the earth spins around the sun.
the sun spins around the milky way.
so if one where to time travel wouldn't they just pop into a space where we are now but where the earth hasn't reached yet?
Relativity tells us that there is no preferred reference frame. Earth is just as "special" as the center of the galaxy.
I thought John Titor was an innovative bit of science fiction writing. Did we ever work out who was behind him?
There was some speculation

Should add (2003) to the title
Were you disappointed that this wasn't bleeding edge advice for time travelers?
"What do we want?"
"Time travel!"
"When do we want it?"
"That's irrelevant!"
"Time travel!"
"When do we want it?"

If time travel is possible this may well be the state of the art

Predestination, starring Ethan Hawke, is a great adaptation of Heinlein's story too.
It was a great movie. Slow for about the first half doing a lot of character development, then moving quick into all kinds of territory, and then mindbending finish. I didn't know it was adapted from Heinlein. Darnit. Scratch it off my list of "original" movies to put it on "risky but good."
Also, worth mentioning that the actor playing "John" had one of best presentations I've ever seen. Smart that they picked at "tomboy" for it as that fit most of the movie really well. Also, showed John's more straightforward acting took more talent than one would figure at first.
EDIT: "All You Zombies." Extra obvious now. Wish I read it sooner. :)

Thanks, that's very cool!
A few links are broken in that article. Here's an archive which contains the pictures referenced: http://web.archive.org/web/20070202095050/http://www.anomali...
I assume the war destroyed all the decent smartphones then, along with the vaping devices. Those photos look worse than ones taken on my Moto G.
The civil war in Titor's time line started in 2004, well before the first iPhone. I'd imagine the war altered his timeline enough that modern smart phones with nice cameras were not invented.
Ha ha, hilarious. But the Nikon DSC 995 existed in 2001 and took vastly better digital photographs than that. Not only did the technology exist but I was using one in India around that time.
I suppose the one thing hoaxes can't really compensate for is the fact that technology moves so fast.

Could this have happened because some one altered the timeline?

I happen to be watching this right now, only to find this on the HN front page. The Organization is watching me!
that anime is the only reason i know about John Titor
For anyone else wondering, this is a reference to a password used in an anime called "Steins:Gate". No idea how it relates to John Titor.
Steins;Gate[1] contains references to John Titor[2]. I actually thought they had made him up until I looked on Wikipedia and discovered he was a real ("real") conspiracy theory.
An English version of the game is now up on Steam. Highly recommended. http://store.steampowered.com/app/412830/
[1]: Edit: the game. Not sure about the anime.
[2]: Edit: In the game at least this is more in depth than just a password. Saying more would require spoilers.

Welp, no linux version. A visual novel that actually got me interested. Hasn't happened in quite some time!
I believe there's a mobile version, and the first chapter is free.

No way my japanese is good enough for that.
It's a bit expensive for me to buy just for testing in WINE, but I think you'd have a fairly good chance of it working.
Thoroughly offtopic, would you recommend Steins Gate? I haven't watched any anime for a while but enjoyed Ergo Proxy and Eden of the East.
I can't speak to the anime, but I enjoyed and recommend the visual novel version.
I got into it because I wanted a break from more traditional games (such as RPGs) which may claim to have a story but often don't go deep into character development and so on. If that's what you want, Steins;Gate definitely delivers.
I'd make two cautionary points if you're going to try it:
1. It's a visual novel, so it's not going to be interactive like a more traditional game. You get some choices, which among other things determine what ending you get, but really don't influence much otherwise.
2. There's a lot of banter. You'll know in the first 10 minutes of the game if this bothers you or not. I personally didn't have a problem with it, but your mileage may vary.

I really enjoyed it and I would highly recommend it. It had the deep philosophical aspects to it but has a decent amount of humor to go along with it as well. I have been recommended the visual novel which i haven't read though. There is also a movie to go along with it.
https://en.wikipedia.org/wiki/Steins;Gate#Anime
The anime is very good, however it starts really slow and builds up.
The visual novel is really fantastic, though fairly slow-moving if you're not used to the medium. (Visual novels in general tend to be very detailed and very slow-paced. Some, like Higurashi, use this to great effect, but it can also annoy people not used to them.)
If you're not sure about reading it, the anime is also really good. It's obviously much less detailed than the visual novel (compressing ~40 hours of visual novel into TV format is hard) and omits some sizable plot points, but it's still great. The first half is fairly slow set up before it hits like a truck.

