaphysical problem or something.
I've read it a little differently though. You take a box where you can't see through, inside you put a cat and a bottle of poison. When the box is closed you can't know whether the bottle broke or not. So you don't know whether the cat is alive or dead until you open the box. So technically the cat is both alive and dead at the same time until you check. I believe it meant to explain something about electrons. That you can either measure the speed or the position of an electron but never both at the same time. But I'm not sure, it's very probably that I'm mixing things here. I always like Pratchett's take on Schrodinger's cat with Greebo. Quote:

Let's split the first "paradox" into individual premises.[list=1][*]A man travels back in time[*]he goes to see his Grandma when she was a child.[*]He then kills her.[/list=1]To me, it seems that 3 is impossible, because if it did actually happen then 1 could not have happened. He might have gone back in time and saw Grandma when she was a child, but something must have happened to stop him from killing her. If the first two premises are accepted, then the third cannot be accepted.
I dont think it's an "unsolvable riddle", just illogical. Quote:

The fact that there was a safety net at the fourth floor is of no consequence to the correctness of "attempted suicide" because it is clear that the man is trying to kill himself in the second sentence. He merely did not know about the net. The bottom line is that the father should be put away for manslaughter. Last edited by Andúril : 01-19-2003 at 09:01 AM. |

Sliding Doors? I saw that movie. It was kinda confusing, but I liked it.
Someone already said this but here goes. 1)Person goes back in time 2)Sees his granny 3)Kills her It doesn't work, because 1 can't have happened if 3 happens. Therefore, 1 and 2 happened, and either this person kills granny, but in a parellel universe where things are different because Granny died, or it is impossible. These riddles are making my head spin. But I'm addicted, so I must keep reading and lay awake at night thinking of them....

Maybe he's adopted
maybe he was an adopted child. So then if he kills the family that adopted him grandmother then his blood grandmother is still alive!

I don't know about that. I think it shows that going at time T2 back to time T1 and killing your direct ancestors is impossible. Oh well...
