Planet Busters

[Nex Carnifex]

I think you made a math error in there somewhere, and I'm going to wager that you forgot to take the difference in exponents. Bussani actually made some calculations of his own at the top of the second page and they seem like a more accurate estimate, albeit I haven't actually done the math for myself.

Yes, it seems I did miscalculate the difference between the exponents. I don't really understand how I made such an error. But I can guarantee you that the gravitational binding energy of both the Earth and Moon are correct. After re-working this out then the Moon is 0.000555307760927743086529884032% of the Earth. By dividing 140 by the previous percentage it gives us 252,112. Or you can additionally work out how much you need to multiply the Moon's gravitational binding energy to get the same amount as the Earth's by dividing the Earth's binding energy from the Moon's which gives you 1,800.8032128514056224899598393574. Then just multiply 140 by that and you should arrive at the 252,112. Of course this means that there is no way Freeza could have destroyed Planet Vegeta with a powerlevel of 530,000. Unless his death ball, or whatever technique he used to destroy Planet Vegeta increased his ki output several times as Planet Vegeta has a much larger gravity than Earths, even if it was the same size the gravitational constant would probably have to be re-thought.

Rocketman pointed out once that the curvature of the Dragon Ball world's moon would mean that it's much smaller than our moon, and would thusly have to be closer to the planet to appear so large in the night sky. There was a bit of a discussion on it a while back you can find here.

The problem with this is it was a gag panel, I don't think we should take this into account when considering the size of the moon. Sure Akira brings up the point in one of the Q&A's in the tankoubon that Goku did indeed put them on the moon but I think he used it purely to say that the Nyoi-bo could stretch up to at least 380,000 km, considering he says it can go up to at least 380,000 km and the average distance between the Earth and the Moon is 384,400 km then I would say that it was indeed the same size as our Moon. Hell, we can't expect Akira to draw everything perfect. He isn't a god who can just slap out anything onto a paper and it be in perfect proportion.

Then why was Roshi surprised he blew up a mountain if he can blow up something trillions of times larger? I think it makes sense to say its at least like half the size of ours, but its not like its a big deal all we have to go by is a cartoony gag panel.

I don't think the surprise was because he managed to blow up a mountain. He says in the manga "Looks like I don't know my own strength." he was probably holding back when he blew up that mountain and was surprised that he could do it even though he was holding back. If the moon was half the size of ours and Kame-sennin was using his maximum power then there would be more than a mountain missing even with the moon being half the size of ours. Also, as I recall, Kame-sennin just called it a regular Kamehameha when he fired it at the mountain. At the Tenkaichi Budokai he said "Kamehameha! Maximum Power!" so that was the maximum output he could fire as opposed to when he shot at the mountain. If you also take a look at the panels side by side you will notice that the Kamehameha he fired off at the Tenkaichi Budokai was much larger than the one he used on the mountain.

Yeah it was a stronger attack but Piccolo Daimao's strongest attack only seem to wipe out a large city. I think it's just another inconsistency in the series.

The size of a destroyed area shouldn't be a a factor of how much Daimao Piccolo could destroy. If we fast forward to Majin Vegeta, who is a million times stronger than Daimao Piccolo his final attack against Buu with all of his energy was contained to a small area as he would have probably killed everyone on Earth if he didn't contain it. Daimao Piccolo may be evil but he doesn't want to wipe out a lot of people because he's really a tyrant. If you think back to when his youth was restored he said he would destroy a city every year. If he wanted to kill everyone he could have probably done it in less than a year.

Majin Vegeta's attack is likely smaller due to ki control and I remember that ki control was never shown or used until Nappa and Vegeta arrived at Earth. I doubt early DB characters have ki control.

[Bussani]

How do you define "ki control" in this case?

[Hitiro]

Majin Vegeta's attack is likely smaller due to ki control and I remember that ki control was never shown or used until Nappa and Vegeta arrived at Earth. I doubt early DB characters have ki control.

Actually ki control or manipulation(As to control would mean to manipulate ones ki) forms the basis of all attacks, we see ki manipulation throughout the series, even in dragonball. Ki manipulation includes things like controlling the movement of a ki attack or even copying other peoples techniques, even performing ki techniques requires ki control. A prime example of ki manipulation is when Goku and Krillin bending their beams to strike their opponents from behind or to follow them. And Tien, probably the best best human ki manipulator next to Krillin and Kame-sennin, has shown an amazing ability to grasp other ki based techniques. This is because he is very proficient in ki manipulation. If they can change the direction of their own ki blasts and pick up on ki techniques pretty easily then they can regulate the destructive area of one of their ki attacks. Considering the wide range of Daimao Piccolo and Piccolo Jr's abilities they are by far the best ki manipulators until the Saiyan arc. If the dragonball characters couldn't perform any ki control they wouldn't be able to use any ki techniques.
