What has a higher density? Black Holes or Singularities?
I looked online and all I saw was that they both have infinite densities.

As I said in the previous post the "size of a black hole" is generally taken to be the diameter of its event horizon. The actual geometry of the black hole is pretty involved - but as a simplification, imagine that all of the mass of the black hole is concentrated in a singularity, a point, at the center. The size of the event horizon is the sphere around that point where light cannot escape. If you double the mass at the center, the distance to the event horizon increases so the total volume of the black hole increases. That total volume will more than double. So, heavier black holes are less dense because they can enclose more empty space.Hoophy said:I heard that a black hole can have a extremely low density. Also I heard that the bigger the black hole the lower the density. This does not make much sense to me, is it true? And if so can someone explain why?
A singularity is a point in space where the laws of physics break down and become infinite, while a black hole is an object with a singularity at its center, surrounded by an event horizon that marks the point of no return for any matter or light that enters it. Essentially, a black hole is a region of space that contains a singularity.
No, a singularity cannot exist without a black hole. Singularity refers to the point of infinite density and gravity at the center of a black hole, so the two are inherently linked.
At the singularity, the laws of physics as we know them break down and become unpredictable. The gravitational pull is so strong that it warps space and time, and all matter is crushed into an infinitely small point.
No, they are not the same. The Big Bang singularity refers to the initial point of the universe, while the singularity of a black hole is the result of a collapsed star.
No, the singularity of a black hole cannot be observed or studied directly. The event horizon of a black hole prevents any information from escaping, so we can only study the effects of a black hole on its surroundings.
