Black holes kinda break people's brains. The Schwarzchild radius black hole that was sucking in cars and bridges was about the size of a football field as depicted in the game.
I did the math. Such a black hole would have to be 17 solar masses.
A black hole that massive would not just suck in a bridge or two. Earth would basically cease to have an independent gravitational field at that point. There would be no planet anymore, and it would be gone in a hurry. π
