When has it ever done the "multiple universes" thing?
Parallels comes to mind.. weren't there different timelines and different events occuring (like one where the Borg have taken over everything?)
Parallels had nothing to do with time travel. It's a common misconception that's cropped up around these parts. Yes, there are multiple parallel universes in Trek. The episode explained this is a result of the universe branching every time an electron needing to decide between two states. Furthermore, they demonstrated the ability to detect when matter was from the wrong "quantum reality". They noted that everything in one universe will ressonate with a particular "quantum signature", and that Worf had a different one from everyone else on the Enterprise.
If this phenomenon had anything to do with Time Travel, then those crew members who had undergone time travel events would have had a different "quantum signature" from the rest of the ship, but it was explicitly noted as only being Worf.

There was another one. What about that one where they meet the Enterprise-C? I thought that was multiple timelines too.
No, actually. The Enterprise-C incident is actually evidence against the multiple universe theory.
We see the time-travel event from an outside prospective, and the moment the Enterprise-C is removed from its proper place in history, the present is visibly altered. Guinan notices the timeline shift as it happens, as a kind of intuition. She recognizes that history has strayed from its proper course, and needs to be righted.
When the Enterprise-C is returned to its proper place in time, the grimdark future we spent most of the episode in is again visibly overwritten, and again Guinan notices something has changed, but states that things are as they should be.

There's other cases that have been brought up before, like when people go back in time but never seem to meet themselves (Captain's Holiday, etc.)
Why would the time travelers in Captain's Holiday be expected to meet themselves?

or I imagine in cases where time always repeats itself (There was at least one case in voyager like that wasn't there? Time and Again I think?)
Time and Again followed standard Trek time travel rules, and actually offers the same evidence against multiple timelines that was present in Yesterday's Enterprise. Kes had the same sort of intuition of a timeline alteration that Guinan had.
In this episode, we have a standard time-travel incident where Janeway and Paris end up in the past, do something to alter history at this point (specifically, preventing the explosion that led Voyager to investigate the planet in the first place), then things progressed from there with Voyager moving on, likely leaving the temporally displaced copies of Janeway and Paris on the planet, assuming they weren't killed in the rioting or the energy discharge from Janeway's phaser interacting with the rift.
There are a few lose ends about the first cause of that episode's time travel event, but it's clear we're not following events from before the first time-travel incident in that episode.

We know the warp slingshot maneuver can get a ship and crew back or forward at least four centuries, because we've seen it do so on at least three separate occasions.
We know that changes to the past effect the present, because every time travel event except the All Good Things one (by act of Q) have resulted in changes to the present whenever the present was observed after the time travel event.
What more do we need to know about how it works?
Because we get back to the whole "why do they not..." That isn't a trivial issue. Time travel as a capability is demonstrably useful, and as such it should have an impact on things far greater than it has if it were common place or easily achieved. That it is not suggests there are limitations of some king, either iwth how it is done (such as it may be only done in certain locations), or some external force (like the 29th century feds and others) may prevent certain activities from happening (which is why people don't fuck around with time all the time.)
We do know that there are certain limitations on the Warp Slingshot maneuver. You need a ship equipped with warp drive. And you need a large gravitational mass like a main sequence star or a black hole. Without one of those two items, you can't make it work. We know for certain that the Earth's sun is an appropriate location, because it has been used on three separate occasions. The only time the slingshot maneuver didn't use the earth's sun was the initial accident when it was done around a black hole.
If the 29th century feds are preventing temporal shenanigans, that leads to the question of why they haven't prevented them every time. And we thankfully have an answer for that which is quite satisfying.
They don't use the Temporal Prime Directive as it's defined in the 24th century. They don't care about maintaining the original timeline. They care about something they call "the preferred timeline". Basically, if a time travel incident makes things better, it stays, and if it makes things worse, they intervene. That's why Admiral Janeway's timeline where she fucked over the Borg and handed over future tech was allowed to stand, why the computer revolution spawned by Braxton's misadventure was left in place, and why Voyager itself was required to be dumped back in the Delta Quadrant rather than left at Earth.
We can point to the fact that our heroes managed to undo temporal damage on their own as a reason for the 29th century timecops not showing up to fix things before our heroes can try themselves in a dozen different time travel episodes.
If you want to posit a limitation beyond what we've seen on screen and the basic good sense of everyone involved not wanting to fuck with causality except in extremely dire circumstances, you're welcome to do so, but I think what we have is quite adequate.

I should also point out that time travel also creates problems with canon, if going back in time changes the past or anything. How could we be sure things in past epsiodes hold true if things have changed? Time travel would be hard to predict that way.
I'm afraid that's just an unavoidable hazzard when dealing with a series where time travel works.
If it's any consolation, every time travel story except J J Abrams' most recent clusterfuck had the decency to clean up after itself.

If D13's example, why would they want to go back farther?
Again the "why don't they.." argument. Why not, for example go back and stop the borg? Why not go back and stop the dominion?
Because it turns out they didn't need to.

Why do other powers (like the Klingons, CArdassians, Dominion, etc.) not do it?
Do we know for sure the other powers have access to time travel?

