Time travel

[N1k23]

There is no proof that it is possible, but let's just say that time travel is possible and you had a time machine, these are a few things which my science teacher told me which drove me crazy, what would happen if you:

1. went back in time, lets say, a year ago and shoot your past self, would you just vanish into thin air?

2. went back in time about 6 months ago and prevented time machines ever being made, then technically you should not be back in time because a time machine was never invented.

3. You kill someone, go back in time, prevent yourself from killing them and bring them back to the future, have they been brought back to life?

biggest. brain teasers. ever

Lets just put it this way.. Time travel is a mystery that probably will never be solved.

The infinite quantum universe suggests you would create a new "parallel" universe by going back in time.

There are also theories that say you cannot defy causality and so the universe will always make sure you are not able to go backwards in time.

Etc etc, it's mearly a thought-experiment.

So either we can go back in time and we will be able to adjust things and end up in a different future universe, or you will NEVER be able to go back in time.

I very much doubt an infinite loop would occur, the universe has been too finely programmed for that

Yeah there's not all to talk about when you bring up paradox's, but what i want to know... if we can go back in time, would we advance our own race, is it future us (or aliens perhaps?) that built the pyramids? bought about computer technology so fast or invited the wheel? fire? taught apes to come from tree's and eat meat and use their thumbs?....

I think paradoxs will always resolve themselves... yeah that is an option 3 that I forgot to add with mine - if you go back to the future and do something, that action will resolve into a consequence seen today.

The Universe has it all sorted. It's like the perfect computer setup with no bugs, anything you do will not crash it - that's my firm belief. (BTW The computer thing is just an analogy, I'm not saying the universe is actually a computer simulation).

 

[Kitfox]

Depends on the way you look at it. I will talk theorys within movie talk.
First the John Titor way. This way mean that every time you go back in time you jump to a different dimension that is similar to your but is now different because of the change you made.

Second the Donnie Darko way/ back to the future way. Where changing time line creates a tangent universe which is different from the real universe and can be changed back by undoing that which you did.

Third is the Twelve Mokeys way. Where you can't change anything. You were ment to go back in time and the way everything plays out is the way it was ment to be. Meaning that no mater what choice you amke it was already predetermind.

Fourth the primer way. You go back in time and kill your self and nothing happens. Imaginate liek the world can't handle the concicounces and doesn't do anything. Time may change but you still alive. I'll explain this further in a second right now i have to go do soemthing

I don't believe the 2nd way could work, because whatever you do to try and undo the change, it will never work out exactly right to fix it.

But your movie analogies are good. :cheers:

If I could time travel, I'd pull a Dane Cook and go back in time and spank my dad on the ass when him and my mom were having sex to have me.

*SPANK*
"I'm your son from the future!"

I think first. to attempt to answer any of the questions, you have to somehow fully comprehend what time is, something we still truely dont understand, I believe perception of time is purely in the concious mind and we are as much a part of the puzzle as universe around us.

A question for the philosophers?

1. went back in time, lets say, a year ago and shoot your past self, would you just vanish into thin air?

I reckons you can't change anything at all, ever. Twelve monkey way.

Let's say you go back in time to kill Hitler.

You reason that the easiest way will not be to devise an entirely new plot, but to make sure a failed one doesn't fail.

Thus, you decide to make sure the Nuremburg plot actually works.

You are caught by the nazis and killed and dumped in a river.

biggest. brain teasers. ever

1. Impossable, if you killed yourself in the past, you wouldnt of been able to go and kill yourself in the past.

2. Same as above.

3. This just doesnt make sence. If you go into the past to kill someone, then go again to stop them. The first time you go your "future" self will allready be there stoping you. It would be impossable to kill them. Taking them into the future wouldnt do anything since from that point on they would be in the future.. nothing odd there.

Get better brain teasers then this.

Of course if you go with what some people say, that if you make somthing like that happning (killing past self) a new universe line will split off from that one.

edit: I love the "Tangent universe" used in Donne Darko, as its different then alot of other things around if.. If you go the main DD site and do some of the puzzle there, you get to read the Time travel book, its interesting.

1. exactly, what would happen if you did do it?

