Singularities/ringularities and their properties

A black hole contains a singularity at its center. It is a zero-dimensional point, and it's where all its mass is located. So, my first question is: If a singularity contains all a black hole's mass,...

Why doesn't a singularity spin infinitely fast?

A question for a random reader passing through: because of the nature of things spinning faster when it gets smaller, wouldn't a singularity spin infinitely fast as it's infinitely small, if it has a ...

How do black hole spinning at speed of light expose its singularity?

Black hole can spin very rapidly something about conserving momentum once a massive star used up its fuel and collapsed under it own weight, if black hole can spin at speed of light it could expose ...

Black hole without singularity?

My question is about the equivalence about having an event horizon and having a singularity. In one side the implication looks pretty obvious: A singularity implies having an event horizon and ...

Does our current understanding of the mass of black hole only allow for it to be located at the singularity? [duplicate]

Does the distribution of mass or density of mass inside the event horizon matter for a black hole to exist as we currently theorize? Could the mass inside the event horizon be distributed in any way ...

Why Did The Universe Expand? [duplicate]

If all of the mass and energy in the universe was in a point smaller than the size of an electron at one time, why did it expand? Did it necessarily expand immediately on formation, or could it have ...

is it possible to prove some version of the “cosmic censorship hypothesis” of Roger Penrose which proposes that this is impossible?

Can singularities not hidden behind an event horizon, known as "naked singularities", arise from realistic initial conditions, or is it possible to prove some version of the "cosmic censorship ...

Are black holes really singularities?

Can't black holes just be super dense objects? They could still be black (having the color of black never really required special physics, after all) and have a really strong gravitational field. If ...