Why don't the borg do it more (they did it once and got away with it, why not again?)
I want to know why they tried it this time. It doesn't fit with their MO or stated objectives. There's no tech to steal in Earth's past.

We don't know where or when Palpy was born. I noted this in my explanation for why I'm not adopting assassinating past Palpetine as a major element of my defense strategy.
But you can go back in time. all ya gotta do is keep going bakc over and over until you do find him, and finish it. Use one of the myraid planet-destroying technobabble options available to trek, fuck with a star, etc.
This is also known as the "all your eggs in one basket" defense strategy.
To pull this off, you need a ship and crew equipped with a drive system that can take them anywhere in the Galactic Empire, enough information to blend in with the past timeline, the tools to track down the hidden secret identity of Darth Sideous without tipping our hand to the Dark Lord of the Sith about what we can do and without any of our temporal manipulation technology falling into his hands at any point in the past before we're aware of his existence.
If we can get a copy of the Dark Lord's unofficial biography with a historically accurate account of his life, this strategy might be worth it, but as it stands, we stand to lose too much and gain too little.
Like I said earlier, if I'm going to alter the history of the Galactic Empire, my preferred incursion point is going back and getting Padme prenatal care.

It just makes it harder. It doesn't make it impossible. But if you have no limits on your time travel whats to stop you from keep redoing things until you do get it right?
Past Darth Sideous murdering my time travelers and stealing their ship.

Why would I want to? We aren't at war with the old Republic.
Because the Republic becomes the empire. Destablizing the REpublic should be far easier than fucking with the Empire. And its another way to assasinate Palpy.
Destabilizing the Republic is what got us into this mess to begin with. If the Republic were more stable, Palpetine wouldn't have taken over and we wouldn't be facing an Evil Empire.
Connor MacLeod wrote:
If time travel doesn't work, why is it ever used at all?
It seems to be that the lack of military uses of time travel by either side of a war involving the major powers is akin to the lack of battlefield deployment of nuclear weapons since World War II. Star Trek is a cold war analogy, and everyone knowing better than to bring out the big guns, for fear of the Russians bringing out theirs, is all the explanation I need. Arms control treaties canonically exist in Trek, after all.
Ah the "stupidity" excuse.
Because it's stupid not to deploy nuclear weapons in our current wars...?

That works in some cases, but not in others. (CF the Borg.)
What does the Federation know about the Borg's history? If they went into the past, how would the Federation strikeforce find and identify the Borg homeworld before they became the Galaxy-wide threat they've become? How would that strikeforce even cover the vast distance required to get to the presumed location of the Borg homeworld in the Delta Quadrant?
If you want to call them stupid for not doing this, it only works if you've already got all the particulars worked out.

Also we've seen individual Klingons using it that way (Trials and Tribble-ations) - why would one klingon figure it out and not others?
You'll note that said lone Klingon
criminal was not acting with the approval of his government (arms control treaties, etc.) and was using a time travel mechanism that gives no indication one way or the other what time travel tech the Klingon Empire's military is sitting on.

And IIRC the slingshot method from the TOS movies is still well known in the TNG era. Why dont' one of the more militant/assholish Federation types ever use that?
Do we know he didn't? Do we know that he didn't also fuck up, realize the error of his ways, and set things right? A lot of stuff happens off-screen. We're only following one ship and crew most of the time, after all.

What about it? I'm not objecting to the industrial or power generation figures we're using here. That's why I, as Supreme Commander of the Federation's defenses, am not prosecuting this as a conventional war. Because I know and accept that I would lose a conventional war. Thus my only hope is to use unconventional tools.
Tools that would normally be considered too dangerous to use in conventional wars against neighboring powers.
Besides, we don't have an arms control treaty with the Empire, and it's not like they're going to agree not to bring their big guns to the party.
Actually some good objections were raised ot it, because assuming that DS Mass = millions/billions of ISDS or scaling down ISD firepower form DS fire power (oor power generation from power generation) is overly simplistif and ignores other variables/problems. Which it does. I believe D13 has amde this argument in the past
And I'm sure those were very interesting discussions, but for the purposes of my defensive planning, I'm going to assume that's what we're dealing with. If nothing else, the massive population and industrial edge alone is enough for me to need to resort to drastic measures.

If we have humpback whales, there is no such thing as lost tech.
That just creates other problems. "Why don't they.." arguments are annoying and they arne't always applicable (and are overused I'll admit it) but that doesnt mean they can be ignored or will go away, because sometimes they ARE applicable, and if you don't consider it you end up inventing abilities that one side doesn't exist. (It's happened with B5 First ones for example, used to inflate their abilities up to face other powers like the Time Lords, the Culture, etc.)
Sorry, but when earth was in danger, and the only thing that could save them was the "lost technology" of the language of humpback whales, they damn well used time travel to retrieve that "lost technology". It happened. It was a great movie.
Can you think of any particular incident when such "lost technology" is so absolutely vital that they didn't go back and grab it? If you want to get into "why don't they" arguments, that's fine, but what didn't they do that you think they should have?
