Timelines are very fragile All you would have to do is have a butterfly flap its wings in the amazon for a completely altered chain of events to possibly occur. (The Butterfly Effect). This is possible if for instance that flap of wings scares a predator which ends up not eating that butterfly starving to death and then not being able to etc.. etc.Which would have caused for instance you never being born.

While the butterfly effect is made to make a point, its true any slight alteration of a timeline can have drastic effects on the rest of reality. For instance, you travelled back in time and accidently knocked into your grandfather while he was in college right when he was going to ask out your would be grandmother now he thinks that he is too embarrassed to ask her out because he tripped and fell completely and your grandmother will always ridicule and remember that.It doesn't even have to be that farfetched for example car accidents happen daily you could have a car accident that your past self never had when travelling backwards in time and this would result in the death of your grandfather. There are all sorts of different theories on how time travel might even work in reality for instance if you watch back to the future, a movie I would recommend.

You might notice that he carries photograph of him from the future and as he inadvertantly alters timelines affecting how his grand/parents met, the photographs begin to fade to solve the paradox in time caused by the fact that his grandparents never had children which could never have children which could never have children. And what is worse the further you go back in time the lest awareness you might have about how each action might affect time. You might go back to the time of king arthur and accidently lead to the hanging of your would be ancestors.

The real paradox comes in where, does this actually happen? On one hand, you eliminated your family this means you were never born so you should cease to exist. But on the other hand if you were never born then how could you have altered time to make it become in this state of your non-existence.

Time travel backwards becomes infinitely complex with such a paradox as the grandfather's paradox.

Very interesting stuff Back to the future explores all sorts of paradoxes such as if you meet or touch your former self+ the grandfather paradox.

The butterfly effect demonstrates how one event can lead to all sorts of changes/ripples in timeline. Donnie Darko more time travel exploration amazing movie .

The paradox is that if I could travel backwards in time, I could (theoretically) meet my grandfather. Now, he died before I was born, but if I were to get him when he married in 1910 and kill him before my dad was conceived, then I just killed the one responsible for bringing me into existence. If he doesn't exist, I don't exist .. .

But I'm standing there, gun in hand, existing. That's the paradox. Do I evaporate like in Back to the Future?(As Marty and his siblings began to disappear from the photograph) Or do I continue in another timeline?

And yes, the confusion really gets going when we propose other timelines (as was done in the second Back to the Future movie. ) So, simplified paradox: if I kill my grandfather, do I still exist? This was done hilariously in Futurama where Fry indirectly kills his ancestor (sends him into the Trinity atomic bomb test) and has to take his place, and does, impregnating his own ancestor to end up creating himself.

Or does he? Danielpauldavis's Recommendations Futurama: The Complete Collection Amazon List Price: $199.98 Used from: $128.95 Average Customer Rating: 4.5 out of 5 (based on 39 reviews) While you're laughing, I believe you'll end up understanding that and other concepts of physics. Good stuff..

Lotsa problems. Lotsa problems with time travel: (1) "If you went back in time", whatever the heck that means, and did something so your grandparents never met, then..... (A) You would dissapear, as your whole family tree would never happen. (B) You would instantly be "somebody else", maybe still the grandson of your grandfather?(C) You would still be yourself, after all, you already exist.(D) Something would prevent you from preventing them from meeting.(E) Whatever you would do, it would be the cause of their meeting.... it all depends on how you decide the past is: is it done with and unchangeable, or if you change it, does that invalidate the "present", or does it spin off an alternate time-line.(2) If you went back in time, and married your grandmother before she met gramps, then you'd become your own grandpa.

Go rent "Back to the Future" and it's sequels and study those real good. Also a few Star Trek TOS episodes dealt with this..

Before quantum mechanics... The Grandfather paradox was a way in logic to explain why travel back in time was not possible. Why? Because, the present is reality; it is...what it is, so to speak.

If we could go back in time we could change the present which ...is what it is. You are here and planing to travel back in time. So, you travel back, go to a bar, meet an offensive drunk, get into a fight with, WOW, your grandfather, belt him a good one and he falls on the edge of a table, cracks his head open and dies.In this case, you would never have been born and the incident would not have been possible.

It simply could not have happened because, as you can plainly see, in your mirror, you do exist! Sources: rednecksputter, fill-oss-a-fur, inadequate education, read some, been places..

1 Easy! If you time traveled into the past: Accidently killed your grandfather or changed whom he married...you would never be born...The paradox!Blessings.......Annlee .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