What would you recommend to try next for someone who liked Steins;Gate (the visual novel)?
For visual novels? Probably Root Double, Ever17, and Umineko. All have really great character development like Steins;Gate and are pretty thoughtful. Root Double has well-done sci-fi elements as well.
I haven't read the visual novel for either one but i've enjoyed the anime immensely. So I would recommend you give Haruhi Suzumiya [0] a shot.

I am curious as to why you were downvoted. I too am on the same boat and didn't know John Titor was based on `real` world events.
William Gibson's book "The Peripheral" is a fantastic take on this (and many other things).
Hahaha this is great! What I love about the John Titor story is how you kind of want to believe in it against your better judgement. The desire to be in on something larger than life, I suppose.
There is no such thing as time, or time travel. There are only positions of particles. To go back in time by 1 minute, all particles in the universe have to be moved/changed back to their previous position. This is not time travel, but universe manipulation except for one subject. If there were parallel universes with every possible outcome and you traveled to one, this would also not be time travel, but a moving to a place that looks like another place where particles were at a certain position. Time is just a way to label snapshots of particle positions in the universe.
Your position is inconsistent: the arrangement of particles changing is time, so your explanation of there not being time... asserts that time happens!
Putting the universe back as it was except for you is time travel. You've traveled your state to a different time (previous state) of the universe.
Your semantic game sounds very clever, but is actually just inconsistent and borderline ignorant of what people mean by those terms.

I think what he means is that time exists in the way that distance or speed exists. It's not a physical force like gravity or magnetism that acts upon the universe, it's just a method for us to understand and quantify what happens around us.
Traveling back in time subsequently doesn't make sense because the "past" is simply what we call previous configurations of matter.
You can't go back to those configurations (read: "go back in time") because they don't exist anymore.
Now, I'm not a physicist so I have no idea if he's correct, but semantically it makes sense and it's something I've wondered about for a while.

So? If my future goes from the world as it is now to the world as it was in 2000, in what sense am I not in 2000?
I mean, you guys seem to be under the impression that there's a single universal clock I cant reset... There's not. In whatever sense it ever was 2000, rewinding all the clocks would make it 2000 again. There's no clock besides those local ones, so if you reset them all, you're in the past (in whatever sense there was ever a past).
I just find it particularly silly to have said there's no time when you keep commenting on time happening.
(Also, does traveling a foot to the left not make sense because there's no distance, just past states Ive been in? Cause you said time was like distance, and you're right: both exist or neither exist in exactly the same sense.)

Unlike distance, time is unidirectional. Yes, if you could roll back all matter, energy and every other force in the universe you could "go back in time" but the point is that time is a concept and not a force of nature.
It seems like you're being obtuse about the distinction.
It seems like you're being obtuse about the distinction.
Your position is just semantic games: traveling to a past state of the universe and living there is time travel -- you translated your state in to a past configuration of the universe. You're just sitting there whining how what both scientists and lay people would accept as time travel (living in the past) isnt Real Time Travel, because it's not some fictionalized Platonic ideal you've constructed and insist is the One True Meaning.
Amature science people are the worst: a little knowledge keeps you from seeing the picture.

Your patronizing tone aside I see what you mean. Yes, that would be "time travel". Again, it just seems like you're being antagonistic here and now putting words in my mouth in a vain attempt to prove your own superiority.
The only claim I was making was to clarify what OP meant about time not being a phenomena like gravity and to passively ask if there was any evidence of time as a physical (rather than purely conceptual) force.
Sorry if my amateur curiosity offended your professional (?) understanding of such things.

