Can you calculate the radius of a hypothetical singular surface inside a black hole from observing changes to its linear momentum?
Say there is a ball of unknown radius surrounded by a bubble. The ball represents a hypothetical singular surface inside a black hole and the bubble represents the event horizon.
If you threw marbles ...

Is the size of a black hole singularity smaller than a fundamental particle?
I am wondering about the size of a black hole singularity. We know that a classical black hole is infinitely dense. I am not asking about size of event horizon. I am asking about actual size of the ...

Could subatomic particles exist in a black hole singularity?
Hypotheses of black hole singularities imply infinite density because a singularity is a dimensionless point with mass. However, subatomic particles constantly move. In this case, I see no possible ...

Are black hole singularities fermions? [closed]
I was just wondering. I apologize if this is a dumb question. Is it possible that the mass of a black hole is converted into quantum energy that gets distributed across the universe uniformly so that ...

What does M-theory predict at the singularity of a black hole?
how does M-theory avoid problems like infinite density and geodesic incompleteness.
like, is there a fundamental limit to where matter can collapse or simply does matter decay and form a condensate of ...

A Question About the Surface of a Black Hole Singularity
In Kip Thorne's book, Black Holes and Time Warps, he states that the mass of the core of a star shrinks until quantum gravity takes over. And then discusses that at this distance, the singularity ...

Cosmic censorship conjecture: Why naked singularities are expected not to exist?
According to wikipedia, the weak form of the Cosmic Censorship Hypothesis says the following:
Singularities [...] are typically hidden within event horizons, and therefore cannot be observed from the ...

Would naked singularities have the same gravitational properties as black holes of the same mass? [duplicate]
This is just a thought experiment before someone mentions the cosmic censorship conjecture. If physicists are discussing it in papers and scholarship, I wanna see some of those theoretical angles too ...

Does the center of a black hole have a physical body?
From science class, I'm led to belive that all matter breaks down once it's sucked into a black hole. I get that part, but doesn't all that matter still exist in the center of the black hole? yes it's ...

Does a Black-hole Represent a Limit To The Value of Energy-density? [closed]
I've recently read an article that stated the singularity of a black hole could be a string, which is stipulated to be pure energy.
If that's the case, does this mean that the singularity of a black ...

In string theory, what replaces the black hole singularity? [duplicate]
In string theory, what replaces the black hole singularity?
I know that it is possible for a single string to have arbitrarily large energy. Is a black hole just a single string?

Actuality of black hole singularity
With the completion of finite theory of physics, even if the theoretical black hole singularity is completely eliminated, how can we be sure that it does not exist in nature? Physics theory is ...

Black hole singularity in string theory [duplicate]
There is a consensus in theoretical physics that the singularity at the center of a black hole is a mathematical consequence of the fact that general relativity is a classical theory which does not ...

Are the fundamental forces unified in a black hole?
Regarding the question of unification of the forces it is usually presented the following diagram:
So it seems the matter of whether the forces are unified or not relates to how high the energy is.
