### Re: Transmitting Infomation out of Black Hole

What provides this infinite gravitational force? Is there infinite mass in the black hole?? Or I guess a better question would be what provides this gravitational field at the singularity?? Is it a infinite mass to volume ratio?? And if so, I assume some black holes are bigger than others so does th...
