The DK = star-buster claim requires that the Mario universe's moon works like the real moon, which it apparently does not.

1. The distance from the Earth to the Moon, from Paper Mario, is not applicable to the continuity of the rest of the Mario-verse. This should be obvious by the fact that one of the moons is made of paper and the other is not. See a few lines below for a better estimate.

2. The moon accelerated before it hit the island (look at the first few frames of the moon's fall), explicable better by the force of cartoon gravity. If anything, this only suggests that DK canceled the Moon's orbital kinetic energy. This is on the order of 10^28 joules for the Earth's moon, not 10^39 joules.

3. When the moon bounced back up, its orbital position becomes obvious with respect to its size. It looks to orbit at a height very close to 7.5 times its diameter above the Earth, measuring from the center of the moon. this approximation is enough for order-of-magnitude calculations. It's hard to tell what the Moon's radius is, but in reality, it's 1.079.6 mi. So the moon dropped a distance more like 7*1.079.6 mi = 7557.2 mi, not hundreds of thousands of miles.

4. What in the world was with the long delay of momentum transfer?

5. The moon was light enough to balance on the island's volcano, and the volcano's eruption put it back in orbit. It should be obvious that the volcano was not even a planet-buster, since the planet it rested on was intact. Even for a supermassive kill-the-dinosaurs-type volcano releasing 1,000 km^3 of rock at escape velocity, that's only about 1,000 km^3 * (,2500 kg/m^3) * (11.2 km/s)^2 = 3.136 * 10^18 joules, not 10^39 joules.

These all result in wildly different answers and changes to the calculations, which just goes to show that calculations based on real-world physics is just not the way to measure that feat.

It should also be noted that you're using this feat to prop up Luigi, when it does not follow that Luigi can bust stars even if DK can, just because they sparred.
