@SMXLR8: I figured that much ¬_¬ I was going to start a private conversation, but we may as well do it here.
You may have heard this argument before, but I believe it is the best example of DBZ characters being FTL, and that is the incident with Piccolo blowing up the moon. Without having to charge up, Piccolo fired off a beam that reached the moon in the space of a few seconds.
Now the usual response to this would be "but that was anime only, we don't know how long it took to reach the moon in the manga."
I don't mean to insult your intelligence with this or anything, but just to remind ourselves of the ground facts.
The speed of light is 299,792,458 m/s. The distance between the moon and the earth is generally held to be 384,400km (384,400,000m).
Now let's consider the scans to refresh our memory:
We notice that Piccolo is in the exact same position when he fires the blast and when the moon is gone. This strongly suggests that very little time has passed at all. What reinforces this case is that Gohan (as an Oozaru) was firing off energy blasts everywhere. It is therefore ludicrous, having noted these points, to say that the beam could have taken much time at all to reach the moon. Piccolo could not have remained stationary whilst in danger of getting hit by an oozaru blast, nor would he have just sat there in the exact same pose.
So, getting to the numbers, being harsh on DBZ, let's say no more than 10 seconds could have passed (IMO it would have been less, more like 5, but I'll be lenient).
384,400,000m/10s gives a speed of 38,440,000m/s. That means Piccolo's blast was moving at over an eighth the speed of light if we go by this, putting it firmly in relativistic territory. This was a Piccolo with a PL of less than 500.
Nappa was outmaching a stronger, faster Piccolo. Nappa was pretty much blitzed by Goku's kaio-ken x 2, yet Vegeta was easily able to keep up with it. Burter was faster than an even stronger Vegeta, yet was totally outmatched by Goku with a PL of 90,000. By the time we get to Freiza's death beam in his final form it would be reasonable to say that they are FTL.
Let me know your thoughts on this.
