Calculation[]
As we see, Bowser's half of head is 230px, while the blocks are 66px
These blocks are about Mario's height
Mario is 5'11, or 1.803m, or about 180.3cm
180.3/66: 2.73181818cm per pixel
Bowser's head is 230px, so...
230*2.73181818 = 628.318181cm
248/68 = 3.64705882
Now...
628.318181 * 3.64705882: 2291.51336m
Now, the black hole height....
494/6 = 82.3333333
Black hole is 82.3333333 times Bowser's size, so...
2291.51336 * 82.3333333 = 188667.933 m, or a 94333.9665 meter radius.
- Speed of light: 299792458 m/s
- Gravitational constant: 6.67e-11
(94333.9665)*((94333.9665)^2)/(6.67e-11) = 1.25857312e25 kg, or 6.32734966e-6 solar masses.
6.87e41*6.32734966e-6 = 4.34688922e36 joules, or 1.03 Ninatons. Large Planet level.
