Talk:Knuckles The Echidna vs. Donkey Kong/@comment-25547865-20141229194201

A feat for DK to help people decide who would win: DK punched the moon to the ground in 1.5 seconds in Donkey Kong Country Returns. Since the distance from the Mushroom World's moon to the Mushroom World is the same as the distance from Earth's moon to Earth, the Mushroom World's moon's mass must be similar to Earth's moon's mass, since the tides are not shown to be significantly different. The mass of the moon is therefore 7.35e22 kg (73.5 quintillion metric tons). The distance to the moon is stated in Paper Mario 2 to be 389,603 kilometers, making the velocity 259,735.3 km/s (or 86.64% of the speed of light). Since that's a relativistic velocity, we must use the relativistic kinetic energy equation to find the energy behind the punch: E=(1/((1-v^2/c^2)^0.5)-1)*mc^2=6.62e39 joules. That's over a fourth of the energy needed to destroy a red dwarf star.
