The Size of Planet Earth

[nickzambuto]

Damn I'm getting tag-teamed.

Seems a science lesson is in order...

In a circle like object, say the Earth in this case, the Radius is the measurement from the circle's center to it's outermost ring.

Diameter, is the measurement from one side of the circle to the other, straight through.

Circumference, is the measurement of the outermost ring itself.

So if the Earth's Radius is 6,000 Km. then that means that if you went straight through the planet from one side to the other, you would have to dig 12,000 Km. straight through. I recommend taking more than a few ice packs with you though.

And about planetary size. According to Toriyama, Dragon Ball's moon is the same distance from it's Earth as the real one is. This means that Earth is also the same size. Why? Because the more mass something has, the greater it's gravitational pull. If the planet was smaller, the moon would float away. If it was larger, the moon would be pulled towards it and crash into it.

The moon's size wouldn't have as much to do with Earth's gravitational effect on it, as it's fairly small in comparison to the Earth. It would have SOME effect but not really enough to matter. It's more about distance from a gravitational source than it is size, which Toriyama himself said is the same. As such, unless gravity works differently in Dragon Ball, we can assume that both Earth and the Moon are the same size.

Keep in mind that I'm not trying to say that DB earth is smaller or larger or whatever than real world Earth
To clarify:
- Roshi's island was 10k km away from their current location
- nickzambuto implied that it could mean that DB Earth was actually larger than our earth based on radius alone even though the distance from Roshi's island to Freeza's landing point was more likely than not based on arc length instead of chord length since the earth is still round, and people don't quite travel in through one side of the planet and out the other yet.
- I therefore challenged that thinking, saying that given the actual distance that it could take to travel from one spot on earth to another through, say, flying around over earth's surface meant that wasn't necessarily the case.
The bulk of the evidence supports the belief that the volume, mass, gravity, etc. is pretty much the same with our Earth and its Moon as Dragon Ball's Earth and Moon anyways.

Guess I wasn't specific. That post wasn't really aimed at you. I simply added your post into it because you actually knew what you were talking about, whereas nickzambuto, who the post IS aimed at, didn't seem to.

Yeah i thought that you responded to my reply because it looked like i might have been trying to downplay db lol

Nope. I just wanted to make sure that he and everyone else knew what those measurements actually meant. Not everyone remembers everything they learn in school and I imagine some users haven't made it that far in school yet.
