Time travel will never be possible.

[coldfrog]

Aside from accelerated forward travel which we can and have done, an interesting book to read about this would be "Time: A Traveller's Guide" by Clifford Pickover. One of the most fascinating stories with a very layman-like description of time travel possibilities that nevertheless gets quite serious with its concepts. Aside from going deep into the nature of light and time he also tells an odd story.

Time is instantaneous. Anything you try to change has already been done by you, so you're not actually changing anything. The past cannot be changed.

NON BELIEVER! :O

jkay man. i do see your point, but referring to my earlier point, you wouldn't know, as the changes may have already occured, and with you living in this timeline, you would continue believing this to be unaltered destiny.

Example: (This will make me sound super retarded i know) JFK. We all know he was assassinated. This change has occured, and we continue living our lives, with LBJ being elected, and us assuming it was "fated" and unaltered, just part of this timeline. However, this could be an altered past, where JFK was not assassinated. however, we would have no clue, as the changes have already occured in the past, altering our perception of the present.


RANT OVER.

kick the dipshit if you want to now, but i cite the 1st amendment

Hell, i'm not even American

Oh it will be possible at one point, and than someone will use it to fuck up the space-time continuim.

I will cite Samurai Jack...
Aku you dirty bastard...


But seriously? Going back in time would create a new universe, so it wouldn't matter anyway.
Catch my drift?

So what happens to the time traveler? He just disappears from the face of our universe? And what happens to US when our space-time continuum is fucked?

The time traveler will be possibly stuck on the new space-time continiuum, while us live our lives perfectly fine in the time traveler original space-time continiuum.

It's not that hard to get.

So you're saying that if someone went back in time that it would have absolutely no repurcussions on our universe?

Errr you wouldnt know it. If someone HAD gone back it time, we'd have no clue, because that would be the established timeline, there would be no way to differentiate between the two. This could have happened an infinite amount of times, we could be stuck in a 3000 year loop that just keeps going over and over. Refer to a star gate episode and a movie with guy pearce. Anyway, as someone mentioned earlier, this all depends on what theory of time and existence you subscribe to. There are a few floating around, linear straightforward ones (the most common used in this sort of debate) or multiple timelines parallel timelines etc. Its a great topic to talk about, very interesting. But to go back to the original question. I highly highly doubt itll ever be possible (i dont like saying anything is impossible)not because of paradoxes, those can often be turned around with another theory, but because think about it, how in the FUCK would you achieve placing yourself in a previous space of time. it boggles the mind to think that it COULD be possible, you're talking about...gah i cant even go on, ive mindfucked myself now. great. GREAT. thanks. lol

 

[solidd]

oh and also, i also have a sneaking feeling that somewhere someone or some government IS messing with time. I get "deja vu"s a lot, but its BS its not a split second lapse in reaction time, fuck that. im talking ive done this completely unique thing that ive never done in this exact way, only i did it two weeks ago IN MY SLEEP. or maybe im just special..whats that word..but yeah, when it happens, i sit there for a minute going wtf just happened.............a good example, I was sitting in a cafe in france, id never been to france before until then, my passport says so, and i was drinking a coffee with a person id met that day, i was newish to the language and i predicted the persons next sentence and had this weird flash or feeling id done it already. i said it in fluent french, some words id never used before aswell. it was fucked. the dude was like...yeah..exactly *gives weird look* anyway a split second reaction theory might apply to a door opening deja vu but not a whole freakin sentence in a language i barely spoke to a person id met that day in a country id never been to before. weird? or fucked up?

 

[Iron Sea]

There will never be time travel because time is here and now. You can't go back in time, because it already happened. There's no time 'line' more like a time 'dot'. It's already happened and is impossible to repeat.

Isnt a guy making a time machine that can take you to any time between the present and the time that the machine was switched on? And if you switch it off and then on again, it would be reset.

I heard the guy talking about it a couple fo years ago, it was interesting.

I'd like that, but seeing as you couldn't do much of anything interesting, it'd be purely for shits and giggles, methinks.

But something like that actually existing...I can't see it happening. Ever.

And if it did, and someone decided to make the world "better" by going back in time and eliminating Hitler...well...it'd turn the USSR into the big bad.

And then C&C would happen.

And that's a bad thing.

What? No, you wouldnt be able to go back to Hitler. You would only be able to travel to anytime between the present and since the machine was switched on. And as it is functioning yet and wasnt functioning 60 years ago, you most certainly couldnt kill Hitler.

Ah, sorry. I don't think I made myself clear enough.

What I meant was, if the type of time travel used/talked about/interacted with in any way whatsoever in almost everything (read: travel to any time period) existed, then if we went back to Hitler...yadda yadda yadda, etc etc etc.

After the first paragraph of my post I was no longer talking about the one you mentioned, I just didn't make that clear. At all.

Sorry 'bout that.

you could travel forward in time and not mess anything up

What your saing isn't that it's impossible, but that if it is possible, humans would abuse it and severely damage/ destroy the world or even the universe. I do agree with what you said in the OP, I'm just saying that that doesn't make it impossible.

As for my opinion, time travel is (in theory) possible, but the odds of it aren't that high.

Who cares. I'll be dead before I can get my hands on it.

Well, if it was possible, someone at some point in time would've gone way back in time and destroyed the universe, so we wouldn't be here right now.

But it would've still been possible to do.

No it wouldn't, because by destroying the universe in the past will kill whoever discovers how to travel through time, thus rendering the scenario a paradox, one which would rip the space-time continuum.

But for a short amount of time it would still be possible. Whilst the ability to travel through time would be removed from time, it would still be possible to do it before the history of the universe changes.

Also, this is based on the idea that someone would do something so extreme that it would destroy the whole universe. Due to the sheer size of the universe compared to our solar system (And specifically, our planet Earth), the butterfly effect could take billions of years to cause the effect that would destroy the universe. By the time the universe would've be destroyed, time travel could've already been discovered, thus the paradox would've been evaded.

Time is cyclical, a loop. Who say's we're the starting point? I'm not going to explain every detail of how this is impossible. If time travel were invented, then someone went back in time to a point where it was still invented, then there would be no paradox, since time travel would still be invented at that time. But if the person went back to BEFORE time travel, it would cause a paradox.

It would cause a paradox, but that doesn't mean it would've destroyed the universe/ earth/ wiped out humanity/ life, it just means that history and everything that followed would've changed. Sure they could've killed off the first humans, thus wiping out humanity including themself, but they could've just as easily claimed that they had discovered time travel and make money off of it.

There will never be time travel because time is here and now. You can't go back in time, because it already happened. There's no time 'line' more like a time 'dot'. It's already happened and is impossible to repeat.
