The quick answer is that you need the Death Star laser.

[vh]

yes well i was wondering how much energy the laser would have to consume.

[smjjames]

I think people have already done the math, just google about the Death Star Laser.

[vh]

yes, thats where i got the formula. Anyway, a laser is doubtfully 100% effeicient for planet destruction.

and i want to be able to calculate how to destroy any given body

calculated: 640 billion joules (25% world consumption) of energy to blow up the world of blacraft assuming a 9 km^2 surface and that below bedrock and under is all solid.

it's take 0.6 picojoules to blow up a human being held together with only gravity.

it's take 0.6 picojoules to blow up a human being hamster (as in the darvince's sister) held together with only gravity.

2.80E+46 joules to blow up an average neutronstar

in other words, the amount of energy a 500 sun-sized stars would emit in it's lifetime

[vh]

22 years worth of all the energy emmited in the form of light from all the stars in the milky way to blow up a neutronstar

Borderguard makes Blacraft 36 km², as it is 3 km in every direction (thus 6 by 6 km).

Cool though, now calculate how many TNT blocks that is, and how many chests we will need to store them, and how many chests we would need to store the chests to store them, and the amount of wood we would need to make the chests, the amount of time it would take to gather the wood with fists, and how much wood we would need to make wooden axes for gathering the wood, and how many chests it would take to store the wooden axes, and the amount of wood we would need to gather to make the chests to store the wooden axes, and.....
Nvm.

^And calculate the energy of a TNT block in minecraft

I considered that implicit in calculating the TNT required to blow up Blacraft, but yes.

I calculate that it would take over 50 billion megatons of TNT equivalent to blow up the Earth (assuming 100% efficiency).

The global nuclear arsenal is supposed to be about 5000 megatons. Even assuming that there are a whole bunch of secret bombs which would raise the arsenal to 10,000 MT, we don't even have anywhere near a millionth of the energy required to blow up the world.

Equivalently, assuming 50% efficiency (the maximum given that 50% of the energy from proton-antiproton annhilation is lost as neutrinos), it would take 5 million tons of antimatter to blow up the Earth.

Alternately, you could just do this: Falcon Punch

plugging in 36 km surface area gets me at 920 megajoules. Assuming 50% of the energy goes into physical energy, it'd take me 1840 megajoules worth of explosives. 1 block of tnt irl is worth 500 megajoules, so you'd only need 3 blocks. However, in minecraft it seems different. Even a tiny stick of tnt can blow up a whole wall irl. So minecraft tnt, my rough estimates, is 5,000 times weaker. We'd need 15,000 blocks of minecraft tnt, or about a 25 x 25 x 25 cube of tnt to blow up blacraft
