Hm. Is there anything we could do to improve the celestial bureaucracy? Getting Yemma in our favor would be really good.
The generally dysfunctional nature of the celestial bureaucracy seems to be one of the fundamental underlying principles of the cosmos in Dragonball, so I'm guessing it won't be easy.
Well, maybe a bit late, but I'm not sure there even is FTL travel in DBZ, for one simple reasdon: I suspect there isn't actually a lightspeed limit.
In real life, anything that travels faster than light is timetraveling; "the present" propegates at a light cone. When you look at the stars in the sky, you are still seeing part of the present. In DBZ, timetravel is a huge deal, but nothing is done about all of the extremely fast ships, or Goku's instant transmission, or the freeza force's communicators, or intergalactic ki sensing, etc. even though in real life these would all be time machines.
Well, the root cause for this is that anything traveling faster than light is time travel
in some hypothetical frame of reference. Like, if you travel FTL at 100 times the speed of light from Earth to Mars, nobody on Earth or Mars actually thinks you traveled backwards in time... but a passing spacecraft moving at relativistic speeds in certain directions might think so.
The prohibition on FTL travel is a consequence of "causality must hold in all frames of reference," which means no thing that could EVER appear to be time travel is allowed to happen.
...
The most likely explanation is that in Dragonball, there is a privileged frame of reference for the universe within which the question "so, is this or is this not time travel" is arbitrated. Say, in terms of "parameters of your movement relative to the Sacred World of the Kais." As long as an observer standing on the surface of that planet doesn't think you're time-traveling, you're not time-traveling, so it's all good. Or something like that.
And yes, general relativity is not REMOTELY salvageable in this context. It goes right out the window, which means that yes, gravity manipulation, spatial distortion, and time travel CAN operate on fundamentally different and unrelated sets of physical laws.
On the other hand, they could also still be interrelated but in a different way, and it WOULD help explain why one father-daughter pair of scientists could achieve so many great things if all those things tapped into the same core set of fundamental knowledge.
my maybe is not about training them, more about making them an explicit part of the style (and receiving the related bonus to rolls.). That would require modifying the style, wouldn't it? Unless they don't count as techniques for the rolls but directly apply to the power level instead.
From the sound of it, they apply only to power level.
It's like, the only style for which Kaio-Ken is an 'involved technique' is Goku Style, which I suspect means that Goku stylists get bonuses on Kaio-Ken rolls, NOT that you have to be using the Kaio-Ken to be fighting in Goku Style or that you have to be a Goku Stylist to use the Kaio-Ken while fighting.
EDIT: the idea of a Kaioken overloaded hypercompressed ki boost (mixing all 3 ways we know to make us stronger than normal) IS appealing though.
I'm not sure we'll be able to combine all three methods, and I suspect that using Overcharge and the Kaio-Ken at the same time might have nasty side effects. We know that Jaffur's Ki Refinement and the Kaio-Ken are compatible, though, because we've seen him use both at once.
