How many dimensions does a singularity have? [duplicate]
my understanding of a singularity is that it is a 'point' in the universe with an infinite energy density. I have also read on the internet that a singularity is one-dimensional.
This is a concept ...

How can two zero-dimensional black hole singularities have different masses? [duplicate]
(This question is not a duplicate because it is primarily concerned with how different zero dimensional objects/singularities with zero volume, are able to contain differing information on black holes ...

What does it mean when people say "Physics break down"?
So I keep hearing people talking about how physics break down at for example the center of a black hole. And maybe I am just to stupid but, why? How can we say that? For all we know a black hole could ...

Why singularity in a black hole, and not just "very dense"?
Why does there have to be a singularity in a black hole, and not just a very dense lump of matter of finite size? If there's any such thing as granularity of space, couldn't the "singularity" be just ...

What is exactly the density of a black hole and how can it be calculated?
How do scientists calculate that density? What data do they have to calculate that?

Intuitively, why do attempts to delay hitting a black hole singularity cause you to reach it faster?
In general relativity, proper time is maximized along geodesics. Inside of a black hole, all future-oriented timelike trajectories end at the singularity. Putting these two facts together, we find ...

What happens if you dump antimatter into a black hole? [duplicate]
Let's say you have a 10 solar mass BH and dump 10 solar masses of antimatter into the BH... What would happen?
Would I have a 20 solar mass BH?
Would the BH explode
Do we even understand what would ...

What is the physical size of a black hole?
Something that's always confused me. How large is a black hole's physical size - not mass?
From descriptions, it would seem that the 'singularity' is a single point, but is it really?
Say for ...

How massive objects affect distance measurements, or "But how far away is a black hole singularity, really?"
My question basically boils down to: Is the singularity of a black hole infinitely far away?
I think questions like mine have been asked before, but they encounter responses like "no meaningful ...

What's the proper distance from the event horizon to the singularity?
How far away is the event horizon of a (Schwarzschild) black hole away from the central singularity for a radially infalling observer starting with $v=0$ somewhere outside the black hole? After ...

Entering a black hole, does the incident angle matter at all?
Inside the black hole (as you enter the EH), all objects (massive or massless) must move towards the singularity. The singularity becomes a moment in future.
In the context of general relativity, ...

Is it possible the space-time manifold itself could stop at a black hole's event horizon?
This is a repost of a question I saw here:
Could the spacetime manifold itself end at the event horizon?
which was closed because it apparently didn't seem clear as to what the poster there was ...

Topologically, is a curvature singularity just a hole?
Topologically speaking, a hole can be introduced into a manifold and it will still be a manifold, e.g. remove points within a 2-sphere of some radius from the cartesian plane and you'll still have a ...

If a Black Hole Singularity is a 1 Dimensional Object, How Does it Affect 4 Dimensional Space
If the center of a black hole is an one-dimensional point, gravitational singularity, where density and gravity become infinite and space-time curves infinitely, then / why:
If spacetime is warped ...
