Black Hole Singularity: Infinite Mass & Merging Supermassive Black Holes

In summary: Its gravity is strong because of its mass and density, but not infinite. The concept behind a black hole is similar to a hole in a trampoline, where its mass warps spacetime and causes other objects to be pulled towards it. Merging with another black hole can create a supermassive black hole, but the total mass of the two black holes remains the same.

If the Singularity Has Infinite Mass, How Does Merging With Another Black Hole Create "Suoermassive" Black Holes? Infinite Plus Infinite Is Infinite. No Increase.

Wait. That Would Be Infinite Gravity Instead?

A black hole has finite mass. You are probably thinking of the density of the singularity...

At the center of a black hole as described by general relativity lies a https://www.physicsforums.com/wiki/Gravitational_singularity , a region where the spacetime curvature becomes infinite.[54] For a non-rotating black hole, this region takes the shape of a single point and for a https://www.physicsforums.com/wiki/Rotating_black_hole , it is smeared out to form a https://www.physicsforums.com/wiki/Ring_singularity lying in the plane of rotation.[55] In both cases, the singular region has zero volume. It can also be shown that the singular region contains all the mass of the black hole solution.[56] The singular region can thus be thought of as having infinite https://www.physicsforums.com/wiki/Mass_density .

It has a specific mass, but theoretically infinite density. The concept behind a black hole is if you rolled a ball on a trampoline it would warp the surface, and it would pull other balls to it. A black hole is essentially a hole in the trampoline.

A black hole doesn't have infinite gravity either.
 

What is a black hole singularity?

A black hole singularity is a point in space where the gravitational pull becomes infinitely strong. It is surrounded by an event horizon, which is the point of no return for any object or light that gets too close.

Does a black hole singularity have infinite mass?

Yes, a black hole singularity is believed to have infinite mass due to the fact that the gravitational pull becomes infinitely strong at this point.

What happens when two black holes merge and their singularities combine?

When two black holes merge, their singularities also combine to form a larger singularity. This results in an even stronger gravitational pull and a larger event horizon.

Can a black hole singularity merge with a supermassive black hole?

Yes, it is possible for a black hole singularity to merge with a supermassive black hole. This can happen when two galaxies, each with a supermassive black hole at its center, merge together.

What are the implications of infinite mass in a black hole singularity?

The concept of infinite mass in a black hole singularity has significant implications for our understanding of gravity and the laws of physics. It also raises questions about the ultimate fate of the universe and the possibility of time travel.
