okay look now i've got another one. of you go to the future, and if you happen to need something, let's say a hammer, and at that moment you decide, that you'll go back to the past, place a hammer at a location and return to the future........now my question is, would the hammer be there at the moment you decide to put it there, becuse from that timeline's stand point you have already travelled to the past and put it there. No this wouldn't work becuase in your current timeline you would have to have had to hammer; you put it (and your self) in a differnt time line as for Cario's destroying your self you wouldn't have been born in the new time line but your would still be stuck in it and you would still exist because you were born in the old one and crossed over |

Those of you in favor of the existence of time travel are all using parallel dimensions to explain away what's known as the "grandfather paradox." I will quote it even though you're probably aware already If a man were to go back in time and kill his grandfather as a child, logically speaking he would not be born, since his father before him would not be born. But if he wasn't born, he can't go back and kill his grandfather, therefore his grandfather lives, and the grandson is eventually born, therefore he can kill his grandfather, and so on... So you say that you're not exactly going back in time and killing your grandfather; he's just a parallel grandfather. However, many people don't believe parallel universes exist at all. For example, I'm sure you're all familiar with Murphy's Law. The one that states that "anything that can go wrong, will go wrong." Well the law really means that anything which is possible must happen, otherwise it was not possible to happen. This is in direct contradiction with the parallel universe theory in that parallel universes are supposed to branch off every time a decision is made. Every time a ball can roll in 2 directions, the ball will roll one way in universe A and the other way in universe B. Still, this completely ignores the fact that the real reason the ball rolls a certain way is the shape of the ground. The ground does not change, therefore the ball can not mysteriously roll a different way. Everything in the universe is causational. So if you're going to argue that time travel is possible, you better try to come up with a more inventive explanation than just saying "well you go to a different universe." That is just too simple and it ignores basic facts about reality. |

i agree, if you change something in the past, something that does not affect you in the future(for ex. wipe out australia  ) the timeline is changed, but that would also mean, that you cannot remember your actions in the past, since they become a part of your life in the future(except stuff that doesn't have any, even primorial connection to you) |

That is just too simple and it ignores basic facts about reality. accually it would not work that way because in your model the ball can't roll way B (also in your model there would be infinately many universes in which it would go either way)a better model would be the classic cat in a box system (explained below for those of you who don't spend your entire life reading science articles) There are two therories one states that If a cat was placed in a bow with a pill of posion that will either activate or not based off of a radioactive decay then the cat will neither be dead or alive untill one observes it the cat will be in a state of quantum flux; this is Hiesenburg's theroy; The other theroy states that there will be infinatly many universe branching off of that point in infinatly many the cat lives and in infinatly many the cat dies; this is Feynman's theroy And then there is Murphy law: the cat will eat the pill  |

WRONG! what happens if you toss a coin? both heads and tails is possible but they do not both happen? |

I find talk of the universe kinda interesting but mind numbingly difficult to grasp. I do think it's possible for an infinate number of parallel universes exist, each one differant from another by a single change, and some completely differant from the others. We can't prove if it's true or not, so I just sit back and let the universe unfold as it sees fit.

both heads and tails is possible but they do not both happen? well both aren't possible, since it's determined which side the coin will fall on when you flip it, the actual flip, the wind speed, the intercepting floor or hand, when it falls, and so on, only one alternative is possible, others cannot happen, this holds true for everything, everything is determined at the time of action, if you could travell back in time and watch that coin fall and fall for infinite amounts of time it would always fall the same way, and land the same way. |
