You are riding in a motorboat. The feeble motor is capable of only 10 miles per hour. At a certain distance from a whirlpool, your weak engine can keep you exactly between the swirling vortex and a tree on the shore. You want to see the whirlpool better, so you creep closer. Beyond a certain point, the circular current is moving faster than 10 miles per hour. It is now impossible to remain between the vortex and the tree on the shore. You turn your boat away from the whirlpool and return to where you started.
A is the description, in real-life terms, of the static limit of a
rotating black hole. Within the Static Limit, the torsional effect of
the rotating black hole is great
enough that light itself cannot move fast enough to remain between the
black hole's center and a distant star (the aforementioned tree on the shore).
B is the description of the Event Horizon of a black hole. Once within
the Event Horizon, the pull toward the center is so great, not even light
And the center? No one knows what will happen at the center, or the
singularity. Density is infinite. Time is effectively meaningless.
The laws of reality break down.
