Time Travel

[The Ninja]

suppose you go back in time and kill yourself. what would happen? and what would happen if you went into the future and killed yourself.

p.s. please dont say anything like time travel is impossible. this is all theoretical

[Shadowhunter]

well if I went back in time and killed myself technically I would be my future form killing a past version so I would cease to exist from that point on the moment i killed my past self both of us would no longer exist because if my past is gone then there can be no future me. If I went to the future and killed myself it would not change my present timeline but would change my future. When I return to my present time line I will live until the point in time I time traveled to kill myself and would meet the same fate as my future self by my past self.

and it still is technically theoretical but an IT dude came to my school in like jan or something like that and said that the way humans are progressing time travel is an actual possibility but the whole travel to the past cant happen you can only travel forward in time not backward.

[Iron Man]

Not necessarily. If you killed yourself in the future and went back into the present, you could take steps to insure you didn`t repeat the performance that led up to your death by yourself. If I went back in time to kill myself, I would have erased myself from existence, but, If I didn`t exist, I couldn`t have killed myself. Thus, I would be unharmed. It works just like the Grandfather Paradox, if you have heard of it.

yeah i was hoping someone would say that

[Shadowhunter]

ah youre right I never thought of that hm..I love the idea of time travel (: still though we cant travel backwards which is a disappointment....never heard of the grandfather paradox but I will stay now topic now haha

isnt that still just in theory since it hasnt been proven

[Iron Man]

Only proven if time travel is discovered, used, and so on and so forth.

i was just thinking though what if you killed your future self went back to your present self after you killed your future self and induced amnesia of the event. now if you did this would you forget to give your self amnesia and be uneffected or would you just forget you gave yourself amnesia. my brain freaking hurts ima gonna get some sleep.

[HillBillyWilly]

Yay Paradoxes!


If i went back in time to kill myself, then i would be already dead and unable to go back in time therfore my preesent self would cease to exsist because my future self had killed my past self, erasing my exsistence. Therefore, i would never exsist because it would be immposible to live after beign killed :D

[Shadowhunter]

no physics explains one cannot travel backwards. Many scientists today are proving it that it is not possible to go backwards but there are also others who say it is but....i read in an article that in math one can move backward and forwards in the 3 spatial dimensions but time does not share this ability to have freedom of movement because it is in this four dimensional space time in which you can only move forward therefore time travel to the past is not possible even if we could time travel at some point in our lives

You would still change the course of events. When you went forward in time, your future self that you kill didn`t have amnesia. But when you went back to the present and induced amnesia, you logically changed things where you wouldn`t be killed by yourself, because you would be doing different actions than your non-amnesia counterpart.

so would i be able to kill myself or not. i dont completely understand will you plz dumb it down for me. :D

[Insanity Fair]

If you went to the future it would be damn hard to kill yourself because you would know that you were coming.

[Iron Man]

Oh wait, only 1 copy of you would exist if you went into the future. It would be like you just disappeared into thin air at the point of time travel. Damn it! How didn`t I think of that?

this literally made me lol

[ThereforeIam042]

Just food for thought,but time and (I'll call it sequence since I believe I've forgotten the correct term)are to entirely different things,here is an example,a b and c are points in time and demonstrate sequence, since the points a b and c occur In that order we assume that a causes all following points,However since a b and c are all different points,if you were to remove a, b and c would continue to exist since they are seperate points time,if your really interested checkout orson Scott cards book pastwatch

[Jess]

if I killed my past self i wouldn't exist...and if I killed my future self....well I wouldn't exist in the future I guess

[Magus]

Ever heard of time slips?

Yes, it is a true phenomenon, but it isn't scientifically proven.

That is so photoshopped.

[darkwoon]

suppose you go back in time and kill yourself. what would happen? and what would happen if you went into the future and killed yourself.

p.s. please dont say anything like time travel is impossible. this is all theoretical

I believe that, in such a case, I would jump from one probable universe to another probable universe - in short, timetravel would be synonymous of travelling into the multiverse.

If I go back in time, then I arrive in an universe in which two copies of myself exist: the one of that time, and me, the time traveller. This is obviously not the universe I came from, since in that one, only a single copy of myself existed at the time I'm visiting. Hence, the jump backward in time was effectively a jump in another, parallel, universe.

What I then do in that parallel universe doesn't matter at all for my own existence, then: I can kill my alter ego of that past, or change his life, it will only change the outcome of the universe I'm visiting, not the outcome of my universe of origin. Hence, I wouldn't cease to exist, and no paradox happen.

