Limits of Time Travel

Why aren't more people using time travel to cheat death, or multiply themselves?

Why doesn't the Federation use time travel to create Temporal Clones of its best ships and officers, during war time? What's stopping 99% of grief stricken people from using time travel to change fate? Why isn't anyone attempting to use time travel to cheat death forever? What reasons, other than "muh Temporal Prime Directive/Preserving the Timeline."
Isn't this what the (mostly unseen) Temporal war in ENT was about? We saw various versions of Daniels die but he continued to crop up. That's cloning.

And Janeway did the grief thing in "Endgame"
 
It's like Roger Rabbit slipping out of handcuffs. He explains that he can only do it when it's funny.

You can only create time clones, transporter duplicates, transgalactic wormholes, or other crazy Star Trek crap when it's entertaining to people.
 
It seems to me that the rules are different, depending on whether it's via the Guardian of Forever, the Atavachron, a slingshot effect, an implosive cold-restart of a warp drive, whatever Daniels uses, whatever "Future Guy" uses, whatever the Aegis uses, or Georges Mordreaux's device from The Entropy Effect (did I leave anything out?). Which probably makes the DTI's job harder.
Berlinghoff Rasmussen's time-pod, the Orb of Time, the Nexus, Future Harry Kim's Borg temporal transmitter, Future Janeway's Chrono Deflector, whatever the Borg used (could be the same as one of the previous). Almost certainly there are more.
 
Will you accept “Story convenience” as an explanation, or do you want an in universe reason?

Probably all of the governments that can do time travel are aware of how sensitive time is and how easily you could destroy the future. Just like (Makes sure Picard has been out six months) the Romulans have a secret organization that shut down android development they probably also keep tabs on time travel. And Klingons seem to have some sort of offshoot group.

So that’s my answer. It’s a deep state conspiracy that all deep states of all major governments separately arrived at to shut down all time travel research to prevent exactly what happened in the temporal Cold War. And why once Pandora’s box was forever open, they established a division of Starfleet just to protect history from time travelers.
 
As I recall, in ADF's adaptation of "Yesteryear," he painted a rather rosy picture to the general effect that the Federation, Klingons, Romulans, and possibly other major powers cooperated in guarding the Guardian against misuse.
 
Time travel to the past is, I think, impossible. Ignoring the paradox problem for a second, if I travel back ten years to meet myself, where did that extra matter come from?

Time travel to the future (via dilation) is not only possible it’s already happened.

Eh, the universe gets a little more mass for about ten years. It'll fix itself when an equivalent amount disappears. Happens to me all the time.
 
We don’t really see any of these anywhere in the Star Trek canon, apart from the currents of time thing that’s theorized about the guardian of forever.

For me the only real risk is that changing the timeline is really dangerously easy and it’s not so easy to correct the damage once it’s done.
 
Maybe those civilizations that have mastered time travel soon discovered that it creates more problems than it solves. One little foray into time (specifically the past) could potentially cause multiple butterfly effects that could wipe out any benefits it could have.

No wonder why Temporal Investigations had a big file on Kirk...
 
Sir, you may have just struck gold for me! If I decide to use this issue on my story I will credit you!

Well that's very nice, but I can't take credit for The Law of Conservation of Mass.

;)

Also (and I'm obviously not a physicist) you also have the problem of Entropy. As one professor explained to us: "how many times have you made breakfast? And how many times did the eggs spontaneously jump back into their shell? The bacon rejoin the pig?" Time simply does not flow backwards. We don't grow younger, etc. because of Entropy.

I don't think Entropy allows for time travel to the past. Time Machines Would Break Second Law of Thermodynamics.

George Washington is dead and buried and probably decomposed to a great extent. What machine are you going to build so that isn't the case? Where would that machine go where he's alive? What would the machine do to get there? How would you "steer" a machine like that? Sci-Fi always shows a dial or a lever or an LED display where you "choose your destination (i.e. "date"). But they never explain how you point or steer your machine. Because the idea is really pretty silly, if you think about it.

Fun for science fiction, but I'm going to stick to the idea that time travel to the past is impossible. JMHO
 
In 11/22/63, a guy time travels to the past repeatedly and buys the same pound of hamburger again and again. Presumably the dozens of parallel timelines he created each lost a pound of hamburger while ours gained a comparable number.
 
If time travel exists I don’t think it violates conservation of mass or increasing entropy. It just means they apply over more dimensions than 3.

What I don’t buy is either of the explanations that either you can change the past, or that you can go back but will just end up causing the events you planned to stop.

The first case seems the most impossible. Cause if you stopped yourself from being born you also stopped yourself from stopping yourself from being born.

The second case seems explainable but you have to say something like “If you changed the past the universe would be unstable and could not exist, so the fact the universe exists proves that it is stable and whatever you chose to do didn’t change anything”.

The third option is close to what they did in Agents of SHIELD invoking quantum uncertainty to allow different timelines to exist, and it seems the most likely if time travel were possible.
 
So for those who believe the past will correct itself if something is changed, doesn't that imply there is a conscious mind at work? God? time cops?
