This is one reason why singularity is a problem. You throw out every 
equation you "do" have about how things work, because, "They don't work 
there.", only.. then you have to ask why, given things like the 
"multiple particles in a Plank Length" issue, which the same math says 
shouldn't happen, even *in* a black hole. If you conclude that, like a 
lot of math, there is a point where it just won't apply, then you only 
have to deal with "one" equation being wrong at that level of mass, not 
***every*** equation in physics, except the one telling you a 
singularity formed. Which seems more absurd, or just less complicated?