In fact, I'd actually never be able to get back to my original universe - a bit like the second principle of thermodynamics, all my travels in time could only add interferences from my part, and never remove any. Hence getting back to square one is pretty much impossible.

Now, that's just an hypothesis...

[MisterE]

i posted to this then read the rest of the question, my bad :P
i dont really know what to think, i think of things to scientificly :P

[Continuum]

Hopefully in the near future, we can cause anything from extincting ourselves to extincting the dinosaurs. That way, there'd be a logical explanation why they died

[maestro15]

Other than paradoxes, IF you do kill yourself, I believe that you kill yourself in another universe that was previously made. Im confused now

[Skeln]

If you were to time travel (that's a big if) and kill yourself in the past that I think the whole idea of parallel universes would protect your current self. If you killed your future self, well you can prevent that seeing as how you know what to expect.

[Continuum]

If we time travel and kill our past selves, they die, and also our present selves will. But, if our present selves didn't die, then no one will kill our past selves, so we're safe. If we're safe, then there will be someone to kill our past selves, then undeniably kill our past selves. But then no one will kill our past selves so we're fine. If we try to undo the killing before letting your past self die by killing your other present self then that would mean you're dead.

[Death]

Real-life paradoxes like this would never happen because as far as I'm concerned, the conditions which would be required can never happen.

[Dive to Survive]

If you traveled through time and killed yourself in the past then you would also kill your present self so you would be no more...I think. It's a confusing matter.

[Death]

^^But your lack of existance would mean that you would never have been able to kill yourself in the past in the first place, meaning you'd still be alive. It's an illogical loop, and thus a paradox. It's things like that which show how time travel is a far-fetched notion.

No, it just shows how limited human reasoning is when it comes to the fourth dimension. We're so used to thinking that time moves only one direction that to think otherwise is exceedingly difficult.

[Death]

So what do you suppose will happen if we killed out past self, or mother, or someone responsible for your existance, etc?

[Sith Lord 13]

My theory?

Split timelines. Since you're in the past you're unaffected by the temporal change. You return to the the future, you'll find out no one knows you, because you've never existed.

[Death]

So you can exist despite what causing your existance being non-existant? That's like something coming out of nothing.

[Perseus]

Instead of traveling in time, it'd make more sense to be traveling through universes, and you're affecting that place because time travel makes no sense because of the paradoxes. This is a comment on y'alls' conversation, by the way.

[Death]

Traveling through universes? If this were true, exactly how many universes would there have to be? And even then, how would you go about time travelling?

[Deathwingo0o]

Time travel can only be achieved when you travel at a speed
faster than light itself, to the future.

[Death]

I've heard that analogy before. I've also heard that there will never be a way to travel at FTL speeds - unless we've figured that out too...

[Insanity Fair]

If you went too far back in time, the minutest details could change history. A flash of lights in the 1800's could change blood lines, prevent invention, and maybe even create a whole new religion. If a time machine that could take you back in time were ever to be invented the general public would not hear of it.

[Perseus]

I've heard that analogy before. I've also heard that there will never be a way to travel at FTL speeds - unless we've figured that out too...

FTL speed is impossible, as is light speed. Light speed is impossible because as you start to travel faster, your mass increases. To achieve light speed, your would need an infinite amount of mass.

[Death]

^^That's what I thought. So how would one go about traveling in time? Because it seems impossible to me.

[Sith Lord 13]

Ask an 18th century person and they'd tell you flight is impossible. With our current understanding of the rules of the universe, we do not see how it would be done. But it is not impossible.

[Death]

Tell you what, if time travel ever becomes possible and I do it myself, I will denounce my atheism and accept Jesus Christ as my lord and saviour.

Besides, do you think we'll figure out how to move objects at will (telekinesis)?

Oh I doubt it'll happen in out lifetimes. I just think it is physically possible.

Yes, I do believe telekinesis is possible. In fact, we have monkeys doing it now. They've been implanted with a device which reads their brainwaves and allows them to move a robot arm across the room. With infinite time and infinite materials, I believe almost anything is possible.

[huginnmuninn]

if you went in the future to kill your future self then your future self would know that you were coming to kill him so he could probably stay alive or he could let the you kill him

You know if time travel existed today the first stop should be to the time of Jesus to question him face-to-face.

Traveling at the speed of light is impossible. The only way around this barrier are worm holes, which I'm pretty sure you know what they are.

[Sith Lord 13]

The only way we know now. I'm of the opinion that science can, with enough time and resources, find the solution to almost anything.
