I'm sorry, but I completely disagree. I don't think Trunks re-appearing a while after he left implies anything of the sort. I haven't seen anything implying the Time Machine had that kind of "limitation" when it comes to the "trip home". Trunks simply sets a date when he goes in the past, and
I would assume that's
also what he does when he goes back to his future.
I already mentioned a couple of "in-story" reasons as to why Trunks would re-appear "a while" after he left, but I think there's a "real life" reason (as in, "a reason why Toriyama would tell the story that way") that's actually more plausible: making him re-appear just as soon as he left would merely be distracting ("wait, whuh?? oh, yes, it's
time travel! he
can do that!") and serve no actual purpose (if anything, it would even make the "Bulma/Trunks farewell scene" less dramatic, as Trunks pretty much wouldn't have left at all, from Bulma's point of view).
And of course, there would also be
that other "real life" reason, the usual one: Toriyama simply didn't think of that. Trunks left, so he came back later, "naturally". What do you mean, "time travels"? Oh, yeah,
that...
When you talk about time and the present you're refering to the 'now' and that the 'now' changes when you go into the past. Not so in the Dragonball universe as shown by the alternate time-lines. Yes, going back creates a 'now' with it's own new future. But the 'now' that you came from, your original time, is still there and still going since you've created an alternate flow of time.
See, it's the "still going" part that just doesn't sit well with me. The original timeline was never "going" anywhere. It's just... there. It's made of events. Points in time.
Unless you put yourself in the shoes of somebody in the future who's experiencing these events
one after the other, i.e.
living through these events, it doesn't make much sense to talk about "time passing in the future". And of course, if you put yourself in the shoes of somebody who's in the future... well, you're not really talking about the "future" anymore, since you
are now living it.
I mean, I, for one, certainly don't think in terms of "time passing in the past", for example. Do you? Do you think of these people who are currently (except
not "currently" at all, actually) living under Bonaparte? As if the time was passing for them? "Right now, in the past"? ^^;
Hmm, I'll use a river as an example. If you go back and create a divergence in the river the new river you made will snake off on its own. But that doesn't make the old river stop flowing passed that point. It's still there and still going, seperate and unique from the new river you created.
I naturally don't disagree with that. There
are two timelines
(well, there should be more than that, actually, but let's keep it simple), and we saw them both in the series. Trunks' timeline obviously
still has a future, even if he did create a new one by going in the past.
I just disagree with the way you put things... It just seems... "Trunks-centered"? Or maybe I should say "anthropocentrist", in general?
The reason why Trunks went back in the future a while after he left is because his future "couldn't go forward" until he spent some time in the past? Is that what you mean? I would think the entire future (I'm talking "billions of years", here) of his timeline is already there. It always was. It wasn't "waiting for Trunks" to be.
Or are you saying that the reason why Trunks went back in the future a while after he left is because his future "couldn't stay put" as long as he was spending time in the past? That goes back to your idea of "time passing in the future", but in that case, shouldn't the same be true for the
past?
If Trunks spends, say, 3 years in the future to recharge the Time Machine or whatever, are you saying that he wouldn't be able to go back in the past on the same day he left (for example), but 3 years later? Because "time passed in the past"? How does that even work? So he doesn't really get to select a date at all? How did he get to select a date in the first place? And, naturally, how did Cell manage to go
further back in time, then?
So yeah, I don't follow you. Maybe I simply don't get your point (in which case, feel free to correct me and precise your thoughts), but I can't understand why you would think the same amount of time
should pass in the future for Trunks to come back... as has passed for Trunks while he was having fun with his dad in the past.
They're just points in time, and (in fiction works, anyway) a time machine is supposed to allow you to pick one and simply "go there". You're alluding to limitations that aren't mentioned in the series, and like I said above, I
really don't see why you would think that the lapse of time between Trunks' departure and his return in the future "clearly implies" such limitations.
