The feat[]
In MURDER DRONES - Episode 6: Dead end, at the 10:45 - 10:50 mark, it's revealed that Cyn used a Black Hole in order to destroy the Earth.
Figuring out the size of Black Hole[]
Our reference[]
We can use the Moon as our reference, as shown here.
How do we know it's the Moon and not Mercury or Venus? Because the Moon is the only thing that would look that big at that distance, if it were Mercury or Venus, it would've been invisible due to being so far away from Earth.
Finding the size of the Black Hole[]
I'll be using two ends for this.
Low-end: Assuming the Black Hole itself is only the black part in the middle.
High-end: Assuming the Black Hole is the entirety of the sphere.
The Moon is 80 pixels wide (Green), the Low-end Diameter of the Black hole is 65 pixels wide (Blue), the High-end Diameter of the Black Hole is 138 pixels wide (Pink)
The Moon's diameter is 3,475 km
1 pixel = 43.4375 km
Low-end Diameter: 43.4375 x 65 = 2,823.4375 km
Low-end Radius: 2823.4375 / 2 = 1,411.71875 km
High-end Diameter: 43.4375 x 138 = 5,994.375 km
High-end Radius: 5994.375 / 2 = 2,997.1875 km
Finding the AP of the Black Hole[]
Using the chart provided here, we can find the AP of the Black Hole
Low-end AP: 1,411.71875 km = 1,411,718.75 m (Large Star Level)
High-end AP: 2,997.1875 km = 2,997,187.5 m (Large Star Level)
