How is it possible that black holes at radius zero, have infinite density?
How can black holes be infinitesimally small, therefore having infinite density? It would make more sense for a black hole to be incredibly dense.
What is the size of a black hole? How small can a black hole be? If the curvature of a singularity of a black hole is infinite, would this suggest that it is spherical? How strong is a black hole the size of an atom? What is the diameter of black holes? What is the diameter of black hole? What was the size of the biggest black hole? Why didn't the universe just develop into a super massive black hole if in the beginning it was very dense with matter and energy? What is the size (or range of sizes) of a black hole? Can a black hole be compressed? How powerful is a black hole? Why are extra dimensions (11) required for string theory to explain black holes? What is beyond a black hole? Would the singularity in a black hole affect dark matter? If so, in what way? If the universe is in a singularity, how would you explain the fact that the universe has scale? Could dark matter be regular matter but with 1 change, it is 4 dimensional (spacial dimensions)? What is a black hole singularity? Are there an estimates for the amount of dark matter a black hole contains? Is what is thought to be the density of the dark matter actually the state of displacement of the dark matter? What is a black hole? What is a black hole? What does "infinite mass" mean? What is the biggest black hole we know? Does dark matter affect black holes? Can a black hole be created inside a black hole? Wouldn't the event horizon of a black hole be a sphere around the central mass? What is the shape of a black hole? Is there any observable difference between a non-point mass with radius less than its Schwarzschild radius and a black hole? Can this mass exist? What is called a black hole? Could the singularity of a black hole be a graviton?
