What would happen if two black holes get close and eventually collide together?

Answer 1

the larger will eat the smaller one.

not much will happen.

Answer 2

It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it. However, we do know that a black hole merger would produce tremendous energy and send massive ripples through the space-time fabric of the Universe. These ripples are called gravitational waves.

Nobody has witnessed a collision of black holes yet. However, there are many black holes in the Universe and it is not preposterous to assume that they might collide. In fact, we know of galaxies in which two supermassive black holes move dangerously close to each other. Theoretical models predict that these black holes will spiral toward each other until they eventually collide.

Gravitational waves have never been directly observed. However, they are a fundamental prediction of Einstein's theory of general relativity. Detecting them would provide an important test of our understanding of gravity. It would also provide important new insights into the physics of black holes. Large instruments capable of detecting gravitational waves from outer space have been built in recent years. Even more powerful instruments are under construction. The moment they detect their first gravitational wave, you are sure to hear about it!

Answer 3

A relativistic effect sets in when two bodies of such immense mass gets close to one another. They lose energy as gravity waves. This causes them to spiral closer and closer until they merge and become one object with the combined mass of both. Light can´t escape so there wouldn´t be much of a light show. This sort of thing would have happened many times since many galaxies have been found to harbor super massive black holes in their centers. They can be millions of times more massive than the sun yet the most massive stars can only be about 100 solar masses. So black hole mergers must have taken place.

Answer 4

They would merge and create one black hole that was the total mass of the 2 that collided.
The event horizon is a direct function of the mass of the black hole, so the new one would have a larger-diameter event horizon than the 2 original ones.

Answer 5

The two black holes would form a single black hole with a mass equal to the masses of the two black holes that formed it. Contrary to what's been said, neither black hole swallows the other. They simply merge, and in the process, give off extremely powerful gravitational waves, according to theory.

Answer 6

It is theorized that this happens quite regularly in the vastness of our universe. What happens is that they join together to make a single larger (if that's how you want to imagine it) black hole. In theory, a black hole has no actual size, but is a place where space and gravity meet as a singularity. No one really knows what goes on there but the power of a black hole can be estimated by its gravitational effect on nearby stars.

Answer 7

The two individual black holes would merge and become one larger black hole, with a mass equal to that of the original two combined.

Answer 8

They would be more inclined to orbit their center of mass rather than collide, however, such collisions due take place. The more massive black hole would consume the less massive one.

Answer 9

They smash together, forming a blue-white sub-universe in the tenth dimension.



Really!
