Exactly, the paradox of time, i tell people stuff like this all the time. Also, LOL for "Sorry gramps this is for science" However, if you are a true believer in fate in that everything will happen the same way, you'll still be created just with a different grandfather, GrandpaX however, you might just go back in time and kill GrandpaX and would therefore have the original grandfather?
As Hockey said, there can be many different things that could happen. When you kill your grandfather it will rewrite time, and you will have another grandfather. It will rewrite time. Much like how Fry became his own Grandfather. Since.. if time is already written.. then history already had you going back and killing your ' grandfather ', so he wasen't your grandfather to begin with.
Good explanation. I believe, though, that in reality, by traveling in time you place yourself on an independent timeline, and thus when you murder your grandfather, while you cease to be born on your original timeline, there is no reason why your particles should cease to exist on your independent time-traveling timeline. You get it?
Thats why if you did go back it time, many believe no matter what you do it is what is meant to happen. I remember a an episode of some show, I can't remember the name, but the plot is, some guy goes back in time and kills the baby hitler, but the nanny for the hitler household is afraid she will be blamed and buys a homeless baby from the street and that baby turns out to be the real hitler.
entertaining, but if you can trtavel back in time, you can kill your grandfather. You'll still exist, because time isn't a tangible thing, it's just the space between observed events. You exist, you'll exist when you kill your grandfather, and when you return to the (alternate) future, you'll continue to exist...you'll have just never been born in that reality.
You create a different timeline. An alternate dimension, identical to the first until the time of your interference. Grandpa will be killed my an unknown assailant, as you and everything you brought with you will disappear. In the other timeline, you never return home. In yet another, you never go in the first place. And also, you grow a goatee.
Funny, but nothing new. Einstein knew this too. Thing is that you won't neccessarily be born or go back in time again the second time, so basically you'd just have never existed. Still, clever loop. Einstein also said tiem travel forward is possible but really you may as well freeze yourself then. String theory works so much better for this...
Yes, but your time machine can go forward in time. So after you kill your grandfather, you would be able to go back, but it would be to a world in which you never existed, and are a stranger. You would live in this world for the rest of your life. Now, if you DIDN'T kill your grandfather, and you went forward in time to right before you left, and prevented yourself from going back in time, you'd have a new twin.
The multiple worlds theory, if correct, disproves the grandfather paradox. See, by going into the past, a new timeline is generated since you are out of place from your natural place. Any changes you make are actually affecting a different timeline, not your own timeline of origin. Time travel and the theories behind it are more complicated than people make it out to be.
===so adino...youre 2ing the site because of the humor that shows Picard and
Lohan having a kid? It's showing one of the many paradoxes scientists face
themselves with all the time keeping many things theoretical===
No Actually I gave it a 2 because I thought it wasn't very good. The comment stuff was just a drunken rant.
If you travel back in time and kill your grandfather, you will still exist but won't be born.
Freaky, eh? You see, time is considered a dimension, like space. Think of a ruler and a block. The block starts off at the 12' mark. You then move the block backwards to the 4' mark. Does the block cease to exist since it is no longer at the 12' mark? No. Time will be different, but it's not required that something will happen to have happened after time is rewritten.
There are 2 ways this could go. Either the universe goes into a constant cycle of calculating how to continue with time(Much like this looped YTMND) or it creates 2 alternate dimensions, one where your grandfather died and you never exist except as your grandfathers killer, and the other where you do exist but your time machine fails to work so you can't go back. I've thought about this ever since I heard of the idea of a timemachine
well certaintly you know this is false because a paradox can not exist. So if you did go back in time you would go back into an alternate reality where u exist in the past. If you kill your grandfather there, he will still be fine in your reality, but dead in one... You just hafta go with the theory that there are infinite different realities. Plus killin your gramps is an awful thing to do =(
This is assuming that: (a) There is only one timeline and it is naturally 1-dimensional (b) Each cause-and-effect is serial and interdependent - there is no "predestiny" or "eventuality" for events (c) The "butterfly effect" is not just a thought-experiment, but a reality, in that miniscule events can have drastic consequences... But of course (a) There MUST be something outside the 1D timeline in order to timetravel, so parallel potential universes are implied (b) Not many events actually CAUSE other events - they contribute to them, certainly, but it's almost never a single circumstance influencing the event, and (c) Butterflies don't cause hurricanes - weather conditions do. Damn, this is good weed.
