I like to think that if AU Kirk and co. went back to 1968, they'd bump into their TOS counterparts. I can't see that actually happening should the episode be adapted, but it would be fun.
I think this has been raised before I'm just not sure where, but since Kirk and the U.S.S. Enterprise (NCC-1701) are obviously different, then it must mean that "Tomorrow is Yesterday" as the original episode stands cannot have happened in the Abramsverse, right? 1968/2268 in the Abramsverse must have happened a different way.
I don't think so. Remember, the Abrams timeline and the Prime timeline coexist side by side. It's not a case of one "replacing" the other -- the timeline branches into two parallel tracks, like a fork in the road. (Well, many more than two, but only two concern us at the moment.) So if time travelers from either timeline go back to before the fork, they'll end up in the same original track -- at least until their actions in the past cause a different timeline to branch off from that earlier point.
So the event of the Prime Enterprise going back to 1969 in "Tomorrow is Yesterday" (along with going back to 1968 in "Assignment: Earth," going back to 1930 in "City on the Edge," going back to 1986 in The Voyage Home, etc.) is still there as part of history. If the Abrams Enterprise went back to that exact same moment, they might run into their counterparts; but if they went back at all, odds are that they'd arrive at a different time and their differing actions would cause them to branch onto a different track.
That's not quite correct. There is no 'fork' per se; the timelines are separate even if they appear to be exact so no, NuKirk cannot go back and meet TOS Kirk in 1930.
Of course if you accept that premise then McCoy was not changing the past at all in the original episode but rather causing those in the vicinity of the Guardian to 'jump tracks' along with the person that has been sent back. In that respect the time traveller is changing the history of the observers by making them part of the alternate timeline.
So yes, there is a fork in the road.

You're stating a variant fan interpretation as though it were gospel fact. The intent of the filmmakers, as we know for a fact, was that the Abramsverse diverged from the Prime history as a result of the Narada's arrival in 2233. Prior to that moment, they were the same timeline. Certainly I've heard many people argue that it could have been a separate timeline to begin with, but that's just a supposition, not a proven fact. Therefore, I am sticking with the presumption intended by the filmmakers, until I'm given canonical evidence to the contrary. (The comics don't count.)
I think you're making the mistake of assuming that alternate timelines are just near-identical parallels that have always coexisted alongside each other. That's not the way it works, quantum-mechanically speaking or fictionally speaking. They only run in parallel after the event that causes the divergence, not before it. So yes, there is a fork in the road.Of course if you accept that premise then McCoy was not changing the past at all in the original episode but rather causing those in the vicinity of the Guardian to 'jump tracks' along with the person that has been sent back.

Well, sort of. If the timelines were the same and there were an infinite number of alternate realities, in at least some of those realities, people would travel back in time to points before the divergence.
When you have infinite possibilities of every split second, you would, as people are saying, end up with a massive, MASSIVE bottleneck. Think about it - every intelligent being that has ever existed will, in some realities, develop time time travel and in at least one reality, every one of those will travel back to the same point in time at the same location. As a theory I just think it's untenable.
The other possibility is that the act of time travel automatically creates a divergence at the moment the time traveller arrives so the concept of pre-destination paradox goes out the window, which would be a shame i.e. Data could never find his head in a cave because when they went back in time they would create a fork and a new future.
IMO if every possibility exists as a quantum probability then you've had multiple possible timelines running parallel since the birth of time with multiple copies of the most probable outcomes.
And we're only talking about physics. For all intents and purposes the identical timelines ARE the same but travelling back in one of them does not change the future in every other or you end up with the temporal police and nobody wants that car crash of a concept.
If the NX-01 would travel into the future, would it be predictable which future it would arrive in?
And if it travelled more thantonce, would it see the same future or randomly bounce between possible futures?
To make the relevance to this thread more obvious: which NCC-1701 would be the one Archer encounters?
(Maybe Enterprise could have a choice of futures?)