Im mostly replying to say that you're correct I was needlessly antagonistic, and that Im sorry for that.
To try and answer your point a bit more directly: time isn't a force, just like distance isn't a force. A force is something that induces action. If you experience a force, you're induced to act. (Some debate about if gravity is a genuine force, but that's getting messy.)
Time is what a clock does, and distance is what a ruler does. On the one hand, both time and distance are mathematical fiction to parameterize aspects of the universal state. On the other hand, Im 2m tall and my clock is making a periodic tick noise. So, time and distance really are aspects of phenomena, rather than phenomena in their own right, and as such are fiction. However, the aspects of phenomena they refer to have so far turned out to be pretty useful and appear in most phenomena we've encountered, and we think this is because both emerge from aspects of the fundamental phenomenon interacting with itself to create the other phenomena. (This is why we're trying to unify QM and GR, and why the approach is based on entanglement and information cascades.)
My point was that there's no fundamental difference between time and distance, they're either both there or both not there in exactly the same sense, we can travel through both in the same sense (if not same freedom), but only very rarely do people get insistent that distance doesnt exist, and usually only when making a highly technical point. Never have I had someone not understand what I mean by moving a foot to the left, even if they ultimately don't believe that distance exists. This comment was like that: insisting we talk in the highly technical language of distance not existing, but refusing to make the standard and well understood lift of "move a foot to the left" to that language. There's a very straightforward notion of travel, even if we're talking about around a parameter space. It's that partial use of technical machinery that frustrated me -- if you're going to have a technical discussion, don't play obtuse and refuse to make reasonable translations if other people's statements. My comment about people who know a little was mostly just venting frustration that people who are new to the highly technical aspects often can't (and don't even realize they should) make those lifts, then end up stridently talking about how the unlifted claim makes no senae in their freshly learned framework. To be fair, I was worse about that than most, and should learn to be extra patient.
My snarky comment was snarky, but had a point: time is one of the open questions in modern physics, and unless you really want to get in to the heavy stuff, less is more. About the best view to have in your head is "there's no time but what your (and everyone else's) pocket watch says". Your watch needn't agree with mine, though. (And indeed, your head is a slightly different age than your feet, from all the standing, sitting, etc in a gravity well.)
To summarize, Id say that time and distance are meta-phenomena: they're consistently behaved, widespread features of phenomena we discover, but we have good reason to expect that it's an emergent feature of a deeper phenomenon.
Again, sorry for my earlier replies, and I hope I havent put you off asking questions!

That doesn't sound right - traveling back in time should also 'replay' random events not directly affected by the position of matter, such as radioactive decay.

I don't think that's how most people think of time travel.
For example, say I proceeded to invoke reactions to get all particles back to exactly how they were on Jan.1 2000. Say this took me a year, and finally, in 2018, I execute the final reaction that places the last particle, so that the universe is exactly like it was Jan.1, 2000. Have I been time travelling for a year? Does making 2018 look like 2000 what people generally think of as time travel? What about that you yourself did not change, where are those particles coming from? What about the old you existing in that time as well, there aren't enough particles in the universe to have two you's. What about the time you travelled from remaining in existence while you're gone, and the changes you invoke in the "past" propagating there?
I get that it would provide a similar experience in many ways, but it doesn't involve travelling, nor time, just changes in particle positions - which is the nuance I am highlighting.

You have to give up the idea of a universal clock: you only have a local one.
In your example: since you erased the elapsed computation in other regions, you (by putting the particles back) are literally rewinding every clock but yours.
In whatever sense they were ever in 2000, they're back there, though you're in (your) 2018. Having your 2018 be their 2000 seems like a sensible definition of time travel.
(And yes, you'd have spent a year time traveling, though in many senses you always are time traveling forward, and you just happened to spend a year going fast "backwards".)
For the rest of your points, I agree that they're sensible objections to being able to do it, but they don't make the concept not mean anything, which was your original point.
Why would the future remain? You destroyed it when you time traveled, and any changes in the future would require time traveling forward to see. (Forward is less erasure heavy, because you're just stalling instead of rewinding.)
It's not just a similar experience, it's the literal definition of what that term means.
> nor time, just changes in particle positions
Uh... It's comments like this which makes me question your position.
Changes in particle positions is time! Literally: time is just that thing a clock does, which is tick. If particles change position, that's (by definition) time.

Time travel is dubious, but in what useful sense is there no such thing as time? Define the phenomenon of time dilation or just the concept of motion without it. Particles go from position to position... but describing being at state X and then being at state Y seems to strongly imply the existence of what we understand as time.
Time doesn't exist in the sense that it's just a measurement. I'm 6'2", that height does not exist as a tangible thing, it's a mathematical device.
Whether we're talking about 60 seconds, or 6 billion years, they're both measurements of distance traveled / motion. We measure one year by the earth's relationship to the sun.
Time travel cannot exist because the universe does not keep a record of where everything was at any given point in time, such that you can rewind (adjust) it all back to how it was at every or any given point in time. There is nobody recording that, there is nobody to rewind it, there isn't enough energy to attempt either the recording or the rewinding at an independent macro scale (eg could you properly rewind/adjust a solar system while the wider galaxy acts upon it? would you have to rewind the galaxy? and on it goes up).

