How can two Black holes fusion and consist a supermassive Black Hole

In summary, two black holes can merge to form a single black hole, but there is no fusion involved. The resulting black hole's mass would depend on the original sizes of the two black holes. If the black holes are Schwarzschild or Reissner black holes and collide head-on, the resulting black hole will also be a Schwarzschild or Reissner black hole. However, if they are Kerr or Newman black holes, the merging process is more complex and can result in a singular ring.

I'm not sure what you mean by "fusion". If two black holes come together, they merge to form a single black hole. There is no fusion involved. Whether or not it is super massive would depend on their original sizes but probably one of them would have to already be super massive.

I'm asking if the black holes can United , Can the Curvatures of spacetime United and how ?

What part of post #2 did you not understand?

The OP is probably wondering about the details like when a sun comes to close to a black hole and there's a stream of material from the sun being sucked into the black hole.

For two black holes neither will give up material and so they'll act like two point masses coming together. The event horizon will look like two spheres merging into one larger one if you could even see it.

Thanks :smile:

Black hole singularities can simply collide only if both are Schwarzschild or Reissner black holes, AND they are colliding along straight line between the point masses. Then the result is also a Schwarzschild or Reissner black hole.

But what happens when two Kerr or Newman black holes merge? How do the two separate ring singularities evolve into one ring singularity?

Thank you for information But i didn't understand 'Schwarzschild or Reissner black hole ' and 'Kerr or Newman black holes'
 

1. How do two black holes fuse together?

When two black holes come close enough to each other, they start to orbit each other due to their strong gravitational pull. As they continue to orbit, they lose energy in the form of gravitational waves and eventually merge to form a single, larger black hole.

2. What is the process of black hole fusion?

The process of black hole fusion, also known as a merger, involves the two black holes orbiting each other, losing energy in the form of gravitational waves, and eventually colliding to form a single, more massive black hole.

3. How does the fusion of black holes lead to a supermassive black hole?

When two black holes merge, they combine their masses and the resulting black hole is larger than the sum of its parts. This process can repeat multiple times, with more black holes merging, leading to the formation of a supermassive black hole.

4. Can any two black holes fuse together to form a supermassive black hole?

Not all black holes are capable of merging and forming a supermassive black hole. The two black holes need to have similar masses and spin in the same direction in order to successfully merge.

5. What is the significance of supermassive black holes in the universe?

Supermassive black holes play a crucial role in the formation and evolution of galaxies. They are thought to be at the center of most galaxies, including our own Milky Way, and their immense gravitational pull helps to shape the structure and movement of stars and gas within the galaxy.