So in any work of fiction that's about people from one timeline/universe actually travelling to or interacting with a different one, we must be dealing with a finite set of realities whose similarities are not the result of random chance but are instead due to a common origin.
I know the comic series that this thread is about has embraced the "infinite alternates" model, but it just doesn't work.
Also, if you're going macroscopic and talking about the range of possible decisions that a given person could make, then that's even more finite, because our choices are a lot more constrained by circumstances than we like to think. For instance, if you're at an intersection and you turn left instead of right, that's because you have a reason to go left. A prior set of circumstances led you to that decision, so the odds are you'd go left in most parallel timelines. And even if there were some where you did turn right instead, there would be none where you went straight up into the air or straight down into the Earth. Your choices are constrained to a finite few by your history and circumstances. So even talking about "infinity" in a context like this is invalid.
So just because timelines can branch, that does not in any way prohibit a self-consistent loop. It's just a matter of the specific context in which the event occurs.
That's true enough, but the point is that it does still allow for a single timeline to continue branching. And that's what we're talking about when we discuss time travel. As a rule, traveling back in time sends you into your own past. It doesn't spontaneously jump you to some alternate past. And if you then take some action in your own past that causes events to change, then you create a new branching off of your own timeline. This is the way it's almost always assumed to work in fiction, and certainly in Trek. And I can't think of anything in real theoretical physics that would invalidate it. Yes, other parallel branches already exist, but they aren't relevant here, any more than the other branches of a tree are relevant to whether a particular branch grows a new twig.IMO if every possibility exists as a quantum probability then you've had multiple possible timelines running parallel since the birth of time with multiple copies of the most probable outcomes.
What? Of course it doesn't change every other. Why would it? The whole point of parallel timelines is that they don't interact, as a rule -- no matter how similar they may be, they are unaffected by one another and behave as if they were completely separate, isolated universes. Only very unlikely, exotic physics would allow any exceptions to that rule.And we're only talking about physics. For all intents and purposes the identical timelines ARE the same but travelling back in one of them does not change the future in every other or you end up with the temporal police and nobody wants that car crash of a concept.
Any theory has to work off a set of assumptions that are not wholly consistent consistent with canon. It isn't possible to pin down a correct answer as a result.
And just because one person in isolation has no reason to turn left does not mean that if some other person gives him a reason he will turn left. Butterfly Effect 101, with a near infinite number of variables throughout the universe.
Attempting to limit that to a much smaller number is an arbitrary assumption.
And we don't know for sure that there are a finite number of particles in existence once the multiverse is taken into account.
And who or what decides what is consistent with one's own past to form a loop if the very act of going back changes one's past?
We should all just follow Janeway's example and accept that temporal mechanics make no sense.
So you're saying that it would not break any rules of Star Trek (novel) physics for a future work to have Lucsly and Dulmur forcibly granted some kind of longevity/immortality and be held hostage as they helplessly witness a Federation apocalypse in spite of all their experiences in Watching the Clock?If the NX-01 would travel into the future, would it be predictable which future it would arrive in?
Probably not. Generally in Trek, when we see people traveling to or getting glimpses of the future, it turns out that it was just "one possible future," because the writers don't want to limit future storylines. (Which was why they went right from making a series finale where the Enterprise-D survived decades in the future and had three nacelles to making a movie where the E-D was destroyed less than a year later.) Presumably it would be their most probable future, or one of them. Or, as is often the case in fiction, the future that will result from their current circumstances if they don't prevent something based on that future knowledge.
There's actually a lot of solid theoretical physics about time travel and alternate histories that makes plenty of mathematical sense, and that's what I use as my guide. It's counterintuitive, yes, and very different from everyday experience, but that doesn't make it nonsensical.We should all just follow Janeway's example and accept that temporal mechanics make no sense.
Technically going by Christopher's system, it should be Data's head with all his memories up until season 6 of TNG which is sitting under San Francisco in 2259 of the AU. And that's probably one of the coolest things ever.
