Black Holes Uniting: How Do They Crash?

In summary, black holes can merge if they come close to each other, resulting in a single, larger black hole. The event horizons merge when they collide, and the singularities may also collide or merge afterwards. Gravitational attraction is what brings black holes together, just as it does with other celestial objects. Additional dimensions in the universe do not play a role in black hole merging.

if black hole crash they unite to one b.h
here, how can this two crash??
universe has a lot of dimension so
i think it is hard to
and when they crash, crash with only singularity??

The universe has 3 spatial and 1 time dimensions, for a total of 4. There might be additional dimensions, but they don't play a role in black hole merging.

Black holes can merge, if they come very close to each other. They become a single, bigger black hole in this case.

one more..
when they collide they collide with singularity or in the event horizon??

The event horizons merge. The singularities probably collide/merge afterwards, too, but that cannot be observed from the outside.

gravitational attraction brings black holes together just the same as it brings cosmic dust together to form stars, planets, and black holes themselves...
 

1. What are black holes?

Black holes are regions in space where the gravitational pull is so strong that nothing, including light, can escape from it. They are formed when a massive star dies and its core collapses under its own gravity.

2. How do black holes crash?

Black holes can crash when two or more of them are in close proximity to each other. The gravitational force between them can cause them to spiral towards each other and eventually collide.

3. What happens when two black holes collide?

When two black holes collide, they merge into a larger black hole. This process releases a tremendous amount of energy in the form of gravitational waves that ripple through space.

4. How do we detect black hole collisions?

We can detect black hole collisions through the detection of gravitational waves. These are ripples in the fabric of space-time that are produced by the merging of black holes. They can be detected using specialized detectors such as LIGO (Laser Interferometer Gravitational-Wave Observatory).

5. Is it possible for black holes to unite without merging?

Yes, it is possible for black holes to unite without merging. This can happen when two black holes are in close proximity but do not have enough momentum to merge. In this scenario, they can form a binary system, orbiting each other indefinitely.
