Mass-energy Conversion Feats - Energy Constructs
Note: Source for mass of all life forms on Earth
I assume there are 100*10^9 planets that has a similar mass of life forms on Earth, and 300*10^9 such galaxies in the universe.
1. Some novice magician created a longsword as an energy construct and is accepted as a mass-energy conversion feat.
Energy used = 1.25824E+17 (City level)
2. Some crazy magician snapped and created a solar system complete with 1 sun and 8 to 9 planets.
Energy used = 1.78962E+47 J (Solar System level)
3. Some crazy cosmic tyrant snapped and decimated half of all life forms away into energy from the universe.
Energy used = 50% * 2.7457E+52 J = 1.37285E+52 J = (Solar System level)
Turning an average building to ashes
Wikipedia states that the average size of an owned residence in Japan is 121.7 m^2. When you think "average house/ building" you have in mind a two-storey building, which is approx 6.6 m.
This site gives us a volume of 859.1 m^3. Density of concrete is 2400 kg per cubic meter. So 2,061,840 kg = 2,061,840,000 g.
Using the formula Q = m*c*ΔΤ
Using 3 ends of 80%, 85% and 90% hollowness for the mass.
According to Assaltwaffle, concrete's specific heat capacity is 880 J/kg°C.
Change in temperature is from room temperature to concrete's melting point:
Concrete's melting point = 1450 °C (google source)
Room temperature = 20 °C (average of 15 °C and 25 °C)
High end: 80% hollowness: 2,061,840,000 x 0.2 x 880 x (1450 - 20) = 5.189e14 J = 124 kilotons. Large…
Cannonball AP
Using the standardized values, a cannonball weights 32 lb (14.514 kg) and has a speed in between 1250 feet per second (381 ms), 1450 (441.96 ms) and 1700 (518,16).
Simple enough.
I'll do 3 ends.
Throwing it into the KE calculator.
14.514 kg and 381 meters per second=1053430 joules
14.514 kg and 441.96 meters per second=1417500 joules
14.514 kg and 518.16 meters per second=1948430 joules
All high end Wall level
Low-end=1.05 megajoules, 9-B
Mid-end=1.41 megajoules, 9-B
High-end=1.94 megajoules, 9-B
The correct end would end up being case by case, depending on the cannon.
Keep in mind it can also be much higher (9-A) or much lower than this, it all depends on the cannon. This is just an baseline.
General Calc: Vaporizing Earth
- 1 Premise
- 2 Calc
- 2.1 Mass of Elements
- 2.2 Specific Heat Energy
- 2.3 Shifts in Matter
- 2.4 Total Energy
- 3 Tallies
Not sure if we have a calc for this and this will be relatively rough, but let's try. I should note that this calc does not account for other factors of dispersing the Earth into vapor- the pressure, GBE, etc. We are purely looking at the energy needed to reduce the base elements to gaseous form.
Based on this we're looking at the most prevalent elements in the Earth. All of this comprises the mass of the Earth (5.98e24 kg).
Iron: 32.1% (1.91958e24 kg), Heat Capacity of 460
Oxygen: 30.1% (1.79998e24 kg), Heat Capacity of 919
Silicon: 15.1% (9.0298e23 kg), Heat Capacity of 710
Magnesium: 13.9% (8.3122e23 kg), Heat Capacity of 1050
Sulfur: 2.9% (1.734…
Batman survives an intersection exploding
Oooooookay, so I finally fixed it.
Re-do of the first calc in this blog.
Turns out the crater has a determined width and depth we can find out using the taxi in the crater.
Also I think I might be able to correctly guess how far Batman was away from the bombs basing on where he was standing next to the dogs.

- 1 Heights and surface area
- 2 Pixel-Scaling and volume
- 2.1 Pixel-scaling part 1
- 2.2 Pixel-scaling part 2
- 2.3 Volume
- 3 Calc
- 4 Values
Since this makes of inverse square law, I'll use Bats' height and weight for surface area with this calculator.
Batman is 6ft 2inch and he just so happens to be 210 lbs. Slap those in the calculator and we get 2.2 m^2. Divide by two and its 1.1 m^2.