2. same as above

3. what I meant was, if i killed my friend in the present time and went to the past 10 minutes before I decided to kill them and brought them to the present, what would happen?

Impossible. If you brought them to the present, they wouldn't have been there to kill.

Of course Ritz, this is where i ask you to prove what you've just said is true.

 

[Burn]

Of course Ritz, this is where i ask you to prove what you've just said is true.

I didnt say it was true at all, but for any of those to happan it would defy logic, only way it could happan is if it made a tangent universe (And in that case nothing would of changed after the unvirse is fixed) or alternate universes, and if thats the case, its perfectly logical.. in a way.

Pretty plain no one can prove anything when talking on time travel.

 

[N1k23]

yeah, thats true, 1/3 solved

Yes I do.

YOU GOT BURNED!

1. See my last post
2. Same as above
3. Sorry I didnt understand what you ment, in that case.. Same as above.

Time travel is such a fantastic topic to talk about, so interesting.

I would presume that parallel universes would be the answer as there are already a number of theories pointing towards their existance.

 

[Sulkdodds]

You go back in time to stop the Hiroshima bombings.

You stow away in the cargo hold of the Enola Gaye. (plane that dropped the nuke).

Unfortunately, the bomb bay doors are opened and you fall out, along with the nuke.

History runs its course.

Even if you kill the pilots and take the nuke with you and hide it, I guess America would just make another one to drop.

But if you travel back to the future and find out that a bomb was still dropped, couldn't you then travel back in time and then stop the new a-bomb from dropping? Couldn't you keep doing this until America just gives up trying to nuke Japan?

 

[Sulkdodds]

Ah, but I think you'd A. Always fail and B. Probably die in at least one of the attempts to stop the bomb.

For example, you kill the pilots, but can't fly a plane, so you crash into Hiroshima.

Or one of the pilots, with his last breath, hits the 'blow it all up' button.

Or you hit a bit of turbulence, making the plane shake. You trip over and bash your head on the 'drop bomb' button, knocking yourself out so the plane crashes AND dropping the bomb.

Okay, I find it a slightly humerous theory. The idea is, no matter what happened, SOMEHOW everything would work out the same.

The point is that the nuke has already been dropped. So anyone who went back in time to stop it obviously failed.

Just hold on tight and ride the bomb to inevitability.

Well since we don't know anything about time travel thats a pretty impossible question....
:O spammage!

According to Sulkdodds' Twelve Monkey-type theory, if he went back in time to try and fix it, he would still have failed at the :imu:!

The Multiverse theory, if an action that you do in the past has a reaction then you would branch off into another universal possibility.

For example,

You went in time and killed yourself, then You yourself will still be alive, but you would b in the wrong universe. Watching Back to the Future 2 will help you understand the possibiblities of alternative universes

It's true. The evidence is right there in his post!

 

[SimonomiS]

Do you mean the actual action wouldn't change, or the eventual outcome? I mean, if you tried to kill Hitler as a baby, would you either fail at killing him, or would there be a dictator as bad as him regardless?

Lookit me cuuuuute avatar! If only it was spinning...*hint hint*

 

[Foxtrot]

If you have sex with yourself from the past is it considered masturbation?

 

[Steve]

Do you mean the actual action wouldn't change, or the eventual outcome? I mean, if you tried to kill Hitler as a baby, would you either fail at killing him, or would there be a dictator as bad as him regardless?

Unless you go with the multiverse theory, you would fail at killing him entirely.

I think he's trying to say that because Hitler has already come into power in OUR time, it obviously means that if someone had gone back in time to kill hitler, they failed, because the evidence that hitler came to power still exists.

Though really that can also mean that someone worse than hitler had came to power, and someone went back in time and succesfully killed this trueley evil dude, but when they arrived back at present time, Hitler, who was still evil, had come to power.
We don't know when the timeline has been changed, because we're all interwoven with it. You can only be aware that something has been altered if you aren't a part of Earths time line, or a glitch happened and people are suddenly talking about Hitler when you believe no one called Hitler ever came to power during the 1930's.

 

[SimonomiS]

In effect, making him invincible? Until his predetermined death of course.
