The event horizon of the black hole in the cartoon appears to be roughly an inch across, which using the formula linking Schwarzschild radius to mass (r = 2MG/c^2) gives a black hole of about 3 earth masses.

− | :OMG. That would mean it also excerts 3 times the gravitational force of earth. As a result people near (also as far away as earth orbits) would only be comfortable standing at a significant angle | + | :OMG.

:That strong a pull would mean the hole would not only collect air and particles, but also pull furniture into it. Seing as both people are standing upright I'm guessing the pull can not be more than say one fifth of earths. Maybe it has a visible accretion disc? If you were to run the formula in reverse what diameter would that give you of the hole itself?
