Can the characters exceed the speed of light?
I asked a similar question on alt.fan.dragonball a few weeks ago, but I didn't like having to wait two days for new posts to appear on Google Groups, so I thought I'd ask it again here.
We know that "Chibi" Trunks in his normal form can't accelerate to anything even approaching relativistic velocities within a reasonable time frame because he had difficulty moving in 150 g. His inability to move freely in that gravity would limit his acceleration in his normal form to less than 1450 m/s^2.
People have referenced Radditz's ability to dodge Piccolo's "Makankosappo"(sp?) early in the series as evidence of superluminal capabilities in DBZ, but that would give Radditz outrageously high accelerative abilities somewhere in the neighborhood of 2.997e8 m/s^2, so I don't really consider that convincing evidence.
I would personally say that the characters usually maintain a velocity slightly slower than the speed of sound.

I never quite agreed with Jim's notion that Makankousappou = light, but...
Actually, any mention of light speed always reminds me of a very stupid error of mine, but looking back on that, I'm reminded of my argument about flight speed not being physical movement, and thus wouldn't be reliant on the body's speed.
Science and physics are not exactly a strong point of mine, but now, light speed seems a bit much even for Dragon Ball, just from a common sense standpoint. Even if the strongest few people near the end were capable of attaining that speed, I have to doubt that they would've had the power to maintain it.

That's not debateable, you are completely right there, however, the normal laws used for their Gravity and Light are not used there, as it is fiction and the universe is lead and bound by the story. Physics and whatnot is subject to that, thus all contradictions and errors are null and void. Also, it doesn't have to explain itself.
Zanzoken is "proof" that they're moving faster than speed since it leaves an after image on the viewers retina.however, the normal laws used for their Gravity and Light are not used there, as it is fiction and the universe is lead and bound by the story.

One thing that confuses me is, if they're not moving as fast as people think, then why is it that except for trained warriors can no one see their movements?
And even then, remember when Goku was fighting Freeza, after a while, their speed increased so much, that even Kaio-sama couldn't follow them.

It only takes about 30 m/s^2 of acceleration to be too fast for the human eye to perceive.Jerseymilk wrote:One thing that confuses me is, if they're not moving as fast as people think, then why is it that except for trained warriors can no one see their movements?

EDIT: If training was able to improve their ability to see someone accelerating that quickly, it was probably connected to their ability to sense "ki" rather than direct visual perception.

I don't think they go that fast. Not speed of light fast anyways.
But whatever, right? It's Toriyama land not <insert some scientist's name that knows about physics and stuff> land.
But the point about them not being able to see the movements I think has a lot to do with the nature of the movements. They move everywhere in a very erratic no-pattern sorta way during battle (a lot harder for the eye to follow than a line in the sky) unlike say a fast jet which obviously doesn't know zanoken. Anyways...

That still doesn't make sense though. People don't "blur" as they move. Sure, there's a delay between something happening and a person seeing it, but the after-image left by the Zanzoken hangs around for several seconds. For that to make sense, a person would have to be standing several light-seconds away from the person they are fighting. If the after image was visible for 3 seconds, then the fighters would have to be 900,000 kilometres apart.Dayspring wrote:Zanzoken is "proof" that they're moving faster than speed since it leaves an after image on the viewers retina.
So, obviously, no.
