Why didn't Fut. Bulma tell Fut. Trunks about Gero's Lab?

Time travel creates a bunch of plot holes. I wouldn't put too much thought into it because you could spend your whole life and not exhaust the possible plot holes that are created by time travel.

Time travel differences between the two timelines is a possible explanation for the plot hole, like mentioned. Also, I think you are confusing time travel paradoxes with plot holes.

Though in at least one timeline, it may have led to Trunks beating the Androids by Bulma building a remote to shut them down.

It's also the same timeline where Cell kills Trunks and steals his time machine.

There are still numerous other issues created by time travel like how Trunks comes back in time, creating a new timeline but returns to his timeline instead of the future of the new timeline. For stories, paradoxes are essentially a type of plot hole since they are contradictions.

You pretty much cannot have time travel without plot holes.

EDIT: Beaten to the punch!

That's not explained but we can assume that the machine works that way. Dragon Ball seems to follow the theory that paradoxes created by time travel create new timelines instead of overwriting existing timelines. The machine returning to its original timeline to a point in time after it had traveled back in time, doesn't create a paradox.

These are standard theories regarding time travel in fiction and whatnot. But yes, time travel is something so weird that its pretty difficult to make everything have sense.

However, this is completely offtopic. The point of the topic is to explain why Future Bulma didn't tell Trunks about the lab's location.

It's a standard trope but one that's illogical. I'm not putting it down, but you have to be willing to suspend a lot of disbelief in order to enjoy the stories. I don't think it's completely off topic. Completely off topic would be talking about what Bulma's best haircut is (I'm just bein' funny, not sardonic). Talking about the pitfalls of time travel in fiction is a logical extension of the topic. So, to answer the question, either the lab moved, which is very possible considering everything else that's changed, or Toriyama didn't give too much thought to it. I honestly don't blame him either. I've been watching DBZ for 20 years and it was only now that this story point was brought to my attention.

My guess is that Bulma searched for the lab when Trunks was still a baby, only to find it destroyed.

Toriyama forgot isn't an in-universe explanation though.

Then how's that a plot hole? "near" is vague, and even if she specified the mountain ranges near the city, finding a hidden lab in a mountain range would still be difficult.

If Future Bulma knew that Dr. Gero lab was near north city, she could have sent Trunks to stop him from building the androids. Not knowing exactly where it is, doesn't really matter because she has a time machine. If she sent Trunks back in time one month after Goku returned, Trunks would have almost 3 years to find the lab. Knowing that its near north city would be more than enough to find it. In fact, when Present Bulma told everyone it was around there, they immediately went to find it and got extremely close to it even before they found Gero entering it.

Isn't that sorta what happened with the Trunks from Cell's timeline? Trunks was planning to go back in time a year before Goku's return to look for Dr. Gero's lab.

And I'm sure they were only able to find it because Krillin saw Dr. Gero going in.

I wouldn't mind, if this becomes the official answer to this confusing matter.
It actually makes a bit of sense.

I don't know. There's some strange people out there.

Not to mention that the lab could have been destroyed like in the present timeline, and Bulma wouldn't think to look for an underground bunker like they did in the present timeline because no one would tell them about it like Cell did. And there's also the fact that they wouldn't think it's safe to look for extended periods of time due to the Android treat in the future timelines (The lab could very well be the Android's home). Or the fact that they could have simply given up looking for it and thought the lab was no longer there (Focusing their attention instead on the Time Machine) since Bulma did thought Dr. Gero probably moved places. Or Bulma simply didn't think of the lab's location due to timeline changes. Or if Trunks found the lab, he wouldn't find the blueprints still and wouldn't think to search for the entrance to the underground bunker for reasons already mentioned (Didn't know about it).

But then again, the Trunks in Cell's timeline already figured out how to kill the Androids. Meaning he already knew about the shutdown device.

Ah well. As previously mentioned, Bulma had so much faith in Goku. Also, the Bulma from Cell's timeline probably thought that changing the events of the past would change the events of their own timeline, so she'd think by telling the others in the present timeline about the remote device, it would save everyone.

How did you come to that conclusion? Nothing implies it at all. The androids had already been defeated in his timeline, so Trunks would have no interest in going because, even if he did, all he would do would be create yet another changed timeline.

[Alex9196]

I never thought of this scenario, but I always wondered, after Piccolos death in the future Kami would obviously die to. But I dont think Mr Popo or Kami's place took any damage. But Mr Popo can sense what is going on on earth. So I wondered why he didn't search for Future Gohan and Trunks and told them about the Hyperbolic Timechamber. Then after a day they would come out kill the androids with ease and the future is safe. And after a few years they also could have killed Cell.

Yeah, I realized that a bit too late.

Oh well, there are infinite numbers of timelines after all. Perhaps Trunks did went back in time to look for the lab in one of them. Also, one of the main reasons Trunks went back in time in the first place was for the satisfaction of making a world where the Androids didn't wreck havoc, which lines up perfectly with Trunks going back in time even though he'd be creating another timeline. And there's also the fact that the timeline changes in Cell's timeline could have led to Bulma and Trunks instead believing they could alter their own timeline by changing their past. For example, the Trunks that came to the main timeline wasn't certain that his own timeline couldn't be altered until he went back to his own time to find out Goku is still dead despite giving him the medicine. So there's a great chance that any of the Trunks' from the other timelines believed that their own timeline could be altered by changing the past.

My previous posts gives more insight on the whole lab situation.

Well, to be fair, the Hyperbolic Time Chamber really wouldn't do much unless they decide to try figuring out a way to go beyond Super Saiyan like the Z-Fighters did in the main timeline. And there is a high chance that the Androids would find Kami's Lookout on their own (Way easier than Trunks' would for Dr. Gero's lab). A tall tower that extends to the high skies would be sticking out like a sore thumb.

They would need one day.

And the Androids had no intention of killing them. Besides they dont know that they can go up there and get 1 year of training in a day. They had chances to kill Gohan and Trunks and let them go. Why wouldn't they allow them to go to a tower?

Not really. It's like saying they could also achieve the MSSJ during that day. The only reason Goku and the others needed a day was because that would be enough time for them to look deeply for a level beyond SSJ. Since they never tried it beforehand. Not because they need another year of getting stronger to achieve the levels. They've been living in the apocalyptic world for over a decade, I doubt Popo would think another year would make a difference.

The only reason they spared Gohan and Trunks was because they made for good play things, not because they wanted a challenge like Perfect Cell. So they'd have no reason to spare Kami's Lookout, let alone allow Trunks and Gohan to enter the Time Chamber.

Also, It's not like the Androids themselves knew about the Time Chamber. Chances are they'd blow the place up without knowing of it.

[supercat]

A full year's worth of training crammed into one day with undivided attention would have likely given them what they needed. Because they were constantly subjected to catastrophic events for the past decade, they were never given quality time to exclusively focus on their training without any disturbances. Even if they don't go beyond the limits of a regular Super Saiyan, the sheer power increase itself would have been enough to turn both androids into a pile of mechanical junk.

Good point. Although I doubt they'd be able to get such an incredible boost in power in their SSJ1 form unless they break through the SSJ barrier or master the SSJ1 form.
