Sure, not really sure who to scale that too though. Guess you could argue Goku's own ki given him calling it to him effectively acts like a vacuum? Guess you can make the case for a minute given how long they speculated Vegeta could last, but the Spirit Bomb only happened after that dried up so *shrugs*
Namekian Dragon Balls also traveled from Namek to Earth in less than 5 minutes, but its only really in the anime you can explicitly tells Freeza reacted to them flying the fuck away IIRC.
Power Pole extending to the moon is something like... let's see, the moon's something like
0.5 degrees? So assuming Goku started by pointing directly at the moon's center, he has until the Earth makes it appear as if the moon shifted in the sky
0.25 degrees to reach before he'd miss the thing. Earth's circumference is about
40,000,000 meters and thus our marker for 360 degrees. 0.25 degrees is thus
27,778 meters or so. Earth rotates at about
460 m/s. Leaves a time frame of about
60.387 seconds? Don't really think where he did this matters, could have been elsewhere than the equator like I'm treating it and the ratios would remain the same I gather
Anyway.
384,400,000 meters to the moon or so. Thus extending at about
6,365,608 m/s or
0.0212C Would also be the absolute lowest end for Roshi and Piccolo's feats respectively ignoring other means of deriving a time frame. Think for Roshi you had debris from the Budokai roof just hitting Krillin's head after the moon was reached and detonated? And Piccolo's still has the fact the debris in the form of dust/smoke is still lingering from Gohan's blast for Piccolo's time frame specifically.
