In Dragonball Z, I rarely see a mechanical device, mostly just electronic. And the first fight between Goku and Vegitta should have ended the stability of Earth orbit (and hence everyone Goku trying to save.) So just change Newton's Law of motion assumptions, theorically is still possible to have life. What ya think?

In the series, "Captain Harlock," someone point out that the Japanese's animator have flag flying in space. This is plausible since it is time that affected motion so "rocket-science" is not really rocket-science. Also one must consider language, look, culture, symbol,... It just a message and something to relate to but not sure if it look exactly the way it look. Japanese, Korean, some Chinese (specially ancient Chinese 'yeeeeah!!!!'),... tend to keep theirs words, so the preceptions should be as close as it get.

before you question the ability of the earth to sustain orbit... question the ability for a huge ball of energy to materialize infront of goku's hands when he cusps them together

Wind there is differ than here if it exist. By theory, it exist due to the advancement of mathematical tools and physical realisation. For example, there can be more than 4 seasons,... Anyway, a person with a strong charimas can do Thai Chi something if that what you're trying to get across. Whatever. Charimas does not belong to anybody from what I conceived so far.--shug What's next, Cocobot's Mountain cut. I already figure out how to build up chraka (accumulation of flesh sins against the person concerned) to cast Radien's light and Thor's thunder by word request. Make sense now my "friend," refering to my former Charter school student for this accumulation of "chraka."

^ you dont even spell CHAKRA properly




dragon ball, is off science,
and should be keep it that way.

or else DB movie or people like to assosiate everything with science exist

DBZ isn't plausible to real life...really?

Maybe...just maybe...if you think about, that's why people use animation?
