Again that was incorrect. The speed used in Kirby's calcuation used the speed of the attack and NOT the gravitational escape velocity of the moon itself. That should equal the gravitational binding force of the moon. Since we don't know what that is, the person who calculated that amount OVER-ESTIMATED it by using the wrong figure. He was practically guessing.

And again, if the force was in Zettatons, the planet next to the Moon should be dead too.

I saw the calculation for Vegeta's destruction and it makes the ASSUMPTION that Planet Vegita has the SAME DENSITY as Earth, yet is over 4x the size of Earth and ten times the mass (assuming from ten times gravity). Again that's incorrect. Jupiter is over 11x the size of Earth and 317x the mass, yet its gravity is only 2.5x. If you plug in those incorrect numbers into the normal formula for gravitional acceleration, you WON'T get 10 times Earth's gravity, which is about 98 m/s.

Unfortunately, Akira Toriyama was no science whiz and wrote stuff that didn't follow normal science, such as twirling Goku's tail like a helicopter, having the planet self-destruct after its core was destroyed, or having NO ENVIRONMENTAL DISASTERS happen after destroying the Moon... twice.
