Do black holes have infinite density?
How is it possible that black holes at radius zero, have infinite density?
If the curvature of a singularity of a black hole is infinite, would this suggest that it is spherical? What is the size of a black hole? How small can a black hole be? What is the diameter of black holes? How strong is a black hole the size of an atom? What is the diameter of black hole? Are there an estimates for the amount of dark matter a black hole contains? Would the singularity in a black hole affect dark matter? If so, in what way? 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 the size (or range of sizes) of a black hole? What is beyond a black hole? Is it possible to have the event horizon of a black hole without a singularity? Is there a singularity inside the event horizon of a black hole? What is a black hole singularity? How powerful is a black hole? Wouldn't the event horizon of a black hole be a sphere around the central mass? What was the size of the biggest black hole? Do all galaxies have a black hole? Could the singularity of a black hole be a graviton? Is it possible to create artificial singularity(black holes)? What is the radius of the black hole at the center of our galaxy? If you could reach the black hole center, would you just see a tiny black orb? Can a black hole be compressed? Could dark matter be regular matter but with 1 change, it is 4 dimensional (spacial dimensions)? Can another black hole exist in a black hole? If sound waves have no mass, can they pass through black holes? If the universe is in a singularity, how would you explain the fact that the universe has scale? Are black holes and singularities related? Could the universe be inside a black hole? What is the shape of a black hole?