The argument about time seems plausible. I don't think time travel is possible either. I do however think there is such a thing as time and height. Units of measurement are certainly arbitrary but there is something that is being measured.
OTOH time is relative to the observer and certain universe phenomena, such as black holes, can distort how time passes in different points of the space dimension. The general idea that a point in time is how we define a particular snapshot of particles is probably right, but time as a dimension also appears to be a bit more complex than how we perceive it from Earth, which we should also not forget.
"Time", aka chemical and physical reactions, can happen faster or slower depending on the environment. But this is only slightly different than putting food in the fridge. The food will mold slower, but it's not time travel.
The closest we can get to faking time travel is by manipulating the speed of a subset of reactions (like our body's aging) by going the speed of light or freezing ourselves, etc. But it's still fake, "time" continues, you just managed to manipulate specific reactions in a peculiar way.

So special relativity, which is a theory that comes out of thought experiments and pure mathematics, is "just a chemical reaction". How do you explain that an observer outside of a moving frame of reference will also see things differently?
Also, can you explain what you think "physical reactions" are? What causes them? Why would they happen at different speeds if time doesn't exist?
Can you explain which of the two statements you disagree with and provide an explanation:
1. The speed of light is constant in all frames of reference.
2. The laws of Physics apply in all inertial frames of reference.
If you disagree with neither of these statements, then the entirety of special relativity must follow from your logic. Which means you have to explain why these physical effects happen without being able to explain it through time dilation and other effects.

How do you explain acceleration? Or things like entropy that appear to indicate that the "arrow of time" does exist. Or general relativity / cosmology that clearly shows that your "snapshots of particles" appear different in different frames and there are physical effects that change how time progresses for them all.
> Time is just a way to label snapshots of particle positions in the universe.
You're not saying anything new here, apart from saying that "time isn't real". Is any dimension real? Spacial dimensions are even weirder because they're unlabelled and you can pick and three vectors to define a basis.

You are wrong. As far as I know, each particle has is own time. Each particle can go forward on time, independently.

You make a good point. What if a civilization figured out how to do this on a local level? To finely manipulate particles within a small area? It would be like version control for reality.
This idea is referenced quite a bit in an Asimov novel, but I can't remember the name. Something about earth in the far future, and called Eternity Circuits. Computers enforce physical arrangement at an atomic level, and redundancy circuits enforce the computer and each other, basically creating systems that last forever.

Each particle has is own time. Each particle can go forward on time, independently.

Why even bother with this whole pointless facade? Just because you have a preferred model of time doesn't mean it doesn't exist. All things that are said to exist do so as models.
You're saying "time is fake, it's just labels" like somehow everything else in the universe isn't also just labels and just as real. Things are what they are. You find a useful way to talk about them. You don't spend your time laboring over meticulously irrelevant descriptions, ironically putting down 'mere labels' as though your whole argument here isn't just a grand exercise in label worship.
One could fairly trivially write a faithful version of your post on literally any subject. "Position doesn't exist, it's merely a manifestation of the relative relations between subsets of human experiences!" "Your HN post doesn't exist, it's merely electronic patterns in a transient configuration!"

> this... would not be time travel, but... a different time.
Hmmmmm.
Hmmmmm.
He probably should have said 'not time travel but a different world'
That's what different times are.
Does anybody know if the forum archives with John Titor's posts are still floating around somewhere? I remember reading some of his stuff a few years after he disappeared and it made for quite an entertaining read. This guy had his story figures out to the very bone. Everything down to the sci-fi tech. He had every nook and cranny covered.
If you really want to be believed, just show up to Stephen Hawking's time traveler party he held in 2009[0].

Interesting fiction. I'm not physicist, but anything pumping out enough gravity to bend a laser beam 45* over a couple feet (see pic in link) should also collapse that car into a sphere. I also laugh at seeing that while the laser seems bent, all the other light passing through the same area seems unperturbed.
