0 = ∞ x M

So singularities have no mass, therefore no density, forcing the original equation to be false.


Reposting this from last thread since you never answered it.
No, they are not true statements. Any physicist will tell you that a black hole comes to a point of singularity. The mass defines the event horizon, as you know. Just use logic- how can density affect mass? However, let's talk about math (since you brought it up from a mathematical point of view.)

Infinity is everything and nothing at the same time. If you multiply or divide by infinity you are left with...infinity- everything and nothing. This applies to every number no matter how hard you look at it, including zero.

As you may know, funny things happen when you divide by zero. This spills over into the real world with black holes.

Are they possible mathematically? No.

Are they there? Yes.


You make good points, but some things are simply unexplainable and must be left as scientific phenomina (like what I said about black holes.)
