What would be the Schwarzschild radius of an $n$-dimensional black hole? [duplicate]

The Schwarzschild radius of a 3 spatial dimensional black hole is 2GM/c^2. What would be the Schwarzschild radius of an n dimensional black hole according to Einstein's field equations having n x n ...

Could we use experimental evidence of micro black holes to prove the existence of additional spatial dimensions?

They are planning to create a new particle accelerator that can smash particles together at a much higher energy than the LHC. If in the process we observe the decay of a micro black hole, would that ...

Massless Tachyon in 2D

Referring to a large number of works on 2D bosonic string theory with particular attention on the worldsheet description of 2D black hole solution (cigar CFT) I don't understand why the tachyonic ...

Should black holes be considered two-dimensional or three-dimensional?

Should a black hole be considered two-dimensional or three-dimensional? It means that a black hole doesn't occupy space, but interacts with it. Or it actually occupies space, and still interacts with ...

Wouldn't micro black holes in the atmosphere have noticeable effects?

If there are extra dimensions of space,the force of gravity would (in microscopic distances) increase way more than a factor of 4 times when the distance between masses is halved,which is the case in ...

Do new gravitational effects emerge in higher dimensions?

Effects like gravitational waves and the curvature surrounding black holes do not occur in spacetimes with one time-like coordinate and two space-like coordinates. This is because the Einstein Field ...

Black hole's singularity: Does it has to be multi-dimensional? [closed]

We assume that there is an infinite density at the center of a black hole. But we also know that if it was really infinite, it would apply an infinite gravitational force to masses even if they were ...

How does a black hole's gravity affect other dimensions? [closed]

Given the extreme gravitational force of a black hole, can it have affects on other higher dimensions? Does it continue to warp space-time regardless of the number of dimensions? In fact, can a ...

A two-dimensional event horizon?

Today, I came across an article which says that the Universe began with the collapse of a 4-dimensional [spatial] Universe. Well, I don't know if there's any way to confirm these like it is with all ...

Behavior of black holes in higher- and lower-dimensional space-times

The behavior of black holes in 3+1 dimensional space-time as our own is rather well known: formation, event-horizon size, mass, spin, radiation etc. However, my question is what would black holes ...

$2+1$ dimensional physics theory of our universe?

Is there any physics theory that depicts our universe as $2+1$ dimensional? I heard that black holes seem to suggest that the world might be $2+1$ dimensional, so I am curious whether such theory ...
